ABSTRACT:
An arrangement for converting linear motion from a power source to rotary motion, wherein the power source is intended to coact with a cam curve so as to generate rotary motion, the rotary motion being performed by an axle; wherein the arrangement includes a rod (4) or corresponding element which is connected to a piston (31) mounted for reciprocating movement in a cylinder (30; 50) through the action of a pressure medium which is intended to act on that side of the piston (31) which is opposite to that side on which the rod (4) is connected to the piston, and further comprises the cam curve (2) which is mounted on one end of the rod (4) and which has curved parts (5) solely on that side thereof which faces away from the rod (4), and wherein the arrangement includes second means which comprises two opposing wing-shaped parts (6, 7) which project outwards away from the axle and which are firmly connected to the axle (3), and wherein a roller (8, 9) is mounted on the outer part of each of the wing-shaped parts and is intended to roll against the cam curve (2). The invention is characterized in that the piston rod (4) moves through a hole (36) provided in a lower wall (37) of the lower part of the cylinder, so that the cylinder space located beneath the piston essentially forms a chamber (38); in that when occupying its upper and its lower position, the cam curve will be located on the opposite side of the lower wall (37) in relation to the piston (31); in that the chamber (38) has at least one connection (32, 40;51, 40) with the surroundings; and in that the connection (32, 40; 51, 40) is so constructed that an overpressure will be generated in the chamber (38) as the piston (31) is moved from its upper position to its lower position.
