The journal (46) and the bearing (42) comprise offset axes (C-C', D-D') relative to one another. A rider (50) is fitted on said drive shaft (40) to effect movement of the rider (50) along an eccentric rotational path. The rider (50) comprises a body (51) with an open-ended aperture (52), a load section (55) disposed around a first portion of the circumference of the aperture (52) and an idle section (58) disposed around a second portion of the circumference, and wherein the load section (55) of the rider (50) comprises at least one outwardly facing flat surface (56, 57) for cooperation with a tappet (35, 36). The drive shaft (40) comprises an enlarged rear bearing (42) with a reduced-depth section (45) at a bearing-journal junction, and the idle section (58) of the rider (50) comprises a reduced-width portion.
