Scroll compressor with mechanically actuated capacity control |
摘要 |
A scroll-type compressor for realizing the operating condition of complete 0% capacity without using an electromagnetic clutch. In order to minimize the power loss, a compliance crankshaft mechanism for allowing the orbiting radius of the movable scroll member to change steplessly to zero is interposed between a shaft and a scroll member. A guide hole having an inclined surface such as a two-step conical surface is formed at the end plate of the movable scroll member. A plunger adapted to engage by advancing toward and retracting from the guide hole is supported on a housing. When the plunger is advanced into the guide hole under the control of a control operation device including a control pressure chamber and a control valve, the movable scroll member moves radially, so that the amount of eccentricity and the orbiting radius thereof are reduced to achieve the 0% capacity.
