  • Suspension system for a vehicle with a tank for liquified gas
    Patent number: 7198301
    Abstract: A suspension system for carrying a compressed gas fuels in vehicle. The suspensions arms and springs are configured to maximize the space between the wheels while providing a high degree of suspension stiffness to maintain proper wheel alignment during cornering, braking and in rough terrain. The suspension arms have two broadly-spaced attachment points to the chassis that provides structural rigidity to the rear suspension subassembly.
    Type: Grant

  • Compressed gas manifold
    Patent number: 6321775
    Abstract: A compressed gas storage cell interconnecting manifold including a thermally activated pressure relief device, a manual safety shut-off valve, and a port for connecting the compressed gas storage cells to a motor vehicle power source and to a refueling adapter. The manifold is mechanically and pneumatically connected to a compressed gas storage cell by a bolt including a gas passage therein.

  • Compressed gas fuel storage system
    Patent number: 6257360
    Abstract: A compressed gas vehicle fuel storage system comprised of a plurality of compressed gas pressure cells supported by shock-absorbing foam positioned within a shape-conforming container. The container is dimensioned relative to the compressed gas pressure cells whereby a radial air gap surrounds each compressed gas pressure cell. The radial air gap allows pressure-induced expansion of the pressure cells without resulting in the application of pressure to adjacent pressure cells or physical pressure to the container. The pressure cells are interconnected by a gas control assembly including a thermally activated pressure relief device, a manual safety shut-off valve, and means for connecting the fuel storage system to a vehicle power source and a refueling adapter. The gas control assembly is enclosed by a protective cover attached to the container. The system is attached to the vehicle with straps to enable the chassis to deform as intended in a high-speed collision.
