ROTARY COMPRESSOR
First Claim
1. A rotary compressor, comprising:
- a sealed longitudinal compressor housing which is provided with a discharge portion of a refrigerant at an upper portion thereof, is provided with an inlet portion of a refrigerant at a lower portion thereof, and in which lubricant oil is stored;
a compressing unit which is disposed in the compressor housing, compresses a refrigerant sucked from the inlet portion and discharges the refrigerant from the discharge portion;
a motor which is disposed in the compressor housing and drives the compressing unit via a rotation shaft; and
an accumulator which is attached to a side portion of the compressor housing and is connected to the inlet portion of the refrigerant,wherein when an inner diameter of a cylinder constituting the compressing unit is referred to as Dc, a height of the cylinder is referred to as Hc, and an eccentric amount of an eccentric portion of the rotation shaft is referred to as e, Dc, Hc, and e are set so that a value obtained by an expression (e+Hc)·

Abstract
A rotary compressor includes a sealed longitudinal compressor housing which is provided with a discharge portion of a refrigerant at an upper portion thereof, is provided with an inlet portion of a refrigerant at a lower portion thereof, and in which lubricant oil is stored; a compressing unit which is disposed in the compressor housing, compresses a refrigerant sucked from the inlet portion and discharges the refrigerant from the discharge portion; a motor which is disposed in the compressor housing and drives the compressing unit via a rotation shaft; and an accumulator which is attached to a side portion of the compressor housing and is connected to the inlet portion of the refrigerant. When an inner diameter of a cylinder constituting the compressing unit is referred to as Dc, a height of the cylinder is referred to as Hc, and an eccentric amount of an eccentric portion of the rotation shaft is referred to as e, Dc, Hc, and e are set so that a value obtained by an expression (e+Hc)·(Dc−e)1/3/(e·Hc)2/3 is less than 4.1.
