PURPOSE:To prevent the generation of an abnormal high pressure and the damage of a scroll body due to the generation of the same by a method wherein an eccentricity of a rotary scroll member is decreased when the rotary scroll member is in a condition contacting with a fixed scroll member. CONSTITUTION:The resultant force of the Fg2 of gas in a compression chamber C, which is pushing a rotary scroll member 12, and the force Fg2 of an eccentric shaft 8, which is pushing the rotary scroll member 12, is the force Fo2. The resultant force Fo2 effects into the direction of decreasing the eccentricity (e) of the rotary scroll member 12. Accordingly, the rotary scroll member 12 is separated from a fixed scroll member 17 and liquid, enclosed in the compression chamber C, may escape to the sides of suction and delivery and prevents the generation of the abnormal high pressure, therefore, the damage of the scroll body may be prevented. |
