Abstract
Un tensor hidráulico que tiene un miembro de soporte accionado hidráulicamente. Un par de válvulas de retención (214,230) permiten que el fluido fluya desde una fuente externa (224) de fluido a presión en una cámara de fluido (208). Las dos válvulas de retención forman una cámara estanca sustancialmente con el fin de proveer una presión suficiente para prevenir que el pistón (200) retroceda cuando se desactiva la fuente de fluido a presión.
