Title:
ELECTRICALLY OPERATED VALVE
Document Type and Number:
WIPO Patent Application WO/2024/062989
Kind Code:
A1
Abstract:
This electrically operated valve comprises a main body portion (40), a drive portion (10), a holding member (27), and a casing (54). The main body portion internally includes a flow passage (45) through which a fluid flows. The drive portion uses electric power to generate a driving force that moves a valve body (33) for adjusting a flow rate of the fluid flowing through the flow passage. The holding member is attached to an attachment portion (46) formed in one surface of the main body portion. The holding member guides a movement direction of the valve body so as to be directed toward the interior of the flow passage, and positions the valve body and the drive portion. The casing is attached to the main body portion so as to cover the holding member and the drive portion on said one surface side of the main body portion. A stepped portion (47) obtained by causing said one surface of the main body portion to be displaced in a vertical direction is formed around the attachment portion of the main body portion, in a position inward of and adjacent to a part that comes into contact with the casing.
