Claims

[Scope of utility model registration request]

A rotor that rotates in a fixed position and has a cam surface on the circumference of one end that changes in the direction of the rotation axis, and the rotor is loosely inserted to form a sealed chamber between the cam surface and the cam surface. A cylinder that forms an inlet port and a discharge port that open to a sealed chamber; and a cylinder that is disposed at a position that partitions the sealed chamber between the inlet port and the discharge port, and is slidably held in the direction in which the cam surface changes. 1. A fluid compression machine, comprising: a vane that presses the vane against the cam surface;
