Abstract
A fluidic control element has a housing that is assembled from first and second housing parts. A control space is formed between the housing parts into which two flow ducts open that are located in the first housing part. A sealing seat is arranged in the control space and is assigned to one of the flow ducts. A diaphragm is clamped between the housing parts. An actuating rocker element mounted for pivotal movement in the second housing part is configured with two lever arms, is movable between an opening position and a closing position, and is firmly attached to the diaphragm in an attachment area opposite the sealing seat. The actuating rocker element is provided with supporting areas for the diaphragm that are adjacent to the attachment area.
