AXIAL AND RADIAL SUPPLY BORES IN A SCROLL COMPRESSOR ABSTRACT OF THE DISCLOSURE This invention discloses a lubricating mechanism of a hermeti- cally sealed scroll type compressor in which an inner chamber of a housing is kept at suction pressure. The compressor includes a drive shaft supported by bearings in inner blocks. The drive shaft is opera- tively linked to an orbiting scroll which orbits within a stationary scroll. A rotation prevention device prevents rotation of the orbiting scroll. The drive shaft includes an axial bore extending from an open end and terminating adjacent a forward bearing. A pin extends from the end of the drive shaft to the orbital scroll. A passage links the axial bore to an opening at the end of the pin facing the orbital scroll radial bores are provided near the terminal end of the axial bore and at the rearward end of the axial bore near a rearward bearing. The radial bores link the axial bore to a suction chamber of the compres- sor to allow lubricating oil to lubricate the bearings. The narrow pas- sages allows lubrication of the rotation prevention mechanism. In a second embodiment the suction chamber is divided into two sections by a partition wall. An inclined passage links the two sections to allow the lubricating oil to flow.
