CILINDRO MOTORE AZIONATO DA FLUIDO IN PRESSIONE.

摘要

A working cylinder (1) is proposed which translates a reciprocating movement into a rotational movement of its piston rod (5) by means of a toothed shaft (20) with oblique and wedge-shaped teeth. The toothed shaft (20) can be produced without requiring a large amount of material. The rotary drive is provided for a bus door or the like.
