Title:
ROTARY COMPRESSOR
Document Type and Number:
Japanese Patent JP2020002842
Kind Code:
A
Abstract:
To solve a problem that in a conventional rotary compressor, although a front head and a rear head are bolted to a cylinder, an old design policy is often adopted as it is for a bolt, the size of the bolt may be larger than necessary, and the number of bolts may be large.SOLUTION: A rotary compressor includes a casing 10, a cylinder 33, a first member 31, a second member 32, a first bolt group b1, and a second bolt group b2. The first bolt group b1 fastens the cylinder 33 and the first member 31. The second bolt group b2 fastens the cylinder 33 and the second member 32. The static friction force between the cylinder 33 and the first member 31, which are fastened by the first bolt group b1, is larger than the static friction force between the cylinder 33 and the second member 32, which are fastened by the second bolt group b2.SELECTED DRAWING: Figure 4
