PROBLEM TO BE SOLVED: To suppress a discharge loss of a fluid passing through a discharge port while suppressing sealing failure of a cylinder chamber regarding an oscillating piston type compressor.SOLUTION: A piston (40) includes: a low pressure intersection part (2b) in which an outer circumferential surface (4) of a piston (40) intersects with a side surface (5b) at a low-pressure chamber (45b) side regarding a blade (41); and a high pressure intersection part (2a) in which the outer circumferential surface (4) of the piston (40) intersects with a side surface (5a) at a high-pressure chamber (45a) side regarding the blade (41). The piston (40) comprises a shape in which the high pressure intersection part (2a) is more shifted to the distal end side of the blade (41) than low pressure intersection (2b). |
