SOUPAPE DE DÉRIVATION THERMIQUE EN CIRE UTILISANT UN AMORÇAGE AVEC DES SÉPARATEURS DE CIRE

摘要

A bypass system has a source of a fluid to be cooled and a heat exchanger for selectively cooling fluid. A piston (40) is moveable along an axis allowing movement of a valve poppet (22) toward and away from the valve seat (24). The piston contacts a boot (38). A wax element (36) is disposed in a chamber (49), such that the wax element expands as a temperature of the fluid to be cooled increases, and causes the valve poppet to move against the valve seat. The boot has wax separator structures (140). A bypass valve is also disclosed.
