摘要
Insufficient oil sealing of a compression chamber leads to insufficient compression of refrigerant, and thereby leads to inefficiency. That is, oil sealing is an issue from the viewpoint of improvements in efficiency. To solve this, a back pressure control valve is disposed at a position where intermittent communication starts when both the volume of a suction chamber adjacent to the inner line of an orbiting scroll and that adjacent to the outer line of the orbiting scroll are increased. Moreover, oil is supplied to the compression chambers through a space formed at a position deeper than the tooth root of the fixed scroll for tooth tip lubrication.
