Patent Searching and Data


Title:
VOLUME-VARIABLE SWASH PLATE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/145798
Kind Code:
A1
Abstract:
The purpose of the present invention is to make it possible to ensure quietness at small volume while preventing pressure loss in intake pressure at large volume, achieve high volumetric efficiency at small volume without causing an increase in manufacturing cost or a decrease in design freedom, and allow liquid refrigerant and the like that could be filled in a crank chamber upon starting to rapidly flow out so that a volume increase can be rapidly achieved. If the intake pressure Ps is lower than a set intake pressure, and if a crank chamber pressure Pc is higher than a control pressure Pcv in a second air supply passageway 43, a first valve body 65 decreases the opening degree of an intake passageway 51 and a second valve body 67 opens a bleed passageway 52. If the intake pressure Ps is higher than the set intake pressure, and if the crank chamber pressure Pc is higher than the control pressure Pcv, the first valve body 65 increases the opening degree of the intake passageway 51 and the second valve body 67 opens the bleed passageway 52. If the crank chamber pressure Pc is lower than the control pressure Pcv, the first valve body 65 decreases the opening degree of the intake passageway 51 and the second valve body 67 closes the bleed passageway 52.
