Shut-off member with rinsing

A shut-off member which comprises:

• a valve housing having an interior and at least one inlet and at least one outlet and a closure element, which is mounted rotatably about an axis in the interior, wherein between the closure element and the valve housing there is a free space for flow of a fluid between inlet and outlet and a pair of sealing surfaces is provided at the at least one inlet between valve housing and closure element, wherein the sealing surface of the closure element is pivotable through rotation of the closure element and in the locking position of the shut-off member shuts off the inlet by fluid-tight bearing against the sealing surface of the valve housing, the distance of the sealing surfaces from the axis or the centre point of the closure element is greater than the distance of the axis or the centre point to other outer regions of the closure element in order to form the free space which in the locking position is connected to the outlet in a fluid-conducting manner and/or
• that the distance of the sealing surfaces from the axis or the centre point of the closure element is shorter than the distance of the axis or the centre point to other regions of the valve housing interior in order to form the free space which in the locking position is connected to the outlet in a fluid-conducting manner.
