PROBLEM TO BE SOLVED: To passively provide flows of cooling fluid to a hot cavity.SOLUTION: A thermal valve is disclosed. The thermal valve may provide one or more flows of cooling fluid to a hot cavity within a cooling circuit of a gas turbine engine. The thermal valve may include a temperature sensitive element and a valve assembly in communication with the temperature sensitive element. The valve assembly may include at least one inlet in fluid communication with at least one cooling fluid source, at least one outlet in fluid communication with the hot cavity, and at least one valve in communication with the temperature sensitive element. The at least one valve may be disposed between the at least one inlet and the at least one outlet. The temperature sensitive element may be configured to move the at least one valve between a closed position and an open position.SELECTED DRAWING: Figure 1 【課題】冷却流体の流れを高温キャビティに受動的に提供する。【解決手段】熱バルブが開示される。熱バルブは、ガスタービンエンジンの冷却回路内で冷却流体の１又はそれ以上の流れを高温キャビティに提供することができる。熱バルブは、温度感知要素と、該温度感知要素と連通したバルブ組立体と、を含むことができる。バルブ組立体は、少なくとも１つの冷却流体供給源と流体連通した少なくとも１つの入口と、高温キャビティと流体連通した少なくとも１つの出口と、温度感知要素と流体連通した少なくとも１つのバルブと、を含むことができる。少なくとも１つのバルブは、少なくとも１つの入口と少なくとも１つの出口との間に配置することができる。温度感知要素は、閉鎖位置と開放位置との間で少なくとも１つのバルブを移動させるように構成することができる。【選択図】 図１
