Abstract:
A hydraulic system having a solenoid bleed valve for bleeding air out of the system is provided. The present invention is a hydraulic system having an actuator, a coupling operably associated with the actuator, and a first solenoid valve operably associated with the actuator and the coupling, where the first solenoid is operable to control pressure applied to the coupling. The present invention also includes a second solenoid valve operably associated with the actuator and the first solenoid, where the second solenoid is operable to relieve pressure.
