A valve module for an operating fluid container system. The valve module has a housing which has a first connection for fluidically connecting to an operating fluid container interior, a second connection for fluidically connecting to a filler tube, and a third connection for at least indirectly fluidically connecting to the atmosphere. The valve module comprises the following features: the first connection is connected to the second connection and the third connection within the housing in a fluidic manner in each case; the second connection is connected to the third connection within the housing in a fluidic manner; and the first connection, the second connection, and the third connection can each be adjusted independently of one another between an open position, in which fluid communication through the respective connection is allowed, and a closed position, in which fluid communication through the respective connection is prevented.

What is claimed is: 1. A valve module for an operating liquid container system, the valve module comprising: a housing; the housing having a first port configured to be fluidically connected to an operating liquid container interior; the housing having a second port configured to be fluidically connected to a filler pipe; the housing having a third port configured to be fluidically connected to atmosphere; the first port is fluidically connected, within the housing, in each case to the second port and to the third port; the second port is fluidically connected, within the housing, to the third port; and a first valve apparatus arranged between the first port and the second port and fluidically connected to the first port and to the second port; the first valve apparatus actuatable between an open position, in which a fluid flow between the first port and the second port is made possible by the first valve apparatus, and a closed position, in which the fluid flow between the first port and the second port is prevented by the first valve apparatus; a second valve apparatus arranged between the first port and the third port and fluidically connected to the first port and to the third port; and the second valve apparatus actuatable between an open position, in which a fluid flow between the first port and the third port is made possible by the second valve apparatus, and a closed position, in which the fluid flow between the first port and the third port is prevented by the second valve apparatus; the first valve apparatus has at least two first valve devices which are fluidically connected to one another in parallel, whereby each of the at least two first valve devices is arranged to receive a respective portion of fluid flow from a shared fluid line; and each first valve device is actuatable between an open position and a closed position. 2. The valve module as claimed in claim 1 , wherein the at least two first valve devices have mutually different free opening cross-sectional areas. 3. The valve module as claimed in claim 1 , wherein: the second valve apparatus has at least two second valve devices which are fluidically connected to one another in parallel; and each second valve device is actuatable between an open position and a closed position. 4. The valve module as claimed in claim 3 , wherein the at least two second valve devices have mutually different free opening cross-sectional areas. 5. The valve module as claimed in claim 1 , wherein the first valve apparatus and/or the second valve apparatus are/is electrically actuatable between the open position and the closed position. 6. The valve module as claimed in claim 1 , further comprising: the housing having a fourth port configured to be fluidically connected to an intake tract of an internal combustion engine; a third valve apparatus arranged between the third port and the fourth port and fluidically connected to the third port and to the fourth port; and the third valve apparatus actuatable between an open position, in which a fluid flow between the third port and the fourth port is made possible by the third valve apparatus, and a closed position, in which the fluid flow between the third port and the fourth port is prevented by the third valve apparatus. 7. The valve module as claimed in claim 6 , wherein: the third valve apparatus has at least two third valve devices which are fluidically connected to one another in parallel; and each third valve device is actuatable between an open position and a closed position. 8. The valve module as claimed in claim 7 , wherein the at least two third valve devices have mutually different free opening cross-sectional areas. 9. The valve module as claimed in claim 1 , further comprising the following features: a ratio of a first cross-sectional area of the first port to a second cross-sectional area of the second port amounts to between 0.64 and 41; and/or a ratio of a first cross-sectional area of the first port to a third cross-sectional area of the third port amounts to between 0.5 and 4. 10. A valve module for an operating liquid container system, the valve module comprising: a housing; the housing having a first port configured to be fluidically connected to an operating liquid container interior; the housing having a second port configured to be fluidically connected to a filler pipe; the housing having a third port configured to be fluidically connected to atmosphere; the first port is fluidically connected, within the housing, in each case to the second port and to the third port; the second port is fluidically connected, within the housing, to the third port; the first port and the second port and the third port are each independently of one another adjustable in each case between an open position, in which fluid communication through the respective port is made possible, and a closed position, in which fluid communication through the respective port is prevented; the housing has a fourth port configured to be fluidically connected to an intake tract of an internal combustion engine; the first port is fluidically connected, within the housing, to the fourth port; the second port is fluidically connected, within the housing, to the fourth port; the third port is fluidically connected, within the housing, to the fourth port; and the fourth port is adjustable between an open position, in which fluid communication through the fourth port is made possible, and a closed position, in which fluid communication through the fourth port is prevented. 11. The valve module as claimed in claim 10 , wherein the first port and/or the second port and/or the third port and/or the fourth port are/is each actuatable electrically between the open position and the closed position. 12. The valve module as claimed in claim 10 , wherein the first port is designed as a first valve and/or the second port is designed as a second valve and/or the third port is designed as a third valve and/or the fourth port is designed as a fourth valve. 13. The valve module as claimed in claim 12 , wherein the first valve and/or the second valve and/or the third valve and/or the fourth valve are each designed as a proportional valve and are/is electrically adjustable in continuous fashion between an open position and a closed position. 14. The valve module as claimed in claim 10 , wherein the first port and/or the second port and/or the third port and/or the fourth port are/is adjustable in discrete fashion between the respective open position thereof and the respective closed position thereof. 15. The valve module as claimed in claim 10 , wherein the valve module has a liquid-vapor separator, via which the first port and the second port are fluidically connected to the third port and/or the fourth port. 16. An operating liquid container system for a motor vehicle, comprising: an operating liquid container having an operating liquid container interior; a filler pipe to fill the operating liquid container interior with an operating liquid; a valve module; the valve module comprising a housing; the housing having a first port fluidically connected to the operating liquid container interior; the housing having a second port fluidically connected to the filler pipe; and the housing having a third port fluidically connected to atmosphere; the first port is fluidically connected, within the housing, in each case to the second port and to the third port; the second port is fluidically connected, within the housing, to the third port; the first port is fluidically connected to the o
