PREVENTING DEVICE FOR FLOW OF OIL IN SCROLL COMPRESSOR

PURPOSE:To enable improved supply of oil when the compressor is started again by providing a non-return valve in the oil supply line to prevent flow of oil from the fuel supply line to the low pressure area when the compressor is stopped. CONSTITUTION:Non-return valve 8 is installed in oil supply li...

Zusammenfassung:	PURPOSE:To enable improved supply of oil when the compressor is started again by providing a non-return valve in the oil supply line to prevent flow of oil from the fuel supply line to the low pressure area when the compressor is stopped. CONSTITUTION:Non-return valve 8 is installed in oil supply line 6. The body of non- return valve 8 is shaped like a ball. As the valve body moves to outer side pocket section 9 from the center of the oil supply line due to cetrifugal force of the driving axis of an electric motor while the compressor is operating, oil line 7 is kept open. When compressor stops, however, said centrifugal force is lost and said valve body returns to the center of said oil supply line closing the line to prevent the flow of oil. Sufficient oil remains in an oil basin 10 assuring adequate oil supply when the compressor is restarted.
