Abstract

The drive shaft (18) includes an upper recess formed in an upper end portion (21) of the drive shaft (18) and including a cylindrical mounting portion (23) eccentrically arranged in relation to a rotational axis (A) of the drive shaft (18), the cylindrical mounting portion (23) having a cylindrical wall surface and being designated to receive a pin element (16) protruding from an orbiting scroll base plate (13); and a radial groove (37) formed in the cylindrical wall surface of the cylindrical mounting portion (23) and extending over a circumferential section thereof, the radial groove (37) being configured to be supplied with oil from an oil sump (35) of the hermetic scroll compressor (1) during rotation of the drive shaft (18), a radial inner surface of the radial groove (37) intersecting with the cylindrical wall surface at a predetermined circumferential position, to ensure lubrication of a bearing surface for the pin element (16) during rotation of the drive shaft (18).
