SCROLL COMPRESSOR
First Claim
1. A scroll compressor, comprising:
- a fixed scroll including a first base plate portion and a first spiral blade provided to stand on one surface of the first base plate portion;
an orbiting scroll including a second base plate portion and a second spiral blade provided to stand on a surface of the second base plate portion opposite to the fixed scroll, and is configured to perform an orbiting motion with respect to the fixed scroll, the first spiral blade and the second spiral blade being in mesh with each other to form a compression chamber;
a first chamfered portion formed at each of both corner portions of a distal end portion of the first spiral blade;
a second chamfered portion formed at each of both corner portions of a distal end portion of the second spiral blade;
a third chamfered portion formed on each of both sides of a bottom portion of the first spiral blade, the third chamfered portion having a same shape as a shape of the second chamfered portion; and
a fourth chamfered portion formed on each of both sides of a bottom portion of the second spiral blade, the fourth chamfered portion having a same shape as a shape of the first chamfered portion,a chamfer dimension of the first chamfered portion and a chamfer dimension of the second chamfered portion being different from each other.

Abstract
A scroll compressor includes a first chamfered portion formed at a distal end potion of a spiral blade of a fixed scroll, a second chamfered portion formed at a distal end portion of a spiral blade of an orbiting scroll, a third chamfered portion formed at a bottom portion of the spiral blade of the fixed scroll, and a fourth chamfered portion formed at a bottom portion of the spiral blade of the orbiting scroll. An expression of 0<{(Av1+Av2)/2}/Ac<1×10−4 is satisfied where a sectional area of a space between the first chamfered portion and the fourth chamfered portion is defined as Av1, a sectional area of a space between the second chamfered portion and the third chamfered portion is defined as Av2, and a sectional area of a compression chamber is defined as Ac.
