Abstract
In a switching element ( ) for a valve train of an internal combustion engine for switching to different valve lifts, said switching element ( ) comprising an outer element ( ) having an inner element ( ) arranged for axial displacement therein, each of the outer and the inner element ( ) comprising a reception ( ) aligned to each other in a relative position, at least one piston ( ) being arranged in at least one of the receptions ( ) for sliding toward the other of the receptions ( ) to couple the inner element ( ) to the outer element ( ) in said relative position, and a high-position stop for defining said relative position being arranged between the inner and the outer element ( ), at least one part of the high-position stop is configured as an adjustable, separate element ( ). This element ( ) cooperates through a preferably conical section ( ) of its outer periphery with a complementary chamfer ( ) on one end ( ) of a guide ( ) in the outer element ( ). By these extremely simple fabrication measures, an aligned adjustment of the receptions ( ) is created for effecting coupling.
