Latest Patents

Fraser holds a patent for a "Feedback control system for helical screw rotary compressors." This invention involves an air motor that responds to changes in pressure within a compressed air supply line. It effectively controls the flow of hydraulic motive fluid to a hydraulic motor, which in turn drives the capacity control slide valve of a helical screw rotary compressor. This design aims to eliminate hunting of the slide valve, which shifts in response to changes in compressor load. A mechanical feedback from the hydraulic motor modulates the flow of motive fluid to ensure optimal performance.
