<p>A temperature responsive fluid control valve with sequential control functions, employing a pair of axially aligned hollow elongated plungers or slide pins, and a pair of ball valves and valve seats therefor. One ball valve is straddled by the two plungers, being biased onto its seat by the second plunger and shiftable off its seat by the first plunger. This ball valve controls a first fluid flow in response to a thermoresponsive sensor acting on the first plunger. The second ball valve is operated sequentially after the first, via the second plunger for control of a second sequential fluid flow using the same thermoresponsive sensor.</p> |
