    Abstract: A vibration isolator for connecting a first body and a second body. The vibration isolator includes a housing having a first chamber, a second chamber, and a port connecting the first chamber to the second chamber and permitting fluid to flow between the first chamber and the second chamber. The first and second chambers and the port defining a fluid reservoir. The isolator including a gas-to-fluid accumulator in fluid communication with the fluid reservoir through a first one-way valve and a second one-way valve. The first one-way valve allows fluid to pass only from the fluid reservoir to the accumulator and the second one-way valve allows fluid to pass only from the accumulator to the fluid reservoir. At least one of the first and second one-way valves being preloaded to a predetermined force to permit fluid flow through the at least one-way valve only when fluid pressure exceeds the predetermined force.

    Abstract: Un aislante de vibracion (10) para conectar un primer cuerpo y un segundo cuerpo, incluye un bastidor que tiene una primera camara (22), una segunda camara (26) y un puerto (24) que conecta la primera camara (22) con la segunda camara (26) y que permite que el fluido (34) fluya entre la primera segunda camara (22) y la segunda camara (26). La primera y la segunda camaras (22), (26) y el puerto (24) definen un deposito de fluido (27). El aislante (10) incluye un acumulador de gas a fluido (30) en comunicacion fluida con el deposito de fluido (27) a traves de una primera valvula unidireccional (140) y una segunda valvula unidireccional (142). La primera valvula unidireccional (140) permite que el fluido (34) pase solamente desde el deposito de fluido (27) hacia el acumulador (30) y la una segunda valvula unidireccional (142) permite que el fluido (34) pase solamente desde el acumulador (30) hacia el deposito de fluido (27). Al menos una de la primera y la segunda valvulas unidireccionales (140), (142) esta precargada a una fuerza predeterminada para permitir que el fluido fluya a traves de la al menos una valvula unidireccional (140), (142) solamente cuando la presion del fluido excede la fuerza predeterminada.

    Abstract: A pressure indicator (106) according to the present invention monitors the pressure of the fluid in a vessel (102). One embodiment of the present invention comprises a closed pressurized gas volume (210) behind a dimpled metal diaphragm (208). In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm (208) to hold the diaphragm (208) in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of th e diaphragm (208) will overcome the force of the fluid pressure acting on the external surface of the diaphragm (208), thereby moving the diaphragm (208) into a convex geometry. A viewing window (110) disposed in the side of the vessel (102) can be used to view the pressure indicator (106) and determine the shape of the indicator diaphragm (208).
