Изобретение относится к вакуумной технике и позволяет повысить КПД, надежность, ресурс и эффективность насоса при обеспечении безмасляной откачки. Для этого в корпусе выполнены две расточки с размещенными в них двумя вытеснителями, установленными шарнирно на осях, на валу электродвигателя размещен кривошип, к которому шарнирно присоединены одним концом два рычага, другими концами рычаги шарнирно присоединены к вытеснителям.The invention relates to vacuum technology and can improve the efficiency, reliability, service life and efficiency of the pump while ensuring oil-free pumping. For this, two bores are made in the housing with two displacers placed in them, pivotally mounted on the axes, a crank is placed on the motor shaft, to which two levers are pivotally connected at one end, the levers are pivotally connected to the displacers.
