Abstract

An improved venting and/or air admission valve for an operating fluid reservoir, wherein different shutoff levels (SOH) can be achieved. The venting and/or air admission valve is distinguished by the fact that it comprises an adapter, which can be fastened on an operating fluid reservoir wall, and that a valve housing of the venting and/or air admission valve can be fastened on the adapter in such a way that the adapter is arranged between the operating fluid reservoir wall and the valve housing.

First claim

What is claimed is:

1. A valve system, comprising:
a valve configured to operate as at least one of a venting valve and an air admission valve;
the valve including a hollow valve housing, which is configured to be located in an interior of an operating fluid reservoir;
the valve housing including at least one communication opening for fluid exchange between a valve housing interior and the interior of the operating fluid reservoir;
the valve housing including a ventilation opening for gas exchange between the valve housing interior and a ventilation line;
the valve including a single valve body arranged in the valve housing interior, whereby the valve only has one valve body;
in an installed position of the valve in the operating fluid reservoir, the valve body is configured to be at a distance from the ventilation opening when an operating fluid level of operating fluid within the interior of the operating fluid reservoir is below a shutoff level, such that the valve housing interior and the ventilation line are in fluid communication;
in the installed position of the valve in the operating fluid reservoir, the valve body is configured to be subjected to a lift from the operating fluid in the valve housing interior such that the valve body closes the ventilation opening when the operating fluid level within the interior of the operating fluid reservoir is above the shutoff level, such that the valve housing interior and the ventilation line are not in fluid communication;

the valve comprises an adapter, which is configured to be fastened on an inner face of an operating fluid reservoir wall of the operating fluid reservoir, wherein the inner face faces the interior of the operating fluid reservoir to contain the operating fluid and is disposed opposite an outer face of the tank;
the valve housing configured to be fastened on the adapter such that the adapter is arranged between the operating fluid reservoir wall and the valve housing;
the adapter comprises a plurality of first fastening devices, wherein the plurality of the first fastening devices are spaced apart from each other angularly around a longitudinal axis of the adapter such that the plurality of the first fastening devices are not aligned with each other along the longitudinal axis of the adapter;
the valve housing comprises a plurality of second fastening devices, wherein the plurality of the second fastening devices are spaced apart from each other angularly around a longitudinal axis of the valve housing such that the plurality of second fastening devices are not aligned with each other along the longitudinal axis of the valve housing;
the valve housing configured to be fastened on the adapter by each one of the plurality of the second fastening devices and each one of the plurality of the first fastening devices;
at least one of the plurality of first fastening devices includes a latching device and at least one of the plurality of second fastening devices includes a latching opening;
the adapter is configured to be connected at least one of positively and materially to the operating fluid reservoir wall; and
wherein, during the valve housing being fastened on the adapter, the latching device of the adapter forces the side wall of the valve housing to move until the latching device latches into the latching opening of the valve housing.

2. The valve system as claimed in claim 1 , further comprising:
the operating fluid reservoir with the operating fluid reservoir wall;
the valve housing located in the interior of the operating fluid reservoir;
a vent line located in the interior of the operating fluid reservoir;
the vent line in fluid communication with the valve via the ventilation opening;
the valve in the installed position in the operating fluid reservoir;
the adapter fastened on the inner face of the operating fluid reservoir wall of the operating fluid reservoir; and
the valve housing fastened on the adapter such that the adapter is arranged between the operating fluid reservoir wall and the valve housing.

3. The valve system as claimed in claim 1 , wherein:
the valve housing is configured to be fastened on the adapter by each one of the plurality of the second fastening devices being fastened with a corresponding one of the plurality of the first fastening devices to provide a plurality of fastening connections.

4. The valve system as claimed in claim 1 , wherein:
the plurality of the first fastening devices are not longitudinally spaced apart from each other along the longitudinal axis of the adapter; and
the plurality of the second fastening devices are not longitudinally spaced apart from each other along the longitudinal axis of the adapter.

5. The valve system as claimed in claim 1 , wherein:
the plurality of the first fastening devices are spaced apart from each other angularly around the longitudinal axis of the adapter such that the plurality of the first fastening devices are on opposing sides of the adapter; and
the plurality of the second fastening devices are spaced apart from each other angularly around the longitudinal axis of the valve housing such that the plurality of the second fastening devices are on opposing sides of the valve housing.

6. The valve system as claimed in claim 1 , wherein:
the adapter is configured to be fastened on the inner face of the operating fluid reservoir wall of the operating fluid reservoir without extending through the operating fluid reservoir wall of the operating fluid reservoir.

7. The valve system as claimed in claim 1 , wherein:
the latching opening comprises a through-hole formed in a wall of the adapter.

8. The valve system as claimed in claim 1 , wherein:
a mounting end of the adapter is configured to be fastened on the inner face of the operating fluid reservoir wall of the operating fluid reservoir;
the plurality of the first fastening devices are disposed on a side wall of the adapter;
the plurality of the second fastening devices are disposed on a side wall of the valve housing;
wherein, when the valve housing is fastened on the adapter, the adapter side wall has a terminal end which faces towards the valve housing, and the at least one latching device is disposed on the adapter side wall remote from the terminal end of the adapter side wall which faces towards the valve housing; and
wherein, when the valve housing is fastened on the adapter, the valve housing side wall has a terminal end which faces towards the mounting end of the adapter, and the at least one latching opening is disposed on the valve housing side wall remote from the terminal end of the valve housing side wall which faces towards the mounting end of the adapter.

9. The valve system as claimed in claim 1 , wherein:
the valve body is configured to be subjected to the lift from the operating fluid in a lift direction;
the plurality of the first fastening devices are disposed on a side wall of the adapter;
the plurality of the second fastening devices are disposed on a side wall of the valve housing; and
wherein the adapter side wall and the valve housing side wall are parallel with one another in the lift direction of the valve body, and the at least one latching device and the at least one latching opening are disposed on the adapter and valve housing side walls which are parallel, respectively.

10. A valve system, comprising:
a valve configured to operate as at least one of a venting valve and an air admission valve;
the valve including a hollow valve housing, which is configured to be located in an interior of an operating fluid reservoir;
the valve housing including at least one communication opening for fluid exchange between a valve housing interior and the
