摘要： A pump (1) comprising a stator (4) and a rotor (6) axially and rotatably movable relative to the stator, the stator (4) comprising a piston chamber (10) comprising a radial surface (30), an inlet (3) comprising an inlet mouth (28) formed in the radial surface and an outlet (5) comprising an outlet mouth (29) formed in the radial surface, the rotor (6) comprising a piston portion (13) comprising a radial surface (16), an end face (15) and a non-axisymmetric indent (14) formed between the radial surface (16) and the end face (15) of the piston portion (13), wherein the indent (14) is arranged to overlap at least partially the inlet mouth (28) over a range of angular positions of the rotor relative to the stator corresponding to a pump intake phase, and arranged to overlap at least partially the outlet mouth (29) over a range of angular positions of the rotor relative to the stator corresponding to a pump expel phase, and wherein the radial surface (16) of the piston portion (13) is configured to close the outlet mouth (29) during the pump intake phase, the inlet mouth (28) during the pump expel phase and both the inlet and outlet mouths (28) between the pump intake and expel phases. The stator (4) comprises a flexible elastic membrane (7) sealingly separating the piston portion (13) from the piston chamber (10).
