BOOSTER COMPRESSOR INTEGRAL WITH MOTOR

WIPO Patent Application WO/2011/125681

A1

Disclosed is a unrefuel-type booster compressor integral with a motor, wherein a piston ring is composed of a self-lubricating resin, said piston ring being configured to supply gas to be compressed, which has been introduced to a crank chamber, to the inside of a cylinder through a communication path, to compress the gas. In a speed control mechanism (60), a centrifugal force governor is switched to an electronic governor (66). A starting capacitor (86), an operating capacitor (88), and the electronic governor (66), which constitute the speed control mechanism (60), are arranged on the outside of a motor case (18). Furthermore, these devices are arranged so as not to block the flow of cooling air (a) discharged from an electric fan (74), and the flow of cooling air is maintained so as to be along the outer peripheral surface of the motor case (18), so that the cooling effect of the motor case (18) can be maintained at a high level.
