<p>Regulating insert,chiefly for insertion in a valve housing or the like in a flowing medium,comprising a pre−setting for regulation and/or setting of amounts of liquid in installations with flowing media for the limitation of the medium to a pre−set maximum amount,independently of a differential pressure working across the valve,said insert further comprising a tubular regulating element which is displaceable in a housing(3)in the longitudinal direction of the regulating insert,and lies up against a spring element(13)so that upon displacement the tubular regulating element(2)respectively opens or closes a number of openings(9)in the housing(3),where said tubular regulating element(2)is influenced for regulation by a membrane,where the membrane(14)is a roller membrane,said roller membrane(14)being fastened along an outer diameter to the inner side of the housing(3)and along an inner diameter is fastened to the outer surface of the regulating element(2),so that the resulting forces stemming from the differential pressure across the membrane(14)lie on the same cylinder surface as that which extends through a slide surface(12)between the largest diameter of the regulating element(2)and the smallest diameter of the housing(3).</p> |
