Abstract
A hydraulic compressor arrangement includes hydraulic rams A and B with associated non-return valves. A hydraulic pump, typically electrically operated, provides a pressurized fluid source to operate rams A or B to allow the associated chambers to receive and compress the low pressure gas provided by a valve. The rams A and B alternately compress and allow entry of the gas so as to produce a continuing source of compressed gas by a pipe to a gas storage tank by a quick release coupling. Two stage compression can also be utilized.
Claims16
A fluid compressor having two stages of compression including first and second chamber, each for receiving a first fluid to be compressed;
- means for receiving a second fluid under pressure in each of the first and second chambers to effect compression of the first fluid by reducing its volume;
- a piston provided in each chamber to separate the first and second fluids, wherein at least the first stage piston has a piston area for the first fluid which is larger than the piston area of the pressurized fluid;
- and
- each piston is driven by a ram rod and the ram rods have differing diameters.
A method of compressing a first fluid comprising the steps of providing the first fluid to be compressed to a first or second fluid chamber, providing a source of pressurized second fluid to the first or second chamber to reduce the volume of the first fluid within the respective chamber to compress it and wherein a piston is provided in each chamber to separate the first and second fluids and wherein at least the first stage piston has a piston area for the first fluid which is larger than the piston area of the pressurized fluid and each piston is driven by a ram rod and the ram rods have different diameters.
