Rotary motion of a shaft 1 is converted into linear reciprocating motion of pistons 3, or vice-versa, by means of a multiple bell crank lever 2 comprising two or more first arms connected at a fulcrum and radiating in a plane and a single second arm connected to the first arms at said fulcrum and extending along a radius perpendicular to said plane. <IMAGE> |
