RADIAL PISTON PUMP WITH A CLOSED ONE-SIDED BEARING SHELL

摘要

The invention concerns a radial piston pump with at least one working piston, which is placed at the cylinder block on the housing (5) and which is driven by a shaft (3) projecting into the cylinder block (3). A radial bearing (1) is placed on the eccentric part (2) of the shaft, and the end of the piston, which projects radially from the cylinder block inwards, can be pressed by the bearing shell (7) of said radial bearing. According to the invention, the bearing shell (7) is closed at the side associated to the end of the eccentric part (2).
