Abstract (en)
[origin: WO2014102650A1] A lubrication system (200) for a rotary vacuum pump (300) connectable to a thermal engine comprises a suction duct (50) connecting the pump (300) to a power brake (16), and a connecting duct (23) connecting the inside of the engine with the suction duct (50) in order to generate, through the connecting duct (23), a flow of an air-oil mixture sucked from the inside of the engine. The invention also concerns a pump having a casing (40) which defines a pumping chamber (44) and a connecting duct (23) formed in the casing (40), and a lubrication method for such a pump.
