摘要： The fuel injection system having one high-pressure fuel pump and one fuel injection valve for each engine cylinder in which the pump piston defines a work chamber, which communicates with a pressure chamber of the fuel injection valve. A control valve controls connection of the pump work chamber with a relief chamber and having a second control valve controls a connection of a control pressure chamber, which communicates with the pump work chamber defined by a control piston with a relief chamber is controlled, and in which connection a throttle restriction is provided. A flow cross section of the connection of the control pressure chamber with the relief chamber is controlled as a function of the stroke of the control piston, such that with an increasing opening stroke of the injection valve member, a smaller flow cross section is uncovered by the control piston and at the maximum opening stroke of the injection valve member, the uncovered flow cross section is smaller than the flow cross section of the second throttle restriction.

摘要： A fuel injection valve for internal combustion engines, having a housing (1) in which a pistonlike outer valve needle (10) is disposed longitudinally displaceably in a bore (3) and cooperates with a valve seat (13), embodied on the end of the bore (3) toward the combustion chamber, to control at least one injection opening (7). A control chamber (24) is embodied in the housing (1), the pressure in the control chamber (24) being regulatable by a valve (33), and by the pressure in the control chamber (24) a closing force is exerted at least indirectly on the outer valve needle (10) in the direction of the valve seat (13). At least one pressure face (9; 101) is embodied on the outer valve needle (10) and is acted upon by the pressure in a pressure chamber (5), which is embodied between the outer valve needle (10) and the wall of the bore (3) and extends as far as the valve seat (13), so that an opening force on the outer valve needle (10) results that is oriented counter to the closing force. An inner valve needle (12) is guided in the outer valve needle (10) and controls at least one additional injection opening (7) on the valve seat (13) and is acted upon by the pressure in the control chamber (24) at least indirectly in the direction of the valve seat (13) (FIG. 1).

摘要： A solenoid-valve-controlled fuel-injection pump for internal combustion engines, in particular diesel engines, has a solenoid valve, whose valve needle separates a high-pressure region from a low-pressure region, i.e. connects the high-pressure region and low-pressure region, in the pump housing, via a valve seat; the injection period being controlled by the opening of the solenoid valve. In addition, a low-pressure compensating piston situated in the low-pressure region is provided in order to compensate for pressure fluctuations in the low-pressure region. The exceptional feature is that the low-pressure compensating piston, which is positioned coaxially to the solenoid-valve needle, takes the form of a component part that is separate from the solenoid-valve needle. This ensures that the solenoid valve is opened unhindered and as rapidly as possible by the opening force exerted on the solenoid-valve needle by the electromagnet.

摘要： A high-pressure pump (1), which serves in particular as a radial or inline piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprises a cylinder head (2) and a pump assembly (6). Here, the cylinder head (2) has a cylinder bore (4) in which a pump piston (5) of the pump assembly (6) is guided. Here, the pump piston (5) delimits, in the cylinder bore (4), a pump working chamber (12). Also provided is an inlet valve (20) which is integrated into the cylinder head (2) and via which fuel can be conducted into the pump working chamber (12). Metering of the fuel conducted into the pump working chamber (12) can be achieved by actuation of the inlet valve (20). Here, full charging of the pump working chamber (12) may take place. It is however also possible for partial charging of the pump working chamber (12) to be achieved by means of suitable actuation of the inlet valve (20).
