Abstract

A valve arrangement for a fluidic supply of a fluid load, with several main valves designed for influencing fluid flows at the fluid ports, and with electrically controllable pilot valves designed for fluidic control of the main valves. A base body is assigned a connection plate lying opposite a connection face and having a fluid passage which leads into an operating port for the connection of a fluid load wherein, between the connection face and the connection plate there is provided a separate passage body which has at least one connection passage for a fluidically communicating link between at least one of the fluid ports and the operating port, and at least one connecting conduit for a fluidic coupling of at least two fluid ports.

First claim

The invention claimed is:

1. A valve arrangement for a fluidic supply of a fluid load, with several main valves which are connected, with fluidic communication, to respectively assigned fluid ports and which are designed for influencing fluid flows at the fluid ports, wherein the fluid ports are located at least partly on a connection face of a base body, and with electrically controllable pilot valves, which are designed for fluidic control of the main valves, wherein the base body is assigned a connection plate lying opposite the connection face and through which runs a fluid passage, which leads into an operating port for the connection of the fluid load wherein, between the connection face and the connection plate, there is provided a separate passage body which has at least one connection passage for a fluidically communicating link between at least one of the fluid ports and the operating port, and at least one connecting conduit for a fluidic coupling of at least two fluid ports, and
wherein the base body includes the connection plate, and wherein a locating shaft for the passage body is formed in the connection plate, wherein the passage body may be attached in at least one functional position for the fluidically communicating interconnection of the main valves with the operating port and the supply port and the air outlet port in the locating shaft.

2. The valve arrangement according to claim 1 , wherein at least one main valve or at least one pilot valve has a preset preferred position.

3. The valve arrangement according to claim 1 , wherein, in the connection plate, a further fluid passage is formed which opens out into a supply port or an air outlet port, and wherein, in the passage body, there is formed a further connection passage or a further connecting conduit for a fluidically communicating connection between at least one of the fluid ports and the supply port or the air outlet port or for a fluidic coupling of at least two further fluid ports.

4. The valve arrangement according to claim 3 , wherein there are formed in the passage body several connecting conduits, which are designed for presettable fluidic interconnection of the main valves with the operating port and the supply port and the air outlet port.

5. The valve arrangement according to claim 1 , wherein the main valves are similarly designed.

6. The valve arrangement according to claim 1 , wherein connection means corresponding to one another are located on the base body and on the passage body, and are designed for data interchange between an electronic memory device in the passage body and an electronic processing device in the base body.

7. A valve arrangement for a fluidic supply of a fluid load, with several main valves which are connected, with fluidic communication, to respectively assigned fluid ports and which are designed for influencing fluid flows at the fluid ports, wherein the fluid ports are located at least partly on a connection face of a base body, and with electrically controllable pilot valves, which are designed for fluidic control of the main valves, wherein the base body is assigned a connection plate lying opposite the connection face and through which runs a fluid passage, which leads into an operating port for the connection of the fluid load wherein, between the connection face and the connection plate, there is provided a separate passage body which has at least one connection passage for a fluidically communicating link between at least one of the fluid ports and the operating port, and at least one connecting conduit for a fluidic coupling of at least two fluid ports, and
wherein the separately formed connection plate is designed for attachment to the connection face and wherein the connection plate includes a locating shaft for the passage body, wherein the passage body may be attached in at least one functional position for the fluidically communicating interconnection of the main valves with the operating port and the supply port and the air outlet port in the locating shaft.

8. A valve arrangement for a fluidic supply of a fluid load, with several main valves which are connected, with fluidic communication, to respectively assigned fluid ports and which are designed for influencing fluid flows at the fluid ports, wherein the fluid ports are located at least partly on a connection face of a base body, and with electrically controllable pilot valves, which are designed for fluidic control of the main valves, wherein the base body is assigned a connection plate lying opposite the connection face and through which runs a fluid passage, which leads into an operating port for the connection of the fluid load wherein, between the connection face and the connection plate, there is provided a separate passage body which has at least one connection passage for a fluidically communicating link between at least one of the fluid ports and the operating port, and at least one connecting conduit for a fluidic coupling of at least two fluid ports, and
wherein a valve plate is connected to the connection plate at the operating port of the connection plate, the valve plate including at least one switching valve, which is designed to influence a fluid flow between a fluid source and a fluid load, wherein a fluidic control connection of the switching valve is in fluidically communicating connection with the operating port and wherein the valve plate is assigned at least one sensor means from the group: pressure sensor, flow sensor, temperature sensor, position sensor, wherein the sensor means are electrically connected to the connection plate or are accommodated in the connection plate.

9. A valve arrangement for a fluidic supply of a fluid load, with several main valves which are connected, with fluidic communication, to respectively assigned fluid ports and which are designed for influencing fluid flows at the fluid ports, wherein the fluid ports are located at least partly on a connection face of a base body, and with electrically controllable pilot valves, which are designed for fluidic control of the main valves, wherein the base body is assigned a connection plate lying opposite the connection face and through which runs a fluid passage, which leads into an operating port for the connection of the fluid load wherein, between the connection face and the connection plate, there is provided a separate passage body which has at least one connection passage for a fluidically communicating link between at least one of the fluid ports and the operating port, and at least one connecting conduit for a fluidic coupling of at least two fluid ports, and
wherein a valve plate is connected to the connection plate at the operating port of the connection plate, wherein the valve plate includes at least one switching valve, which is designed to influence a fluid flow between the operating port and a fluid load, wherein an electrical control connection of the switching valve is connected to a control interface and wherein the switching valve has a normally closed position.
