2. Tappet - Wikipedia

   en.wikipedia.org/wiki/Tappet

   A tappet or valve lifter is a valve train component which converts rotational motion into linear motion in activating a valve. It is most commonly found in internal combustion engines, where it converts the rotational motion of the camshaft into linear motion of intake and exhaust valves, either directly or indirectly.

3. Desmodromic valve - Wikipedia

   en.wikipedia.org/wiki/Desmodromic_valve

   An asymmetric cam either opens or closes the valves more slowly than it could, with the speed being limited by Hertzian contact stress between curved cam and flat tappet, thereby ensuring a more controlled acceleration of the combined mass of the reciprocating componentry (specifically the valve, tappet and spring).

4. Cam (mechanism) - Wikipedia

   en.wikipedia.org/wiki/Cam_(mechanism)

   The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.

   A majority of the L05s used with the trucks and vans had conventional flat tappet camshafts, while the Caprice 9C1 (1989–93) had a roller cam. L05 usage was replaced by the LT1 after 1993 in GM B-bodies and D-bodies until production ceased in 1996.

6. Camshaft - Wikipedia

   en.wikipedia.org/wiki/Camshaft

   A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.

7. Cam engine - Wikipedia

   en.wikipedia.org/wiki/Cam_engine

   Flat Cams: Design: Flat cams, also called plate cams, have a flat surface. The edge of the surface is contoured. The contour of the edge determines the motion of the cam follower. This, in turn, determines the motion of the piston. Performance Impact: Flat cams are easy to design and manufacture. This makes them a popular choice for early cam ...
