Fail-safe thermostat for vehicular cooling systems

摘要: A fail-safe thermostat for vehicular cooling systems is positioned in a junction leading to an internal coolant passageway, radiator passageway and bypass passageway. An open housing seated the supports fixed central rod extending into wax filled interior of movable cylindrical member which controls position segment main valve. Expansion forces first direction against compression spring. Fusible alloy disposed coupling between valve, melts at specific temperature range excess normal range. When this occurs released such way that spring valve second limit opposite expansion. closure one end may be used close concurrently with increased temperature.
