Zusammenfassung:A device in a valve includes a valve housing with at least a first and a second fluid port. A closure element including a sealing portion and a diaphragm is arranged in the valve housing. The sealing portion is movable between an open position and a closed position. The closure element and valve housing form a flow passage which communicates with the fluid ports when the sealing portion leaves the closed position. A second sealing portion is arranged in contact with a support portion of the valve housing. An abutment element is arranged in contact with the second sealing portion. The abutment element transmits a force via the second sealing portion toward the support portion to provide a seal. The force is at least partly exerted by a spring element.
