Válvula de enfriamiento para motor cohete con ergoles criotécnicos y motor cohete que comprende tal válvula de enfriamiento

Válvula de refrigeración para motor cohete (10), que comprende una carcasa (12) provista de un paso (14) que se extiende en dirección axial (X) y una válvula (16) alojada en la carcasa (12) y móvil con respecto a la carcasa (12) en el sentido axial (X), comprendiendo la válvula (16) un vástago (16B) que se extiende en el sentido axial (X) y un cabezal de cierre/apertura del paso (16B) solidario del vástago (16B), estando acoplada la varilla (16B) a la carcasa (12) por al menos un elemento bimetálico (18, 18') configurado para deformarse en la dirección axial (X) en función de la temperatura ambiente en el interior del paso (14) (Traducción automática con Google Translate, sin valor legal) To provide a cooling valve for a rocket engine with an improved cryogenic propellant, a rocket engine with a cryogenic propellant comprising the valve, and a spacecraft comprising the rocket engine.SOLUTION: A cooling valve 10 for a rocket engine includes a casing 12 having a passage 14 extending along an axial direction X, and a valve 16 that is housed in the casing 12 and is movable with respect to the casing 12 along the axial direction X. In the cooling valve 10 for a rocket engine, the valve 16 comprises a stem 16B extending along the axial direction X, and a head portion that is connected to the stem 16B to closely close or open the passage 14. The stem 16B is coupled to the casing 12 by at least one binary metal element 18, 18' which is configured to deform along the axial direction X as a function of the ambient temperature in the passage 14.SELECTED DRAWING: Figure 2
