Abstract

L'invention concerne les suspensions des moyens de transport tels que les automobiles. Le ressort pneumohydraulique faisant l'objet de l'invention est caractérisé notamment en ce qu'on a pratiqué une rainure circulaire 19 sur la surface intérieure du corps 11 de la pompe 10 à plongeur, solidaire de la tige 6, alors que le plongeur 12 de la pompe 10 est pourvu d'un épaulement annulaire 20 disposé sur sa surface extérieure et formant avec la rainure circulaire 19 du corps Il deux enceintes annulaires D et E communiquant constamment, l'une D avec le réservoir 16 à liquide, et l'autre E, avec l'enceinte A au-dessus du piston du cylindre 1, dans laquelle s'engage l'extrémité du plongeur 12. L'invention permet la mise en action périodique de la pompe à plongeur au fur et à mesure de l'augmentation des fuites d'huile de l'enceinte située au-dessus du piston.The invention relates to the suspensions of means of transport such as automobiles. The pneumohydraulic spring forming the subject of the invention is characterized in particular in that a circular groove 19 has been made on the inner surface of the body 11 of the plunger pump 10, integral with the rod 6, while the plunger 12 of the pump 10 is provided with an annular shoulder 20 disposed on its outer surface and forming with the circular groove 19 of the body II two annular enclosures D and E constantly communicating, one D with the liquid reservoir 16, and the another E, with the enclosure A above the piston of the cylinder 1, in which the end of the plunger 12 engages. The invention allows the periodic activation of the plunger pump as and when 'increased oil leaks from the chamber above the piston.
