Abstract
Shoes for operatively connecting a swash-plate with the compression pistons of a swash-plate type compressor are made from a novel Cu-based alloy. Improved shoes are characterized by a combination of high heat conductivity and excellent wear resistance properties particularly when subjected to a lubricating condition so severe that no lubricating oil is supplied to the surface of the shoes at the initial period of the compressor operation. Phosphorus and elements of C group (Pb and/or Sn), as well as elements of A group (Mn and Si) and/or B group (the IVb and VIb groups of the periodic table), are added in predetermined amounts to the Cu-based alloy, so that the properties mentioned above are simultaneously obtained. The compressor according to the present invention can be reliably employed, without the occurrence of seizure over a long operational period for air-conditioning vehicles, in which the sliding condition of the shoes is drastically varied with the rotation of the engine.
