Abstract

777,147. Regulating fluid flow. CLIMAX ROCK DRILL & ENGINEERING WORKS, Ltd. Dec. 8, 1954, No. 35574/54. Class 135. A device for maintaining a substantially constant flow of fluid comprises a resilient tube 5 anchored at its ends and subject on its outer surface to the upstream pressure whereby the tube is radially deformed inwardly in accordance with the pressure head. In Fig. 1, a rubber tube 5 is held in tension on bosses 21 by clamping rings 22. The bosses are formed on end discs 19, 20 fitted to a sleeve 18 having a lateral slot 24 to allow the tube 5 to be mounted. The parts 18, 29, 20 are held against a rubber washer 25 in a body member 1 by a circlip 8. The inlet pressure has access to the outside of the tube through apertures 23. In a modifica. tion, the rubber tube is closely surrounded by a perforated rigid tube and its ends are curled back over the ends of the rigid tube. The maximum flow may be limited by a constrictor comprising a slotted disc 28, Fig. 5, fitted into a slot in the body 1 so as to deform the rubber tube to an oval shape. Discs with different sized slots may be used.
