FORWARD POPPET THERMOSTAT

摘要

A thermostatic valve to be mounted in the coolant system of an internal combustion engine to control the flow of fluid through the system. A thermostatic valve of the forward poppet-type in which a single poppet cooperating with a single valve seating surface is independently responsive to both temperature and pressure for controlling the flow of fluid through said valve. The poppet is slidably engaged with the extending thermal element and spring biased into a seated or closed position. The poppet will unseat, or open, in response to an extension of the thermal element or, totally independently of the thermal element, will unseat in response to an upstream pressure sufficient to overcome the spring bias.
