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.

Abstract: A solenoid valve having a valve housing in which a flexible diaphragm is accommodated, having a rocker for deforming the diaphragm, wherein a first orifice of a first fluid channel serves as a first valve seat against which the diaphragm is pressed in a sealing manner in the first functional position of the rocker and which valve seat is released by the diaphragm in the second functional position of the rocker, and further comprising a magnetic drive for moving a linearly movable armature part which is provided with an intermediate part for transmitting force to the rocker and which passes through the intermediate part, wherein the intermediate part is connected to the end region in a force-locking and/or substance-locking manner and/or is supported in a form-locking manner on an annular collar of a retaining part fixed to the end region in a force-locking or substance-locking manner.
