  • Air driven liquid pump
    Patent number: 6988332
    Abstract: An air driven liquid pump includes a reservoir, a liquid inlet aperture extending through the reservoir wall for fluid coupling to a liquid inlet duct, a liquid outlet aperture extending through the reservoir wall for fluid coupling to a liquid outlet duct. The liquid outlet aperture is in fluid communication with an outlet level inside the reservoir chamber located below the liquid inlet aperture and corresponding to a predetermined lower threshold value of the volume of the liquid within the reservoir chamber. The liquid pump also includes an air aperture extending through the reservoir wall for pneumatically coupling the reservoir chamber with the atmospheric air located exteriorly to the reservoir, a liquid inlet valve operationally coupled to the liquid inlet aperture and an air valve operatively coupled to the air aperture.
