The piston of the hydraulic cylinder moves downward (the weight falls). Hydraulic oil enters the upper end of the hydraulic cylinder through explosion-proof electromagnetic reversing valve, and oil returns to the tank through balance valve, hydraulic control one-way valve, throttle valve and explosio...
TheHydraulic actuator working principleis, it uses liquid pressure to work instead of instrument air pressure to provide a force on the diaphragm to move the valve actuator, then to the stem of the position valve. Almost all types of hydraulic actuators use a piston instead of a diaphragm for...
In this review paper, a basic introduction to the civil aircraft piston pump is presented,including the classification, structure, working principle, design features, and achievements by some research groups. Then, the future directions of the aircraft pump are reported from various perspectives. ...
