Abstract (en)
A pump (32; 32 min ) comprises a flexible member (52; 52 min ) defining at least part of a variable volume pumping chamber, an inlet valve (31a; 71) to permit of liquid to enter the chamber thereby and an outlet valve (37; 37 min ) to permit of liquid to leave the chamber thereby, and operating means (10; 10 min ) to deform the flexible member to vary the volume of the pumping chamber to pump liquid into and out of the chamber.
