Title (EN) SINGLE VANE ROTARY VACUUM PUMP WITH OIL SUPPLY PASSAGE CHANNEL
(FR) POMPE À VIDE ROTATIVE À AUBE UNIQUE DOTÉE D'UN CANAL DE PASSAGE D'ALIMENTATION EN HUILE
Abstract:
(EN) The invention provides a sliding contact single vane rotary vacuum pump in which an oil supply passage is placed in the centre of the rotating vane through which a lubricating oil flows, which provides oil distribution in the pump chamber with enhanced suction pressure of 39%; and the torque exertion by 2.86 - 7.63%, this helps in reducing the torque of the pump during maximum vacuum condition and results in reduction of the power consumption of the vacuum pump which in-turn decreases the net load on the automotive engine, thus reduces the peak torque, the pump internal chamber pressure and also results better vacuum suction performance.
(FR) La présente invention concerne une pompe à vide rotative à aube unique à contact coulissant dans laquelle un passage d'alimentation en huile est placé au centre de l'aube rotative à travers laquelle s'écoule un huile lubrifiante, qui assure une distribution d'huile dans la chambre de pompe avec une pression d'aspiration améliorée de 39 %, et augmente le couple exercé de 2,86-7,63 %, ce qui aide à réduire le couple de la pompe pendant une condition de vide maximum et entraîne une réduction de la consommation d'énergie de la pompe à vide qui, à son tour, diminue la charge nette sur le moteur automobile, ce qui réduit le couple de crête, la pression de la chambre interne de la pompe et conduit également à une meilleure performance d'aspiration sous vide.
