Self-sealing mechanism for scroll compressor

A self-sealing mechanism for a scroll compressor is disposed inside a frame of the scroll compressor at a position between a back-pressure chamber and a fixed scroll, including an accommodating space; a groove communicating the space with the chamber; a one-way valve disposed at one end of the space...

Beschreibung
Zusammenfassung:	A self-sealing mechanism for a scroll compressor is disposed inside a frame of the scroll compressor at a position between a back-pressure chamber and a fixed scroll, including an accommodating space; a groove communicating the space with the chamber; a one-way valve disposed at one end of the space adjacent to the groove to maintain communication between the space and the groove in a normally closed state; and a suction port penetrating from the space to an entrance of the fixed scroll. When the pressure of the chamber is increased in an instant, the valve is opened in real time for allowing the lubricating oil inside the chamber to flow into the space, thereby regulating the pressure of the chamber. Moreover, the lubricating oil in the space can be sucked under the suction force from the fixed scroll and fill in positions between the fixed scroll and an orbiting scroll.
