Document Type and Number:
WIPO Patent Application WO/2017/159393
Kind Code:
A1
Abstract:
Provided is a scroll compressor with which frictional force between the scrolls is reduced without inducing compression defects. This scroll compressor is equipped with a compression mechanism 4 comprising a fixed scroll 21 and a movable scroll 22, and compresses a refrigerant in a compression chamber 34 formed between the laps 24, 32 of the two scrolls as the movable scroll undergoes orbital rotation. In addition, a back pressure chamber 39, which is formed on the back surface of the movable scroll, and a connecting hole 48, which is opened and closed by the movable scroll and which connects the back pressure chamber and a suction part 37, are provided. The connecting hole connects the back pressure chamber and the suction part at an angle that is delayed by a prescribed rotational angle from the designed discharge completion process of the compression mechanism.
