PURPOSE: To lubricate the sliding face between a slipper and thrust bearing and cam plate smoothly, by providing a refrigerant suction port in a shaft while feeding refrigerant through cam plate and thrust bearing into a cylinder bore.
CONSTITUTION: The refrigerant suction port is formed with a through-hole 22 made along the central axis of shaft 2 while extending to the position provided with a cam plate 7 and thrust bearing 15. Refrigerant gas fed into the shaft 2 will pass through a small hole 25 for thrust bearing 15 to the thrust bearing 25 while through a small hole 26 for cam plate 7 to the front/rear faces of cam plate 7 and fed into the cylinder bore 3. Since sufficient amount of refrigerant gas containing lubricant is fed continuously to the thrust bearing 15 and cam plate 7 and sucked into the cylinder bore 3 deterioration of durability due to insufficient lubrication of sliding face between thrust bearing 15, cam plate 7 and slipper 8 is prevented.
