Abstract

La présente invention concerne les électro-pompes. La pompe à vide 14 est entraînée par un unique servo-moteur électrique 12. La pompe à vide comprend un piston 194 associé à une membrane du type à enroulement de lobe 210. Le servo-moteur comprend une armature de contact 34 et une armature de sortie 74 déplaçables l'une par rapport à l'autre, l'armature de contact portant, à une extrémité, un contact 38 susceptible de venir coopérer avec un contact 91 formé sur un bras élastique extérieur 78 pour établir sélectivement un passage de courant d'excitation de l'enroulement 132 du servo-moteur. Une liaison à rotule sphérique 118 est prévue entre l'extrémité de l'armature de sortie et la tige 120 du piston 194. Le niveau de vide dans la pompe peut être déterminé par un écrou 234 de tarage d'un ressort de traction 228 de l'équipage de piston. Application à des systèmes de pompage automatiques à calage de degré de vide.The present invention relates to electro-pumps. The vacuum pump 14 is driven by a single electric servomotor 12. The vacuum pump comprises a piston 194 associated with a membrane of the lobe winding type 210. The servomotor comprises a contact armature 34 and a pressure armature. output 74 movable relative to each other, the contact armature carrying, at one end, a contact 38 capable of cooperating with a contact 91 formed on an external elastic arm 78 to selectively establish a current flow d excitation of the winding 132 of the servo motor. A spherical ball joint 118 is provided between the end of the output armature and the rod 120 of the piston 194. The vacuum level in the pump can be determined by a nut 234 for setting a tension spring 228 of the piston crew. Application to automatic pumping systems with vacuum degree setting.
