Document Type and Number:
WIPO Patent Application WO/2016/098822
Kind Code:
A1
Abstract:
[Problem] The objective of the present invention is to provide a variable capacity compressor with which the startup performance of the compressor can be improved, with which it is possible to reduce the amount of refrigerant that circulates internally during an intermediate stroke, and with which it is possible to eliminate the risk that contaminants or the like in the refrigerant will render it impossible to control the compressor.
[Solution] This variable capacity compressor is provided with: an open passage 50 which communicates with a control pressure chamber 4 and a suction intake chamber 33; and a valve accommodating chamber 51 formed in the open passage. The open passage 50 has a configuration comprising: an upstream side open passage 50a communicating with the control pressure chamber 4 and the valve accommodating chamber 51, and a downstream side open passage 51b communicating with the valve accommodating chamber 51 and the suction intake chamber 33. The variable capacity compressor is provided with: a valve body 52 accommodated in the valve accommodating chamber 51 in such a way as to open and close the downstream side open passage 50b; an urging means (spring 53) which urges the valve body 52 in a direction opening the downstream side open passage 50b; a discharging pressure introduction passage 54 which communicates with the valve accommodating chamber 51 and a discharge chamber; and a non-return valve 55 which is provided in the upstream side open passage 50a and which allows fluid to flow only from the control pressure chamber 4 to the valve accommodating chamber 51.
