Crank 1 rotates about fixed axis A and is connected by turning pair B to link 2 which has a spherical bearing. Axes A and B intersect at point O, the centre of the spherical bearing. Wobble plate a, mounted perpendicular to the axis of link 2, rolls over two fixed cones b of the housing. When crank 1 rotates, plate a delivers liquid in the chambers of the pumip from suction input d to discharge output e. The suction and discharge chambers are separated by partition f in the plane of the drawing.
