Abstract

La présente addition concerne des perfectionnements ou modifications à la pompe du brevet principal. La pompe objet de présente addition comprend essentiellement un piston 2 sollicité par un organe poussoir 3 et une embase 4 formant cuvette d'assise pour un ressort de rappel 5 du piston 2. L'embase 4 est solidaire de l'organe poussoir 3 ou invariablement liée à celui-ci et comporte une partie creuse 14 sensiblement en forme de cloche dont la paroi latérale 15 comporte des orifices de communication 6, 7 entre le premier espace 8 formé au dessus de l'embase 4 et un deuxième espace 9 formé en dessous de l'embase, et un clapet 10 unique destiné à fermer l'ouverture inférieure 16 de la partie en cloche 14. Le clapet 10 est de préférence coaxial à l'embase et constitué par un disque 17 élastiquement déformable par flexion obturant l'ouverture 16 en position de repos, à l'état non déformé. Cette pompe d'injection est applicable à tous les types de pompe utilisées dans les moteurs à combustion interne.The present addition relates to improvements or modifications to the pump of the main patent. The pump object of this addition essentially comprises a piston 2 biased by a pusher member 3 and a base 4 forming a seat bowl for a return spring 5 of the piston 2. The base 4 is integral with the pusher member 3 or invariably linked thereto and comprises a hollow part 14 substantially bell-shaped, the side wall 15 of which has communication openings 6, 7 between the first space 8 formed above the base 4 and a second space 9 formed below of the base, and a single valve 10 intended to close the lower opening 16 of the bell-shaped part 14. The valve 10 is preferably coaxial with the base and consists of a disc 17 elastically deformable by bending closing the opening 16 in the rest position, in the undeformed state. This injection pump is applicable to all types of pump used in internal combustion engines.
