Abstract:
A scroll compressor includes a first chamfered portion formed at a distal end portion 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.
