Abstract
A hydraulic pump system includes a pump control system operable to reduce electric current required at the start of the pump and reduce starting torque for the pump. The pump control system can include a gap between a spring seat and a valve spool such that the valve spool need not overcome a biasing force from a swash plate when the swash plate changes from its maximum displacement position to its neutral position.
