(Otomotiv) The rods that run between the camshaft or camshaft lifters and the rocker arms. The lifters and the push rods are pushed up by the cam lobes, causing the rocker arms to make the valves open and close. Engines with overhead cams don't need push rods because the camshaft cam lobes contact the valves directly
A general term for any rod that transfers force in compression In a valvetrain, pushrods are used to transfer reciprocating motion from the cam followers to a more distant part of a valvetrain, typically the rocker arms
A general term for any rod that transfers force in compression In a conventional overhead valve layout, pushrods are used to transfer reciprocating motion from the cam followers to a more distant part of a valve train, typically the rocker arms Pushrods are eliminated in overhead camshaft designs
