ABSTRACT:
A pump for liquids including a rotor containing bores housing slidable pistons. A stroke member is associated with the pistons and constraining the pistons, when the rotor rotates, to orbit about an axis parallel to the axis of rotation of the rotor. The spacing between the two axes occasions reciprocation of the pistons within their bores to perform a pumping action. Each piston has coupled thereto a U-shaped member within which is engaged a crosshead of the stroke member. The crosshead is movable slidably within the U-shaped member as the pump operates.
