定流量スピードコントローラ。[Claims for Utility Model Registration] In a speed controller that allows fluid to pass through a flow path provided inside a cylindrical main body as a free flow in one direction and as a controlled flow with a controlled flow rate in the opposite direction, The flow path extends through the main body in the axial direction, and a control hole of a predetermined size is provided in the center to allow the control flow to pass through at a predetermined flow rate.
A control body formed to allow the free flow to pass between an outer wall surface and an inner wall surface of the flow channel is fixed within the flow channel, has a cone shape, and has an inner circumferential surface that is air-liquid tight to the control body. When the control flow passes through the flow channel, the outer periphery is in close contact with the inner wall surface of the flow channel in a gas-liquid tight manner so that the control flow passes through the control hole. A diaphragm is provided so that the outer peripheral edge separates from the inner wall surface of the flow channel when the free flow passes through the channel, allowing the free flow to pass between the control body and the inner wall surface of the flow channel, and one of the main bodies Or a constant flow rate speed controller characterized by having fittings for tube connection provided at both ends.
