摘要： A fuel pump includes a housing having therein a suction passage and a pressurization chamber into which fuel from the suction passage flows, a plunger held in the housing to be reciprocable so as to pressurize the fuel flowing into the pressurization chamber, and a diaphragm device located in a suction chamber that is provided in the suction passage. The diaphragm device includes a pair of first and second diaphragms that are arranged to define an inner space therebetween and air-tightly sealed at its entire peripheries. A mass addition member may be attached to an inside surface of at least one of the first and second diaphragms, so that the first and second diaphragms with the mass addition member have different characteristic frequencies. Accordingly, pressure pulsation of the fuel in the suction chamber can be effectively reduced by the pulsation damper.

摘要： A high pressure pump draws fluid from a fluid inlet into a compression chamber through an inlet chamber. The high pressure pump has a fluid chamber that communicates with the fluid inlet via the inlet chamber. The high pressure pump includes a plunger and a cylinder. The plunger draws fluid from the inlet chamber into the compression chamber when the plunger moves in a drawing direction. The plunger is capable of pressurizing fluid in the compression chamber when the plunger moves in a pressurizing direction. The cylinder movably supports the plunger therein. When the plunger moves in the drawing direction, fluid in the inlet chamber is drawn into the compression chamber, so that fluid flows from the fluid chamber into the inlet chamber.

摘要： A purpose of the present invention is to provide a fuel delivery pipe having a flexible absorb wall surface formed on a wall surface thereof in which a fuel introduction pipe is connected to an interior of the fuel delivery pipe body at one end thereof in a longitudinal direction in order to achieve a suppression of a transfer of a first mode of a standing wave and a second mode of the standing wave and an enhanced placement layout and inexpensive cost.The fuel delivery pipe includes the flexible absorb wall surface formed on the wall surface thereof and injection nozzles, in which fuel introduction pipe 10 is connected to one end of fuel delivery pipe body 1 of a returnless type without a circuit returning to a fuel tank and is coupled with the fuel tank through an underfloor pipe arrangement. In the fuel delivery pipe, provided that an entire length of an interior of fuel delivery pipe body 1 in the longitudinal direction is 100, fuel introduction pipe 10 is inserted into fuel delivery pipe body 1 up to a position between 15 and 35 or a position between 65 and 85 with regard to the entire length and then securely connected to fuel delivery pipe body 1.

摘要： The invention relates to an intermediate plate for a fuel injector, comprising a high-pressure through-hole which connects a high-pressure passage in a valve body and is connected to a high-pressure fuel reservoir, to a high-pressure space in a nozzle body, wherein the intermediate plate is arranged between the valve body and the nozzle body. In order to improve the injection behaviour of a fuel injector provided with the intermediate plate, in particular during multiple injection of small injection quantities, the high-pressure through-hole has a cross-sectional profile which improves the flow through the high-pressure through-hole from the valve body towards the nozzle body and impairs the flow in the opposite direction from the nozzle body towards the valve body.

摘要： A bush incorporated in a common rail is formed with a smallest diameter orifice having a small inner diameter and an adjacent orifice having an inner diameter larger than that of the smallest diameter orifice on an inner peripheral face of the bush. A press-fitted portion, which is press-fitted into an inside-outside communication hole, and a non-press-fitted portion, which has a smaller outer diameter than the press-fitted portion, are formed on an outer peripheral face of the bush. The smallest diameter orifice and the press-fitted portion are deviated from each other in an axial direction of the bush to prevent an overlap in a radial direction of the bush. Thus, even if the bush is tightly press-fitted into the inside-outside communication hole, decrease of the inner diameter of the smallest diameter orifice can be averted.

摘要： A diaphragm assembly for use with a hydraulic apparatus. The diaphragm assembly includes a cap formed of a rigid material and a diaphragm formed of an elastomeric material. The diaphragm is generally tubular and includes an upper annular collar portion defining an open upper end of the diaphragm and a main body portion extending downwardly from the collar portion, defining a closed lower end of the diaphragm, and including, in cross-section, a plurality of hollow radially extending circumferentially spaced arms. The cap includes an upper disc portion sized to receive the collar portion of the diaphragm and a rib portion extending downwardly from the disc portion and including, in cross-section, a plurality of radially extending circumferentially spaced arms positioned respectively within the arms of the main body portion of the diaphragm whereby the elastomeric arms of the diaphragm provide large expansion and contraction capacity and the rigid arms of the cap preclude undesired distortion or wrinkling of the flexible arms of the diaphragm.

摘要： The invention relates to a device for damping pressure surges in a fluid with a housing (10) and a piston (14) that can be longitudinally displaced inside the housing (10) against the pretensioning force of a spring energy store (12). In order that the piston (14) interacts with another piston (24), which is guided in a connecting piece (26) of the housing (10) in a manner that enables it to be longitudinally displaced, and that, during the operation of the device, the piston (14) exerts a pressure force onto the other piston (24) when the latter is in any displacement position, even pressure surges occurring with a high frequency can be reliably controlled in a functionally reliable manner.
