摘要： Actuateur rotatif (10) possédant un boîtier (12) qui définit une chambre arquée et qui comprend une première partie monolithe (12A) renfermant entièrement la chambre arquée, un piston (30) disposé dans le boîtier pour un mouvement alternatif dans la chambre arquée, un arbre (34) à tourillon monté dans le boîtier, relié au piston et tournant en réaction au déplacement du piston, un ensemble d'étanchéité libre (28) porté par le piston ou par le boîtier afin d'assurer l'étanchéité entre ceux-ci, un orifice d'entrée (64) de fluide sous pression servant à introduire un fluide dans le boîtier afin de déplacer le piston dans un premier sens, ainsi qu'un dispositif à pression fluidique (62) ou à ressort de rappel servant à déplacer le piston dans un deuxième sens contraire au premier. Dans un mode de réalisation préféré, l'actuateur emploie un mécanisme à ressort de rappel (106) qui communique à l'arbre une force de torsion sensiblement constante en fonction du déplacement dudit mécanisme entre une première position comprimée et une deuxième position relâchée de sorte que la force de torsion agissant sur l'arbre (34) dans les deux sens de rotation soit semsiblement constante.

摘要： L'invention concerne une vanne de recirculation à basse pression , destinée à refroidir une pompe centrifuge. Une structure de vannes (12) comporte une première chambre (14) dotée d'une admission (18) et d'un orifice de recirculation (22), ainsi qu'une seconde chambre (16) dotée d'une sortie (20). Un clapet de non retour (36) à pièces multiples, situé entre les première et seconde chambres, permet l'écoulement de ladite première à ladite seconde chambres, et empêche l'écoulement dans le sens opposé. Une tige de vanne coulissante (23) est acouplée audit clapet de non retour, laquelle s'étend dans ladite première chambre et déplace ledit clapet de non retour de sa position ouverte à sa position fermée. Un moyen (42) accouplé audit clapet de non retour sollicite la tige de vanne coulissante ainsi que ledit clapet de non retour vers la position fermée. Un moyen de vanne de recirculation (31-35-35a) couplé fonctionnellement à ladite tige de vanne, ouvre et ferme ledit orifice de recirculation, ledit moyen de vanne de recirculation s'ouvrant lorsque ledit clapet de non retour est fermé et se fermant lorsque ce dernier est ouvert.

摘要： A manifold assembly (10) for operating a safety relief valve (12) includes a manifold block (60) having a block inlet port (230), a block dome pressure port (232), and a pair of control cavities (220 and 222) each adapted for receiving a pilot valve (70) or auxiliary control member (80). Inlet control valves (74, 84) dome pressure control valves (76, 86) and test control valves (78, 88) are each mounted on the manifold block. One of the pilot valves may be maintained on-line for controlling operation of the safety relief valve, while the other pilot valve may be isolated for service. A cartridge pilot valve assembly (70) includes a bushing (126) for facilitating installation and removal of the cartridge valve assembly from the valve block. An improved metal washer (122) is provided having inner and outer knife edges (330, 334) for sealing engagement between the valve body (110) and the block (60).

摘要： A pilot operated safety relief valve for a vent (16) in a pressure vessel (10) is described which comprises: a value housing (142) mounted on said pressure vessel (90) over said vent (16) and defining a main valve chamber (156) in continuous fluid communication with said vent (16) and said pressure vessel (10); a valve seat (166) in said main valve chamber (156) defining an outlet for said valve chamber (156); a main valve member (172) mounted on said valve seat (166) adjacent one end of said valve chamber (156) for reciprocable movement between a seated closed position on said valve seat (166) and an unseated open position relative to said valve seat (166); an operating rod (174) secured adjacent one end to said main valve member (172); fluid pressure responsive means operatively connected to the other end of said operating rod (174) adjacent the other end of said valve chamber (156) responsive to a predetermined fluid pressure in said pressure vessel (10) and said valve chamber (156) to permit movement of said main valve member (172) to an open position, said fluid pressure responsive means comprising a fluid responsive member (176) connected to the other end of said rod (174) and defining an inner fluid chamber (182) on one side of said fluid responsive member (176) adjacent said valve member (172) and an outer fluid chamber (186) on the other side of the fluid responsive member (76) remote from said valve member (172), and a pilot valve (190) in fluid communication with said inner fluid chamber (182) for normally controlling the opening and closing of said main valve member (172), said main valve member (172) being continuously urged to an open position by fluid pressure from said pressure vessel (10). The outer fluid chamber (186) in one embodiment is in communication with atmosphere. In another embodiment it is in fluid communication with said pressure vessel (1) to assist in opening of said main valve member (172c), In that case there is also means providing fluid communication between said inner fluid chamber (182c) and said outer fluid chamber (186c) under predetermined operating conditions to permit and equalization of fluid pressure in said inner and outer fluid chambers (182c, 186c).
