Abstract:
Center-filled toroidal tank for automotive, upper and lower steel plates (1) are welded to the main part to form a pressure vessel, of which there is no hollow in the center. There is a hole for valve fitting on the side of the upper plate (1), which is covered by a lid (4) from the top. On the side of the hole, there is an inlet and outlet connector (5) to connect to conversion system, which is bent at an angle of 90 degrees from the side of the valve. This toroidal tank can be installed either in spare tire hole or underneath the car.
Abstract:
This invention is directed to pressure vessels in which the strength necessary to withstand the pressure exerted by a contained fluid under intended operating pressures is provided by a dry filamentous over-wrap.
Abstract:
An end fitting for a cylindrical high pressure vessel made from components all having thin walls, thereby tripling the practical diameter of such pressure vessels. The end fitting includes a toroidal shell defining a hole; centrally disposed piece for closing the hole comprising a pipe and a center end fitting and structural members. In a first embodiment, the structural members comprise slices of an end of the pipe welded to the outer cylindrical wall of the vessel. In a second embodiment, the structural members are plates connecting the pipe to the outer cylindrical walls. In the third embodiment, the plates connect an extension of the outer cylindrical wall beyond the toroidal shell to an extension of the outer cylindrical wall of the pressure vessel. The center end fitting may be hemispheric or ellipsoidal.
Abstract:
A gas containment and supply apparatus is described consisting of a gas reservoir vessel (1) capable of pressurised gas containment fitted with a gas supply aperture (8) provided with supply means connectable to the gas supply aperture to provide for supply of the gas and control means to control the rate of supply of the gas, in which the gas reservoir is a toroidal pressure vessel comprising a metallic toroidal shell (2) having wound on its surface a tensile load bearing layer of high tensile strength non-metallic fibre (4), the fibre being aligned in a substantially meridional direction on the toroidal shell. Human portable breathing apparatus is described utilising the above.
Abstract:
A fluid storage vessel (60) such as for automotive fuel has opposed end walls (66, 68, 80) connected at or adjacent an outer periphery (82), and an annular internal wall (76) extending between the opposed end walls whereby it comprises a first inner chamber (70) defined by inner portions (66, 68) of the opposed end walls of the vessel and the internal wall (76) and a second annular chamber (64) around the first chamber defined by the internal wall and outer portions (80) of the opposed end walls connected at the outer periphery (82) of the vessel. The internal wall (76) prevents fluid flow between the chambers and each chamber (64, 70) is provided with a respective fluid flow connection (50, 52) to the exterior.
Abstract:
The object of the present invention is a series of improvements in GPL tanks for motor vehicles, both cylindrical and toroidal, which make it possible to house within the tank (1) ifself, by means of a pre-inserted mounting staff, the pump (5) needed to feed injection motors, which is inserted and set inside the tank through an appropriately-sized compartment (3) which can be sealed tight following the insertion of the pump by means of a flange equipped with the ring for the mounting of the multi-valve unit.
Abstract:
This invention relates to a pressure vessel having a one-piece polymeric composite with a weldable metal fitting such that the pressure vessel can be coupled to a source of compressed fluid by a welded connection.
Abstract:
The present invention is directed to a pressure vessel comprising a conductive composite boss wherein the composite boss is isolated from contact with materials with different electrical potentials so as to substantially eliminate the possibility of galvanic corrosion.
Abstract:
A toroid pressure vessel includes a toroid body having an inner shell and an outer shell. The toroid body includes a toroid outer perimeter. The outer shell extends along the toroid outer perimeter. A planar exterior face extends along at least a portion of the outer shell and the toroid outer perimeter. A support belt circumscribes the toroid outer perimeter and is coupled along the planar exterior face. The support belt braces and supports the pressure vessel along the toroid outer perimeter against bulging force (and hoop stress) generated by pressurized fluids within the vessel. The support belt facilitates the use of thinner pressure vessel shells and thereby decreases the weight of the pressure vessel while providing a support to the outer shell that substantially prevents deformation of the planar exterior face.
