Title:
【発明の名称】スクロール型圧縮機
Document Type and Number:
Japanese Patent JP3369786
Kind Code:
B2
Abstract:
A scroll type fluid displacement apparatus includes a first and a second scroll, each having an end plate and a spiral wrap extending from one side of the end plate. The spiral wraps interfit at an angular and radial offset to make a plurality of line contacts which define a pair of fluid pockets. A driving mechanism is operatively connected to the first scroll to orbit the first scroll relative to the second scroll while preventing rotation of second scroll to thereby change the volume of fluid pockets. Sealing elements are disposed in the axial end of the spiral wraps for sealing a central portion of fluid pocket defined by the spiral wraps. Thus, the axial sealing of fluid pocket formed between the orbiting and fixed scroll is more secured in all process from the suction to the discharge stage. Further, the volumetric efficiency of the compressor increases.
