Abstract: A gas cabinet has a housing receiving at least one gas bottle. The housing has at least one intake opening and at least one exit opening. A conduit system is located in the housing to which the at least one gas bottle is to be connected. A scavenging air passage for a scavenging air flow entering the housing through the at least one intake opening and exiting from the housing through the at least one exit opening is provided. The gas cabinet is configured such that an open flow cross-section of the air passage for the scavenging air in the housing is limited to an amount necessary for a reliable scavenging action. At least one displacement body is arranged in the housing for limiting the flow cross-section in the housing.

Abstract: An ignition coil of an ignition system in an internal combustion engine has a housing, a magnetically active core, a first coil winding connected to a supply voltage, and a second coil winding connected to a high-voltage terminal. At least one electrically conductive component is provided, at least in some areas, with a means for an electrically effective evening out of its surface.

Abstract: A magnetic circuit for an ignition coil or a transformer, including an inner, essentially rod-shaped core and an outer core. The outer core includes a strip-shaped element of thickness, length and width, and is situated around the inner core in such a way that the strip-shaped element is positioned at the faces of the inner core with its thickness perpendicular to the longitudinal direction of the inner core.
