Title:
DISCHARGE DISPLACEMENT CONTROL SYSTEM FOR VARIABLE DISPLACEMENT COMPRESSOR
Document Type and Number:
Japanese Patent JP2016050543
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a discharge displacement control system for variable displacement compressor capable of avoiding its operation under a large discharge displacement at a lack of poor refrigerant by an easy configuration without having any displacement means.SOLUTION: This invention relates to a system for controlling a displacement amount of a variable displacement compressor 100 where a displacement based on a variation of pressure in a control pressure chamber 140 varies comprising a control valve 300 for adjusting an opening degree of a pressure supply passage 145 communicating between a discharging chamber 142 with a control pressure chamber 140 to change a pressure within the control pressure chamber 140; pressure detecting means for detecting a pressure in a low pressure region of a refrigerant circulation circuit; and control current supply means for setting a control current to reduce a displacement when the pressure in the low pressure region in the refrigerant circulation passage is lower than a pre-set lower limit value to supply it to an actuator.SELECTED DRAWING: Figure 1
