    摘要: A fuel injection valve, particularly an injection valve for fuel injection equipment of internal combustion engines, having a pump piston that can be activated using a piezoelectric or magnetostrictive actuator for exerting a translatory pump motion. A spray-discharge nozzle with at least one spray-discharge opening is hydraulically connected via a fuel pressure line to the pump piston. The spray-discharge nozzle opens when the fuel pressure produced by the pump piston in the fuel pressure line exceeds a predetermined threshold. In the fuel pressure line, at least one non-return valve is arranged so that it opens in the direction towards the spray-discharge nozzle and closes in the opposite direction.

    摘要: A fuel injection pump of a distributor type for internal combustion engines including, a pump plunger guided within a pump cylinder, which forms a pump chamber and which is driven to perform reciprocating and rotating motion by a driving gear which is submerged in a lubricating oil bath. The pump plunger has a distribution hole which is in contact with the pump chamber and which sequentially links this chamber, during the compression stroke of the pump plunger, to injection jets. The fuel filling of the pump chamber takes place via a magnetically operated valve, which is open during the intake stroke and closed during the compression stroke of the pump plunger. For an enlargement of the filling cross-section during the intake stroke without an enlargement of the opening of the magnetically operated valve, a relief hole in the pump plunger is used which serves a force balancing during the compression stroke and which during the intake stroke links up with a filling hole which is connected with a membrane reservoir.

    摘要: An electrically controlled fuel injection pump for internal combustion engines, in particular for direct fuel injection in engines having externally supplied ignition contains a plurality of pump pistons driven by a single common cam. The pumping quantity of fuel is delivered by pumping pistons is controlled via a rotary slide valve to the injection nozzles at the injection sites of the engine, wherein the quantity control is effected by an electrically controlled valve. An axial conduit of the rotary slide which discharges into control bores or control grooves distributed over the circumference of the rotary slide and cooperates with the pump work chamber and the pressure lines to the injection sites and is adjoined by at least one further control bore or control groove which communicates with a pressure reservoir. By this means, a preinjection, separate from a main injection, is made possible at the top dead center charge change.

    摘要: To reduce the construction expense and the space required for a fuel injection pump for supplying a plurality of cylinders of an engine, in particular an internal combustion engine having externally supplied ignition, a fuel injection pump including a drive shaft with a single common cam drives a plurality of pump plungers. The supply quantity is controlled via a rotary slide and a subsequent common distributor delivers the fuel to the injection nozzles at the injection sites of the engine. The quantity of fuel injected is effected by an electrically controlled valve seated in a relief line that branches off downstream of the rotary slide, which by closure of the relief line determines the injection phase.
