摘要： Responsiveness is improved in valve opening and valve closing of an electromagnetically driven intake valve unit in which a valve is provided on a pressurizing chamber side of a valve seat. The valve includes an annular abutting surface that abuts the valve seat to shut off a fuel intake passage and a bottomed cylindrical part provided at an inner peripheral part of the annular abutting surface. The bottomed cylindrical part is inserted into a fuel introduction hole formed in the valve housing inside the valve seat, and the outer surface of an end part of the bottomed cylindrical part is exposed to fuel in a low pressure fuel chamber provided upstream of the fuel introduction hole.

摘要： A high-pressure pump has a metering valve and a valve stopper. The stopper has a regulation portion which an end surface of the valve is brought into contact with. An outer diameter of the regulation portion is equal to an outer diameter of the outer peripheral surface of the valve. A cylindrical sleeve is disposed around the regulation portion. When the end surface of the valve is in contact with the regulation portion, the sleeve covers a tapered surface of the valve.

摘要： In usual hydraulic pumps, a separate assembly opening is provided for every valve of the hydraulic pump. This design causes sealing problems. It is proposed, that the fluid inlet valve and the fluid outlet valve can be assembled through a common assembly access port. Further, the fluid inlet valve and the fluid outlet valve can be arranged around a common cavity, or even within the same cavity, via the common assembly access port in the fluid working machine's body.

摘要： A method is disclosed for controlling a valve having a spring with a spring force, an actuator with an actuator force opposing the spring force, and a pin that is actuated by the actuator, a seal element that can be coupled with the pin, and a seal seat, the valve being closed when the seal element sits against the seal seat. The method includes determining an expected natural opening time when the seal element is lifted off the seal seat based on a pressure difference in front and behind the valve, impressing a specified current on the actuator at a point in time within a specified interval prior to the natural opening time, the seal element sitting against the seal seat at the point in time such that the pin contacts the seal element and the actuator force matches the spring force, which is reduced by a specified value.

摘要： An inlet valve arrangement for a pump head of a fuel pump for use in a common rail fuel injection system comprises an inlet valve member moveable between open and closed positions to control the flow from a source of low-pressure fuel to a pumping chamber of the fuel pump. The inlet valve member is arranged to open in response to the pressure difference between the fluid pressure of fuel on an inlet side of the inlet valve member and the fluid pressure in the pumping chamber exceeding a threshold value. The inlet valve arrangement comprises means for selectively applying a closing force on the inlet valve member to bias it toward the closed position, such that, in use, the application of the closing force by said means acts to increase the threshold value of the pressure difference at which the inlet valve member opens.

摘要： At least one choked flow passage communicates between one side of the movable member and the other side of the movable member and limits an amount of fuel, which passes from the one side of the movable member to the other side of the movable member, when the movable member is moved by an urging force of a relief spring toward a valve element. A larger amount of fuel, which is larger than the amount of fuel that is passable through the at least one choked flow passage, flows from a first return flow passage to a second return flow passage, when the movable member is moved toward the other side, which is opposite from the valve element, against the urging force of the relief spring.

摘要： An electronically actuatable valve assembly having a primary face seating valve, including a primary valve member, and a secondary valve, including a secondary valve member. The secondary valve opens before the primary valve to equilibrate pressure across the primary valve member and thereby facilitate opening of the primary valve member. The secondary valve is coupled to an armature which moves from a first position to a second position, in use, attracted by an electromagnet. The coupling between the armature and the secondary valve is configured to enable the armature to begin to move from the first position without movement of the secondary valve. The armature has therefore moved from the first position, closer to the electromagnet, when the secondary valve is opened by way of the forces exerted through the coupling between the armature and the secondary valve member, and so a greater force can be exerted to open the secondary valve than would be the case if the secondary valve member was fixedly coupled to the armature.
