    摘要： The invention is applied to a compressor comprising: a cylinder block (10) provided with a radial bearing (11) and an axial bearing (12); an eccentric shaft (20) having an upper end extension (21 ), around which a rotor (30) is mounted and supported on the axial bearing (12). A sliding ring (40) is mounted around said upper end extension (21), which is provided with an indexing means (22) to which is coupled a positioning means (42) of the sliding ring (40), rotatively locking the latter to the eccentric shaft (20). The mounting process comprises the steps of: mounting the eccentric shaft (20) in the radial bearing (11); descendingly mounting the sliding ring (40) around the upper end extension (21) of the eccentric shaft (20), until reaching an axial positioning stop (22c) therein, rotationally locking the sliding ring (40) to the eccentric shaft (20); and mounting the rotor (30) to the eccentric shaft (20) until seating a lower face portion (32) of the rotor (30) on the sliding ring (40).

    摘要： A hermetic compressor, comprises: a hermetic shell (1); a cylinder block (2) defining, a shell portion (Ia) and a compression cylinder (3) having an end (3a) opened to the exterior of the hermetic shell (1) and closed by a valve plate (5); a head (6) affixed to the cylinder block (2), over the valve plate (5) so as to define, with the latter, at least one discharge chamber (10). The cylinder block (2) incorporates a tubular projection (20) surrounding the valve plate (5) and at least part of the head (6). An outer cover (30) is hermetically affixed to the tubular projection (20) for defining therewith a discharge plenum (31) in fluid communication with the discharge chamber (10), the tubular projection (20) or the outer cover (30) being provided with a refrigerant gas outlet (40) opened to the exterior of the hermetic shell (1).

    摘要： The arrangement is applied to a reciprocating compressor comprising: a reciprocating piston (10); and a driving rod (9, 40) having one end (9c, 41) coupled to a driving means (DM) and an opposite end (9b, 42) cooperating with a joint pin (50) mounted to the piston (10), and carrying one coupling longitudinal extension (43) fitted in the joint pin (50) and there retained so that the driving rod (40) displaces the piston (10) in its suction stroke. The joint pin (50) is coupled to the piston (10) during the compression stroke along a longitudinal extension of the side surface of the joint pin (50) larger than the difference between the total longitudinal extension of the latter and the height of the opposite end (42) of the driving rod (40).
