摘要： A component for an injection system. The component includes a base body and at least one connecting piece, which is formed at the base body and used to connect an injector. The injector, during assembly, being insertable along a mounting axis into an accommodating space of the connecting piece. The base body and the connecting piece are formed by a forging operation. A recess is formed at an outer side of the connecting piece, in which, in the mounted state, an orienting element of the injector engages for restricting a rotational degree of freedom of the injector about the mounting axis. The connecting piece is post-processed after the forging so that a lateral surface of the recess is at least approximately configured with a predefined lateral height.

摘要： A tappet assembly for use in translating force between a camshaft lobe and a fuel pump assembly via reciprocal movement within a tappet cylinder having a guide slot. The tappet assembly includes a bearing assembly having a shaft and a bearing rotatably supported by the shaft for engaging the lobe. An intermediate element has a shelf for engaging the fuel pump assembly, and a pair of arc-shaped bearing surfaces rotatably engaging the shaft when the bearing engages the lobe and the shelf engages the fuel pump assembly. The intermediate element includes a pair of lock apertures. The bearing assembly further includes a pair of shields supported on the shaft of the bearing assembly with the bearing interposed between the shields. The shields include a pair of opposing fingers for engaging the lock apertures so as to substantially retain the bearing assembly to the intermediate element and so as to substantially retain the shaft of the bearing assembly within the annular body in absence of engagement between the bearing and the camshaft lobe.

摘要： A distal end portion of an injector is fitted into a mounting member. A fuel joint having a connecting pipe portion is connected to a proximal portion of the injector. A joint pressing member which restricts the displacement of the fuel joint in the direction away from the mounting member is fixed by fastening to the mounting member. The injector is fixed to the mounting member by restricting the displacement of the fuel joint by the joint pressing member.

摘要： A fuel rail assembly for gasoline direct injection fuel delivery to an engine. The assembly has a common rail tube. In the tube there are threaded orifices extending laterally. Injector sockets are adapted to mate with the threaded orifices. Each injector socket has a proximal nipple end region connected to the tube and a distal end region through which fuel is delivered to the engine. Screw threads are disposed around the proximal nipple end region. The screw threads include a lead thread that is received by the threaded orifices, thereby forming mechanical connections between the injector sockets and the tube that are adapted to withstand maximum pressures of fuel up tp 2900 psi.

摘要： The invention relates to an anti-rotation device of a fuel lance arranged in a bore extending through a cylinder head of a cylinder head from an intake opening until a hole provided for receiving a fuel injector, the lance allowing high-pressure fuel to circulate from an intake opening of the lance until the outlet opening of the lance engaging with the intake opening of the fuel injector, the fuel lance including a nut for being screwed into the intake opening of the bore and a tubular member compressed between the nut and the injector, the lance also including the anti-rotation device. The anti-rotation device is a resilient element which is deformed by rotation of the nut, such as to be blocked between the tubular member and an inner wall of the bore, and thus prevent rotation of the tubular member when the nut is screwed.

摘要： A fuel injector with an anti-rotation clip for use in conjunction with a twist lock fuel injector inserted into a receiving fuel cup. The clip includes at least one connector leg which extends at least partially over the electrical connector for the fuel injector and locks the clip against rotation relative to the fuel injector electrical connector. A protrusion on a fuel cup arm engages a notch formed in the fuel cup to lock the arm against rotation relative to the fuel cup.

摘要： A fuel injector assembly has a control valve body and a plurality of end caps. End cap locating holes are formed into a mating surface of each end cap, and control valve body locating holes are formed into each mating surface of the control valve body. Locating pins inserted into the end cap and control valve body locating holes each have a fixed portion that affixes the locating pins to either the control valve body or the end cap. In the event of failure of a locating pin between the fixed portion and a free portion of the pins, the free portion maintains alignment of the control valve body locating holes with the end cap locating holes.

摘要： A covering body (10) made of a synthetic resin and including a rear shoulder part (16) oriented toward a fuel inlet part (6) side is formed around an outer periphery of an intermediate portion in an axial direction of a fuel injection valve (I). The rear shoulder part (16) includes: a first semicircular shoulder part (16a) extending over a half periphery of the covering body (10); a second semicircular shoulder part (16b) shifted in the axial direction with respect to the first semicircular shoulder part (16a) and extending over the other half periphery of the covering body (10); and a standing wall (16c) standing to connect the first and second semicircular shoulder parts (16a, 16b). On a front end of a fuel supply cap (20), a semicircular holding surface (28b) holding at least one of the first and second semicircular shoulder parts (16a, 16b) to prevent the fuel injection valve (I) from being fallen off from the mounting hole (2), and a rotation stopper surface (28c) abutting against the standing wall (16c) to prevent rotation of the fuel injection valve (I) are formed. Accordingly, it is possible to provide a fuel injection valve mounting structure including positioning means capable of firmly restricting an orientation of a coupler in a given direction without forming projections on a fuel injection valve and a fuel supply cap.
