Abstract: Various aspects of the invention are directed to a triggering device for a quickly triggering extinguishing system for explosion suppression. In some embodiments of the present disclosure, the triggering device may include a pawl body having a pawl flank, a catch, at least one electromagnet to transmit an electromagnetic field, and a sliding pin. The sliding pin triggers an extinguishing system for explosion suppression by movement from a blocking position into a release position. In the blocking position, the sliding pin is pushed against the pawl flank of the pawl body by means of the catch and is held in the blocking position by said pawl flank. The pawl body releases the engagement of the catch and the pawl flank, and thereby releases the sliding pin, in response to the at least one electromagnet exerting the electromagnetic field on the pawl body.

Abstract: Various embodiments of the present disclosure are directed to packing rings. In one example embodiment, a packing ring is disclosed including first and second axial ring ends, at least three ring segments, and at least three relief openings. The at least three relief openings each have a first relief opening end opening into the radially inside inner circumferential surface of the ring segment. The first relief opening ends of two relief openings arranged adjacent to one another in the circumferential direction are spaced apart from one another at a relief opening circumferential distance. The first relief opening ends are closer in the axial direction to the first axial ring end than to the second axial ring end and are spaced apart at a relief opening axial distance from the first axial ring end, which is 4% to 20% of the axial ring width of the ring segment.
