Claims

[Claims for Utility Model Registration] 1. A valve body having a viscous oil storage chamber and a viscous oil outlet, connected to a bimetallic thermostat, rotatably attached to the valve body, and normally connected to the viscous oil outlet. The bimetallic metal is located in a position that covers the
a slide valve that is rotated by a thermostat to open the viscous oil outlet; a coupling that is rotationally driven by an engine and has a first protrusion on one end surface of a disc-shaped portion provided with a viscous oil introduction hole; A cover part that is integrated with the valve body and supported by the coupling via a bearing, and has a second protrusion that forms a labyrinth between the second protrusion and the first protrusion. - a fan coupling ten patrol consisting of a moving part, the viscous oil outlet of the valve body radially with respect to the center of rotation of the slide valve and within the width of the slide valve in the direction of rotation; A plurality of viscous oil introduction holes of the coupling are provided so that the distances from the rotation center become smaller in the rotation direction by sequentially shifting the positions, and the viscous oil introduction hole of the coupling is connected to the rotation center of the slide valve. ) A fan coupling characterized in that a plurality of fan couplings are provided in a radial manner, and a labyrinth formed by the first protrusion and the second protrusion is formed in an annular shape in a range that covers the plurality of viscous oil introduction holes.・Ten Patrol. 2. A fan coupling ten patrol in which the giant labyrinth is formed by first and second protrusions with different pitches on the outer and inner sides. 3 Either one of the first and second projections is provided on a slope that becomes thicker from the inner circumference side to the outer circumference side, and both the first and second protrusions are provided on a slope that becomes thicker from the inner circumference side to the outer circumference side. The fan couplings are formed in such a way that they become progressively lower.
