摘要： An apparatus for controlling the lift of a valve member in a flow control valve comprises an end stop assembly having at least two pieces, a plunger with one end interposed between these pieces and biasing members that urge the pieces into contact with the plunger. The plunger is movable by an actuator to thereby move the pieces of the end stop assembly from a first position in which the pieces of the end stop assembly form a first surface for contacting the valve member to a second position in which the pieces form a second surface that comes into contact with the valve member when the valve member is lifted from its seated position, to thereby allow different discrete lifts of the valve member.

摘要： A needle type fuel injector has a needle control chamber at a pressure subject to a control valve in a control valve chamber which in an opening phase is lifted from its seat to expose the control valve chamber, connecting passages, and needle control chamber to a low pressure drain and in a closing phase is urged against the seat to isolate the control valve chamber, connecting passages, and needle control chamber from the drain. Resistance to the flow or displacement of fuel through the control valve seat is provided by a pressure regulating valve as the control valve rapidly closes against its seat, thereby reducing the rate of closure and thus the impact of the control valve on the seat.

摘要： A valve includes a housing that surrounds a fluid outlet, a valve element with a longitudinal axis, a valve seat body that surrounds a fluid inlet and which has a sealing seat such that the valve is closed when the valve element bears against the sealing seat and which is coupled to the housing. The valve element is movable relative to the valve seat body in a direction of the longitudinal axis to enable a fluid flow from the fluid inlet to the fluid outlet, the valve seat body surrounds a guide surface to which the valve element is coupled in order to guide the movement of the valve element, and the valve seat body is formed from a harder material than the housing.

摘要： A flow control system for a fuel injector for an internal combustion engine is provided and includes an inlet port, an outlet, a return port, a 2-way control valve including a control valve member, a shuttle valve and a main valve. The control valve includes a first seat, a first resilient arrangement configured to force the control valve member towards the seat so as to close the control valve, and a first abutment that limits the lift of the control valve member away from the first seat. The first seat of the control valve is slidably arranged in the shuttle control chamber. An end stop for the first seat is provided such that the pressure in a shuttle control chamber tends to move the first seat towards the end stop. The first seat, upon its mechanical contact with a valve member is able to transmit at least a part of the force of the resilient means onto a shuttle valve body in the opening direction of the shuttle valve.

摘要： A high-pressure fuel pump for an internal combustion engine is described. The high-pressure fuel pump includes an improved configuration that beneficially simplifies certain features of the high-pressure fuel pump. More specifically, the disclosure provides for an inlet check valve positioned along an inlet fuel circuit and an outlet fuel circuit of the high-pressure pump that provides a path for a low-pressure inlet fuel flow to and a path for a high-pressure output fuel flow from a pumping chamber of the fuel pump. Because of the configuration of the inlet check valve and the outlet check valve, the complexity of high-pressure fuel pump is beneficially reduced, decreasing the cost of components and assembly and improving the life and reliability of high-pressure fuel pump.

摘要： A fuel system includes a plurality of fuel injectors each defining a nozzle supply passage, a nozzle outlet and a low pressure space. The fuel system includes a plurality of mechanically actuated pressure intensifiers each including a tappet and being positioned partially within one of the fuel injectors, and a common rail fluidly connecting with each of the fuel injectors. Each of the fuel injectors further includes an injection pressure control mechanism having an injection pressure control valve. Each injection pressure control valve blocks the corresponding pressure intensifier from the common rail and fluidly connects the pressure intensifier with the low pressure space at a first position, and fluidly connects the pressure intensifier with the common rail and blocks the pressure intensifier from the low pressure space at a second position. Injecting fuel via operating the fuel system may include operating the fuel system in a low leakage mode where the pressure intensifier displaces fuel at a low pressure, between high pressure injections.

摘要： An intensifier quill for a fuel injector fluidly connects a fuel injector to a common rail. The intensifier quill selectively supplies fuel to the fuel injector at either an intensified pressure or un-intensified common rail pressure. Fuel supplied by the quill at both the intensified and un-intensified pressure passes through a quill body, which includes an actuation chamber, a control chamber and a pressurization chamber. Energizing an actuator of the quill allows fuel from the control chamber to flow to drain, increasing pressure inside the pressurization chamber and the fuel injector to intensified pressure. Upon energizing the actuator of the fuel injector, fuel injector injects fuel at the intensified pressure. When the quill's actuator is de-energized and the fuel injector's actuator is energized, fuel injector injects fuel at the un-intensified pressure.

摘要： Disclosed is a valve comprising a valve member (72) that is guided so as to be movable in the direction of the longitudinal axis (73) thereof, extends into a valve pressure chamber (77), and is provided with a sealing surface (81) on a face which runs perpendicular to the longitudinal axis (73) thereof inside the valve pressure chamber (77). Said sealing surface (81) of the valve member (72) cooperates with a valve seat (79) that runs perpendicular to the longitudinal axis (73) thereof so as to at least largely close an opening (78) which is surrounded by the valve seat (79) relative to the valve pressure chamber (77). A connection (64) to a low-pressure area lies immediately next to said opening (78). The inventive valve member (72) is also provided with a peg (83) which extends into the connection (64) and by means of which liquid that flows out of the valve pressure chamber (77) when the sealing surface (81) of the valve member (72) is lifted from the valve seat (79) is directed in such a way that said liquid applies at least nearly no resulting force onto the valve member (72) in the direction of the longitudinal axis (73) thereof.

摘要： The valve has a valve member (72) that is guided so that it is able to slide in the direction of its longitudinal axis (73), protrudes into a valve pressure chamber (77) and, in the valve pressure chamber (77), has a sealing surface (81) at an end extending transversely in relation to its longitudinal axis (73), with which sealing surface (81) the valve member (72) cooperates with a valve seat (79) extending transversely in relation to its longitudinal axis (73) in order, at least to a large extent, to close an opening (78) encompassed by the valve seat (79) in relation to the valve pressure chamber (77). The opening (78) is adjoined by a connection (64) leading to a low-pressure region. The valve member (72) has a pin (83) that protrudes into the connection (64) and, when the sealing surface (81) of the valve member (72) is lifted away from the valve seat (79), this pin (83) conveys fluid flowing out of the valve pressure chamber (77) in such a way that the outgoing fluid exerts at least approximately no resulting force on the valve member (72) in the direction of its longitudinal axis (73).
