The needle valve in a fuel valve will （） when the fuel pressure action on the needle valve tapered face exerts a force lower than that of the spring compression.
举一反三
- The needle valve in the injector （） at a pre-set pressure which ensures that the fuel will atomize once it enters the cylinder.
- FMV is the short for ( ). A: Fuel Metering Valve B: Fuel Metering Vane C: Fuel Management Valve D: Fuel Metering Value
- A common trouble with the fuel pump plunger or fuel valve spindle is （）.
- 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. A: Pressure reducing valve B: constant pressure reducing valve C: overflow valve D: differential pressure relief valve
- 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
