    摘要： A degassing unit to be connected fluid-tightly to a pressure compensation opening of an electronics housing has a base body with gas passage opening. A semipermeable membrane, fastened fluid-tightly to a membrane carrier, allows gaseous media to pass from an environment into the electronics housing and in reverse but prevents passage of liquid media and solids. In normal operation, the membrane covers the gas passage opening. An axial seal circumferentially extends about the gas passage opening. The membrane carrier is moveable relative to the base body and, in normal operation, is pressed by axial force seal-tightly against the axial seal. The membrane carrier, when a predetermined pressure difference between housing interior and environment is surpassed, lifts off the base body to release an emergency degassing opening surrounding the membrane. The axial seal is a lip seal and made of a material softer than a material of the membrane carrier.

    摘要： 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.

    摘要： A pipe component has a casing embodied as a folded bellows with folds. A tubular support body has an outer circumference and a length extension in a direction of a center line of the tubular support body. The tubular support body is embedded in the casing and supports the casing. The tubular support body has at least one stabilization element and the at least one stabilization element has segments that are axially spaced apart and at least partially extend circumferentially. The segments are connected by one or a plurality of hinges, respectively, along the length extension of the tubular support body. The hinges are arranged in the folds of the folded bellows of the casing.

    摘要： A filter element for filtering a fluid is provided with at least one filter bellows with a first areal inflow surface for a first fluid flow of the fluid and at least one second inflow surface for a second fluid flow of the fluid separate from the first fluid flow of the fluid. The at least one second inflow surface is separate from the first areal inflow surface. A flow channel section for the second fluid flow of the fluid is provided. At least one compensation element is arranged in the flow channel section for the second fluid flow of the fluid at a raw side of the filter element. A filter system with a filter housing is provided with such a filter element arranged exchangeably in the filter housing.
