摘要： The invention relates to a radial piston pump for high-pressure fuel supply in fuel injection systems of internal combustion engines, in particular in a common rail injection system. The piston pump has a drive shaft which is eccentrically supported in a pump housing and on which a ring is slidingly supported. The ring cooperates with a plurality of pistons, disposed radially relative to the drive shaft in a respective cylinder chamber. The pistons are movable radially back and forth in the respective cylinder chamber by rotation of the drive shaft. To increase the efficiency of the engine, the cylinder chambers are filled with less fuel when demand drops. In this so-called partial element filling, in which a plate is retained in contact with a polygonal ring, increased wear and damage are prevented. The wear is brought about by a guide device which prevents rotation of the ring about its own axis.

摘要： A high-pressure piston pump with a plurality of pump elements is connected on the intake side to a pump that pumps fuel at low pressure in a regulated quantity. Each pump element is preceded on the intake side by a first and a second check valve in series. The first check valve opens counter to spring force in the intake phase of the pump element and closes in the pumping phase. The second check valve opens counter to spring force and closes, reinforced by spring force, at pressures of the fuel supplied by the pump that are higher than the negative pressure generated in a cylinder chamber of the pump element. The second check valve takes on the metering of the fuel supplied to the pump element; the first check valve blocks off the cylinder chamber counter to the check valve in the pumping phase, whereby the piston pump serves to supply fuel at high pressure in fuel injection systems of internal combustion engines, especially in a common rail injection system.

摘要： A fuel injection apparatus for internal combustion engines, having a fuel injection pump inserted into the housing of the engine. A pump piston, which is driven axially back and forth in a cylinder bore, with one end face defines a pump work chamber from which a short injection line leads to an injection valve, and which can be made to communicate via a feed line with a fuel-filled low-pressure chamber. A magnetic valve disposed on the fuel injection pump controls the high-pressure feeding into the injection line. In order to avert an overly rapid return flow of fluid from the injection line into the pump work chamber, a return flow throttle valve is inserted into the injection line.

摘要： A fuel-injection pump for internal combustion engines, particularly an in-line injection pump for diesel engine, with a control bore in the pump cylinder and with an upper control edge for determining the start of feed and an oblique spill edge for determining the end of feed. The pump piston is rotated about its longitudinal axis in order to set the desired feed quantity, for the purpose of achieving a better regulating behavior of the system as a whole, comprising the fuel-injection pump, feed-quantity regulator and internal-combustion engine. The spill edge is subdivided, along its run over a part of the circumference of the pump piston, into portions with different angles of inclination (.alpha..sub.1, .alpha..sub.2) to the axis of the pump piston. The control-edge portion having the large angle of inclination (.alpha..sub.2) is located in the region of the pump piston which passes over the control bore during the pump-piston stroke in a rotary position of the pump piston for small feed quantities (lowered load range of the internal-combustion).

摘要： A fuel injection pump for internal combustion engines, having a pump piston that reciprocates in a cylinder liner inserted into a pump housing. The pump piston and housing encloses a pump work chamber, and the pump piston has a control recess on its jacket face that communicates with the pump work chamber through a conduit. An oblique groove extends at a predetermined angle from the axis of the pump piston in the jacket face thereof and forms control edges. An annular slide is axially displaceable on the pump piston and includes two diametrically opposed diversion bores. To interrupt the high-pressure pumping to provide a pre-injection quantity and a main-injection quantity, first, second and third pockets are additionally machined into the jacket face of the pump piston. These pockets cooperated with pockets machined in the annular slide and with the control edge formed by the lower face edge of the annular slide to control the fuel flow.

摘要： A radial piston pump for a high-pressure fuel supply in fuel injection systems of internal combustion engines includes a drive shaft, supported in a pump housing, and a plurality of pistons disposed radially with respect to the drive shaft in respective cylinder chambers. The pistons are movable back and forth in the radial direction, and for each piston, one metal insert part forming the respective cylinder chamber is provided inside the housing and radially to the drive shaft to communicate with the intake side and with the high-pressure side. The respective insert part in the direction of the drive shaft between two flangelike metal housing parts with bearing faces extend perpendicular to the drive shaft and rests on these faces. The respective insert part has a fuel delivery opening and a fuel discharge opening, which discharges in the region of the bearing faces and are aligned with a further respective delivery and discharge opening in the housing parts. The flangelike housing parts are tightened against one another, with the interposition of the insert parts, in such a way that the bearing faces of the respective insert part and housing parts effect high-pressure sealing with the interposition of sealing elements.
