摘要： A muffler assembly for muffling noises associated with a compressor. The muffler assembly includes an air intake having a hollow interior for receiving air from the ambient environment when the compressor is operating. A baffle is located within the interior of the intake for restricted passage of the air through the intake. A fluid portal is defined within the baffle for enabling fluid to pass from one side of the baffle to the other side of the baffle and subsequently through said air intake. An attenuator is disposed within the fluid portal for attenuating noise and the attenuator disturbs the soundwaves associated with the operation of the compressor.

摘要： A system and method for improving the efficiency of a gas fractionalization system of the type having a compressor having an inlet for receiving air from the ambient environment. The system includes a sensor for sensing a parameter indicative of the flow of concentrated gas delivered from the gas fractionalization system to a patient. A multi-positional valve is disposed in line with the compressor for regulating the flow of air from the ambient environment into the compressor. A valve control manipulates the position of the multi-positional valve depending on the value of the parameter sensed by the sensor for regulating the quantity of air received from the ambient environment into the compressor inlet.

摘要： A gas fractionalization system including a compressor for receiving air from the ambient environment and producing a flow of pressurized air, a gas separation system for producing a concentrated gas portion from the pressurized air, a valve for controlling duration during which the compressed air is delivered to the gas separation system during a pressurization cycle, and a product chamber for receiving concentrated gas produced by the gas separation system. The gas fractionalization system includes a control system that itself includes a pressure sensor for sensing the occurrence of high and low pressures within the product chamber, a processing system that determines the pressure ratio of the high and low gas pressure within the product chamber, and a valve controller that manipulates the valve, and, hence, the duration in which the flow of pressurized air is presented to the gas separation chamber based on the pressure ratio.
