Abstract: An electromagnetically compatible housing device for a high-voltage battery of a vehicle, having: a first housing part which shields electromagnetic radiation and has an electrically conducting contact face, and a second housing part which is in the form of a spring part and shields electromagnetic radiation and which is connected in an electrically conducting manner to the electrically conducting contact face of the first housing part and is configured to establish electrically conducting contact with a battery housing part of the high-voltage battery.

Abstract: A fuel cell arrangement has an anode connected to an H2 inflow and a cathode connected to an O2 inflow. A differential pressure control device is arranged between the H2 inflow and the O2 inflow for controlling a differential pressure between the H2 inflow and the O2 inflow. The differential pressure control device has a fluid connection between the H2 inflow and the O2 inflow, in which a deflectable diaphragm is arranged, to which a pin is coupled, which, when the diaphragm is deflected, opens a valve arranged in the H2 inflow.

Abstract: The invention relates to a fuel cell arrangement (10) having an anode (26) connected to an H2 inflow (48) and a cathode (30) connected to an O2 inflow (50), wherein a differential pressure control device (52) is arranged between the H2 inflow (48) and the O2 inflow (50) for controlling a differential pressure between the H2 inflow (48) and the O2 inflow (50), the differential pressure control device (52) having a fluid connection (54) between the H2 inflow (48) and the O2 inflow (50) in which a deflectable diaphragm (56) is arranged, to which a pin (64) is coupled which, when the diaphragm (56) is deflected, opens a valve (58) arranged in the H2 inflow (48).

Abstract: The present disclosure relates to high-pressure fuel pumps and the teaching may be applied to pumps in which a pump piston, by means of which a fuel is acted on with a high pressure, is guided in a guiding sleeve. In some embodiments, a high-pressure fuel pump may include: a housing having a housing recess; a pump piston for pressurizing a fuel; and a guiding sleeve arranged in the housing recess and guiding the pump piston. The guiding sleeve is connected to the housing recess with a materially engaging connection.

Abstract: A damper for a high-pressure pump includes a housing and a cover that can be coupled to the housing to form a damping space. The cover has an elevation including a plurality of concave regions and a plurality of convex regions, wherein the concave and convex regions are arranged about a central region of the elevation. Each of the concave regions is arranged between two of the convex regions in order to scatter sound.
