り閉成し下降により開放する弁体と、この弁体に
閉成方向への偏倚力を与える第１スプリングと、
前記弁体に水圧が加わらないときその弁体を前記
第１スプリングの偏倚力に抗して所定量だけ開放
せしめる第２スプリングと、水温が一定以上にな
ると熱膨張し前記第１スプリングの偏倚力および
水圧に抗して前記弁体を全開せしめる熱膨張手段
とを具備したことを特徴とするサーモスタツト。 a valve body provided in an upward cooling water circulation path that closes as it rises and opens as it falls; a first spring that applies a biasing force to the valve body in the closing direction;
a second spring that opens the valve body by a predetermined amount against the biasing force of the first spring when no water pressure is applied to the valve body; and a second spring that thermally expands when the water temperature exceeds a certain level, thereby increasing the biasing force of the first spring. and thermal expansion means for fully opening the valve body against water pressure.
