Patent ID: 8690072

Claim:
A valve for use with a fluid, said valve comprising: a valve body having a pair of spaced-apart flow ports, said valve body including a tubular structure having a side wall and an open end, the tubular structure defining a first subchamber on the inside of the tubular structure in fluid communication with one of the flow ports and the wall having a wall opening therethrough; and defining a second subchamber in fluid communication with the other of the flow ports, the second subchamber extending around the side wall and extending beyond the open end to further fluidly communicate with the open end and the wall opening, a plug having a plug opening and being mounted to the tubular structure for telescopic movement between a first position and a second position wherein: at the second position, the plug is disposed at least in part in the second subchamber and the valve defines: a first flow path between the flow ports through the wall opening; and a second flow path between the flow ports through the open end of the tubular structure and the plug opening; and at the first position, the plug and tubular structure interact to restrict flow through the first flow path and the second flow path; and an actuator for moving the plug between the first position and the second position in response to the temperature of the fluid.
