摘要： A wet type sliding apparatus in which a multilayer sliding member is used in the presence of a lubricating oil, characterized in that the multilayer sliding member is composed of (1) a backing metal layer, (2) a porous, sintered layer provided thereon and (3) a surface layer consisting essentially of polyetheretherketone formed by impregnating and coating the porous, sintered layer with a sliding resin consisting essentially of polyetheretherketone. The above sliding member has a small friction coefficient and excellent wear resistance. In particular, the sliding noise can be more effectively inhibited by adjusting the face roughness of the surface layer of the sliding member to 2 .mu.m or less.

摘要： An Oldham ring of a scroll type compressor having a swivel scroll of aluminum alloy. The Oldham ring is of cast aluminum alloy and has a pair of projections (a) serving to engage with a pair of guide grooves formed in a surface of the swivel scroll adjacent to a crankshaft. Sliding surfaces of the projections which are to be brought into contact with inner surfaces of the guide grooves are each covered with a metal sheet made of a metal which is different from aluminum and aluminum alloys. It is recommended that the metal sheet has the following thickness (t): t=0.5-2.5 mm, T/20.ltoreq.t.ltoreq.T/4 (where, T represents the widthwise dimension of the projection in the circumferential direction of the Oldham ring). The metal sheet is united with the Oldham ring by insert casting.
