Variable configuration traction valve

摘要

A traction valve is provided for use in combination with a relay valve. The traction valve includes a body configured for connection to a housing of the relay valve and defining inlet, outlet and traction supply ports. A first fluid control valve used for traction control is supported on the body and includes a valve member that alternately permits and prevents fluid communication between the traction supply and outlet ports in the body. The body and the first fluid control valve are configured to receive any of a plurality of interchangeable second fluid control valves between the inlet port in the body and the first fluid control valve. Each of the plurality of interchangeable second fluid control valves is configured to perform a different function such that the traction valve assumes different configurations upon assembly of the various second fluid control valves with the body and the first fluid control valve.

1. A traction valve, comprising:
a body defining an inlet port, an outlet port, and a traction supply port, said outlet port configured for fluid communication with a fluid chamber defined in a housing of a relay valve; a first fluid control valve supported on said body, said first fluid control valve including a valve member configured to move between a first position preventing fluid communication between said fraction supply port and said outlet port and a second position permitting fluid communication between said traction supply port and said outlet port; wherein said body and said first fluid control valve are configured to receive any of a plurality of interchangeable second fluid control valves between said inlet port in said body and said first fluid control valve, each of said plurality of interchangeable second fluid control valves configured to perform a different function such that said traction valve assumes a first configuration upon assembly of one valve of said plurality of interchangeable second fluid control valves with said body and said first fluid control valve and a second configuration, different from said first configuration, upon assembly of another valve of said plurality of interchangeable second fluid control valves with said body and said first fluid control valve wherein said body includes a first portion having means for attaching each of said plurality of interchangeable second fluid control valves to said body and a second portion defining said inlet port, said second portion configured for attachment to each of said plurality of interchangeable second fluid control valves.
