Abstract (en)

[origin: EP1074737A2] A single-head swash-plate refrigerant compressor of fixed displacement type is disclosed which can prevent lock-up due to burning between the spherical seat surface of the pistons and the spherical surface of the shoes and prevent plastic deformation of the pistons. A lubrication layer 6b coated with tin by electroless plating is formed between the spherical seat surface 6a of the piston 6 and the spherical surface 8a of the shoe 8 in order to improve the slidability therebetween. <IMAGE>
