Einrichtung zur Anzeige der Drehrichtung einer rotierenden Pumpe

摘要

A drive housing secured bearing plate (28) is located between the carrying plate (19) and a transparent cover (36). It has at least one circular track (32, 33), concentric to the longitudinal axis (9), for an indicating body (34, 35) influenced by the drive magnets (21a, 21b). The carrying plate has a shaft stub (23) pointing to the adapter (12) for connecting to the pump shaft (2), which projects rotation proof and longitudinally movable in a blind hole (14) of the adapter. The adapter has a same size spring reception plate (16) opposite the carrying plate. A compression spring (26), coaxial to the longitudinal axis, is provided between the reception and carrying plates.
