ABSTRACT:
An oscillatory pump includes a cylinder (9) having normally-closed valves (10,13) of flexible material fixedly located at the inlet (A.sub.c) and outlet (B.sub.c) ends of the cylinder (9), and a piston (1) having an inlet (A.sub.p) and an outlet (B.sub.p). The piston (1) is reciprocatable within the cylinder (9) and is provided with a further valve (6) of flexible material movable with the piston (1) and located at the outlet end (B.sub.p) of the piston (1). The piston (1) is constructed to allow fluid to pass from an inlet chamber (C1) formed between the inlet valve (10) and the inlet end (A.sub.p) of the piston (1) to an outlet chamber (C2) formed between the further valve (6) and the outlet valve (13) in response of the piston (1) within the cylinder (9). The valve includes a valve seat having a generally conical first surface portion and a second surface portion located radially inwardly of the first surface portion and extending generally parallel to the axis of the first surface portion. A generally annular valve member has a tip portion for gripping the second surface portion of the valve seat with an interference fit only between the tip portion and the valve seat. A mechanism is provided for effecting reciprocatory movement of the piston (1) within the cylinder (9).
