Patent ID: 8479769

Claim:
A hydraulic LS flow control valve, comprising: a fluid connector arrangement of a pressure supply connector, a return flow connector, a section load sensing connector, first and second control connectors and first and second utility connectors; at least one control connected to said connectors to trigger said connectors, said control including a first valve spool and a first pressure compensator connected upstream thereto in a flow direction to said first utility connector and a second valve spool and a second pressure compensator connected upstream thereto in a flow direction to said second utility connector, each said valve spool and each said pressure compensator being biased by springs to centered, initial positions thereof, each said pressure compensator being operable by a LS pressure conveyed simultaneously to a first connection side of the respective valve spool, each said valve spool being operable by a respective control pressure of a respective pilot valve; a line tapping pressure between each said valve spool and the respective pressure compensator being connected to a connection side of the respective pressure compensator to act in an opposite direction of the LS pressure applied thereto; and a second connection side of each said valve spool being connected to said return flow connector routed essentially along a middle axis of a valve housing containing said valve spools and said pressure compensators between said valve spools and the respective pressure compensators in the initial position thereof.
