Abstract

A valve for controlling a fluid flow, including a valve housing, which is provided with a first fluid connection, a fluid channel and a second fluid connection, further including a valve member which is pivotally mounted in the fluid channel, and a drive for introducing a movement onto the valve member, the valve member having a rigid carrier and a flexible membrane with a sealing region which is provided for a sealing abutment against a valve seat and which is fixed to the carrier and to the valve housing by a circumferentially formed fastening region, wherein a deformation region of the flexible membrane is located between the sealing region and the fastening region and is arranged between a first deformation plane and a second deformation plane, the first deformation plane and the second deformation plane each being aligned parallel to a pivot axis determined by the pivot pin and delimiting a deformation space, and wherein the pivot pin is accommodated at least partially in the deformation space.
