Abstract: A valve for controlling fluids, having a valve housing which has an actuator chamber and at least two laterally located inlet bores that communicates with a high-pressure inlet, and the actuator chamber has an actuator with a ram and an actuator cap, and the actuator chamber has a conical seal, which is embodied by means of a conical face on the end of the actuator chamber and a corresponding annular sealing face on the actuator cap, and with the conical seal a cable outlet can be sealed off. A more-uniform introduction of force to the actuator is attained by the plurality of inlet bores.

Abstract: 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.

Abstract: A radial piston pump for supplying high fuel pressure in fuel injection systems of internal combustion engines that include a common rail. Pistons, which are disposed in a respective cylinder chamber, each of the pistons have a plate connected to one end. A center of each of the plates is embodied so that the stresses that occur in this location during operation are reduced. Reducing the stresses in each plate center advantageously extends the service life of each of the plates. A perfect function of the plate is thus assured, even at peak pressures of up to 2000 bar.

Abstract: A radial piston pump for generating high fuel pressure in fuel injection systems of internal combustion engines, having a drive shaft which is supported in a pump housing. The drive shaft is embodied eccentrically or has camlike protrusions in the circumferential direction. A plurality of pistons are disposed radially with respect to the drive shaft in a respective cylinder chamber. A plate is mounted on the ends of each piston toward the drive shaft, and the pistons are movable back and forth radially in the respective cylinder chamber by rotation of the drive shaft. Wear problems are solved by providing that the plate is pivotably connected to the associated piston. By the deflection of the plate on the piston, the load on the piston from moments of the bracing force is lessened.
