Abstract
A thermostatic bypass valve functions to regulate fluid temperature and also to act as a pressure relief valve using a single valve bore. The poppet valve includes a cylinder with a chamber that is thermally immersed in a source passageway such that the valve state is determined by the temperature of the fluid flowing through the source passageway as opposed to the fluid flowing through a return passageway. When the fluid in the source passageway is hot, a poppet is forced against the return passageway side of a valve seat. The poppet may either be rigidly attached to the cylinder or may slide with respect to the cylinder and be forced against the valve seat by a spring. A piston may either be rigidly attached to the housing or may be forced toward the valve seat by a spring.
