- Which of the following hydraulic control valves belongs to pressure control valve （ ）. A: Unloading valve B: overflow throttle valve C: Hydraulic control check valve D: Low pressure selector valve
- Relief valve is used to increase the hydraulic pressure in the system to a desired value.
- In hydraulic transmission, the hydraulic control valve used to control the pressure, flow and direction of liquid is ( ). A: Power plant B: control unit C: auxiliary device D: Actuator
- All ground spoilers are powered by hydraulic system _____ through a control valve and a bypass valve.
- In order to ensure that the pressure difference between the front and rear of the throttle valve remains unchanged when the load changes, the flow through the throttle valve is basically unchanged. The throttle valve is often connected with ( ) to form a speed control valve, or the throttle valve and ( ) are connected in parallel to form a bypass speed control valve.
