Title:
PISTON TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JP2021032200
Kind Code:
A
Abstract:
To provide a piston type compressor capable of suppressing power losses.SOLUTION: A compressor is equipped with a drive shaft 3, a movable body 10 and the like. The drive shaft 3 has a shaft path 33, a first path 35, and a second path 37. The shaft path 33 extends in a driving axis O direction. The first path 35 extends in a diametrical direction of the drive shaft 3, and communicates with the shaft path 33 and a swash place chamber 31. The second path 37 communicates with the shaft path 33 and extends in the diametrical direction of the drive shaft 3. The second path 37 intermittently communicates with front side communication paths 24a to 24e with the rotations of the drive shaft 3. The movable body 10 has a first movable body 11 and a second movable body 12. The second movable body 12 has a cover body 12b. The cover body 12b maximizes a communication of the second path 37 and the front side communication paths 24a to 24e when a discharge flow rate is the maximum, and on the other hand, minimizes the communication area of the second path 37 and the front side communication paths 24a to 24e when the discharge flow rate is the minimum.SELECTED DRAWING: Figure 1
