Abstract
A fluid control element has a housing (10), a fluid control space (12) formed in the housing and into which at least two flow ducts (16) open, at least one sealing seat (14) arranged in the fluid control space (12) and associated with one of the flow ducts and a movable lug (30) extending into the fluid control space (12), the lug (30) being encased in an elastic material and being able to cover the sealing seat and constituting one arm of a reed. Furthermore, two rotary joints are provided for the reed which are formed by a tightly surrounding casing which is fashioned of the elastic material and is held in the housing. The second arm of the reed extends out from the control space (12) as an actuating arm (22). The two rotary joints arranged opposite to one another transversely in relation to a longitudinal direction of the lug (30) in opposite housing walls with the result that the control element may be moved independently from the pressure in the fluid control space (12).
