Patent ID: 7484814

Claim:
A hydraulic system comprising: a supply conduit receiving fluid under pressure from a source; a return conduit for conveying fluid back to the source; a first hydraulic actuator and a second hydraulic actuator; a first control valve connected to the supply conduit, the return conduit and the first hydraulic actuator, and controlling flow of fluid between the first hydraulic actuator and both of the supply conduit and the return conduit; a second control valve connected to the supply conduit, the return conduit and the second hydraulic actuator, and controlling flow of fluid between the second hydraulic actuator and both of the supply conduit and the return conduit; a first load sense passage receiving a first load pressure indicating a force acting on the second hydraulic actuator and being isolated from effects of a force acting on the first hydraulic actuator; and an anti-stall valve coupled to the supply conduit and the return conduit and providing a flow path there between in response to pressure in the first load sense passage exceeding a predefined magnitude.
