PRESSURE EQUALIZATION DEVICE, METHOD FOR PRESSURE EQUALIZATION AND HOUSING

A pressure equalization device for a housing has a base body and a closure element with a flow path between them being open in a normal operating state of the pressure equalization device. A flow opening in the flow path is spanned by a membrane. An emergency venting spike projects from the closure...

Zusammenfassung:	A pressure equalization device for a housing has a base body and a closure element with a flow path between them being open in a normal operating state of the pressure equalization device. A flow opening in the flow path is spanned by a membrane. An emergency venting spike projects from the closure element toward the membrane. The pressure equalization device transitions after emergency venting into an emergency operating state in which the closure element gas-tightly closes the base body. A housing with such a pressure equalization device is provided. In a method for pressure equalization with such a pressure equalization device between a housing interior and an environment, gas exchange between interior and environment is performed through the membrane and the flow path between closure element and base body. During emergency venting, the membrane is destroyed by the emergency venting spike. The closure element then closes the base body.
