Title: PISTON PUMP WITH A PIPE SEGMENT AS A BUSHING
Abstract:
Disclosed is a piston pump designed mainly as a motor pump for an ABS-braking system in a vehicle. In order to simplify its manufacture, a bushing (14) is provided in the form of a self-clinch pipe segment, i.e. a sealed and fixed pipe segment, between, on the one hand, one fastening element (36) inserted in the bore (12) and, on the other hand, the bore itself. Apart from the bushing being easy to produce out of cheap bars, the invention also has the advantage that the bearing bush (4) is sealingly mounted in the bore (12), without the need of a sealing element such as a sealing ring to be used.
