Definitions
- plungers are cylindrical multipart or rectangular multipart design. One part serves for the axial bearing of the roller, the so-called roller shoe. A second part serves to mount the plunger in the pump housing. The two parts are pressed together, for example.
- the plunger 101 tapers in connection with the outer surface 105, as shown in Figure 1A, so that the Snap ring 108 in the coupled state does not project beyond the outer surface 104.
- Snap ring 108 has first and second end portions 111 and 112.
- the snap ring 108 has a shape such that the end regions 111 and 112 are respectively coupled to one of the surfaces 109 and 110 in the coupled state.
- In the coupled state of the snap ring 108 surrounds the plunger 101 partially, at least by 180 ° with respect to a cross section of the plunger 101 and the groove 118 and less than 360 °.
- the coupling of the snap ring 108 with the roller 102 takes place at the two end regions 111 and 112.
- the recess 119 can be dispensed with.
