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).

Abstract: A simply constructed and easy-to-produce nozzle valve (1) for oil spraying of pistons in internal combustion engines is provided. The nozzle valve (1) is formed from a thin-walled sheet-metal housing (2), a nozzle (12), a valve body (8), and spring means (10) for the valve body (8). The spring means (10) act at one end directly against the valve body (8) and rest at their other end against a support (11) extending within the housing (2). This support (11) forms a single structural unit together with the nozzle (12).

Abstract: A traction mechanism drive having a hydraulic tensioner (1) which has a housing (2) fabricated from a light-metal alloy in which a slide sleeve (4) manufactured of steel is inserted that has an axially extendable piston for deflecting a tensioning and guide unit, such as a roller or a rail, a securing element (11) being clampingly disposed between the housing and the slide sleeve to prevent the slide sleeve (4) from moving out of the housing (2). Also, an internal combustion engine having such a traction-means drive and a tensionable traction means.
