摘要

The ceiling mounted revolver of a car wash has a magnetic position holder (20) installed between the rotatable revolving arm (11) and an optional stationary element of the washing bay (1) and which releasably keeps the arm in its initial position (30). The optional stationary element may be the roof (2) and/or the wall (3) of the wash bay. The position holder may have at least one permanent magnetic or at least one electromagnet. The magnet acts directly or indirectly on the magnetic material of the rotatable arm in the arm's initial position.
