Abstract
Se describen aparatos de leva para uso con válvulas. Un aparato de ejemplo incluye una leva (300) que tiene una superficie de leva para acoplar un vástago de válvula (406), una primera porción de la superficie de leva para acoplar el vástago de válvula en una posición cerrada, una segunda porción (306) de la superficie de leva para acoplar el vástago de válvula en una posición abierta, y una tercera porción de la superficie de leva adyacente a la primera porción y que define un perfil curvado. La tercera porción es acoplar el vástago de válvula cuando la leva es girada a una primera posición intermedia entre la posición cerrada y la posición abierta. El aparato de ejemplo también incluye una cuarta porción (310) de la superficie de leva entre la segunda porción y la tercera porción y que define un perfil lineal. La cuarta porción es para acoplar la superficie del vástago de válvula conforme la leva gira entre la primera posición intermedia y la posición abierta.
