ABSTRACT:
Variable amplitude, linear reciprocation of an output ram is produced by converting rotary motion into linear motion using a swash plate connected by a bending element to drive a crank. The rotary prime mover and swash plate are mounted on a pivotable frame so as the axial throw of the swash plate is determined by the angular offset of the rotational axes of the swash plate and crank. When the axes are coincident the throw, and therefore the ram stroke, is zero but progressive angular displacement produces a progressively increased stroke. Thus, the frequency of reciprocation is determined by the angular speed of the prime mover, and the stroke is controllably variable between maximum and zero.
