Abstract

A fluid switchover device includes a housing having at least three ports leading into an interior space; a valve flap rotatably arranged within the housing and having a rotational axis that is mounted to the housing at first and second locations; and a circumferential seal mounted to the valve flap and having first and second evasion portions at first and second locations, respectively, which are configured to evade the rotational axis on the same side of the valve flap, and the valve flap is configured to slidingly engage a boundary of the interior space by means of the circumferential seal, so that at a first position of the valve flap, the first and second ports are connected, and the first and third ports are mutually sealed off, and in a second position, the first and third ports are connected, and the first and second ports are mutually sealed off.
