Test device for testing materials of push rod of valve of combustion engine and/or cam of camshaft of car, has cylinder head simulation element receiving valve provided with push rod, where geometry of element is distinct from real head

摘要

The device has a rotary shaft (30) capable of bearing a cam (20), and a drive motor for rotating the cam. A cylinder head simulation element (60) receives a valve (10) provided with a push rod (13) to be tested, where the geometry of the cylinder head simulation element is distinct from a real cylinder head. A support plate (80) and a spring (90) allow a relative position of the cylinder head simulation element with respect to the rotary shaft, where the plate and the spring are positioned on a maintenance frame (40).
