摘要： A fuel injection apparatus has a high-pressure pump and a fuel-supply pump that delivers fuel from a fuel tank to the high-pressure pump. The high-pressure pump has a housing with an internal chamber that contains a drive unit for at least one pump element having a pump piston driven by the drive unit and delimiting a pump working chamber into which fuel is supplied via an inlet during an intake stroke and from which fuel is displaced via an outlet into the reservoir during a delivery stroke of the pump piston. The fuel-supply pump delivers fuel into the internal chamber via a connection that contains a check valve which opens toward the internal chamber of the housing and the inlet of the pump working chamber is connected to the internal chamber.

摘要： A stroke-controlled valve as a fuel metering device of an injection system for internal combustion engines has a valve body with a valve seat and a valve needle which is actuatable in the valve body counter to the resistance of a valve needle restoring spring and which has a sealing edge that cooperates with the valve seat. A coupling body with a greater mass than the valve needle is disposed in the valve body, in the axial extension of the valve needle, and is movable coaxially to the valve needle and is actuatable by the valve needle during the opening stroke of the valve needle.

摘要： The fuel injection device has a fuel injection valve that has an injection valve member, which is guided so that it can slide in a valve body and controls at least one injection opening and which can be moved in the opening direction, counter to the force of a closing spring contained in a spring chamber by means of the pressure prevailing in a pressure chamber of the fuel injection valve. Highly pressurized fuel is supplied from a high pressure source to the pressure chamber of the fuel injection valve. An electrically controlled valve at least indirectly controls a connection of the pressure chamber to a relief chamber and connects the pressure chamber to the relief chamber in order to terminate the fuel injection. The pressure chamber of the fuel injection valve has a connection to the spring chamber, which connection contains a check valve that opens toward the pressure chamber.

摘要： A geared pump, having a housing (18), two gear wheels (14, 16) that are disposed in the housing and mesh with one another, and at least one groove (22) that is embodied in the housing on the pressure side of the geared pump, cavitation damage at high rpm is to be avoided. To that end, it is provided that the groove has a first portion (24), which extends from the pressure side, and in which the bottom of the groove (22) has a slight spacing from the tips of the teeth (20) of the gear wheel, and a second portion (26), which adjoins the first portion and in which the bottom of the groove (22) has a maximum spacing from the tooth tips that is greater than the spacing in the first portion, and the first portion extends over a smaller angular range (&agr;) than the second portion, and the groove extends over a total angular range (&agr;, &bgr;) that is somewhat greater than angular spacing between two teeth (20).
