Abstract: A centrifugal gas compressor fed with a gas and a processing liquid comprises a rotor rotated by a prime mover. The rotor defines an internal axial cavity with a cylindrical surface, an annular peripheral collection cavity, and a tapered radial channel fluidly connecting the internal axial cavity and the annular peripheral collection cavity. With each rotation of the rotor, a portion of the processing fluid is swept into the inlet of the tapered radial channel and travels radially as a fluid piston under centrifugal force pushing and compressing a column of gas entrained in front of said fluid piston, and is expelled into the annular peripheral collection cavity where it undergoes centrifugal separation, leaving the compressed gas to be drawn off through the compressed gas outlet for downstream use. A method for compressing a gas is also provided.

Abstract: A centrifugal gas compressor with rotating hollow housing and an independently rotating, turbine compresses gas bubbles in capillary tubes and recovers energy from the liquid drain (sometimes a liquid recycler). The housing rotatably retains an internal spool having the turbine. Gas-liquid emulsion fed to the capillaries generates compressed gas-liquid emulsion at a radially distal annular region in an annular lake within the spool. Compressed gas leaves the lake and is ported away. A turbine blade edge in spilt over liquid drives the turbine, converting angular velocity/momentum into shaft torque as recovered energy. Blade captured liquid is recycled to capillary inputs.

Abstract: A centrifugal-type ejector machine of the invention comprises a sealed housing with a rotating rotor. The interior of the housing is filled with a liquid. The rotor has a central axial opening and is provided with a plurality of radial channels leading to the outer periphery of the rotor in a substantially tangential direction to the rotor periphery. The device operates as a compressor or a vacuum chamber based on the principle that difference of speeds between the periphery of the rotating rotor and stationary liquid created a negative pressure at the exit of radial channels of the rotor connected to the source of gas, which is extracted from the channels of the rotor into liquid and is removed through the outlet port of the compression chamber. In case the device works as a vacuum chamber, evacuation occurs through the aforementioned radial channels and the hollow shaft of the rotor.

Abstract: An improved fluid detection mechanism for a canned motor pump includes a return passage which receives a fluid detector. The fluid detector is a bubble detector which can sense the presence of bubbles, or the lack of a fluid. The detector is preferably positioned in a return path for returning a cooling and lubricating pump fluid back to the pump chambers from the canned motor chamber. This location will likely be the hottest location and the lowest pressure location in the pump. This location provides a very good indication of when the motor is overheated. Also, the location provides a very good indication to identify the lack of adequate lubricating and cooling fluid being directed to the bearings. As such, the location provides benefits over the prior art.

Abstract: A centrifuge gas compressor for compressing gases to higher pressure states having a housing hollow interior, inside the hollow interior is a distributor and a rotating disc; the distributor is used for channeling gas and liquids into the rotating disc. The rotating disc contains a multiplicity of compression conduits extending perpendicular from a rotating axis of said disc whereby gas and liquids are channeled through. The spinning disc creates centrifugal force on the gas and liquid mixture and forces the mixtures towards smaller exit openings thereby compressing the gas in the process. The compressed gas then exits the spinning disc at a perimeter opening whereby the high-pressure gas can be used for its intended purpose.

Abstract: A multiple disk compressor has a through flow of a two-phase medium consisting of gas bubbles entrained in a non-miscible liquid carrier and causes an almost isothermal compression of the gaseous phase of the medium. Because of the larger density at a given tip speed, much higher pressure ratio is obtained in a single stage than can be obtained in a conventional compressor having a throughflow of gas only. The liquid carrier, after separation from the compressed gaseous medium, provides heat to a heat exchanger before being reduced in pressure and returned to the compressor. The separated gaseous medium under pressure is withdrawn as the useful product.
