Device for injecting a fuel-gas mixture

Pressure regulator module for controlling a gas

Valve for control of a fluid

Valve e.g. solenoid valve, for use in e.g. internal-combustion engine, has valve unit with flat seat, for releasing and closing opening, where flow direction of gaseous medium through opening is same as actuation direction for opening valve

Pressure regulator for gas flow has chamber with built in proportional valve used to change flow orifice

Fuel cell system for use in motor vehicle, has compressor driven by high pressure of primary fuel and/or hydrogen, where primary hydrogen flows via pressure-reduction valve into compressor

Valve for controlling a gas flow, comprises lubricant chamber which borders on a guide gap between valve housing and magnetic armature

Gas valve for controlling flow rate of e.g. natural gas, in e.g. hybrid vehicle, has sealing seat with surface having channel-shaped contour with multiple risings and multiple recesses, which are arranged in circular and concentric manner

Fuel cell device with fuel metering device

Fuel cell installation comprising a dosing unit
