Abstract: A variable valve control arrangement for a lift valve of an internal combustion engine has a longitudinally adjustable coupling assembly disposed between a cam and the lift valve including an outer cup plunger and an inner plunger on the lift valve side and a hydraulic working space formed between the plungers. During the flanks of the valve lift curve, communication is established at times between the hydraulic working space and a pressure medium supply through the cup plunger so that at sufficiently high pressure the coupling assembly will increase its length. During the valve closing phase, the pressure in the working space is reduced through a throttle aperture in the cup plunger.

Abstract: The invention relates to a valve control system for a push-rod internal combustion engine. The valve control system includes a cam including a rotatable cam shaft having a first cam member and a second cam member having a different profile from the first raised portion. A reciprocating movement is transmitted by a rocker arm engaging the valve and a push-rod connected to a first cam follower in engagement with a push-rod operating a rocker arm and a second follower capable of movement relative to the first cam follower with locking device to enable the cam follower members to be linked so as to be moved together. When the cam follower members are not linked, the valve is controlled by the first cam follower in engagement with and following the profile of the raised portion and when the cam follower members are linked, the valve is controlled by the second cam follower in engagement with and following the profile of the second cam member, thus allowing the selection of one cam or another to accommodate different operating conditions of the engine.

Abstract: A direct acting hydraulic valve lifter of the type that is reciprocably journaled as in the cylinder head of an internal combustion engine so as to be engaged by a cam on an engine driven camshaft to control opening and closing movement of an associate valve. The lifter includes a follower body having a circular outer tubular wall with an inner integral web closely adjacent to one end thereof that terminates at a stepped bored integral depending piston, the one end thereof being closed by a disk cam engaging foot which forms with the piston and a surface of the web a fluid reservoir. A baffle, fixed to the plunger and to inner surface of the tubular wall, defines an oil supply passage which is adapted to receive fluid via a side port in the tubular wall and to be in flow communication with the fluid reservoir via an aperture in the web. A cup-shaped, closed end cylinder member slidably encircles the plunger to form therewith a hydraulic lash adjuster having a pressure chamber therein. In one enbodiment, a mechanical retainer is operatively secured to the tubular wall whereby to retain the cylinder member in unit assembly on the plunger. In a preferred embodiment, lubricating oil in the pressure chamber and in a leak-down flow path between the cylinder member and plunger and a one-way ball valve controlling flow into the pressure chamber are operative to hold the cylinder member in unit assembly on the plunger.
