Abstract

1,206,721. Valves. HOUILLERES DU BASSIN DU NORD ET DU PAS-DECALAIS. 2 Jan., 1968 [3 Jan., 1967; 11 Aug., 1967], No. 266/68. Heading F2V. A pressure relief valve comprises a deformable plastics member 3 having a through passage 4 normally closed at 4a under the action of a loading pressure in chamber 5. The loading pressure is admitted via check valve 13 or, in the case of Fig. 2, by fitting a temporary bung 17 in a head 16 of member 3 so that fluid admitted to passage 8 can unseat head 16 and pass to chamber 2. A pair of semi-cylindrical metal reinforcing members (18) may surround the central region of member 3, and a solid (21) or hollow (23a) mandrel may pass through member 3, the hollow mandrel having radial holes extending from blind end passages therein and member 3 functioning to normally close these holes.
