摘要： Described is a fuel injection device, in particular a pump injector, for injecting fuel into internal combustion engines and in which the start and end of fuel delivery is controlled by a solenoid valve (5) fitted between a low-pressure line and the working space (9) of the pump piston (10; 17). The device has a flush bore (12) which can be connected to the working space (9), the flush bore being connected to a low-pressure space and the fuel tank. A feed bore (7) in the feed line (6, 7) from the solenoid valve (5) intersects the cylinder bore (11) for the piston (10; 17). Instead of using a dedicated bore as the flush bore (12), the part of the feed bore (7) is used which lies behind the point of intersection with the cylinder bore (11) for the piston (10; 17), and is derived from the solenoid valve (5).

摘要： Pump injector (10) comprising an injection nozzle (14) mounted at least approximately at right angle with respect to the longitudinal axis (A) on the pump housing (11) of the piston injection pump (12). The injection pump (12) bears with a bearing face (24b) forming the axial end projection thereof on a support bearing (25) provided at the cylinder head (18) of the internal combustion engine. The bearing surface (24b) is formed of a front face directed to the outside, of an opposite piston (24) introduced in the prolongation of the longitudinal axis (A) of the pump piston in the pump cylinder (21) and sealingly closing the pump working chamber (15) by means of an inner front surface (24a). The pump forces on the pressurized fuel in the pump working chamber (15) are thereby taken away from the pump housing (11) and received at the cylinder head at a location remote from a supply inlet (17) for the fuel injection nozzle (14).
