Abstract
A multi-stage compressor comprises a gas compressor, a centrifugal blower having an input connected with a gas source and an output connected with the gas compressor and providing a flow of compressed gas as a first stage of compression to the gas compressor, and a power source mechanically connected with and driving both the centrifugal blower and gas compressor to provide multi-stage compression of said gas.
Claims27
A five-stage, high flow rate, high pressure compressor, comprising:
- a compressor block having a plurality of cylinders in two banks, including pistons connected with a crankshaft driven by an external power source, and valve means for controlling the flow of gas to and from the cylinders;
- a centrifugal blower for providing a compressed gas output as a first stage of compression;
- a mechanical drive connected between the crankshaft and the centrifugal blower;
- first means connecting the centrifugal blower output with an intake manifold for the cylinders of one bank of cylinders of the compressor block, said pistons of one said bank of cylinders operating in parallel as a second stage of compression to further compress the compressed gas output of the centrifugal blower and to direct the further compressed gas to an exhaust manifold for said one bank of cylinders;
- second means connecting the exhaust manifold of the first bank of cylinders with one or more of the cylinders of the second bank of cylinders, said one or more cylinders having a volume smaller than the cylinders of said first bank of cylinders, the one or more pistons of said one or more cylinders operating as a third stage of compression of said compressed gas;
- third means connecting the compressed gas from said one or more cylinders with a further cylinder of said second bank of cylinders, said further cylinder having a volume smaller than said one or more cylinders, said piston of said further cylinder operating as a fourth stage of compression of said gas;
- and
- fourth means connecting the compressed gas from said further cylinder of said second bank of cylinders with an output cylinder of said second bank of cylinders, said output cylinder having a smaller volume than said further cylinder, said piston of said output cylinder operating as a fifth stage of compression of the compressed gas and providing a compressed gas output at high flow rates and high pressures.
A multi-stage, high flow gas compressor, comprising a compressor block having a plurality of cylinders, each of the plurality of cylinders containing a reciprocatable piston connected to a crankshaft that may be driven by an external power source to reciprocate within the cylinder, each of the cylinders being provided with valve means to control the flow of gas into and out of the cylinder;
- said cylinders of said compressor block being interconnected in series so their pistons, when driven, further compress a flow of compressed gas directed to a first one or more cylinders of said plurality of cylinders to provide a compressed gas output;
- a centrifugal blower for providing a flow of compressed gas to said first one or more of said cylinders;
- and
- a mechanical drive connected between said crankshaft and said centrifugal blower, said mechanical drive operating said centrifugal blower at speeds in excess of 9000 rpm as a first stage of compression.
A multi-stage gas compressor assembly comprising
- an internal combustion engine;
- a centrifugal blower driven by a mechanical connection from the internal combustion engine and providing a compressed gas output as a first stage of compression;
- a rotary screw compressor driven by a mechanical connection from the internal combustion engine, having an input connected with the compressed gas output of the centrifugal blower, providing a second stage of compression and having a further compressed gas output.
A multi-stage gas compressor, comprising
- a gas compressor;
- a centrifugal blower having an input connected with a gas source and an output connected with said gas compressor and providing a flow of compressed gas as a first stage of compression;
- and
- a power source mechanically connected with and driving both said gas compressor and said centrifugal blower to provide multi-stage compression of said gas.
