摘要： A mode changing apparatus for a scroll compressor is provided that may include a low-pressure passage that communicates with a suction side formed by an orbiting motion of an orbiting scroll, an intermediate-pressure passage that communicates with an intermediate-pressure side formed by the orbiting motion of the orbiting scroll, a block assembly mounted at the fixed scroll and having a connection channel that connects the low-pressure passage and the intermediate-pressure passage, a switching device disposed at the block assembly that opens/closes the connection channel, and a pressure supply device that selectively applies, to the block assembly, a discharge gas pressure discharged from the fixed and orbiting scrolls and a suction gas pressure sucked into the fixed and orbiting scrolls, to thereby operate the switching device. With such a simplified structure, the gas compression capacity of a scroll compressor may be varied, enhancing energy efficiency of a system.
