| Zusammenfassung: | A combined pressure cutoff and pressure relief valve includes a normally closed switch movable between closed and open contact positions. A normally closed pressure relief vent is located in a common housing with the switch. A pressure responsive diaphragm applies force to a switch snap disc and a vent snap disc. Under high pressure conditions, the switch snap disc snaps and opens a pair of contacts. In the event an abnormal pressure condition occurs, the vent snap disc operates and causes a pin to rupture the diaphragm for opening the relief vent. |
