The pressure pack includes a gas storage vesse
A litter for carrying a patient in a supine position, such as a stretcher or trauma board, includes a support panel and a pressure pack for providing a portable supply of medicinal gas, such as oxygen, that can be administered to a patient on the liter. The pressure pack includes a gas storage vessel formed from a plurality of polymeric hollow chamber having either en ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The storage vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The storage vessel further includes a fluid transfer control system attached to the storage vessel for controlling fluid flow into and out of the pressure vessel and a gas delivery mechanism for delivering gas from the storage vessel to a user in a breathable manner.

A vehicle comprising: an accumulator for storing fuel delivered from a fuel feed pump; at least one fuel injection valve mounted in an internal combustion engine cylinder; a pressure valve with a first end fluidly communicating with the accumulator and a second end fluidly communicating with a relief line to provide a fluid passage from the accumulator to a fuel tank, the pressure valve further including: a valve body having in a first end a valve hole, the valve body having a sliding bore with a greater cross section than the valve hole, the valve body having a third bore, the valve body having a through passage, the third bore having a greater cross section than the sliding bore, the valve hole connecting the accumulator to the sliding bore, the through passage connecting the third bore to the relief line; a piston having a first cross section portion slidably supported in the sliding bore, the piston having a large second cross sectional portion which has a larger outside diameter than the smaller first cross section portion, a valve element that moves with the piston as one body and is proximate the valve hole; a spring biasing said piston to a first position; wherein said piston and valve body are movable between the first position and a second position, wherein the valve element blocks fluid flow through the valve hole and at least a portion of said large cross sectional portion is surrounded by said large cross sectional bore in said first position; and wherein the valve element opens fluid flow through the valve hole and from the first end to the second end in the second position; and a damper chamber located downstream of the sliding bore in the valve body and housing the large diameter portion of the piston together with fuel, wherein the damper chamber is a recessed portion of the valve body having a larger inside diameter than the sliding bore, having an opening in the end face on the spring side of the valve body, and being defined by an end face of the large diameter portion of the piston on the sliding bore side, an inner wall surface of the recessed portion, and a stepped portion between the recessed portion and the sliding bore; wherein the large diameter portion of the piston and the recessed portion of the valve body are disposed so that the large diameter portion of the piston exits the recessed portion of the valve body when the piston moves beyond a predetermined value. 6. A pressure valve, for supplying fuel from an accumulator to a relief line, said valve comprising: a valve body having in the first end a valve hole, the valve body having a sliding bore with a greater cross section than the valve hole, the valve body having a third bore, the valve body having a through passage, the third bore having a greater cross section than the sliding bore, the valve hole connecting the accumulator to the sliding bore, the through passage connecting the third bore to the relief line; and a piston having a first cross section portion slidably supported in the sliding bore, the piston having a larger second cross sectional portion which has a larger outside diameter, a valve element that moves with the piston as one body and is proximate the valve hole; and a spring biasing said piston to a first position; and wherein said piston and valve body are movable between the first position and a second position, wherein the valve element blocks fluid flow through the valve hole and at least a portion of said large cross sectional portion is surrounded by said large cross sectional bore in said first position; wherein the valve element opens fluid flow through the valve hole and from the first end to the second end in the second position; a damper chamber located downstream of the sliding bore in the valve body and housing the large diameter portion of the
