Abstract (en)
[origin: EP1193396A2] An automotive vane-type vacuum pump restrains seizure from taking place between an axial end surface of a rotor and a case, thereby permitting improved durability. The automotive vane-type vacuum pump for forcibly feeding a fluid from an inlet to an outlet includes a bottomed cylindrical case having an inlet and an outlet, a rotor eccentrically accommodated in the case, a shaft that is secured to the rotor, having both ends thereof rotatably supported by both bottom surfaces of the case, and rotates the rotor by an external driving force, and a vane that rotates slidably in contact with the inner peripheral surface of the case while moving in and out of the rotor as the rotor rotates. The axial movement of the shaft is restricted by slidable contact between axial movement restricting stepped portions provided on both ends of the shaft, and the case. Furthermore, a very small gap is formed between an axial end surface of the rotor and the case. <IMAGE>
