摘要

The explosion protection valve (1) involves a housing (2) in which is at least one closure body (4) guided on a guide rod (3) and from an open position predefined through spring force by a pressure or suction shaft is displaceable in at least one movement direction against the spring force into a sealing position. On the guide rod is at least one spring component (5) producing spring force and held in the tensioned position between two limiting components. The closure body is in effective connection with the spring component via at least one driver component. In the event of a displacement of the closure body, the spring component, via the driver component, is further pressed together after overcoming the tension force.
