Title:

SCROLL COMPRESSOR AND REFRIGERATION CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/126106

Kind Code:

A1

Abstract:

In order to provide a high-efficiency scroll compressor and a refrigeration cycle device capable of suppressing the outflow of an injection refrigerant to an oil reservoir, capable of suppressing a reduction in reliability due a reduction in the viscosity of refrigerant oil accumulated in the oil reservoir, and capable of suppressing a reduction in performance due to compression of dead volume, injection ports are provided on the base plate of the stationary scroll, which, during the entire rotational phase of the rotational axis, is farther inside than the outermost surface of the structural portion wherein both spiral bodies of the compression mechanism unit are combined, and the injection ports open only into the intake chambers.
