A high-pressure fuel system including a housing having first and second high-pressure bodies (), which contact one another at a contact face. A high-pressure chamber in the housing passes through the contact face, and at least intermittently a high fuel pressure is present in the chamber (). A wall part having a longitudinal axis surrounds the housing at least in the region of the contact face, so that a leak fuel chamber () is formed between the wall part and the housing which chamber is sealed off from the outside.

High-pressure fuel device

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.
