Coupling to connect barrel pump to drive motor

摘要

The coupling has a locking body (14,15), which moves to and fro at right angles to the axis of the pump, between a locking and a release position. The locking body has a handle to operate it. The coupling part (9) is mainly cylindrical. The locking body is born on a ring body located on the coupling part. It may form an integral unit with the coupling part. The locking body is pivoted, and is elastically deformed during the pivot movement. It is located on a torsion shaft, which is turnably held in bearings.
