Abstract

La présente invention a pour objet un mécanisme d'entraînement pour une pompe alternative à débit mesuré Un organe d'entraînement à mouvement alternatif 7 est actionné par un toucheau de came 5 coopérant avec une came 3 portée par un arbre rotatif d'entrée 2 à l'aide d'une liaison à perte de course 18, 19 entre le toucheau de came 5 et l'organe d'entraînement à mouvement alternatif 7 et d'un matériau amortisseur 17 légèrement élastique entre le toucheau de came et l'organe d'entraînement 7, le matériau amortisseur étant, de préférence, maintenu dans un état de pré-compression même pendant le retour de course; le matériau amortisseur sert à absorber l'énergie du début de l'entraînement dans la liaison à perte de course et il améliore la douceur et le silence à perte de course et il améliore la douceur et le silence de fonctionnement de la pompe.The present invention relates to a drive mechanism for a reciprocating pump with a measured flow rate. A reciprocating motion drive member 7 is actuated by a cam bearing 5 cooperating with a cam 3 carried by a rotary input shaft 2 to using a loss-of-stroke connection 18, 19 between the cam bearing 5 and the reciprocating drive member 7 and a slightly elastic damping material 17 between the cam bearing and the member d drive 7, the damping material preferably being maintained in a state of pre-compression even during the stroke return; the damping material serves to absorb the energy at the start of the drive in the loss-of-stroke linkage and it improves smoothness and silence at loss of stroke and it improves the smoothness and quietness of the operation of the pump.
