Abstract
PURPOSE:To increase the compression ratio with a simple arrangement by forming a through-hole in a spiral member in a stationary blade, and by forming a groove in a mirror plate in a movable blade at a position facing the through-hole so that a compression chamber may be communicated with another chamber through the hole and the groove in a short time. CONSTITUTION:A scroll compressor is composed of stationary and movable blades 1, 2. Further, a compression chamber 7 is formed between the stationary blade 1 and the movable blades 2. Further, the stationary blade 1 is formed therein with a center opening 8 through which compressed fluid is discharged. In this arrangement, a spiral member 3 in the stationary blade 1 is formed therein with a through-hole 4 in parallel with the axial direction of the spiral member 3. Meanwhile, the bottom surface 5 of a mirror plate in the movable blade 2 is formed therein with a groove 6 facing the through-hole 4. Further, the hole 4 is communicated with the groove 6, and high pressure gas is introduced selectively and respectively into and outside of the compression chamber 7 when a part of the groove 6 comes to positions inside and outside of the spiral member 3, respectively, so as to inject the fluid. With this arrangement, the compression chamber 7 is communicated with another chamber in a short time so as to increase the compression ratio.
