A membrane humidifier has a housing and a membrane stack. The membrane stack includes two first stack sides aligned parallel to the assembly direction. The membrane humidifier has a sealing device with two first sealing frames, each with an inner sealing surface and an outer sealing surface. The housing has two first housing sealing surfaces. The first sealing frames are in sealing contact with the inner sealing surfaces on the first stack sides. The first sealing frames are in contact with the outer sealing surfaces on the first housing sealing surfaces. The outer sealing surfaces of the first sealing frames and the first housing sealing surfaces of the housing are each aligned at a mounting angle to the first stack sides and to the mounting direction that is not zero. In addition, an arrangement is provided which includes the membrane humidifier and the sealing device for the membrane humidifier.

Membrane humidifier

A fluid conduit coupling may include a tubular body, a connecting piece, and a securing clamp radially adjustable relative to the tubular body between a securing position and a release position. The connecting piece may have a securing groove extending in the circumferential direction, the tubular body may have a securing slot aligned radially to the securing groove when the connecting piece is inserted into the tubular body, and the securing clamp may have a securing web sticking out radially to the inside, and, in the securing position, radially engages with the securing groove through the securing slot, and, in the release position, does not radially engage with the securing groove. The tubular body may have at least one guide groove, and the securing clamp may have at least one guide web sticking out radially and, at least in the securing position, radially engages with the associated guide groove.

Fluid conduit coupling having securing clamp

A hose arrangement for a motor vehicle may include a flexible elongated bellows including a plurality of radially orientated pleats and two axial longitudinal ends. The hose arrangement may also include at least one reinforcement rib which, on an outside, is coupled to a pleat tip of a respective pleat of the plurality of pleats in a material-bonded manner via two-component injection moulding. The at least one reinforcement rib may engage about the respective pleat in a circumferential direction. The at least one reinforcement rib may have at least two rib segments disposed following one another in the circumferential direction. Each of the at least two rib segments may radially cover the pleat tip by a segment angle of 30&#xb0; to 310&#xb0; in the circumferential direction.

Hose arrangement

A coupling device for connecting at least two fluid-conducting components may include a connector that may have a securing ring. A locking ring may be arranged on the connector and be configured to transition in a circumferential direction between a securing position and a releasing position. The locking ring may include at least one locking element configured to interact with the securing ring. The locking element may be configured resilient in a radial direction. A connecting piece may be configured axially adjustable with respect to the connector and may include an outer securing groove. The locking element may radially engage into the securing groove when the locking ring is in the securing position to secure the connecting piece to the connector in the axial direction.

Coupling device for a fresh air system

An exemplary air filter may include an air-permeable filter body for cleaning air, and a filter housing for holding the filter body. The air filter may also include a clean-air port fluidically connected to the filter body and mechanically connected to the filter housing for attaching the air filter to a clean-air channel. The air filter may further include a first air-flow grid arranged in the clean-air port to stabilize the filtered air.

Air filter

A filter element having a longitudinal center axis for a fresh air system of an internal combustion engine may include a first plate filter body composed of a pleated filter material and a separate second plate filter body composed of a pleated filter material. The filter element may include first wall body and a second wall body, and a first end body and a second end body. The first wall body, the second wall body, the first end body and the second end body may be connected to the first plate body and the second plate filter body to define an inner space. At least one of the first plate filter body and the second plate filter body may include a curvature projecting to the interior space in a profile extending transversely to a longitudinal direction with respect to the longitudinal center axis.
