The pumping assembly comprises a cam (104; 204) arranged for eccentric rotation about a drive shaft axis (A), a cam rider (106; 206) mounted on the cam (104; 204), a cam follower (112; 212) arranged for reciprocal movement in a direction parallel to a cam follower axis (Q), the cam follower (112; 212) being cooperable with the rider (106; 206) by way of a sliding interface (110, 116; 210, 216) to define a sliding axis (S), and a pumping element associated with the cam follower (112; 212) and arranged to reduce the volume of a pumping chamber during a forward stroke and to increase the volume of the pumping chamber during a reverse stroke. The rider (106; 206) is driveable by the cam (104; 204) in a direction having a first component parallel to the cam follower axis (Q) and a second component in a direction perpendicular to the cam follower axis (Q).

In another embodiment, the cam follower (212) comprises first and second surfaces (216, 216a) that cooperate with the rider (206) at the first and second sliding interfaces (210, 216; 210a, 216a), respectively, and the forward stroke of the pumping element is driven when the rider (206) thrusts against the first surface (216) during movement of the rider (206) and the return stroke of the pumping element is driven when the rider (206) thrusts against the second surface (216a) during movement of the rider (206).
