Abstract
A gauge for measuring the clearance between a cam of an engine camshaft and the relevant valve, during rotation of the camshaft, comprises a first movable feeler element, for contacting the cam profile, and a second movable feeler element, for contacting a surface, facing the cam, of the valve or of an element coupled to the valve. A retraction device can displace the second feeler element from a rest position to an operating position. Gauging heads provide a signal depending on the mutual position of the first and second feeler elements and a processing circuit processes these signals to obtain the clearance.
