Abstract: A system for controlling the opening and closing, as well as the lift, of the intake and exhaust valves of an internal combustion engine as a function of the speed of the engine. In one form of the invention, the system includes a variable length tappet assembly which, in cooperation with a push rod and rocker assembly, functions to open and close the valves of the engine in direct relation to engine speed. The variable length tappet assembly is operably coupled with the oil pump of the engine, the output pressure of which varies as a function of engine speed with the result that the overall length of the tappet assembly also varies as a function of engine speed.

Abstract: An engine variable camshaft timing phaser (10) includes a sprocket (12) and a planetary gear assembly (14). The sprocket (12) receives rotational drive input from an engine crankshaft. The planetary gear assembly (14) includes two or more ring gears (26, 28), multiple planet gears (24), a sun gear (22), and a wrap spring (76). One of the ring gears (26, 28) receives rotational drive input from the sprocket (12) and one of the ring gears (26, 28) transmits rotational drive output to an engine camshaft. The sun gear (22) engages with the planet gears (24). The wrap spring (76) experiences expansion and contraction exertions to permit advancing and retarding engine valve opening and closing, and to prevent advancing and retarding engine valve opening and closing.

Abstract: A valve stem which is located for axial movement; a valve lever is pivotally mounted at one end and is attached adjacent the other end to the end of the valve stem, the valve lever defines a track; a drive pin engages in the track the drive pin being mounted at one end of a first link the other end of the link being pivotally mounted about a fixed pivot, a second link is pivotally mounted at one end about moveable pivot, the first and second links being interconnected by an intermediate link pivotally attached to said first and second links at positions separated from their pivots, a drive link is pivotally connected at one end to the pivotal connection between the second link and intermediate link and at the other end to a crank, so that rotation of the crank will cause the linkage to oscillate and the drive pin to perform a reciprocating motion along an arcuate path; the trank has a first portion which is engaged by the drive pin when the valve is closed and coincides with the arcuate path of the drive pin and a second portion which diverges from the path of the drive pin, so that engagement of the second portion by the drive pin will cause the valve lever to move opening and closing the valve; and means being provided for movement of the pivot to vary the timing and duration of opening of the valve.

Abstract: A valve mechanism includes a poppet type valve, a valve lever pivotally mounted at one end and attached at the other end to the end of the stem of the valve, the valve lever defines a track in which is located a drive pin and a drive mechanism is arranged to drive the drive pin in oscillatory manner; the track has a first portion which, when the valve is closed is engaged by the drive pin and coincides with the path of the drive pin, and a second portion which diverges from the path of the drive pin so that when engaged by the drive pin movement of the drive pin will cause the valve lever to move, opening and closing the valve. Preferably the mean position of oscillation of the drive pin is adjustable so that the duration and amplitude of valve opening may be varied.
