Abstract

The present invention discloses an apparatus for varying a capacity of a scroll compressor. The apparatus comprises: a pressure control mechanism for controlling a pressure applied to the back of a orbiting scroll orbiting engaged with a fixed scroll; and a sealing varying mechanism for changing a sealing region of a orbiting scroll wrap and a sealing region of a fixed scroll wrap according to a change in the pressure applied to the back of the orbiting scroll. By this, the capacity of a refrigerant compressed by the fixed scroll and orbiting scroll using a high pressure in a casing can be varied to thus minimize the power consumption.
