A vehicle is provided. The vehicle can include a cab, a plurality of wheels, one or more frame rails, an engine or power generation system, and a pressure vessel. The frame rails are configured to support the cab and the plurality of wheels. The engine or power generation system are configured to be powered by a fuel. The pressure vessel is configured to store the fuel to be used by the engine or power generation system. The pressure vessel can include a structural shell formed by filament winding upon a substantially cylindrical form.

Vehicles having composite interwoven gas containment assemblies

A pressure relief valve configured to vent a pressurized tank in the event of a fire is provided. The pressure relief valve includes a body, a vent passage, a plug and a latch. The vent passage is disposed through the body. The vent passage can be placed in fluid communication with an internal volume of a tank and with the atmosphere. The plug is moveably mounted in the vent passage. The latch has a blocking member disposed in contact with a control end of the plug in a first configuration and out of contact with the control end in a second configuration. The second configuration allows movement of the plug in the vent passage. One or both of a shape memory alloy wire and a trigger piston is configured to actuate the latch from the first to the second configuration. The shape memory alloy wire is configured to shorten when exposed to a temperature above a threshold temperature. The trigger piston moves, e.g., by a pressurized gas, in a trigger actuation passage to actuate the latch from the first configuration to the second configuration.

Pressure relief device

A fuel system is provided that includes a mounting block assembly configured to support an end of a fuel tank. The end of the fuel tank has a boss. The mounting block assembly encloses a space configured to receive the boss of the fuel tank. The fuel system also includes a bearing disposed in the space. The bearing has a support surface configured for sliding support of the boss of the fuel tank at an interface between the first portion and the second portion of the mounting block assembly. The fuel system also includes a sleeve. The sleeve is removably coupled to the boss of the fuel tank such that the sleeve is restrained longitudinally relative to the boss. The sleeve is configured to slide longitudinally relative to the support surface when the boss and sleeve are disposed on the support surface within the space of the mounting block assembly.

Fuel system with sacrificial neck sleeve

Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

Polymeric liner based gas cylinder with reduced permeability

A system for powering a vehicle is provided. The system can include an engine or power generation system to be powered by a fuel and a housing. The housing can be configured to couple to one or more frame rails of the vehicle, receive and protect a cylinder configured to store the fuel to be used by the engine or power generation system. The housing can have one or more access panels allowing access to an interior of the housing. The cylinder can include a first end portion, a second end portion, a central body forming an enclosed cavity for storing pressurized gas, a reinforcement structure disposed over the central body, and a metal foil interposed between the reinforcement structure and central body. The metal foil can be configured to reduce permeation of contents of the cylinder.

Gas cylinder with reduced permeability

A pressure vessel is provided that has a structural shell formed by winding filaments upon a substantially cylindrical form. The structural shell has a first filament and a second filament. The first filament includes of a first material. The first filament is wound about the form in a primarily hoop direction. The second filament includes a second material. The second material is different from the first material. The second filament is wound about the form in a primarily helical direction. The first filament and second filament are interwoven in a layer upon the form.

Fuel system mountable to a vehicle frame

A fuel system is provided that includes a fuel tank, a heat detector, and a control circuit. The digital heat detector is disposed in proximity to the fuel tank. The control circuit is coupled with the digital heat detector and is configured to detect that a thermal event has occurred. The fuel system is configured to implement an emergency countermeasure in response to the detection of the thermal event.

Systems for monitoring volatile fuel system components

A system includes a first valve fluidly connected to a first vessel and a second valve fluidly connected to a second vessel. The first valve includes a body and a piston. The body includes first and second ports and a bore having a longitudinal axis. The first port is in communication with the bore and an interior of the first vessel. The second port is in communication with the bore, the second valve, and an atmosphere exterior to the first vessel. The piston is movable along the longitudinal axis of the bore. A first position of the piston blocks the first port; a second position of the piston allows fluid communication between the first and second ports. The first valve is configured so that fluid pressure from the second valve, communicating through the second port, urges the piston to the second position.

System for multiple pressure relief device activation

A pressure vessel includes a shell, a liner, and a boss. The liner is positioned within the shell and defines the interior environment. The boss is located at a first interface between the shell and the liner. The boss includes a cavity and a venting structure located in the cavity. The cavity is located at a second interface between the liner and the boss, and the cavity is located at an interior surface of the boss in communication with the interior environment. A gas vent path is defined from the first interface, through the venting structure, and into the interior environment of the pressure vessel. The disclosure also describes a boss for a pressure vessel and a method of manufacturing the boss. The boss includes a port, a flange, a cavity and a gas venting structure. The cavity and gas venting structure are located on an interior of the flange.
