A shaft fitted with several cams, whose lobes push on valve lifters to convert rotary motion into linear motion. The opening and closing of the valves in all piston engines is regulated by one or more [..]

(n) has cams attached to it

A shaft having one or more cams attached to it.

shaft with protruding eccentric lobes. As camshaft rotates, lobes cause reciprocating movement of other valve train parts.

 A shaft containing many cams that convert rotary motion to reciprocating (lifting) motion. For every 2 revolutions of the crankshaft, the camshaft rotates 1 revolution. The lobes on the camshaft actu [..]

A machined shaft with lobes that open and close engine-cylinder intake and exhaust valves. As the shaft rotates, the lobes push against valve springs to open the valves and rotate away to close them. [..]

A rotating shaft in the engine that opens and closes the engine’s intake and exhaust valves. 

A shaft with bumps which is driven by gears, a belt, or a chain from the crankshaft. The bumps push on the valve lifters to cause the valves to open and close. The camshaft turns at half the speed of [..]

A shaft fitted with cams; especially one in a piston engine that activates the valves.
