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： Disclosed is a hermetically closed battery degas venting unit for venting a battery enclosure/pack/housing having rechargeable vehicle batteries. The unit having a housing base equipped with a non-porous rupturable venting film closing over and sealing off the pressure venting opening. The non-porous venting film configured to deflect towards a spike in response to overpressure and to tear or rupture to release overpressure in the battery enclosure/pack/housing.

摘要： A filter element for filtering fluid has a filter bellows with a zigzag folded filter medium arranged in a reinforcement frame. A seal is arranged at least partially continuously at least in section at a circumferential side of the filter medium at a raw side inlet surface or clean side outlet surface of the filter bellows. Elongate adhesive sections are arranged along an unwinding of folds of the filter medium in adhesive tracks at an inflow side or outflow side, or both, of the folds. The adhesive tracks at the inflow side and outflow side are arranged offset in transverse direction of the filter medium. At least the adhesive tracks at the outflow side are designed to relieve tension for a length change compensation of the adhesive tracks at the outflow side in relation to filter medium and/or seal. A filter system with such a filter element is provided.

摘要： A particle discharge device for a filter assembly has a housing with a valve seat, wherein the valve seat surrounds at least partially a symmetry axis of the housing. One or more particle discharge flaps embodied as one piece together with the housing are provided. The one or more particle discharge flaps are moveable from a closed state into an open state for discharging particles from the filter assembly. The one or more particle discharge flaps are resting against the valve seat in the closed state. A filter assembly is provided with a filter housing having a particle discharge socket in which the particle discharge device is arranged.

摘要： A filter element for filtering a fluid has a frame and a filter bellows provided with a filter medium folded in a zigzag shape to folds. The filter bellows has an inflow face at a raw side of the filter bellows and an outflow face at a clean side of the filter bellows. The filter bellows is arranged in the frame. A seal is arranged circumferentially at least partially continuously at least in sections at an outer circumferential side of the filter medium at the inflow face of the filter bellows or at the outflow face of the filter bellows. Elongate adhesive sections are arranged along at least two adhesive tracks on the filter medium at the inflow face of the filter bellows and/or at the outflow face of the filter bellows. Strain-relief devices for compensating a length change of the at least two adhesive tracks in relation to the filter medium and/or to the seal are provided.

摘要： A separation device for separating liquid from gas has a separation element with housing, housing cover with housing cover thread, and filter element arranged therein. A first gas passage arranged centrally relative to a mounting axis of the separation element at a connector device has the housing cover thread assigned thereto. A second gas passage is arranged radially outside the first gas passage. A connection element connecting the separation element to the connector device has a conduit and a connection element thread to which the housing cover thread is screwed. A circumferential element adjoining the connection element thread extends axially into the separation element. Connection element thread and circumferential element surround the conduit. A fluid channel extends axially between conduit and circumferential element. A contour element of the separation element and a counter contour element of the connection element interact confusion-proof when screwing the separation element onto the connection element.

摘要： A filter element for filtering a fluid has a zigzag-shaped filter bellows with folds having parallel fold tips successively arranged in length extension of the filter bellows transverse to a vertical axis of the filter bellows. The fold tips extend between longitudinal sides of the filter bellows which are parallel to the length extension. The filter bellows is arranged in a continuous frame and surrounded by the continuous frame. The continuous frame has at least one first frame segment and at least one second frame segment, wherein the first frame segment has a hardness different from a hardness of the second frame segment. The first frame segment is formed of a first hard material and the second frame segment is formed of a second soft material. The filter bellows is fixed in the second frame segment. A filter system has such a filter element arranged in a filter housing.
