<p>A vacuum vane pump is proposed which is driven by an internal-combustion engine (19). The pump has oil flowing through it which serves as a sealant and lubricant in a pump. A chamber (14, 15) of the pump is connected via an intake line (17) to the oil sump (20) of an internal-combustion engine (19), so that the pump can draw in the oil from the oil sump (20). Via a radial groove (25), a working chamber of the vacuum vane pump is connected to the interior of the rotor. Thus sealant and lubricant is available in the vacuum vane pump immediately on start-up. The vacuum vane pump is designed for a vacuum servo brake for vehicles having a diesel engine as an internal-combustion engine. <IMAGE></p> |
