Title (EN) SUCTION PORT LOCK NUT WITH STUB BUTTRESS THREADS
(FR) ECROU DE BLOCAGE D'ORIFICE D'ASPIRATION AYANT DES FILETS D'ERGOT EN DENTS DE SCIE
Abstract:
(EN) A reciprocating pump assembly having a block body, a cylinder chamber in the block body, a plunger recϊprocatingly disposed in the block body, an opening in the block body adjacent the cylinder chamber, and a cover plate in the opening. Threads on the outer periphery of the cover plate engage threads formed within the opening. The threaded outer periphery of the cover plate extends into the cylinder chamber and past the threaded portion of the opening so thai the load on the cover plate transfers from fully formed threads on the cover plate to threads formed on the opening.
(FR) La présente invention porte sur un ensemble pompe à mouvement alternatif ayant un corps de bloc, une chambre cylindrique dans le corps de bloc, un piston disposé selon un mouvement de va-et-vient dans le corps de bloc, une ouverture dans le corps de bloc adjacente à la chambre cylindrique, et une plaque de recouvrement dans l'ouverture. Les filets sur la périphérie externe de la plaque de recouvrement sont en prise avec les filets formés dans l'ouverture. La périphérie externe filetée de la plaque de recouvrement s'étend dans la chambre cylindrique et après la partie filetée de l'ouverture de telle sorte que la charge sur la plaque de recouvrement soit transférée des filets complètement formés sur la plaque de recouvrement aux filets formés sur l'ouverture.
