Abstract
Dispositivo perfeccionado de gato hidráulico de carrera regulada del tipo de camisa con orificios múltiples de paso del fluido, sucesivamente cubiertos o descubiertos por el pistón en las carreras de aceleración o de desaceleración, caracterizado porque reguladores de caudal de un tipo en sí conocido que incluyen una corredera deslizante equilibrada por un resorte de calibrado, están dispuestos en las alimentaciones del gato, regulando dicha corredera el caudal de evacuación del gato en posición de equilibrio entre, por una parte, sobre una de sus caras de extremo, la presión en el cilindro, aguas arriba de los orificios de evacuación múltiples, y por otra parte, sobre la otra cara, la presión aguas abajo de dichos orificios, aumentada en la presión del resorte de calibrado, controlando, sobre esta cara, la apertura del caudal de evacuación del gato, encontrándose la corredera del regulador dispuesta en el otro extremo del gato, debido a la inversión del sentido de las pérdidas de carga enlos orificios múltiples, impulsada al fondo del alojamiento e inactiva.
