A baffle system includes a baffle (40) located in a tank (16) for containing liquid (e.g. an aircraft fuel tank). The baffle (40) is a tubular member through which a liquid may flow. The baffle (40) comprises: a first tubular portion (42) providing a tubular outer wall, and a second tubular portion (44) located within the first tubular portion (42) and providing a tubular inner wall. The first and second tubular portions (42, 44) are substantially parallel. The first and second tubular portions (42, 44) are spaced apart to define a chamber (46) therebetween. The baffle (42, 44) further comprises radial side walls between the first and second tubular portions (42, 44) such that the chamber (46) is a sealed chamber. The chamber (46) may be filled with a compressible gas or gaseous mixture.

A tank for transporting fluids on a truck chassis includes a front wall, side walls, a back wall, a top, and a floor. Interior stairs extend from the floor to an opening in the top to allow stair access into the interior with integrated safety handrails on the fill port cover. Stair toe kicks act as internal transverse baffles to help control fluid motion and surging. The stairs also act as a structural stiffener between longitudinal baffles. Horizontal baffles assist in controlling fluid motion and surging. Formed baffles provide strength and stiffness. A baffle interlocking system improves joint integrity and aids manufacturing. Formed outer skins provide structural strength for the tank. Ports located in front and rear bulkheads may be used for tank ventilation or, depending on local safety codes, as secondary access points.

A distensible fuel tank included in a vehicle, comprising a housing and a compliance structure coupled to the housing, the compliance structure including a support element coupled to a first side of a structural element and a reinforcing element coupled to a second opposing side of the structural element.

A fuel tank for a transport refrigeration system is provided. The fuel tank includes an elongate tank body. The elongated tank body has a first end wall; a second end wall; a sidewall extending between the first and second end walls; and an interior space defined by the sidewall and the first and second end walls. The fuel tank further includes a fuel tank vent configured to vent air outside of the fuel tank; a fuel outlet fitting; a fuel discharge tube fitting; and a fuel pickup tube fitting. The entire tank body can be made of a plastic.

A non-metallic transfer fuel tank, configured for placement in a spare tire location on a vehicle, includes a rigid non-metallic tank body with a plurality of cutouts formed in the tank body. A fill neck is coupled to the tank body along with a fuel line connector which connects the tank to the vehicle's existing fuel system. A mounting neck formed in the tank body contains a mounting rod. The mounting rod is coupled to a base plate which is below the tank body. The mounting rod is also coupled to a mounting plate which is located above the tank body. The mounting plate is further configured to couple in a winch location in the spare tire location on the vehicle using the same mounting method as was used to mount the spare tire winch.

A fail safe container and container insert are disclosed. A flexible container insert may convert energy from a catastrophic event, including but not limited to collisions, accidents, impacts, pressure container failures or explosions such as detonations, or other catastrophic incidents, into a stretching of an internal structure of a fail-safe container insert to minimize or prevent failure of the container insert and/or the container. The stretchability of the container insert may accommodate both temperature and shape changes to protect a container, including but not limited to a pressure vessel, from rupture or other failure. Accordingly, a container insert may be considered self-healing in that it may absorb the effects of catastrophic events to prevent failure, may return to a generally previous condition, and/or may seal or otherwise reduce or minimize breaches when they do occur.

A tank system of a motor vehicle includes a volume modifying element, having a compensation volume, which is provided in the inner chamber of the fuel tank and which is used to equalize the vapor pressure. The compensation volume is connected to the surrounding area. The only connection between the volume modifying element and the surrounding area is formed by a storage unit of the gaseous fuel components and the inner chamber of the fuel tank is connected to the surrounding area by a valve unit. The valve unit is normally open when filling the fuel tank and when exceeding or falling below the pressure limits in the inner chamber of the tank, and is otherwise closed. The storage unit is connected to the valve unit. The volume modifying element and the valve unit are designed in such a way that vehicles which are parked for several days do not undergo diurnal losses due to changes in temperature of the surroundings, due to the fact that the vapor pressure equilibrium in the fuel tank can be maintained by the automatic supply and removal of ambient air in the, or from the, volume modifying element as long as the valve unit remains closed.

BAFFLE Disclosed is a baffle (40) for locating in a tank (16) for containing liquid (e.g. an aircraft fuel tank). The baffle (40) is a tubular member through which a liquid may flow. The baffle (40) comprises: a first tubular portion (42) providing a tubular outer wall, and a second tubular portion (44) located within the first tubular portion (42) and providing a tubular inner wall. The first and second tubular portions (42, 44) are substantially parallel. The first and second tubular portions (42, 44) are spaced apart to define a chamber (46)therebetween. The baffle (42, 44) further comprises radial side walls between the first and second tubular portions (42, 44) such that the chamber (46) is a sealed chamber. The chamber (46) may be filled with a compressible gas or gaseous mixture.

A baffle for use in a fuel tank has a sidewall and an interior space. The sidewall is formed of a flexible material so as to be radially compressible. The compressibility of the sidewall allows the baffle to be inserted through a hole which is smaller in diameter than the uncompressed diameter of the baffle. The baffle is preferably also longitudinally compressible so that it can be mounted in fuel tanks of varying depths.

A toolbox supporting transfer fuel tank is provided. The transfer fuel tank includes a tank body comprising a vertical portion and a toolbox supporting portion, the tank body having an inner volume, a fill tube coupled to a top surface of the tank body and at least one baffle support extending from a side of the tank body into the inner volume of the tank body. The transfer fuel tank may also include a pickup tube support formed in a bottom surface of the tank body and a strengthening channel formed in the top surface of the tank body to provide rigidity to this area of the tank body to support the transfer pump. The transfer fuel tank may further include at least one lower baffle extending from a rear surface of the tank body and contacting the toolbox supporting portion of the tank body.
