Such a radial piston pump is shown in FIG. 3 and 4 of the German patent 1 096 750 known to the applicant

In the utility model 1 997 600 the registrar was already proposed to simplify the construction that the ring part at the same time a sealing on the base plate open pump gap forms instead of as before Separate components for the ring part and the pump housing ekapp e to be provided. It was also proposed that the ring part, which also forms the pump engehaus ekapp e, is made of die-cast to manufacture. Furthermore, according to the older proposal, the housing cap forming the ring part can open without centering be clamped on the base plate.

The older proposal was based on the knowledge that that you can significantly improve the construction of a radial piston pump of the type mentioned if you have a single Component in addition to the clamping function in relation to the cylinder blocks and the holding function for a bearing of the eccentric shaft! still assigns the additional function as part of the pump housing.
