摘要： The valve having a valve member guided displaceably in the direction of its longitudinal axis protrudes into a valve pressure chamber and has a sealing face extending transversely to axis, has a sealing face, which it cooperates with a valve seat, extending transversely to axis, for at least extensively closing off an opening, surrounded by the valve seat, from the valve pressure chamber. The sealing face is surrounded by an annular face, which when the valve member rests on the valve seat is disposed at a slight spacing from the valve seat. The valve member has a plurality of apertures, distributed over its circumference, through which the opening communicates with the valve pressure chamber when the valve member is resting on the valve seat.

摘要： A fuel injection pump designed to deliver an amount of fuel divided into a pilot and a main injection volume, including a surface of a pump plunger which is guided within a pump cylinder, apart from two recesses limited by an inclined control edge, a first horizontal control edge is formed by a frontal shoulder; and on a side opposite the shoulder, it has a fully enclosed transverse groove with a second and third control edge. Two control apertures and an annular groove above them in the wall of the pump cylinder effect the control, in conjunction with the aforementioned control edges, of the precisely determinable pilot injection and, after a delivery interval, determined by the difference (b-a) between the width (b) of the transverse groove and the distance of the annular groove to the control aperture, the subsequent main injection. For the purpose of controlling an exact and largely speed-independent start of delivery of both the pilot and the main injection, the control apertures can be equipped with a straight limiting edge on the pump chamber side.

摘要： In an apparatus for generating pre-injection quantities in unit fuel injectors for Diesel engines, including a pre-injection slide that generates a pronounced pressure intensification for a pre-injection in a pressure chamber closed off with respect to the high-pressure side and opens towards the injection line is slidably supported in a guide bore. The pre-injection slide is exposed to the injection pressure of an element chamber in such a way that after the execution of a partial stroke, which is responsible for the pre-injection quantity, upon further movement the pre-injection pressure chamber is opened toward the element chamber and thereby relieved, and by the ensuing movement of the pre-injection slide until the end of the stroke, a pre-determinable capacity that enables an injection pause is formed. A valve which is supported inside the pre-injection slide is under the control of a magnetic valve associated with the unit fuel injector and provides for the filling of the pre-injection pressure chamber forms selectively actuatable shutoff control for the pre-injection.

摘要： A fuel injection system with a fuel injection valve and a control valve, which control valve has a control valve member that can move longitudinally in a control valve bore. The control valve member is provided with a control valve sealing surface, which cooperates with a control valve seat and thereby controls the connection between a first pressure chamber and a second pressure chamber, where the first pressure chamber is connected to a high-pressure accumulation chamber. A bore is embodied in a valve body and contains a piston-shaped valve needle whose end oriented toward the combustion chamber controls the opening of at least one injection opening by virtue of the fact that it executes a longitudinal movement due to the impingement of the pressure in a pressure chamber; the pressure chamber is connected to the second pressure chamber by means of a supply conduit. The first pressure chamber is connected by means of a throttle to a damping chamber that is otherwise closed, as a result of which, pressure oscillations that are produced by the closing of the control valve are rapidly damped.

摘要： A fuel injection valve includes a housing in which a pistonlike valve member is disposed longitudinally displaceably in a bore to cause at least one injection opening to communicate with a pressure chamber embodied in the housing. An inlet conduit discharges into the pressure chamber to fill the pressure chamber with fuel at high pressure. A fuel-filled control chamber in the housing at least indirectly exerts a force acting in the closing direction on the valve member. The control chamber communicates with the inlet conduit and can be made to communicate via a control valve with a leak fuel chamber. A damping chamber communicates with the inlet conduit via a throttle.

摘要： A fuel injection device for internal combustion engines with a high pressure fuel pump that delivers fuel from a low pressure chamber via high pressure lines to at least one injection valve that protrudes into the combustion chamber of the engine to be fed. The device includes a through flow limiting valve that defines a maximum fuel flow quantity in one or a number of high pressure lines and has a valve member, which can move axially and in its closed position, can be brought against a valve seat counter to the force of a restoring spring by fuel flowing toward the injection valve when a maximum fuel flow quantity is exceeded. Wherein the fuel flow through the valve member that is lifted up from its seat can be adjusted in at least one throttle location in the valve member. In order to be able to detect even extremely small leakage quantities, the through flow limiting valve is designed so that in each injection, the valve member executes a stroke motion toward the valve seat but only reaches it when there is a leaky high pressure line, wherein when there are low leakage quantities, the initial position of the valve member moves toward the valve seat during the injection pauses.

摘要： A fuel injection pump for internal combustion engines is proposed, in which to attain particularly quiet operation of an engine that is operated with direct injection, the fuel delivery is subdivided into a preinjection and a main injection; this injection is attained by annular groove, coinciding with one another, on the pump piston and pump cylinder, and a connecting groove connecting the coinciding annular grooves with a relief opening. After a partial stroke in the region of coincidence of the annular grooves with one another, the communication with the relief opening is interrupted again. The preinjection quantity can be kept particularly small here, with a short interval between the preinjection and the main injection; in combination with a two-spring-holder injection valve, this particularly small preinjection quantity can be kept constant to a great extent even at varying engine speeds, to attain an optimal reduction in combustion noise at various engine speeds.

摘要： A fuel injection apparatus which the termination of the effective pump supply stroke is effected by exposing a relief conduit with the aid of a valve having for instance a control edge, whereupon a highly pressurized fuel flows out via the relief conduit and is directed into a pressure chamber defined by a rear face of a pressure valve closing member. The pressure valve closing member is located in a connection with a fuel injection line that leads from the pump work chamber to the fuel injection valve and is acted upon by a valve spring to effect closing of this injection line. The impact of fuel that reaches the pressure chamber via the releif conduit reinforces a fast closure of the pressure valve closing member at the end of injection, which leads to an abrupt termination of an injection cycle. In addition, or altenatively, the fuel injection valve closing member can also be acted upon by the impact of fuel diversion.
