Abstract
A pressure relief passage includes a first pressure relief passage and a second pressure relief passage. A pressure relief hole is provided in an upper part of the first pressure relief passage in the direction of gravitational force. The second pressure relief passage merges with the first pressure relief passage to form a merging portion. The cross-sectional flow area of a stagnation portion, which is the maximum cross-sectional flow area of the second pressure relief passage, is smaller than the cross-sectional flow area of a connection passage, which is the minimum cross-sectional flow area of the first pressure relief passage.
