摘要： The invention relates to a pressure valve for installation in a supply line between a pump work chamber of a fuel injection pump and an injection site in an internal combustion engine to be supplied thereby. A valve body is provided with a valve seat and has a through conduit in which a pressure valve closing member is guided. A check valve is disposed in a work chamber, wherein the check valve and the pressure valve closing member are movable relative to one another, in the through conduit. A restoring spring on the injection side causes the check valve to rest in the through bore and on the pump chamber side disposes the pressure valve closing member to the valve seat of the valve body.

摘要： A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.

摘要： A pressure control valve for installation in a supply line between a pump work chamber of a fuel injection pump and an injection point in the engine to be supplied. A valve body that has a first valve seat and an axial through conduit in which a pressure control valve closing member is guided. The pressure control valve closing member opens toward the injection point counter to the force of a first valve spring and has a sealing face that cooperates with the first valve seat, as well as with an axial through bore in the pressure control valve closing member. The bore can be closed by a back-flow valve that opens in the direction of the pump work chamber and has a second valve spring. For an optimal, unthrottled fuel flow through the pressure control valve, fuel conduits are respectively formed between the radially outer circumference faces of the first and second valve springs and the housing walls that encompass them, through which conduit the fuel flows in an unthrottled fashion.

摘要： The high-pressure pump has at least one pump element which has a pump plunger which is driven in a reciprocating motion and defines a pump working space into which fuel is drawn in from a fuel feed via an inlet valve during the suction stroke of the pump plunger and from which fuel is displaced into a high-pressure region via an outlet valve during the delivery stroke of the pump plunger. The inlet valve and/or the outlet valve has a valve member at least approximately in the shape of a ball which acts as a sealing surface with a valve seat arranged in a valve housing. The valve member, in its open state, is lifted with its sealing surface from the valve seat, a first cross section of flow is cleared between the valve member and the valve seat, and downstream of the first cross section of flow, a second cross section of flow is formed between the valve member and the valve housing. In the direction of flow between the first cross section of flow and the second cross section of flow, a third cross section of flow is formed between the valve member and the valve housing, said third cross section of flow being larger than the first cross section of flow and the second cross section of flow.

摘要： A high-pressure pump has at least one pump element including a pump piston defining a work chamber and driven at least indirectly by a drive shaft in a reciprocating motion, counter to the force of a restoring spring. The pump piston is braced on the drive shaft at least indirectly via a sleevelike tappet, and the restoring spring engages at least the pump piston. A support element in the tappet braces the pump piston toward the drive shaft and is braced at least indirectly on the drive shaft. The restoring spring, via a spring plate, engages the pump piston and the tappet. The spring plate is elastically deformable in the direction of motion of the pump piston in such a way that as a result of its elastic deformation, deviations in the position of its contact faces on the pump piston and on the tappet are compensated for.

摘要： In a fuel injection pump of the distributor type, a solenoid valve is provided in the distributor and the valve member of this solenoid valve is supported in an axial bore of the distributor and actuated by a magnet fixed to the housing in order to block the connection between a pump working space of the distributor-type injection pump and a relief space during an intended high-pressure injection phase. Inherent in its construction, a distributor of such a fuel injection pump has a certain axial play in its mounting and this has an effect on the actuating travel of the valve member in the distributor in relation to the fixed electromagnet. In order to avoid changes in the magnetic properties, which can arise due to this axial association, part of the magnetic circuit in the form of a magnet plate is displaceable together with the distributor, with the result that the position of an armature connected firmly to the valve member relative to this part of the magnet core, with which it forms the working air gap, does not change depending on the axial position of the distributor, and the magnetic properties of the solenoid valve are thus maintained irrespective of the axial position of the distributor.
