Housing 1 rotates about fixed axis A. Slider 3 reciprocates along axis y-y in guide slot a of housing 1. Piston 2 reciprocates along axis x-x of guide slot b in slider 3 and is connected by a turning pair to fixed circular eccentric cam 4. Axes x-x and y-y are at right angles. Housing 1, rotating about axis A, is also used as a pulley. This rotation reciprocates piston 2 and slider 3 along perpendicular axes. Eccentric cam 4 is rigidly secured to axis A. The motion of piston 2 is used to pump a liquid.
