REFRIGERATING CYCLE DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately detect the amount of a refrigerant by a flow sensor 15. SOLUTION: A compressing portion 11 compressing the refrigerant by a driving force of a vehicle engine 4 is disposed in a housing of a compressor 1. The flow sensor 15 is disposed to detect a flow rate of the refrigerant discharged from the compressing portion 1. The flow sensor 15 comprises a throttle 15b and a pressure difference detecting mechanism 15a. The throttle 15b throttles the flow rate of the refrigerant discharged from the compressing portion 11. The pressure difference detecting mechanism 15a detects the flow rate of the refrigerant discharged from the compressing portion 11 by detecting the pressure difference between the refrigerant upstream side and the refrigerant downstream side of the throttle 15b. An oil separator 12 for separating lubrication oil from the refrigerant discharged from the compressing portion 11 is disposed between the compressing portion 11 and the flow sensor 15.
