An excavator has a unitary fluids tank formed from moldable cross linked high density polyethylene. The fluids tank has a compartment for hydraulic fluid and a compartment for power unit fuel. The compartments are separated by a coextensive integral wall providing an insulating barrier are formed from a polyethylene foam providing an insulating barrier between the compartments.

To make a reserve tank be hardly affected by the heat of an engine. An engine room (5) is totally covered by an exterior cover (9) including openings (44) at the upper surface, and includes in the inside thereof an engine (13), a radiator (24), a cooling fan (20) for sucking external air and cooling the radiator, and a reserve tank (30) for storing cooling water of the engine. The reserve tank (30) is disposed at a position above the engine (13) and facing the openings (44) and a position on the upstream side of the flow of the air with respect to the openings (44).

A protective structure for a fuel pump includes a protector including a connecting wall, a first protective wall, and a second protective wall. The first protective wall and the second protective wall are disposed outside the fuel pump assembled to an internal combustion engine. A standing surface of the second protective wall on a side opposite to a second base end surface in a standing direction of the second protective wall includes a curved surface that is concave on the second base end surface side and that becomes closer to the second base end surface side as the curved surface becomes farther from the first protective wall.

A reinforcement for a tank wall of a vehicle tank includes at least one reinforcing shield for flanking the tank wall, a shield support for supporting the reinforcing shield, and a clamping element. The shield support is axially secured in an axial direction on a clamping element. At least a portion of the reinforcing shield extends in a flank direction transverse to the axial direction.

A heat shield for a motor vehicle includes an elongated planar shield body for separating an exhaust pipe and a fuel tank of the motor vehicle, the shield body extending longitudinally along a longitudinal axis between the exhaust pipe and the fuel tank, the shield body having a generally concave surface extending from the axis to first and second vertical walls along first and second edges of the shield body, a forward attachment portion for attaching the shield body to a frame of the motor vehicle longitudinally forward of the fuel tank, a rearward attachment portion for attaching the shield body to the frame of the motor vehicle longitudinally rearward of the fuel tank, and a water escape port in the first vertical wall.

The invention provides a device for protecting a high-pressure gas tank of a motor vehicle. The device includes at least one heat-conducting plate and a thermal triggering unit. The heat-conducting plate has a distal region and a proximal region. The proximal region is arranged immediately adjacent to the thermal triggering unit and the distal region is arranged at a distance from the thermal triggering unit. The heat-conducting plate may be shaped so that it tapers from the distal region to the proximal region. The proximal region itself may be shaped in a tapering fashion. The heat-conducting plate may include heat-conducting fibers.

A vehicle is driven by energy generated from a drive unit supplied with gas fuel, and includes a fuel supply module that includes a fuel tank in which the gas fuel is stored, a regulator that is connected to the fuel tank and adjusts the gas fuel output from the fuel tank to predetermined pressure, a fuel output port through which the gas fuel adjusted by the regulator is output, and a support that supports devices including the fuel tank, the regulator, and the fuel output port, and includes an attachment portion detachably attached to the vehicle while supporting the devices.
