ABSTRACT:
A pressurization and regulating device uses a CO.sub.2 cartridge for pressurizing a fluid container such as the fuel tank of a gasoline lantern or stove, a garden or lawn sprayer, and the like. The device includes an elongated body having an open end for receiving the cartridge and a cap for forcing the cartridge toward the body. The other end of the body is provided with a fluid outlet opening. An outlet cap is mounted on the second end of the body. A piston is reciprocably mounted in the outlet opening of the body, and a seal on the piston is engageable with a valve seat in the outlet opening for closing the outlet opening. A spring in the outlet cap biases the piston away from the valve seat. An eccentric shaft is rotatably mounted in the outlet cap and engages the piston. The eccentric shaft is rotatable between a first position in which the seal engages the valve seat and a second position in which the spring moves the seal away from the valve seat. The outlet cap includes an internally threaded connector end.
