摘要： Herein disclosed is a pump comprising a chamber including a liquid inlet port. Located within the chamber are: a buoyant valve, responsive to liquid level and vapor pressure within the chamber to open or close said port; a cartridge heater for vaporizing part of the liquid in the chamber; and, a liquid delivery conduit extending from within said chamber to the outside thereof. The heater vaporizes some of the liquid in the chamber and the vapor pressure thereof pushes liquid through the conduit.

摘要： Disclosed is a vapor push pump having a housing adapted to be immersed in a liquid to be pumped. Within the housing a chamber is defined; the chamber communicates with the liquid outside the housing via a port provided in the housing. A heater in the chamber vaporizes some of the liquid admitted to the chamber through said port. Vapor pressure in the chamber forces (pushes) the liquid through a liquid delivery conduit, passing through the housing, to a location outside the housing and above the level of the liquid in which the housing is immersed. A buoyant first valve body moves and closes, or opens, said port, as a function of the head of liquid outside the housing, the weight of the first valve body, the level of liquid in the chamber and the vapor pressure in the chamber and surface tension. Also provided is a vapor vent conduit passing through said housing to vent vapor in the chamber to a location outside the housing and above the external liquid level. A buoyant second valve body within the chamber moves to close or open the vapor vent conduit as a function of the weight of the second valve body, the level of liquid in the chamber and the vapor pressure in the chamber and surface tension. Also, the first valve body is caused to open abruptly when the second valve body operates to vent the vapor pressure from the chamber.
