ABSTRACT:
A pump or motor 10 provides a housing 20 which carries one or more elliptical drivers 40 which rotate freely with an axle which is rotatably carried by the housing. One V-shaped rocker 60 is associated with each elliptical driver, and moves in an oscillatory motion in response to being driven by the associated elliptical driver. When used as a motor, fluid entering the housing tends to apply pressure to one side of the elliptical driver, while the other side is shielded from pressure by the V-shaped rocker. Uneven pressure causes the elliptical driver to rotate. As the elliptical driver rotates, the V-shaped rocker oscillates in a period manner at twice the frequency of the elliptical driver. The vertical height of the V-shaped is determined by an adjustable support 80, which allows regulation over the friction level and fluid seal between the rocker and the elliptical drive, and which allows adjustment to compensate for wear of the surfaces of contact between the rocker and the elliptical driver.
