<p>PURPOSE:To prevent seizure by guaranteeing emergency self-supply in the base of lubricating oil supply shortage from outside being generated at the time of supplying lubricating oil between a rotary sliding body and a slided body, and prevent the unnecessary increase of driving force by keeping an emergency self-supply means from interfering with the oil film formation of lubricating oil at the normal reset time. CONSTITUTION:A gap between a sliding element (slided body) 8 and a cam plate (rotary sliding body) 2 rotated together with the rotary shaft 45 of a cam plate type compressor is lubricated by lubricating oil in refrigerant returned to a cam plate chamber. The cam plate 2 is formed of a porous sintered alloy. Lubricating oil is impregnated into holes 2C in the cam plate 2, and the holes 2c facing the surface of the outer surface 2a are sealed by filling-up in grinding or the like. The surface 2a is made into the sliding face, and unsealed holes are left on the inner surface 2b on the inner side of the sliding face 2a. With this constitution, the sliding face 2a is hardly provided with oil absorptivity, and oil impregnation and seepage are switched on the man-sliding face 2b according to the relation with pressure.</p> |
