Abstract

Muelle de gas con compensación de temperatura que tiene una sola derivación a través del pistón que es controlada por un miembro de válvula de material elastomérico, que restringe el flujo a través de la derivación cuando se comprime el muelle de gas (moviéndose el vástago de pistón dentro del cilindro) y produce una diferencia de presión a través del pistón que varía inversamente con la temperatura. La fuerza creciente que se opone a la compresión del muelle de gas debido a la diferencia de presión a través de la derivación cuando disminuye la temperatura del muelle de gas, y por tanto la fuerza de salida, mantiene la carga de mango más uniforme sobre un margen de temperaturas. El miembro de válvula elastomérico tiene muy poco efecto sobre el funcionamiento normal del muelle de gas en el modo de extensión (movimiento del vástago hacia afuera).
