Abstract: In an engine where a valve lift amount can be continuously varied, a valve- moving device, having a valve lift-varying mechanism, for an engine is capab le of increasing and reducing a valve lift amount without changing a valve opening angle and is also capable of reducing a tappet clearance according t o reduction in the valve lift amount. This prevents an increase in the ratio o f a tappet clearance to a valve lift amount in a low valve lift condition, minimizing effects by variation of a tappet clearance and also reducing a valve seating speed in a low valve lift condition to prevent noise from bein g produced. Reduction in engine performance in a high valve lift condition caused by variation of a tappet clearance is prevented and a valve seating noise in a low valve lift condition is reduced.

Abstract: The valve drive (1) incorporates a first and a second compression spring. A pre-tension force (F1vor) of the first spring (10) is arranged relative to the sum of a pre-tension force (F2vor) of the second spring (15) and a max. hydraulic medium pressure (FHyd) in a high pressure chamber (13), to give the following result :- (F1vor) greater than (F2vor) + (Fhyd). The hydraulic medium pressure is reduced by a pressure regulator (20) with electro-magnetic switching valve, or by a spring-loaded back pressure valve.

Abstract: A hydraulic lash adjuster has a generally cylindrical, hollow body having a closed end, an open end and a top land at the open end. A plunger is positioned in the body and is held in place by a retainer. The retainer is fastened to the exterior of the body. The retainer has a rim supported on the top land of the body and is held in place by tabs which are folded under into grooves in the side of the body.

Abstract: UN EMPUJA-VALVULAS HIDRAULICO (10) PARA LAS VALVULAS DE UN MOTOR INCLUYE UN PAR DE PISTONES (PCF, PVD) QUE DEFINEN UNA CAMARA DE PRESION (CP) ENTRE LOS MISMOS Y UN PISTON SEPARADO DE AJUSTE DEL HUELGO (PLA) QUE DEFINE UNA CAMARA DE AJUSTE DEL HUELGO (CLA) CON UNO DE LOS PISTONES DEL PAR. ESTRUCTURAS DE VALVULA DE PASO UNICO (V) PERMITEN EL FLUJO DE FLUIDO DESDE LA CAMARA DE PRESION (CP) A LA CAMARA DE AJUSTE DEL HUELGO (CLA), DESPLAZANDO CON ELLO AL PISTON DE AJUSTE DEL HUELGO (PLA) PARA AJUSTAR, A SU VEZ, EL HUELGO DE LA VALVULA. SE PROPORCIONAN TAMBIEN FUNCIONES DE AMORTIGUACION DEL MOVIMIENTO DURANTE UNA CARRERA DESCENDENTE DE LOS PISTONES EMPUJADORES (PCF, PVD, PLA) MEDIANTE UNA CAMARA AMORTIGUADORA DE LA VALVULA (CD) Y CONDUCTOS DE FLUIDO (90B, 112) ENTRE LAS CAMARAS DE PRESION Y AMORTIGUADORA (CP Y CD, RESPECTIVAMENTE).

Abstract: A hydraulic tappet includes a tubular cylinder sideable within a bore of a housing, a piston with a reservoir slideably mounted within the tubular cylinder, a lower piston spring biased away from the piston with the reservoir forming a pressure chamber therebetween. The reservoir being in open communication with pressure oil ports and the pressure chamber selectively being closed or open to said reservoir. The closing or opening of the pressure chamber being controlled by the lower piston and cylinder riding on tracks of a cam which control the relative position of the cylinder and lower piston.
