STROKE-LIMITING COLLAR FOR A PISTON AND CYLINDER

In order to limit the stroke of the piston of a piston and cylinder unit a spacer collar (10) or collars is or are fitted around the piston rod (30). Each collar (10) comprisesa pair of identical cam members (11a, 11b )formed with flanges (14, 16) at one end. The flanges of one cam member (11a, 11b)...

Zusammenfassung:	In order to limit the stroke of the piston of a piston and cylinder unit a spacer collar (10) or collars is or are fitted around the piston rod (30). Each collar (10) comprisesa pair of identical cam members (11a, 11b )formed with flanges (14, 16) at one end. The flanges of one cam member (11a, 11b) are slidable on the complimentary flanges (16, 14) of the other cam member on relative rotation of the cam members. This alters the spacing of abutment surfaces (32) at the other (i.e. outer) ends of the cam members and thus changes the limit of the stroke. The flanges (14, 16) have bolt-receiving slots (22, 24) so that the cam members can be bolted together. The cam members also have U-shaped rod-receiving slots (28) for ease of removal from the rod (30).
