Embodiments of the invention provide a pressure vessel closure apparatus for a pressure vessel having a shell wall, a removable end cap, and an internal retaining groove along an interior surface of the shell wall. The retaining member can include a main-portion outer profile and an end-portion outer profile. The end-portion outer profile can deviate from the main-portion outer profile in order to provide a clearance between the interior surface of the shell wall and the retaining member for the insertion of the retaining member into the retaining groove. A stop can be secured in place with respect to the end cap or the shell wall in order to retain the retaining member within the retaining groove. The retaining member, as retained within the retaining groove by the stop, can retain the end cap within the pressure vessel when the pressure vessel is pressurized.

A fire extinguisher device for aircraft has a hanger structure and a reservoir of extinguishing agent, the aforementioned reservoir being hung beneath the aforementioned hanger structure by metal fittings held by fasteners to the aforementioned hanger structure. The aforementioned extinguisher wherein the reservoir has means of suspension and the hanger structure has carriers complementary to the means of suspension, the aforementioned means of suspension and the aforementioned carriers being such that when the fasteners are withdrawn, the reservoir is in a position called the “intermediate position,” in which the metal fittings are free and the reservoir is suspended by interaction of the means of suspension and the carriers. The disclosed embodiments also relate to a method for fastening such an extinguishing device.

A TPRD for a high pressure storage vessel including an integrated pressure sensor cooperative with an activation mechanism and a method of monitoring a TPRD for use in a fuel cell system. The TPRD comprises a release piston, moveable between an open and a closed position, which controls the flow of gas from a fuel storage vessel through a gas outlet port. The thermally activated activation mechanism comprises a gas-inlet chamber and a liquid-filled bulb having an air bubble. Upon activation, the release piston moves from the closed position to the open position. The integrated pressure sensor detects the pressure within the TPRD. A difference in pressure between that of the fluid within the fuel storage vessel and the pressure within the TPRD provides indicia of impaired movement of the release piston.

The metallic sealed double container of the present invention includes an outer container, an inner container, an outer lid for the outer container, and an inner lid for the inner container, all of which being formed from thin metallic sheet. Connection holes are formed in the outer lid and the inner lid by burring, and both end parts of thin-walled pipes are respectively connected while inserted in the connection holes. The inner lid is joined to the inner container, and the outer lid is joined to the outer container, thereby constituting a metallic sealed double container in which the inner container is isolated in the outer container. As a result, the weight of the metallic sealed double container is reduced, the temperature in the inner container can be maintained over long periods of time, and the heat-insulating effect of the resulting sealed double container is high.

There is a key for use with pressurized gas cylinders. The key includes a sleeve configured to fit over a lever arm of a gas cylinder. The key includes a handle extending from the sleeve, and having a body. The handle includes a first slot and a second slot extending through the body of the handle and configured to fit over a valve toggle of a gas cylinder. The handle includes a washer storage device extending substantially orthogonally from the body of the handle. The handle includes a flange coupled to an end of the washer storage device, opposite the body. The handle also includes a recess portion disposed about a base of the washer storage device of the handle and sized and shaped to receive a plurality of gas cylinder washers.

A tank mounting technique of the invention effectively responds to a variation in size of a high-pressure tank T in its longitudinal direction and allows positioning of the high-pressure tank T around its longitudinal axis. A tank receiving recess 110 provided below a vehicle platform F has a pair of a front inclined surface 112F and a rear inclined surface 112R arranged to face each other across a concave groove 114. A side face of the high pressure tank T is brought into contact with both the inclined surfaces 112F and 112R. An end face of a tank positioning groove TVS formed on the high pressure tank T is brought into contact with a contact structure 121 of a tank edge bracket 120. This arrangement enables the high-pressure tank T to be positioned in a vehicle vertical direction and a vehicle front-back direction, as well as in the tank longitudinal direction (in a vehicle width direction). The tank positioning groove TVS is aligned with a notch 122 formed in the tank edge bracket 120 to specify a rotational position of the high-pressure tank T around its longitudinal axis.
摘要:
A fuel tank of a spacecraft stores a liquid fuel and a pressurized propellant gas that drives the fuel out of the tank though a fuel extraction arrangement including a reservoir or fuel collection container and a tank outlet. A spiraling or J-shaped or hook-shaped fuel collection channel and plural obliquely sloping fuel flow channels connect the fuel collection container to an outlet pipe of the tank outlet. The channels are configured, dimensioned, oriented and arranged to ensure that fuel will be retained in the outlet pipe without leaking back into the fuel tank, even when the tank is oriented horizontally and has a low tank filling level. These structures produce a capillary pumping effect and use the surface tension to separate the fuel from the propellant gas, and allow the inner space of the collection container to be completely filled with liquid fuel.
