Abstract:
The present invention discloses an operating fluid container (10) made of thermoplastic material for a motor vehicle and a method for equipping an operating fluid container with a stiffening element (20). The operating fluid container (10) here has the following features : the operating fluid container (10) has a container opening (12) which is arranged in a container upper shell (11) and is edged by a surround (13); the operating fluid container (10) comprises a tubular stiffening element (20) arranged in the operating fluid container (10); on the end, the stiffening element (20) has a circumferential connecting edge (21) in contact with the container upper shell (11); in a plan view onto the container upper shell (11), the container opening (12) is surrounded by the connecting edge (21); the stiffening element (20) is integrally connected to a container lower shell (14) and by means of the connecting edge (21) to the container upper shell (11); and the stiffening element (20) counteracts deformation caused by the internal pressure of the operating fluid container (10).
Abstract:
Barrier structure placeable as a projectile-disabling, anti-liquid-leakage protective shield for the outside surface of a container designed to hold liquid of a certain nature including (a) a first-type (innermost) layer formed as an expanse of high-elastomeric material which is substantially fully self-healing via elastomeric behavior with regard to a piercing projectile wound, (b) a second-type (intermediate) layer disposed adjacent one side of the first-type layer as an expanse including a body of substantially the same high-elastomeric material in which there is contained a distribution of liquid-imbiber beads which react, and expand three-dimensionally in relation, to contact with liquid of the mentioned certain nature, and (c) a third-type (outermost) layer disposed adjacent the second-type layer, and formed as an expanse of substantially the same high-elastomeric material employed in the first- and second- type layers. In one embodiment of the invention, these layers are dimensioned whereby the first- and third-type layers each possesses a thickness substantially twice that of the second-type layer, and in a second invention embodiment, no matter the thickness of the innermost layer, that of the outermost layer is substantially twice that of the intermediate layer.
Abstract:
A fluid receptacle may include an outer wall defining a periphery of the fluid receptacle, and an inner wall. The inner wall may be connected to the outer wall at certain locations and spaced from the outer wall at other locations providing gaps between the outer wall and the inner wall. In some implementations, the inner wall may be complete or continuous and liquid fuel may be contained within the inner wall. In other implementations, liquid fuel may be received between the inner and outer walls.
Abstract:
Barrier structure (10) for use as a projectile-disabling, anti-liquid-leakage protective shield for the outside surface of a container including a first layer (16) composed of an elastomeric material which is substantially fully self-healing via elastomeric behavior, a second layer (18) disposed adjacent one side of the first layer as an expanse including a body of substantially the same high- elastomeric material in which there is contained a distribution of liquid-imbiber beads ( 18b) which react, and expand three- dimensionally in relation, to contact with the liquid, and a third layer (20) disposed adjacent the second layer, and composed of substantially the same high-elastomeric material employed in the first and second layers. In one embodiment of the invention, the first and third layers each possesses a thickness substantially twice that of the second layer. In a second embodiment, the thickness of the third layer is substantially twice that of the second layer.
Abstract:
Methods and apparatus for containing a hazardous material according to various aspects of the present invention operate in conjunction with a container having two compartments. The first compartment is configured to contain the hazardous material, and the second compartment contains a hazard control material. The container may further comprise a wall separating the first compartment from the second compartment. The wall is configured to open upon occurrence of a trigger event.
Abstract:
Verfahren zum Betrieb eines Fahrzeug-Kraftstofftank-Systems, insbesondere eines Kryotank-Systems, bspw. für flüssigen Wasserstoff, wobei Elemente des Tank-Systems, wie Leitungen, Ventile oder ähnliches und/oder ein Speicherbehälter für den Kraftstoff zumindest teilweise von einer Kapsel umgeben sind, deren Innenraum in Abhängigkeit zumindest einer Randbedingung regelmäßig entlüftet wird. Die Entlüftung kann bspw. mittels eines inerten Gases als Spülmedium durchgeführt werden. Grundsätzlich wird zur Entlüftung des Kaspsel-Innenraums ein Druckgefälle erzeugt und es wird das hierbei abgeführte Gas, das über unvermeidbare Leckage aus dem Tank-System in den Innenraum gelangt ist, gezielt entsorgt, so dass keine Gefährdung für die Umgebung besteht. So kann das Gas verbrannt oder katalytisch oxidiert werden. Die sog. Entsorgungsvorrichtung kann ein separater Brenner sein oder durch die das Fahrzeug antreibende Brennkraftmaschine gebildet werden. Als Vorrichtung zur Erzeugung eines Druckgefälles kann ein außerhalb der Kapsel angeordnetes Gebläse zum Einsatz kommen, es kann sich hierbei aber auch um ein Bestandteil einer das Fahrzeug antreibenden Brennkraftmaschine handeln. Schließlich können zur Erzeugung des Druckgefälles konvektive Kräfte oder der sich bei bewegtem Fahrzeug aufbauende Staudruck genutzt werden.
Abstract:
A multilayered fuel tank (10) for a motor vehicle is disclosed having a fuel tank body (32) for holding liquid and vapour fuel comprising a bottom wall (46), side walls (45) and a top wall and a plurality of fuel tank components (35) located on the top wall and seams (37) located on the side walls. A tank cover (36) is connected to the fuel tank body to define a vapour collection chamber (34). The tank cover encapsulates the top wall and the fuel tank components and seams thereby trapping any fuel vapours that may escape from the tank body, the fuel tank components and the seams. Also disclosed is a method of making the multilayered fuel tank and a method of preventing fuel vapours from escaping from a fuel tank to the environment.
Abstract:
The invention relates to an operating fluid tank (1), in particular a fuel tank composed of plastic having a substantially closed tank body composed of thermoplastic material, preferably based on polyethylene, and having a jacket composed of a multi-layer composite material surrounding at least parts of the tank body.
