摘要： The fixation arrangement of the present invention is applied to a compressor of the type which comprises a shell (1) inferiorly defining an oil sump (3) and housing: a crankshaft (4) journalled in a cylinder block (2) and carrying a rotor (6) formed by a stack of annular laminations; and an oil pump (10) comprising a tubular sleeve (20), which is superiorly mounted to the rotor (6) and inferiorly immersed in the oil sump (3), and a pump shaft (30). The fixation arrangement comprises at least one retention element (40) radially and axially locked around the tubular sleeve (20) and having a radially outer locking portion (41), which is seated and radially forced against a respective confronting circumferential extension (6c) defined between two consecutive annular laminations, in order to axially lock the tubular sleeve (20) to the rotor (6).

摘要： The refrigeration compressor includes a cylinder block carrying a crankshaft and a stator of an electric motor, whose rotor is mounted to the crankshaft; and an oil pump presenting: a tubular sleeve affixed to the crankshaft or to the rotor and having a pump body internal to the tubular sleeve and carried by the cylinder block or by the stator. A fixation rod is superiorly articulated to the cylinder block or to the stator and has a lower portion angularly and freely displaced orthogonally to the articulation axis and around which the lower end portion of the pump body is axially retained and slidably mounted, orthogonally and coplanar to the rotation axis of the rotor. The tubular sleeve is provided with an upper tubular portion having a circumferential groove, which fits and retains, rotationally and axially, a tubular metallic connector telescopically mounted and retained to the rotor or to the crankshaft.
