摘要： A fuel pump includes a pump housing with a pumping chamber an inlet valve bore. An inlet valve selectively provides and prevents fluid communication between an inlet of the fuel pump and the pumping chamber. The inlet valve includes an inner housing received within the inlet valve bore such that an outer periphery of the inner housing is sealed to an inner periphery of the inlet valve bore. An outer housing circumferentially surrounds the inner housing. An annular chamber is defined radially between the inner housing and the outer housing and axially between the outer housing and the pump housing. A sealing ring is located within the annular chamber such that the sealing ring is compressed axially against the pump housing and the outer housing.

摘要： In an electromagnetically controlled inlet valve actuator provided to a high pressure fuel pump, an impinging sound which is generated at the time of operating the mechanism is reduced. In a high pressure fuel pump provided with an electromagnetically controlled inlet valve (operated by way of a plunger rod), a current supply period includes a 1st current supply period for performing an operation of attracting the plunger rod in a valve closing direction, a 2nd current supply period for alleviating a speed at which the plunger rod moves in a valve opening direction, and a limited current supply period disposed between the 1st current supply period and the 2nd current supply period in the form of spanning a pump top dead center.

摘要： A shutoff valve (2) which is switchable in a cycled manner for capacity regulation by temporarily shutting off the intake gas feed is designed as a multi-element ring valve, and is directly actuated by means of an electromagnet (12). The actuating forces for switching the shutoff valve (2) may be kept small via pressure compensation from the intake gas feed (3) to behind the anchor plate (9).

摘要： A high-pressure fuel pump for an internal combustion engine. The high-pressure fuel pump includes an improved configuration that beneficially simplifies certain features of the high-pressure fuel pump. The fuel pump possesses 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 fluid-working machine has a plurality of working chambers, e.g., cylinders, of cyclically changing volume, a high-pressure fluid manifold and a low-pressure fluid manifold, at least one valve linking each working chamber to each manifold, and electronic sequencing means for operating said valves in timed relationship with the changing volume of each chamber, wherein the electronic sequencing means is arranged to operate the valves of each chamber in one of an idling mode, a partial mode in which only part of the usable volume of the chamber is used, and a full mode in which all of the usable volume of the chamber is used, and the electronic sequencing means is arranged to select the mode of each chamber on successive cycles so as to infinitely vary the time averaged effective flow rate of fluid through the machine.

摘要： To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump. In the present invention, in order to achieve the above object, the mass of a member which collides by magnetic attractive force is reduced to reduce the noise to be generated. The thus configured present invention provides the following advantageous effects. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced.

摘要： In open-circuit hydraulic systems (1), the cross-sections of the supply lines (6) and input valves of the hydraulic pump (3) have to be large, so that sufficient flow flux can be provided. This hinders a reduction of the size of the pump and the whole hydraulic system. It is suggested that the supply flow (7) of a hydraulic pump (3) is charged by a second, charging pump (2), to a mid-pressure level (7). The cross-sections of the supply flow areas can thus be decreased.

摘要： A method for operating a fuel pump is provided. The method may include decreasing a pump chamber pressure, passively opening a metering valve coupled to a pump chamber in response to the decreasing, and while the metering valve is open, generating a rotational output via a motor, transferring the rotational output into an actuation force applied to the metering valve via a metering valve actuation device, and inhibiting the metering valve from closing via sustaining application of the actuation force.
