ABSTRACT OF THE DISCLOSURE The invention relates to piston-and-cylinder devices having an output member adapted to drive vehicles, generators or other mechanical arrangements. The device may in its simplest form comprise a cylinder including a chamber at least one piston having an exterior cylindrical surface, and which is adapted to partake of a motion having a component of movement lengthwise of the cylinder and a rotatable output member. There are also provided cam means comprising a first cam part and a second cam part, one of said cam parts being a cam track arrangement formed for example in the piston surface and the other being a cam follower means formed on the inside surface of the cylinder and adapted to engage said track arrangement, the construction and operation being such that said cam means operates to impart to the motion of the piston a rotational component of movement and such that rotary motion produced in the output member is derived from said rotary component of movement of the piston motion. Conveniently, a skirt flange may be provided on the piston to act as a sleeve valve.
