Title:
VARIABLE-CAPACITY SWASH PLATE-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/017917
Kind Code:
A1
Abstract:
The present invention relates to a variable-capacity swash plate-type compressor comprising: a casing; a rotating shaft; a swash plate; a piston; and an inclination adjustment device comprising a first channel through which a discharge chamber communicates with a crank chamber so as to adjust the inclination angle of the swash plate, and a second channel through which the crank chamber communicates with an intake chamber. The second channel has an orifice hole formed therein so as to reduce the pressure of a fluid passing through the second channel, and has an orifice adjustment device formed therein so as to adjust the effective flow sectional area of the orifice hole. The orifice hole and the orifice adjustment device may be formed such that, if the pressure difference between the pressure in the crank chamber and the pressure in the intake chamber increases, the effective flow sectional area changes from zero (0) to a first area larger than zero (0) and, if the pressure difference further increases, the effective flow sectional area becomes a second area larger than zero (0) and smaller than the first area. Accordingly, quick adjustment of the amount of discharged refrigerant and prevention of degradation of the compressor efficiency can be accomplished simultaneously. In addition, time necessary to switch to a maximum mode can be reduced.
