A fuel tank in a vehicle. The fuel tank includes a protective outer shell, an inner shell and a crush sleeve. The protective outer shell defines an outer tank. The inner shell defines an inner tank which holds fuel. The inner shell is housed in the outer shell and is isolated from the outer shell by a space. The crush sleeve is provided in the space between the outer shell and the inner shell. The crush sleeve supports the inner shell and maintains the inner shell in position relative to the outer shell. Wherein during an impact to the vehicle, the force of the impact causes the outer shell and the crush sleeve to deform and the inner shell to move relative to the outer shell.

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).

A tank manufacturing method includes the steps of (a) forming a reinforcing layer before hardening, (b) embedding at least a part of a label into the reinforcing layer before hardening, and (c) winding glass fiber with thermosetting resin before hardening impregnated so as to cover the label to form a surface layer before hardening. The step (a) includes (a1) forming an inner layer before hardening, and (a2) forming an outer layer before hardening having a cover rate lower than the inner layer before hardening and lower than 100%, the outer layer before hardening being arranged on the inner layer before hardening.

A method for manufacturing a fuel tank is described herein. The method includes subsequent to molding of a housing of a fuel tank, positioning a strut inside the housing. The method additionally includes snap-fitting a flexible projection of the strut with a corresponding flange section in a first wall of the housing, the flange section surrounding an opening in the first wall of the housing and the flexible projection including a surface overlapping an interior surface of the flange section subsequent to the snap-fitting.

The inner shell defines an inner tank which holds fuel. The inner shell is housed in the outer shell and is isolated from the outer shell by a space. The crush sleeve is provided in the space between the outer shell and the inner shell. The crush sleeve supports the inner shell and maintains the inner shell in position relative to the outer shell. Wherein during an impact to the vehicle, the force of the impact causes the outer shell and the crush sleeve to deform and the inner shell to move relative to the outer shell.

A sealing interface configured to prevent galvanic corrosion of a container having parts made of dissimilar materials includes a first part, a second part, and a sealant. The first part has a first sealing surface and a first exterior surface substantially perpendicular to the first sealing surface. The second part has a second sealing surface and a second exterior surface substantially perpendicular to the second sealing surface. One of the parts includes an external sealing chamfer on the respective sealing surface extending to the respective exterior surface. The sealant at least fills a space formed between the external sealing chamfer and the sealing surface of the other of the parts when the parts are connected, forming a barrier between the parts such that the exterior surfaces of the parts are not in contact and are separated by the sealant. The exterior surfaces may be flush when the parts are connected.

A tank made of resin capable of enhancing freedom of a tank shape and improving an ease of installation in a vehicle body. The tank made of resin is provided with a tubular projection projecting to an inside and an outside of a wall surface of a tank body that has a barrier layer, and an end edge part of the barrier layer is molded integrally with an outer peripheral resin part of the tubular projection.

The straddle vehicle includes a front wheel, a rear wheel, at least one tank, an internal combustion engine, a seat, and a steering handle. The front wheel is a steering wheel. The rear wheel is a drive wheel arranged located rearward of the front wheel. The tank is configured to be filled with a gaseous fuel. The internal combustion engine generates power using gaseous fuel filled in the tank. The driver sits on the seat. The driver performs the steering operation to the steering handle. The center of gravity of the tank is located closer to the steering wheel with respect to the center of gravity of the internal combustion engine.

A pressure vessel may include a body formed of a polymeric material. The body may extend between a first end and a second end. The body may include a center column defining a first inner volume extending between the first end and the second end. A wall may be connected to the center column. The wall may surround the center column and define a second inner volume therebetween. The second inner volume may be disposed annularly around, and fluidly separate from, the first inner volume. The pressure vessel may also include a first end cap coupled to the center column at the first end and second end cap coupled to the center column at the second end. The first end cap may close off the first inner volume at the first end. The second end cap may close off the first inner volume at the second end.

The invention relates to a combination tank having a double-walled inner container for temperature-insulated accommodation of a cryogenic fluid, which inner container has an approximately circular cylindrical cross-section and is closed off with end-side caps, wherein an outer container for accommodating at least one operating material is configured around the inner container, which outer container has a jacket having an approximately rectangular cross-section and end walls supported on the inner container, which end walls either sit in the gussets that remain between inner container and jacket, or are touched or penetrated by the caps of the inner container.
