Abstract: A multiport valve, having a housing having at least two connectors, a control element for blocking at least one of the connectors, the control element disposed to be rotatable in a recess of the housing. An external contour of the control element has a compression portion which in at least one first position of the control element compresses a first seal disposed on a first one of the connectors. The external contour of the control element has a decompression portion that has a smaller radius than the compression portion and in at least one further position of the control element lies opposite the first seal such that the control element compresses the first seal to a lesser extent than in the first position.

Abstract: A seal arrangement for a fluid valve has: a first sealing element configured to bear sealingly against a valve housing of the fluid valve; a second sealing element configured to bear sealingly against an adjustable, rotatable, valve body of the fluid valve; and an elastically deformable intermediate piece arranged, axially, between a first wall of the first sealing element, which faces the second sealing element, and a second wall of the second sealing element, which faces the first sealing element, so as to elastically space apart the first and second sealing elements. In at least one axial portion of the intermediate piece, an axial cross section of the intermediate piece has a first radial lateral surface and an opposite second radial lateral surface. The first radial lateral surface is convex and the second radial lateral surface is concave, planar or less convex than the first radial lateral surface.

Abstract: A fluid valve, in particular for a motor vehicle and/or a temperature control system, having a housing and a valve body disposed in the housing so as to be rotatable about a rotation axis. The housing has a first port and a third port disposed on opposite side of a normal plane in relation to the rotation axis and a second port which is radially spaced apart from the rotation axis and in the direction of the rotation axis is disposed between the first and the third port. The valve body in at least one rotary position connects at least two ports of the housing to one another, and in at least one other rotary position does not connect the two ports to one another.

Abstract: A seal for use in a fluid control valve includes: a first, elastically deformable, plastic part; and a second plastic part configured as a hard seal element and connected to the first plastic part. The first and the second plastic parts form a seal assembly having a first frontal end configured to bear in a sealing manner on an actuatable valve body of the fluid control valve, and a second frontal end configured to bear in a sealing manner on a valve housing of the fluid control valve, wherein at least the first frontal end has a first end side having an encircling projecting bead configured to seal against the actuatable valve body.
