Abstract
In a scroll fluid discharging apparatus including a stationary scroll and a revolving scroll, each of the mutually engaging laps and of these scrolls and each has a first lap portion without a tip seal in contact with the mirror-finished opposed scroll surface, thus providing an empty tip seal groove space, the first lap portion covering a predetermined lap length from the edge of the lap on the peripheral side thereof toward the central side. Each of the mutually engaging laps of the scroll also has a second lap portion with a tip seal in contact with the mirror-finished opposed scroll surface, the second lap portion having the remaining lap range from the first lap portion being neighboring each other up to the central side lap edge. Compressed fluid is discharged under a higher discharge pressure than in the prior art with the same drive motor rating and at the same motor rpm as in the prior art.
