An apparatus for converting linear motion into rotary motion or vice versa comprising a shaft (12) which is rotatable about a fixed axis (14) and carrying a circular cam (16) mounted eccentrically relative to that axis (14), the cam (16) being rotatably mounted within a disc (22) which is in turn rotatably mounted within a housing (24) mounted for linear reciprocating motion along a rectilinear axis (26) in a direction transverse to the axis (14) of the shaft (12) whereby reciprocating motion of the housing (24) along the rectilinear axis (26) is converted into rotation of the shaft (12), or rotation of the shaft (12) is converted into reciprocating motion of the housing (24) along the rectilinear axis (26). |
