摘要 PCT No. PCT/BR93/00025 Sec. 371 Date Jul. 25, 1994 Sec. 102(e) Date Jul. 25, 1994 PCT Filed Aug. 10, 1993 PCT Pub. No. WO94/04853 PCT Pub. Date Mar. 3, 1994.The assembly is used in a reciprocating hermetic compressor of the type comprising a cylinder block (4), presenting a cylinder (11), within which a piston (20) reciprocates, a smaller eye (31) of a connecting rod (30) being introduced into and retained inside said piston (20), through an articulating pin (40), having its end portions supported on respective radial lateral openings of the piston, wherein the portions, which are defined by the peripheral edge of at least one end of the articulating pin and the adjacent internal surface (23a, 24a) of the respective lateral radial opening (23, 24) of the piston (20), are attached to each other by at least one welding spot contained in a respective first welding region, located in a sector of about 90 degrees of said end and symmetric to a diametral line of said end of the articulating pin (40), said line being parallel and coplanar relative the longitudinal axis of the piston (20), at least one welding spot being provided in at least a second welding region opposite said first welding region, relative a diametral line orthogonal to said first diametral line.
