Patent ID: 8435010

Claim:
A pump control assembly comprising: a fluid pump assembly including: a fluid pump having a fluid inlet and a fluid outlet, the fluid pump including a variable displacement mechanism; a load sensing valve adapted to adjust the position of the variable displacement mechanism, the load sensing valve having a first end and an oppositely disposed second end; an actuator in fluid communication with the fluid pump assembly; a position sensor for monitoring the position of the actuator; a ramping valve providing selective fluid communication between the fluid outlet of the fluid pump and the first end of the load sensing valve to adjust the variable displacement mechanism; and an electronic control unit in electrical communication with the position sensor and the ramping valve, wherein the electronic control unit is configured to transmit an output current signal including a ramp-down portion that decreases over a predetermined time interval, the output current signal being sent to the ramping valve in response to the position of the actuator to gradually adjust the variable displacement mechanism to a neutral position.
