Latest Patents
Maruyama's latest patents include a wet type sliding apparatus and an Oldham ring for a scroll type compressor. The wet type sliding apparatus utilizes a multilayer sliding member composed of a backing metal layer, a porous sintered layer, and a surface layer made of polyetheretherketone. This design results in a low friction coefficient and excellent wear resistance, effectively reducing sliding noise by adjusting the face roughness of the surface layer to 2 micrometers or less. The Oldham ring, designed for a swivel scroll of aluminum alloy, features a cast aluminum alloy construction with projections that engage with guide grooves. The sliding surfaces of these projections are covered with a metal sheet made from a different material than aluminum, enhancing durability and performance.
