ABSTRACT:
A hydraulic play compensating element (1) for a valve control mechanism in internal combustion engines comprising an outer piston (4) closed on one end and insertable for displacement in the longitudinal direction in a bore (2) of a structural element (3) of the valve drive and which guides an inner piston (5) for longitudinal displacement with slight play in a longitudinal bore wherein both pistons encompass a high pressure chamber (6) therebetween which communicates via a check valve (7) arranged in the inner piston with an oil reservoir (8) provided in the inner piston (5), and wherein the inner piston (5) is supported at its end facing away from the pressure chamber by a disc (9) which is fixed in the bore (2) of the structural element (3) of the valve drive, characterized in that the disc (9) engages the bore (16) of the inner piston (5) with radially resilient clamping projections (15) upon contacting the end of the inner piston (5) facing away from the pressure chamber (16).
