ABSTRACT:
An arrangement for converting linear motion from a power source to rotary motion, where the power source is intended to coact with a cam in a manner to produce rotary motion, this rotary motion being carried out by a shaft. The invention is characterized by a first member which comprises a rod-unit (4) or a corresponding element intended to move reciprocatingly, and the cam (2) which is attached to one end of the rod-unit, this cam having curve-shaped parts (20, 21) on solely the surface thereof remote from the rod-unit. A second member includes two mutually opposing wing-shaped parts (6, 7) which project outwardly away from the shaft and which are rigidly connected to the shaft (3). A roller (8, 9) or corresponding element is rotatably mounted on the outer part of each wing (6, 7). The rollers are intended to roll on the cam (2), therewith converting linear motion to rotary motion.
