Abstract:
A switchable cam follower of a valve train of an internal combustion engine, whereinthe cam follower comprises a housing adapted to be mounted with an outer wall in a bore of the internal combustion engine or in a bore of a component connected to the internal combustion engine,the housing comprises a recess which encloses an inner element that is axially displaceable relative to the housing, each of said housing and said inner element comprising a reception extending in radial direction, said receptions being aligned to each other in a defined relative position,at least one coupling means is arranged in at least one of the receptions and said coupling means can be displaced toward the other of the receptions for coupling the inner element to the housing in said relative position,a stop means extends between the housing and the inner element and prevents a rotation of the inner element relative to the housing while also forming an upper end stop for defining the relative position,a locking element is arranged as a first component of the stop means in the reception of the inner element, an inner jacket section of the locking element extending over at least a substantial part of half a length of the reception of the inner element, an outer jacket section of the locking element forming a second component of the locking element and engaging into a slot of the housing,the slot fixes the locking element in peripheral direction of the housing and has an axial dimension corresponding to at least a length of a desired relative displacement, one end of the slot forming the upper end stop, and the outer jacket section of the locking element extending at least through a largest possible dimension of the slot toward an outer peripheral surface of the housing.
