The present invention relates to an automotive vacuum pump (10). The vacuum pump (10) has a casing (12) defining a cavity having an inlet (14) and an outlet (16), wherein the cavity contains a rotor (18) and a vane slidably mounted to the rotor (18). The rotor (18) extends through a side (21) of the casing (12) to the exterior thereof and is provided with a coupling arrangement (26) to couple the rotor (18) to a drive member. The vacuum pump (10) is provided with a lubrication conduit (50,56,66,68,70,72,74) for the supply of lubricating fluid to the coupling arrangement (26), the conduit (50,56,66,68,70,72,74) including a portion (70,72,74) which extends through the rotor (18) and the coupling arrangement (26). |
