  • Mechanical valve clearance compensator for internal combustion engines
    Patent number: 4409935
    Abstract: A mechanical valve clearance compensator for internal combustion engines with cup tappet operation. A wedge provided with a wedge-shaped surface is supported in the cup tappet to be displaceable at right angles to a travel direction of the cup tappet. The wedge is under a constant action of a compression spring which acts in a direction toward clearance compensation and is intermittently acted upon in an opposite direction by an operating cam fixedly connected with the cam shaft. The operating cam is fashioned as a radial cam and acts upon a pin longitudinally displaceably guided in the cup tappet. The pin, in turn, is supported on a sliding surface of a wedge, with the sliding surface having a greater inclination than an inclination of the wedge-shaped surface.
