Abstract

PURPOSE: To lower injection pressure and improve refrigeration capacity by a method wherein an injection hole is provided in such a manner that it opens before a roller which makes eccentric rotation comes to the position of rotational angle to close a suction hole.
CONSTITUTION: Cylinder 21 is provided with suction hole 25 and discharge hole 26 with blade 24 as their boundary, and roller 22 makes eccentric rotation inside cylinder 21. Injection hole 27a is provided at the position at which it is caused to shift from a closed state to an open state by roller 22 when it comes at the position so that its axis lies on the center line of blade 24. The position of rotational angle (X axis in the drawing) of roller 22 when injection hole 27a opens lies on the side of counter-clockwise direction from the position of rotational angle (Z axis in the drawing) of roller 22 when suction hole 25 is closed. By this, when the amount of injection is fixed, it is possible to lower injection pressure and increase refrigerating capacity.
