SCROLL COMPRESSOR

PROBLEM TO BE SOLVED: To provide a scroll compressor capable of suppressing the deterioration in the efficiency of volume due to leakage of coolant from an ejection pressure space to a suction pressure space because the leakage of the coolant from the ejection pressure space to the suction pressure space due to the backflow operation increases although an over compression loss can be reduced when a groove for communicating a compression chamber with a fixed scroll ejection port is disposed on an orbiting scroll.SOLUTION: A fixed scroll has the ejection port which ejects the coolant existing in the compression chamber, the orbiting scroll has the groove which communicates the ejection port with the compression chamber, a first compression chamber is formed on an inner line side of a wrap of the orbiting scroll and, before the groove is communicated with both of the first compression chamber and the ejection port, a second compression chamber is formed on the inner line side of the wrap of the orbiting scroll.
