Methods and systems are provided for a baffle system of a fuel tank. In one example, a baffle system for a fuel tank may include a horizontal section and a vertical section, where the vertical section is arranged perpendicular to the horizontal section and includes a first end coupled to the horizontal section. The vertical section may be rigidly attached to a top surface of the fuel tank via an attachment interface.

Various techniques are provided for an energy absorbing fluid bladder. In one example, the fluid bladder includes a bladder body and a perforated baffle structure. The perforated baffle structure can be disposed within the bladder body and configured to mitigate a pulse of fluid (e.g., fuel) moving within the bladder body before the pulse reaches the bladder body. Related methods are also disclosed.

A baffle clip shield for protecting a clip attaching a baffle to a fuel tank to protect the fuel tank from heat from an exhaust chamber located near the fuel tank is disclosed. The clip shield includes a spring foot extending from the rear side of the clip shield, the spring foot having a hook distal end that is pushed radially inward by the inclined wall as the clip shield is installed, the hook distal end of the spring foot being insertable into a hole in the inclined wall of the clip receiving portion, the hook distal end moving radially outward when installed in the hold, the hook distal end creating an interference fit with the inclined wall to prevent removal of the clip shield.

A tank for transporting a liquid is disclosed. In some implementations, the tank includes a carrier having a plurality of compartments, each compartment of the plurality of compartments having an opening for containing one or more baffles. In some implementations, the tank includes a plurality of posts that are securable relative to the tank and configured to support the one or more baffles. In some implementations, the posts are removed from the tank to facilitate installation of the baffles. In some implementations, the posts are rotatable to facilitate installation of the baffles. In some implementations, the tank is a two-piece tank which facilitates access to the one or more baffles.

A baffle clip shield for protecting a clip attaching a baffle to a fuel tank to protect the fuel tank from heat from an exhaust chamber located near the fuel tank is disclosed. The clip shield includes a spring foot extending from the rear side of the clip shield, the spring foot having a hook distal end that is pushed radially inward by the inclined wall as the clip shield is installed, the hook distal end of the spring foot being insertable into a hole in the inclined wall of the clip receiving portion, the hook distal end moving radially outward when installed in the hold, the hook distal end creating an interference fit with the inclined wall to prevent removal of the clip shield.

Fuel tank made of thermoplastic material comprising baffle components provided therein in the form of at least one baffle element (2) comprising at least one wall portion (4) which is clamped approximately centrally and/or at the end, so that said wall portion may perform relative movements in relation to the tank, caused by splashing movements of the fuel, at least one fastening foot being provided for the clamping, the base thereof being provided with at least one through-hole, through which the fastening foot is riveted and/or welded to the tank wall (2).

A fuel tank for a truck, the fuel tank having a fuel tank body with a peripheral wall and end walls that define at least one receptacle to receive a liquid or gaseous medium. At least one baffle is fixedly attached to the inside surface of the peripheral wall via an inner fixing member. An outer fixing member is to fixedly attach the fuel tank body to the chassis of the truck, and is also connected to the inner fixing member through the peripheral wall.

A rigid connecting device for connecting the upper and lower surfaces inside an oil tank includes a connecting rod. The upper and lower sides of the connecting rod are each provided with a connecting end surface. The connecting end surface is provided with material-passing hole. The outer surface of the rigid connecting device is covered with high-density polyethylene. The upper and lower surfaces of the oil tank are connected by a connecting rod, and such arrangement is locally applied to areas where the rigidity of the oil tank is poor, so there are more effective space. The part of the rigid connecting rod contacting with the oil fuel is made of high-density polyethylene, so the requirements of strength and anti-corrosion can be satisfied.

The invention relates to a fuel tank for a motor vehicle, comprising a tank body made from thermoplastic with a tank wall which defines a tank volume which can be closed in a substantially fluid-tight manner, with at least one filler opening and with one or more functional insert components which are arranged within the tank volume, at least one blind opening with a single use closure being provided in the tank wall.

A liquid tank includes a tank wall enclosing a tank volume and at least one relief structure facing the tank volume on an inner side of the tank wall. The relief structure is formed as one-piece with the tank wall. Two shell parts can be joined along a joining surface to make a section of the tank wall. One of the shell parts can include a tank bottom. At least one part of the relief structure can be formed on the tank bottom. The relief structure can include projections protruding into the tank volume along a local direction of projection.
