ABSTRACT:
A linear hydraulic actuator has a reciprocating pump which provides pressurized hydraulic fluid contained in a reservoir to a hydraulic cylinder in which slides a piston which supplies the actuator output. A diverter valve in flow communication with the pressurized hydraulic fluid has an adjustment shaft allowing manual adjustment of the rate of flow of pressurized hydraulic fluid to the cylinder. Preferably the pump is immersed in the hydraulic fluid held by the reservoir, and the adjustment shaft of the diverter valve penetrates a wall of the reservoir to allow external adjustment of the diverter valve.
