    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.

    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).

    Abstract: Provided is a variable valve device for an internal combustion engine. The variable valve device includes intake- and exhaust-side swing arms that pivot to open and close intake valves and exhaust valves in two cylinders #1, #2, intake- and exhaust-side hydraulic lash adjusters that serve as pivot points of the respective swing arms, a variable valve system that continuously varies valve lift characteristics of the intake valves and lost motion mechanisms that stop opening and closing of the intake exhaust valves by lost motion of the intake- and exhaust-side hydraulic lash adjusters on the cylinder #1. The maximum valve lifts of the intake valves are set larger than valve lifts of the exhaust valves. The minimum valve lifts of the intake valves are set smaller than the valve lifts of the exhaust valves.
