Thermostatic valve device having non-linear flow characteristics |
摘要 |
A thermally responsive valve device having non-linear flow characteristics. The valve device is particularly adapted to control fluid flow in an automotive coolant system. The thermally responsive valve device includes movable and stationary valve structure. A movable valve member is movable to create a flow passage and to adjust the open area thereof, but movement of the movable valve member provides a non-linear relationship between the area of the flow passage created and the distance of travel of the movable valve member. The stationary valve member is provided with a valve seat having a sloping encompassng wall so that with slight opening movement of the movable closure member a very limited volume of fluid flow is permitted. As the movable valve member continues to move in an opening direction, the non-linear relationship between the distance of movement of the movable valve member and the flow area created continues. The fluid flow gradually increases until a specific maximum flow rate is achieved. This operating characteristic eliminates or dramatically reduces temperature fluctuations in the coolant system.
