Compact miniature fire-extinguishing and/or fire-protection device

A passively thermally controlled trigger valve of a fire extinguishing or fire protection device, wherein the trigger valve comprises

• a bearing part;
• a triggering part that is movable relative to the bearing part between a standby position and a triggering position;
• a perforation element arranged on the triggering part;
• a spring arranged between the bearing part and the triggering part which pretensions the triggering part relative to the bearing part in the triggering position;
• a support bearing for the spring arranged on the triggering part;
• and
• a thermal triggering element which holds the triggering part in the standby position against the pretensioning exerted by the spring;
• wherein the triggering part at least in one section forms a sleeve section that surrounds and is seated on the bearing part and is moveable in a longitudinal direction of the bearing part on the bearing part between the standby position and the triggering position;
• wherein the support bearing is formed by a bearing pin attached to opposite wall zones of a section of the triggering part and extending perpendicular to the longitudinal extension of the triggering part wherein the bearing pin passes through guide slots in the bearing part.
