Scroll compressor with bypass holes communicating with an intake chamber

A scroll compressor comprising:

• a first scroll that has a first end plate and a first spiral wall disposed on a surface of the first end plate;
• and
• a second scroll that has a second end plate and a second spiral wall on a surface of the second end plate, the second scroll being supported so as to be revolvable while being prevented from rotating, and the second spiral wall being engaged with the first spiral wall, wherein
• at least one of the first end plate and the second end plate includes a step portion where a height of the surface of at least one of the first end plate and the second end plate is set high on a center side and is set low on an outer end side of a spiral along at least one of the first spiral wall and the second spiral wall,
• at least one of the second spiral wall and the first spiral wall includes a stepped portion where a height of at least one of the second spiral wall and the first spiral wall is set low on the center side and is set high on the outer end side, so that the stepped portion engages the step portion so that a bottom surface of at least one of the first and the second scroll and an edge of at least one of the second spiral wall and the first spiral wall are in contact with each other to form a compression chamber surrounded by the first spiral wall, the second spiral wall, the first end plate and the second end plate,
• an intake chamber is formed in a position around the first scroll,
• the first end plate includes a first bypass hole that is provided in a position between the step portion and a center of the spiral, the first bypass hole communicates the compression chamber with the intake chamber, and
• the first end plate includes a second bypass hole that is provided in a position between the first bypass hole and an outer end of the spiral, the second bypass hole communicates the compression chamber with the intake chamber.
