Title: Priority flow valve

Abstract: A priority valve utilized in a pressure and flow compensated variable displacement system which supplies priority flow to a priority motor and secondary flow to a secondary motor as long as the priority flow requirements are satisfied or the priority flow path is blocked. The priority valve utilizes the same flow control signal as the system pump including a fixed restriction in the signal line and a relief valve downstream of said restriction, set at a level below the maximum pressure level of the system so that when the priority motor is stopped, flow continues to the secondary motor.
