Coupling device for coupling waste gas valve drive to waste gas valve of combustion engine of motor vehicle, has coupling elements operating together in coupling position without clearance in tangential direction

摘要

The device (1) has two coupling elements (2, 3) rotatably mounted and coupled with each other such that torque of one coupling element is transferred to another coupling element. The coupling elements operate together in a coupling position without clearance in a tangential direction and with clearance relative to each other in a radial direction. One of the coupling elements comprises an eccentrically arranged and/or projected element i.e. pin (8) that is engaged with a recess or slot of another coupling element in the coupling position.
