Cash Research Screw Compressors Patents
Anthony Kitchener secured patents to compressor technology dating back to 1984.
1984 Flooded compressor separators
A separator for a flooded liquid/gas compressor comprising a pressure vessel having an inlet for compressed liquid/gas mixture, a lower outlet for liquid and an upper outlet for clean gas, a filter element interposed between the liquid/gas mixture inlet and the clean gas outlet through which the gas flows to said outlet, and a shield member at least partially surrounding the filter element whereby liquid from the separator pressure vessel is prevented from contacting the filter element during periods of operation when the liquid volume in the pressure vessel may rapidly expand.

1984 Compressor control system
A control valve configuration for a compressor system comprises a compressor receiving gas and liquid lubricant for compression and delivery to a separator where the compressed gas is separated from the liquid and passed to an end use with the liquid being recycled to through the compressor. The control valve configuration is arranged to control flow through the gas inlet to the compressor in response to demands of the compressor system and mechanisms are provided to supply pressurized gas to the inlet zone of the compressor upon the valve configuration moving towards a position preventing flow of gas to the compressor to thereby reduce vacuum conditions in the inlet zone thereby reducing transient noises associated with compressor operation and minimizing power consumption during no load operation.

1987 Compressor system
A compressor system arrangement of the type arranged to compress a liquid gas/mixture and discharge same into a separator vessel where the compressed gas is separated from the liquid and passed to a clean compressed gas outlet. To make such compressor systems competitive with other gas compressors it is necessary to make the overall system package smaller and to achieve this in accordance with the present invention, the compressor (7) is housed substantially within the separator vessel (2) and the filter element (4) is annularly disposed adjacent to a circumferential wall (22) of the separator vessel (2) with the filter element 4 being preferably housed within a dry sump compartment defined by a partition wall (40) with one or more access openings (42,63,3) located in an upper region of the separator vessel (2) in a position of use of the compressor system.

1993 Separator vessel
A flooded compressor system has a compressor unit (10) with intermeshing rotors and a separator (12) for retaining a volume of liquid. The separator (12) is arranged to receive compressed gas and liquid discharged from the compressor unit (10) through an outlet (17) and is formed solely by a single length of pipe of substantially uniform cross section which has a first substantially horizontal portion (19) to retain a liquid pool (18) and a second elevated portion (23) connected to the first portion by a bend in the pipe. A compressed gas outlet (25) leads from the second elevated portion to a separate filter element (14), and a liquid filter element (30) is mounted from, and communicates directly with the first horizontal portion of the pipe.

1996 Tank mounted rotary compressor
A rotary compressor having a drive motor and a single pressure vessel, wherein the pressure vessel acts both as a gas oil separator and as a compressed gas storage tank. The compressor employs a control for valves in order to close off the supply of oil and gas from entering the compressor prior to cessation of the compressor's rotation.

1996 Inlet control combination for a compressor system
A flooded compressor control system that comprises a flooded compressor (11), an inlet throttle valve (14) and a final filter (25) mounted separately from a separator vessel (23) wherein the inlet throttle valve (14) and the final filter (25) form a combined assembly, the final filter (25) further incorporates a minimum pressure valve (28) that controls the discharge of clean compressed gas from the final filter (25) resulting in a reduction in the number of pipe joints in the system.

2001 Integrated compressor drier apparatus
A rotary compressor system having a drive rotary compressor unit, a separator vessel (13) receiving compressed gas and entrained liquid from said compressor for collecting the liquid therein and for returning the liquid to a lower pressure zone of the compressor and a moisture absorber receiving compressed gas flow leaving a separation zone of the separator vessel and passing the compressed gas flow relative to a flow of said liquid such that moisture in the compressed gas flow is transferred to said liquid.
