20090246057 | SCROLL COMPRESSOR - There is disclosed a scroll compressor having an object of stabilizing the moving of an orbit scroll while suppressing the start load of the scroll compressor. In the scroll compressor, a slide bush having a slide face forming a predetermined angle with respect to the direction of gas load of a gas in a compression chamber is interposed on an eccentric shaft of a shaft for driving the orbit scroll, so that when the load of the gas in the compression chamber is applied, the eccentric amount of the eccentric shaft increases. The scroll compressor includes a spring member interposed between the slide bush and the eccentric shaft and configured to constantly urge the eccentric shaft to decrease the eccentric amount of the eccentric shaft, and this spring member urges the eccentric shaft to press the eccentric shaft onto the slide face of the slide bush. | 10-01-2009 |
20110052437 | SCROLL COMPRESSOR - There is disclosed a scroll compressor which can lower the noise level of a harsh frequency without taking a lot of troubles. In a sealed container, a scroll compression element and an electromotive element are provided. The scroll compression element is constituted of a fixed scroll including a vertically provided spiral lap, and a swingable scroll including a vertically provided spiral lap and swiveled by a rotary shaft of the electromotive element with respect to the fixed scroll. A refrigerant compressed by gradually reducing, from the outside to the inside, a plurality of compression spaces formed by engaging both the laps with each other is discharged to a discharge pressure space in the sealed container. The scroll compressor further includes through holes formed in the fixed scroll to connect the compression spaces to the discharge pressure space, and normally closed relief valves provided in the fixed scroll on the side of the discharge pressure space to open and close the through holes, and the depth dimension of each of the through holes is set to a value corresponding to the wavelength of a noise peak frequency. | 03-03-2011 |
