Abstract

A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts.

First claim

What is claimed is:

1. A valve system adaptable for brake control of different pressure-medium-operated vehicle brake systems, the valve system comprising:
a set of a plurality of different inserts; and
a valve device configured to receive an insert selected from the set of the plurality of different inserts, the valve device including:
a housing having a housing block and a housing cover, the housing block having a plurality of pressure medium ducts, the housing cover having at least one pressure medium bore, the housing block being mountable to the housing cover in one direction and configured to receive the selected insert in a different direction; and
a relay valve configured to increase a pressure medium flow rate of air pressure present at at least one of the plurality of pressure medium ducts, at least two pressure medium ducts of the plurality of pressure medium ducts being configured to pneumatically connect to a first pressure medium bore of the at least one pressure medium bore and to a pneumatic port of the selected insert to define a pressure medium path,

wherein each insert of the set of the plurality of different inserts provides a different pressure medium path when received by the valve device.

2. The valve system as claimed in claim 1 , wherein at least one of the plurality of pressure medium ducts is assigned a function from a group of functions consisting of (i) aeration, (ii) ventilation, (iii) conduction of control pressure or redundancy pressure, (iv) conduction of brake pressure, and (v) not used, depending on the selected insert received by the valve device.

3. The valve system as claimed in claim 1 , wherein the at least on pressure medium bore further comprises a second pressure medium bore, and
wherein operability of the second pressure medium bore is based on the selected insert received by the valve device.

4. The valve system as claimed in claim 1 , wherein the plurality of pressure medium ducts comprises a plurality of port ducts leading to ports on the housing,
wherein the defined pressure medium path comprises at least two of the plurality of port ducts, and
wherein operability of the port ducts of the pressure medium path is based on the selected insert received by the valve device.

5. The valve system as claimed in claim 1 , wherein the relay valve is disposed in the housing block.

6. The valve system as claimed in claim 1 , wherein each pressure medium duct of the plurality of pressure medium ducts is dissimilar from other ones of the plurality of pressure medium ducts, and
wherein the housing block and the housing cover are configured to surround and clamp to the insert.

7. The valve system as claimed in claim 1 , wherein each insert of the set of the plurality of different inserts is configured to be inserted in the housing block, comprises at least one of valve cartridges and valve blocks, and includes at least one valve controllable to at least one of open and block a corresponding pressure medium path produced when received by the valve device.

8. The valve system as claimed in claim 7 , wherein each of the at least one of valve cartridges and valve blocks has a hardened injection-molded compound or cast compound that at least partially surrounds at least one valve therein.

9. The valve system as claimed in claim 7 , wherein the at least one of valve cartridges and valve blocks have (i) at least one of different and identical valves, and (ii) connecting ducts different from one another.

10. The valve system as claimed in claim 7 , wherein each of the at least one of valve cartridges and valve blocks has (i) at least one connecting duct, the at least one connecting duct of one of the at least one of valve cartridges and valve blocks being one of dissimilar and identical to the at least one connecting duct of another one of the at least one of valve cartridges and valve blocks, and (ii) at least one valve, the at least once valve of one of the at least one of valve cartridges and valve blocks being one of dissimilar and identical to the at least one valve of another one of the at least one of valve cartridges and valve blocks.

11. The valve system as claimed in claim 1 , wherein, depending on the selected insert received by the valve device, the valve device is configured as a device from the group consisting of (i) a relay modulator from an electropneumatic parking brake, (ii) a relay modulator for an electronically regulated brake system, (iii) a relay modulator for a pneumatic brake system with at least one of an anti-lock brake system and traction control system, (iv) an electromagnetic relay valve, and (v) a relay valve.

12. The valve system as claimed in claim 4 , wherein the ports on the housing are configured to connect to at least one of (i) a compressed-air reservoir, (ii) a vent, (iii) a brake pedal device, and (iv) at least one brake cylinder.

13. The valve system as claimed in claim 1 , wherein the housing is formed at least partially from metal, and the plurality of pressure medium ducts is formed at least partially by bored in the housing block.

14. A vehicle brake system, comprising:
pressure-medium-operated brake cylinders, and
the valve system as claimed in claim 1 .

15. A vehicle, comprising:
the vehicle brake system as claimed in claim 14 .

16. The valve system as claimed in claim 1 , wherein the insert is a valve block.

17. A vehicle, comprising:
the valve system as claimed in claim 1 .

18. The valve system as claimed in claim 7 , wherein the at least one valve is an electromagnetic valve.

19. The valve system as claimed in claim 8 , wherein the hardened injection-molded compound or cast compound is a plastic injection-molded compound or cast compound.

20. The valve system as claimed in claim 13 , wherein the metal is aluminum.
