Abstract

See full text

A pump control assembly having a flow control assembly disposed between the first end of a load sensing valve and a fluid pump is disclosed. The flow control assembly may include an orifice, a first valve assembly, and a second valve assembly. When the first valve assembly is in an open position and the second valve assembly is in a first position, fluid passing through the orifice is directed to a fluid reservoir and to the load sensing valve. When the first valve assembly is in a closed position and the second valve assembly is in a second position, all fluid passing through the orifice is directed to the load sensing valve. An electronic controller can be configured to transmit an output current to the first and second valve assemblies in response to an operational parameter of a prime mover supplying power to the fluid pump.
