Abstract:
1. A switchable support element for a valve train of an internal combustion engine, said support element comprising: a housing having a bore, an axially displaceable inner element comprising a head for mounting a finger lever in the bore, a coupling means extending from the inner element which can be brought partially into engagement with an entraining surface of the housing for achieving coupling, at an axially distant position, of the inner element relative to the housing, a lost motion spring means arranged for acting between the inner element and the housing, at least one vertical stop means that overlaps an annular groove between the inner element and the housing for defining a coupling position of said coupling means with coupling lash relative to said entraining surface, wherein the vertical stop means is at least one thin-walled ring comprising a slot, the ring is placed or slipped axially, slot ahead, onto an outer peripheral surface of the housing to extend parallel to a transverse plane of the support element, the housing comprises at least one aperture through which a corresponding inner peripheral segment of the ring extends, a longitudinal or annular groove extends in the outer peripheral surface of the inner element, into which longitudinal or annular groove the corresponding inner peripheral segment projects, and an underside of the inner peripheral segment comes to abut against a lower end of the said longitudinal or annular groove for defining the coupling position.
