ABSTRACT:
A hydraulic control system for actuating a switch or related device including an actuator assembly having a housing with a member movable therein and connected to the switch for movement therewith between first and second positions responsive to the application of hydraulic pressure in the housing on opposite sides of the movable member. The hydraulic control system includes a block member having inlet and outlet ports and passageways therebetween, the inlet port being connected to a source of hydraulic pressure, a plurality of control devices mounted on the block member and selectively energizable for establishing communication between the inlet port and a selected one of the outlet ports, the outlet ports being connected to the actuator housing to communicate with the housing on opposite sides of the movable member, and hydraulic pressure restrictor devices mounted on the block member at positions to predeterminately restrict hydraulic communication between the inlet port and the selected one of the outlet ports to control the speed of movement of the movable member in the actuator housing.
