Title: Scroll type fluid machinery
Inventor: IKEGAWA MASATO
IPC: F04C18/02
Filed: 1985-01-25
Abstract: PURPOSE:To reduce the suction resistance of a scroll compressor and increase cooling efficiency by forming a passage which leads from the surface on the lap- part side to the surface on the reverse-lap-part side onto the mirror plate of a swirl scroll and inhaling gas from a compression chamber side from the above- described passage. CONSTITUTION:A discharge port 3 is formed in the center part of the mirror plate 2b of a fixed scroll 2, and a suction port 4 is formed onto the outer periphery side of a swirl scroll 1. Gas flows into the space 11 inside a housing 10 from a port 19 formed onto the housing 10, and flows on the circumference of a driving part and the swirl scroll mirror plate 1b, cooling the members. The gas is inhaled into a compression chamber through the suction port 4. Therefore, the distance from the space inside the housing to the suction passage leading to the compression chamber is made shortest, and the suction resistance of the compressor can be reduced.
