Fluid operated actuator |
摘要 |
A fluid operated actuator (100) is provided. The fluid operated actuator (100) includes a body (101) forming a piston bore (201). A piston (111) is movable within the piston bore (201). The fluid operated actuator (100) also includes a valve unit (105) coupled to the body (101) and including a fluid inlet port (217), a fluid exhaust port (220), and a valve member (214) configured to selectively open a fluid flow path between the fluid inlet port (217) and the piston bore (201) and between the exhaust port (220) and the piston bore (201). The fluid operated actuator (100) can also include a control unit (106) coupled to the body (101) and the valve unit (105). The control unit (106) can include a pilot input port (317a) in fluid communication with the fluid inlet port (217). The control unit (106) can also include first and second pilot output ports (317b, 317c) in fluid communication with the valve member (214). Further, the control unit (106) can include a pilot valve (230) adapted to open a fluid flow path between the pilot input port (317a) and one or more of the first and second pilot output ports (317b, 317c) in order to actuate the valve member (214). |
