Document Type and Number:
WIPO Patent Application WO/2017/208785
Kind Code:
A1
Abstract:
Provided is a valve device in which more small holes can be provided to a valve body, and with which the flow rate of a fluid can be finely adjusted even when a small valve body is used. Specifically, this valve device is provided with a valve body driving member (50) turned by driving force from a drive source (60), and a valve body (20) that turns in a circumferential direction integrally with the valve body driving member. Fitting parts (251-253, 551-553) that are fitted together are formed in the lower surface of the valve body driving member and the upper surface of the valve body. The valve body has hole parts (211-215) formed therethrough in the axial direction thereof. Groove parts (211f-215f) serving as flow channels leading from the outer peripheral surface of the valve body to the hole parts are formed in the upper surface of the valve body. The fitting parts and the groove parts on the valve-body side have connecting parts (271, 272, 274, 275), which are portions where the upper surface of the valve body is formed continuously with other elements constituting the valve body without separating from said elements.
