Abstract
The invention relates to an arrangement for enabling the connection of a position sensing transducer to a machine such that the transducer is not subjected to high temperatures or dirt. In accordance with the invention the transducer is mounted on the outside of a housing in which there is mounted a rotatable means which extends outside the housing to operate a drive means for driving auxiliary equipment. The invention is distinguished in that the position sensing transducer includes a disc fixed to the drive means, said disc co-acting in non-contacting relationship with a transducer mounted on the outside of the housing for indicating the angular positions of the disc, and in that the drive means and housing include portions concentrically disposed to form a labyrinth seal to a space which accommodates the position sensing transducer. The invention is intended for use in an Otto-type internal combustion engine to connect a transducer which senses the angular position of the engine crankshaft, thus making possible control of the engine ignition timing with great accuracy.
