Title:
DEVICE FOR DETECTING FLUID FLOW
Document Type and Number:
WIPO Patent Application WO/2018/016478
Kind Code:
A1
Abstract:
The present invention enables a valve body to reliably separate from an electrode so as to achieve improvement of reliability in detection of a fluid flow without affecting the return action of the valve body even in the case when the flow rate of a fluid is low. A fluid supply opening 12 and a fluid discharge opening 15 are formed in a main body 10 having a fluid space E through which a fluid can be passed. One electrode Da is disposed so as to have a contact point T, at an opening edge 12a of the supply opening 12 of the main body 10 and/or at a periphery 12b of the opening edge 12a, while another electrode Db is disposed on the main body 10. A guide member 50 made of an insulating material is supplementally provided, the guide member housing a conductor valve body 40 for opening/closing the supply opening 12 and a conductor coil spring 41 for biasing the valve body 40 in which fluid space E is formed so as to be slidable while a flow path is secured for allowing the fluid to flow from the supply opening 12 to the discharge opening 15, the guide member having a receiving surface 51 disposed face to face with one end face of the fluid space E so as to receive the fluid flowing from the supply opening 12, and also having a top surface 52 disposed face to face with the other end face of the fluid space.
