Safety system for an apparatus for generating energy

Tribological system for use with e.g. magnetic valve, of e.g. internal combustion engine, has two friction partners that exhibit two-part layer with hard primary layer and outer sliding layer, where sliding layer is fixed lubricant layer

Valve i.e. gas injecting valve, for injecting gaseous fuel into internal-combustion engine, has stop unit limiting movement of valve unit in direction of valve seat, such that sealant seals between valve seat and unit in closed condition

Fuel cell system with a membrane unit for separating a hydrogen-enriched fuel from a hydrogen-containing mixture

Valve, particularly gas injection valve of internal combustion engine for controlling gaseous medium, has alve seat with spring element which takes pre-stressed position when valve is closed

Apparatus for converting energy that can be operated with fuel, in particular fuel cell assembly

Mit Brennstoff betreibbare Vorrichtung zur Wandlung von Energie, insbesondere Brennstoffzellenvorrichtung

Apparatus for controlling a fuel cell device, and a fuel cell device

Valve device for controlling fluid stream, e.g. volume flow of gaseous fluid, has damping area which is designed between stop surface and area attached to housing for absorbing kinetic energy of valve armature
