Capacity-variable rotary compressor

A capacity-variable rotary compressor, in which a vane can be restricted by a pressure difference generated between both side surfaces of the vane when the compressor performs a saving driving, and simultaneously be restricted rapidly and stably by rapidly decreasing a pressure of a vane chamber by...

Beschreibung
Zusammenfassung:	A capacity-variable rotary compressor, in which a vane can be restricted by a pressure difference generated between both side surfaces of the vane when the compressor performs a saving driving, and simultaneously be restricted rapidly and stably by rapidly decreasing a pressure of a vane chamber by leaking a discharge pressure of the vane chamber to an inlet via a low pressure passage and thereby increasing a pressurizing force applied to a side surface of the vane relatively greater than a supporting force applied to a rear surface thereof, whereby the vane can be previously prevented from being vibrated due to a weak restriction force of the vane when a power mode of the compressor is switched into the saving mode, which results in preventing of noise from being increased due to design conditions, thereby enhancing comfortable feeling.
