Abstract
A hydraulic system comprises a pump having a fluid feed end a fluid release. Hydraulic actuator has an advance port and a retract port A directional converter is fluidically coupled between the pump and the hydraulic actuator. The converter has a housing having a plurality of fluid passages that terminates in a pump outlet port, a pump inlet port, a first actuator port, and a second actuator port. A plurality of valves is disposed within the fluid passages. The plurality of valves has a first position and a second position. In the first position, a fluid flow direction at the first actuator port is into said housing from the actuator and a second fluid direction and a second actuator port is out of the housing. When the switches are in a second position the fluid flow direction is out of the housing at The second actuator port.
