Title:
ELECTRIC EXPANSION VALVE AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/080066
Kind Code:
A1
Abstract:
This electric expansion valve comprises a driving part (10), an output shaft (44), a body part (60), a valve body (41), and a joint part (50). The driving part receives a supply of electricity, and generates a driving force. The output shaft rotates about the axis due to the driving force output from the driving part, and is translationally displaced along with the rotation. The body part has a first inflow/outflow port (64), a second inflow/outflow port (65), a valve chamber (62), and a valve seat (63). A refrigerant of a refrigeration cycle flows into and out of the first inflow/outflow port. The second inflow/outflow port is formed at a position different from the first inflow/outflow port. The valve chamber is disposed in the middle of a refrigerant passage (66) connecting the first inflow/outflow port and the second inflow-outflow port. The valve seat is disposed inside the valve chamber. The valve body is disposed inside the valve chamber so as to be able to open and close an opening of the valve seat. The joint part connects an end of the output shaft and the valve body so as to be integrally displaceable.
