ABSTRACT:
The invention proposes a push-rod valve train having an adjustable valve tappet (1). This has an outer part (2a, 2b), an inner part (8) and a lost-motion spring (10), which forces the inner part (8) towards a relative position, at least one retainer ring (23), which is fixed in an annular groove (21) of the outer part (2a, 2b) and which interacts with a stop face (22) of the inner part (8), being provided for fixing the relative position, said retainer ring having lugs (28) extending radially inwards and separated by a fitting gap (27). In this the free movement of the valve push rod (15) relative to the lugs (28) is assured by the provision of a torsional locking means (30a, 30b), which serves to fix the radial position of the fitting gap (27) inside the annular groove (21).
