Abstract:
A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.

Claim (Index 9):
A pump as claimed in  claim 7  wherein:\n the wall of the air vent chamber has an outer portion proximate its open inner end which is of an enlarged diameter compared to an inner portion of the wall of the air vent chamber, \n the air vent disc elastically deforming away from the chamber wall of the air vent chamber to permit air flow in the air vent chamber past the air vent flexing disc in an outward direction when atmospheric pressure is greater than the pressure in the reservoir by a pressure differential greater than a first threshold pressure when the air vent disc is in the inner portion, \n the air vent disc elastically deforming away from the chamber wall of the air vent chamber to permit air flow in the air vent chamber past the air vent disc in an outward direction when atmospheric pressure is greater than the pressure in the reservoir by a pressure differential greater than a second threshold pressure when the air vent disc is in the outer portion, \n the first threshold pressure greater than the second threshold pressure.
