ABSTRACT:
A thermostatic valve for controlling fluid flow from a high-temperature source to a low-temperature source. The thermostatic valve includes a first end which, during use of the valve, is exposed to fluid from the high-temperature source and a second end which, during use of the valve, is exposed to fluid from the low-temperature source. The valve also includes a valve seat member having a valve seat and a valve member having two ends and an exterior closure surface registrable with the valve seat. The valve member has a shape, except at its two ends, with only curves of greater than about 150.degree., so that fluid flowing past the valve member is caused to make only turns of less than about 30.degree.. The thermostatic valve is useful for controlling coolant flow from an internal combustion engine block to a radiator. The valve member may have a shape formed of continuously-varying parabolic curves. The valve may further include an expansible-material housing, containing expansible material, at the first end of the valve. The expansible-material housing may be conical and pointed at the end facing the engine block.
