Abstract: A control device for a fluid is described, having a housing, a first opening, a second opening, a channel running from the first to the second opening and a movable control element, which is pivotable between a closed position and an open position. The first opening of the control device forms an assembly opening, through which the control element can be installed in the housing.

Abstract: This disclosure pertains to a control device for the coolant flow in a cooling circuit of an internal combustion engine with the following characteristics: a housing with an inlet opening, an outlet opening and a movable control element for varying the flow-through cross section of the channel; an annular seal arrangement comprising a sealing frame and a sealing ring is seated between a sealing surface of the housing and a sealing surface of the control element. According to this disclosure, it is proposed that the sealing ring rests against a plane sealing surface of the housing in a sealing fashion and meets this plane sealing surface along a contact line that encloses a first surface area. Depending on the flow direction through the seal arrangement, the sealing ring features a surface section that has a defined circumference referred to the length of the contact line between the sealing ring and the housing.
