Abstract

a. Pompe à piston. b. Un groupe de pistons maintenus par un bloc cylindrique et un support cylindre tournent autour de la périphérie conique d'un pivot excentrique chaque ouverture cylindrique étant ainsi reliée alternativement aux rainures arguées ménagées sur la périphérie conique du pivot, en imprimant à chaque piston un mouvement de va-et-vient vers l'avant et vers l'arrière dans les ouvertures cylindriques de façon à produire une action de pompage. c. Pompe à piston qui peut être utilisée à la place d'une pompe à plongeur axial classique.at. Piston pump. b. A group of pistons held by a cylindrical block and a cylinder support rotate around the conical periphery of an eccentric pivot, each cylindrical opening thus being connected alternately to the argued grooves formed on the conical periphery of the pivot, imparting to each piston a movement of back and forth back and forth in the cylindrical openings to produce a pumping action. vs. Piston pump which can be used in place of a conventional axial plunger pump.
