Abstract
Combustible fuel gas at low or moderate pressure is supplied to an inlet in the top of an upright working cylinder. The working cylinder then is filled with liquid through a bottom liquid inlet to force the gas from the cylinder and direct it into a storage cylinder. A check valve prevents backflow of gas from the storage cylinder as the liquid is drained from the working cylinder and as the working cylinder again is filled with low or moderate pressure gas. The process of filling the working cylinder with liquid to force the gas from it into the storage cylinder and holding the gas in the storage cylinder while the liquid is drained and the working cylinder is refilled with gas is repeated until the gas in the storage cylinder is a desired high pressure, such as 1500 psi or higher. Two working cylinders can be provided so that, as one of them is drained, the other is filled with liquid, such that gas is substantially continuously forced into the storage cylinder until the desired high pressure is achieved.
