Title:
SINGLE SCREW COMPRESSOR AND REFRIGERATION CYCLE DEVICE WITH SAID SINGLE SCREW COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/102615
Kind Code:
A1
Abstract:
This single screw compressor is provided with an affixation section for affixing the tooth section of a gate rotor and a gate rotor support. The affixation section is provided with a fitting section which is provided to the tooth section of the gate rotor, and a recess which is formed in a contact surface of the gate rotor support and into which the fitting section is fitted. The linear expansion coefficient of the fitting section is higher than that of the gate rotor support, and the thermal expansion of the fitting section caused by an increase in temperature during operation causes the fitting section to come into contact with and be fitted in the recess.
