Abstract

A diaphragm pump (10) comprising:
a chamber (12) opening at opposite end portions to provide an inlet (14 and an outlet (16), and including an aperture (30) defined in a surface of the chamber between the inlet and outlet;
a flexible diaphragm (40) having an inner region (42) and an outer region (44), the outer region (44) sealing against the surface of the chamber surrounding the aperture to close off the aperture, the chamber and the diaphragm (40) thereby defining a passageway (50) providing fluid communication between the inlet and outlet;
a one-way inlet valve (25) coupled to the inlet (14) and a one-way outlet valve (27) coupled to the outlet (16);
the inner region (42) of the diaphragm (40) being reciprocatable within the chamber (12), whereby on reciprocation of the inner region fluid is drawn in via the inlet valve and expelled via the outlet valve,
wherein the diaphragm (40) is angled such that the plane of the diaphragm faces the outlet (16).
