The invention relates to a fuel cell installation comprising a fuel cell unit (). Said installation is also provided with a dosing unit () which comprises at least one dosing valve () and is used to dose a fuel () for at least one anode () of the fuel cell unit (), and a starting valve for dosing the fuel () for at least one cathode () of the fuel cell unit () during a starting phase. The aim of the invention is to be able to produce and operate one such fuel cell installation in an economical manner. To this end, at least one throttle element () comprising a fixed internal cross-sectional area is used to fix the maximum quantity of fuel that can be dosed in the starting phase.

Fuel cell system with a metering unit

A pressure regulator module for controlling a gas is provided, which includes a chamber, at least one gas inlet, and at least one gas outlet. In addition, a proportional valve operating essentially according to the pressure-equalization principle is post-connected to the gas inlet and is pre-connected to the chamber, and the proportional valve acts together with a pressure sensor situated in the chamber.

Pressure regulator module for controlling a gas

A valve for controlling a fluid, in particular for controlling a gas. The valve includes a valve housing which accommodates an electromagnetic actuating unit for a solenoid armature which is guided axially displaceably in the valve housing and which cooperates with a valve seat via a valve-closing member, so that a fluid stream from an inflow side to an outflow side of the valve is controllable. At least one lubricant chamber adjacent to the guide gap between the valve housing and the solenoid armature is provided.

Valve for controlling a fluid

A device for injecting a fuel-gas mixture includes a cost-effective gas-containing sleeve which is capable of being easily assembled and simply adjusted. The gas-containing sleeve abuts with its casing part, for example, only on four rounded-off edges of the square valve end, while the casing part surrounds the surfaces of the valve end with a radial clearance, so that gas interspaces are formed in between for supplying gas. The injection device is particularly suited for injecting a fuel-gas mixture into the intake manifold of a mixture-compressing internal combustion engine having externally supplied ignition.

A magnet system for magnet valves for controlling liquids including an electromagnet and a permanent magnet that produces magnetic fluxes, the magnetic fluxes of which are oriented opposite one another in a working air gap formed between a free-floating armature and a magnet pole. To attain a course of the force of attraction acting upon the armature that becomes negative beyond a certain excitation of the electromagnet, and to reduce the trigger power for the electromagnet, a magnetic opposite pole is disposed on the side of the armature remote from the working air gap, forming a second working air gap, which is coupled to the magnet housing, optionally via a stray air gap, via a flow guide element annularly engaging the permanent magnet.
