摘要： The invention relates to a mechanical valve gear that can be variably adjusted for at least one gas shuttle valve (1) in a piston internal combustion engine, said valve being provided with at least one closing spring (2). Said valve gear comprises a drive element (13) for generating a stroke motion that acts against the force of the closing spring (2) on the gas shuttle valve (1) and a stroke transmission element (4) located between the drive element (13) and the gas shuttle valve (1). Said transmission element acts on the gas shuttle valve (1) in the direction of the displacement axis (14) of the latter and the stroke path of the stroke transmission element can be modified in the direction of the displacement axis (14) by means of an adjustable guide element (11). The stroke transmission element consists of a pivoting element (8), whose end that acts in the direction of the displacement axis (14) interacts with the gas shuttle valve and whose end that faces away from the gas shuttle valve (1) is connected to the drive element (13). Said pivoting element can be directed in a pivoting manner back and forth on a guide element (11) that is configured as a radial cam (11.1).

摘要： 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.

摘要： 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.

摘要： This invention proposes a poppet valve actuation system in which the poppet valve is operated, via a cam follower, by a cam, which has a shaft passing through it, concentric with the bearings that support the aforementioned cam, and the said cam being joined by (2) pivoted links to a connecting rod, driven by a crankshaft, the first link, referred to as the "cam link", being rotatably connected at one end of the link to the cam, whilst the other end of the first link connects rotatably to one end of the second link, this second link, referred to as "control link" being rotatably connected, along its length, to the small end of the said connecting rod, the other end of this second link, termed the "free" end, being connected, via an appropriate mechanical joint, to an actuator that may apply a displacement to this free end of the control link, such that the control link's angularity relative to the first link and therefore the angular displacement of the cam can be adjustably controlled by the said displacement of the free end of the control link causing rotation about the connection of the control link with the small-end of the said connecting rod, the big end of which being free to rotate on the said crankshaft, the said crankshaft being driven in appropriate phase with the main engine crankshaft, and said crankshaft being on a parallel and different axis to that of the aforementioned bearing support shaft that passes through the cam. The actuator may be electrically driven and controlled, in response to signals from a sensor on the poppet valve or actuator shaft, in feedback or feedforward mode.
