Abstract

The pump has a drive shaft (1) driven by a free wheel mechanism (3). An oil part comprises a cam (5), lobes (6), a part of the drive shaft that supports the cam, a roller (7) with a shaft (8) and a rolling bearing (9) that is supported by a support part, and an upper part of a piston (10). The cam is supported on the piston by using the roller. The oil part is provided such that the cam, roller and the bearing and angle transmission parts are immersed in oil of the oil part. A lip joint provides sealing between the oil part and the shaft (1).
