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.
In a gas-compressing system:
In a system for compressing combustible fuel gas lighter than air:
In a gas-compressing system, a working cylinder, a gas-supplying component for introducing gas into said working cylinder when the pressure of gas in said working cylinder is below the pressure of the gas supplied by said gas-supplying component, liquid control means for alternately introducing liquid into said working cylinder for forcing gas from it and draining liquid from said working cylinder so as to cause said working cylinder to be refilled with gas from said gas-supplying component, means preventing backflow of gas from said working cylinder to said gas-supplying component as gas is forced from said working cylinder, a storage cylinder, means directing the gas forced from said working cylinder into said storage cylinder, means preventing backflow of gas from said storage cylinder to said working cylinder, a portable tank having an inlet connectible to said storage cylinder for receiving gas from said storage cylinder, and means for introducing liquid into said storage cylinder so as to force gas from said storage cylinder into said portable tank.
In a gas-compressing system:
In a system for compressing a combustible gas, a working cylinder, a gas-supplying component for introducing such combustible gas into said working cylinder when the pressure of the gas in said working cylinder is below the pressure of the gas supplied by said gas-supplying component, a reservoir containing a supply of operating liquid, a pump for drawing liquid from said reservoir and for pressurizing such liquid, liquid control means for alternately introducing liquid under pressure from said pump into said working cylinder for forcing gas from it and draining liquid from said working cylinder so as to cause said working cylinder to be refilled with gas from said gas-supplying component, said liquid control means including means for returning liquid drained from said working cylinder to said reservoir, means preventing backflow of gas from said working cylinder to said gas-supplying component as gas is forced from said working cylinder, a storage cylinder, means directing the gas forced from said working cylinder into said storage cylinder, and means preventing backflow of gas from said storage cylinder to said working cylinder.
