Abstract

955,396. Valves. SOC. D'ETUDE ET DE CONSTRUCTION DE MATERIEL POUR L'AUTOMATISATION. June 14, 1961 [June 20, 1960], No. 21442/61. Heading F2V. A valve controlling high frequency intermittent passage of gas has a port 25 connectible to an inlet 2 via metallic seat 24 or atmosphere via metallic seat 26 according to the position of a synthetic resin closure member 3 e.g. made of a polyamide, polytetrafluoroethylene, or polyundecanamide, having a conical seating of semi-apex-angle greater than the angle of friction between the member and its seat, the resin having a maximum hygroscopicity in atmospheric air of 3.5% at relative humidity of 65%, a modulus of elasticity between 40 and 160 kg/mm.<SP>2</SP>, a maximum coefficient of friction on polished steel of 0.2 and a specific gravity at most 2.3. Gas pressure plus spring 4 loads the valve on seat 24 and connected piston 5 upwardly into cylinder 7 when cylinder gas pressure exhausts through passages 23, 9, 19, 21. On energizing solenoid 17, armature 16 is lifted against spring 12 away from stem 18 of pilot valve 8 which is lifted by inlet pressure at 10 to close atmospheric seat 20 and open seat 11 for inlet pressure to pass via 23 and move piston and valve 3 downwards to close seat 26 and allow inlet gas to press seat 24 to port 25. Valve 3 may be replaced by a valve below seat 26 and a valve above seat 24 formed by a piston extension.
