ABSTRACT:
An anti-reverse rotation device suitable for use with a single phase synchronous motor and the like, has a housing with an inner cavity, a rotatable member in the form of a disk and at least one blocking member. The cavity of the housing is bounded by an inner wall forming a cam surface with at least one abrupt change forming a blocking surface. The blocking member is accommodated within a recess formed in the periphery of the disk and moves along the cam surface as the disk rotates. In the forward direction, the cam surface urges the blocking member into the recess. In the reverse direction, the blocking member becomes jammed between the disk and the blocking surface preventing further rotation in the reverse direction.
