- Hydrogen Heating Tank Using Incompressible Fluid and Waste Heat
Waste heat circulated through an incompressible fluid heats and vaporizes hydrogen in a tank, avoiding combustion losses and heavy heat exchangers.
- Exhaust Heat Exchange Using Hydrogen Tank Cooling to Suppress Fog
Cold hydrogen tank heat exchange condenses exhaust water vapor, cutting fog formation and improving visibility around hydrogen-powered vehicles.
- Hydrogen Exhaust Cooling Using Tank Heat Exchange to Condense Fog
Exhaust heat exchange with the hydrogen tank condenses water vapor, cutting fog formation and improving visibility around heavy-duty vehicles.
- Hollow Valve Dimensions for Hydrogen Engine Heat Dissipation
Optimized hollow valve cavity and wall dimensions improve heat dissipation and wear resistance in hydrogen combustion engines.
- Variable-Volume Fuel Chambers for Stable Gaseous Fuel Pressure
Alternating variable-volume chambers match tank and supply pressures to deliver steady gaseous fuel flow without separate regulators or compressors.
- Gaseous Fuel Storage Heating Using Exhaust Gas Feedback Control
Exhaust gas is routed through a controlled valve to heat vehicle fuel storage only when tank temperature is low, improving efficiency and avoiding overheating.
- Exhaust-Heated Gaseous Fuel Storage With Overheat Feedback Control
Waste exhaust gas heats the fuel storage housing, while valve feedback control prevents overheating and reduces energy loss.
- Self-Aligning Valve Disk Assembly for Pressure Regulator Sealing
A pivoting, rotating valve disk compensates for regulator misalignment to improve sealing, limit pressure build-up, and reduce stem damage.
- Variable-Orifice Pressure Relief Valve for Hydrogen Blowdown Control
A spring-biased piston varies the relief orifice to control hydrogen flame size while shortening tank blowdown time.
- Variable-Orifice Pressure Relief Valve for Hydrogen Blowdown
A spring-biased piston varies the relief orifice with pressure to speed hydrogen tank blowdown while controlling flame size.
- High-Pressure H2 Manifold Sealing for Repeatable Pipe Connections
Segmented screw plugs and sealing plates prevent radial thread deformation in high-pressure H2 manifolds for safer, repeatable connections.
- Pressure Regulator Valve Bearings for Smooth Sliding Under Tilt
Rigid annular resin bearings prevent piston-to-wall contact during valve tilt, reducing friction and preserving pressure regulation.
- Pressure Regulator Piston-Rod Structure for Stable Secondary Pressure
A movable rod fitted in the piston offsets axial deviation and pressure loads, reducing sliding resistance while stabilizing secondary pressure.
- Elastic Valve Seat Structure for Regulator Leak Prevention
An annular grooved elastic valve seat maintains sealing despite valve misalignment, reducing leakage and precision assembly demands.
- Hydrogen Hose Fitting Crimp Sleeve for High-Pressure Sealing
A dedicated crimp projection compresses the hose over an O-ring to improve sealing and limit hydrogen permeation in high-pressure lines.
- Outward-Opening Gas Valve With Annular Throttle for Jet Shaping
An annular gap downstream of the sealing seat separates mass flow throttling from jet shaping for more precise gas dosing and guidance.
