Beschreibung
Zusammenfassung:	A hydraulic system having an actuator having a piston and associated rod forming head and rod chambers and being adapted to move between retracted and extended positions within a cylinder, and first and second sources of fluid. A first pump provides fluid from the first source to the head chamber at a first pressure. At least one valve provides fluid from the second source at a second pressure to supplement fluid provided to the head chamber from the first pump when the second pressure is greater than the first pressure.
