Cam drive for a temperature sensitive device

Abstract

The cam drive exhibits a part rotable about an axis. The part is unrotatably connected to a cam element. A swivel arm for a sensing element is pivot-mounted on the cam element. A temperature-dependent compensation element is provided which is supported on the cam element and engages in the swivel arm to determine the position thereof. The sensing element is arranged on the swivel arm such that it can be moved and engages in a recess of the cam element. The recess is adapted to the type-specific temperature dependence of the temperature-sensitive device which the cam drive forms a part of. The error curve of the temperature-dependence device can be optimized by appropriate radial and tangential adjustment of the sensing element (stroke and advance), caused by the compensation element and determined by the corresponding design of the recess.

Dependencies are inferred from the claim text.
