Abstract

El objeto de la presente invención consiste en proporcionar una válvula de presión del tipo que tiene un carrete que puede desplazarse en el interior de un cuerpo de válvula y en la cual se aplica la misma fuerza de amortiguamiento en ambas direcciones de amortiguamiento del carrete de válvula. Otro objeto consiste en proporcionar un dispositivo de realimentación negativa que sirve para anular parcialmente las crestas transitorias que conducen a la inestabilidad de la válvula en una válvula de control de presión del tipo que tiene un carrete que puede desplazarse en el interior de un cuerpo de válvula.
