摘要： The invention relates to a reciprocating piston pump for delivering a liquid. The pump includes a solenoid with an actuator and an outlet port. A check valve with a seat body is assigned to the outlet port for keeping a return flow of the liquid out of the reciprocating piston pump. The seat body bears an impact damping face at a front face facing away from a valve seat of the check valve, and the valve seat of the check valve and the impact damping face are made from the same elastomer material.

摘要： Electrically controlled fuel injection systems should be able to operate at low voltage. In order to operate an electrically controlled fuel injection system at low voltage, the voltage available to an electrical actuator is monitored. The electrical actuator is coupled to a valve positioned within a passageway in which high pressure actuation fluid flows to and from an hydraulically actuated device, such as a fuel injector and/or an engine brake. If the voltage available to the electrical actuator falls below a predetermined voltage, the pressure differential across the valve is reduced. Although the principal application of the present invention is in the fuel injection system, the present invention has application in any electrically controlled fluid system at low voltage.

摘要： A control system adapted to control an actuator between extended and retracted positions has a fluid control valve connected to the actuator a source of high pressure fluid and a reservoir. The fluid control valve is movable between a first position at which the actuator is connected back to the fluid reservoir adapted and a second position operable to connect the actuator to a high pressure actuation fluid source. An electronic control module is connected in control communication with the fluid control valve and adapted to automatically generate a control signal to position the control valve at the second position in response to an elapsed time being passed at which the fluid control valve is at the first position is greater than a predetermined time.
