摘要： The invention concerns an oil-sealed vane-type rotary vacuum pump (1) with a rotor (3) and an oil pump (45, 46) whose suction chamber is fitted with feeds (64, 65) for gas and oil. In order to simplify the supply of a gas/oil mixture to the vacuum pump, the invention proposes that the gas and oil feeds (34, 35) are disposed in such a way that initially only oil and subsequently both oil and air are aspirated into the volume swept by the oil pump (45, 46) as it rotates.

摘要： The invention pertains to a vacuum pump (1) with a closable line (63, 102) through which gas ballast can be fed into the pump chamber (8, 9). To eliminate the danger that a recipient hooked up to the vacuum pump may be charged with air in the event of a pump failure, the invention proposes that the line be equipped with a control valve (59, 60, 61; 98, 99; 109, 110) to regulate the gas ballast feed as a function of operating conditions, such that the line is closed in the event of a pump failure.

摘要： The invention concerns a seal for a shaft (4) in a dividing wall (1) which separates an oil-containing space (2) from an oil-free space (3) by means of two sealing rings (13, 14). In order to provide a seal which is effective in both directions, the invention proposes that the sealing rings (13, 14) are located immediately next to each other, that their closed sides face each other and that the open side of the ring (14) facing the oil-free space (3) is fitted next to a chamber (15) filled with grease (16).

摘要： The invention concerns a method of operating an oil-sealed vacuum pump (1) with an outlet nozzle (8) provided with a flap valve (9), an oil feed duct (11) which has a valve (13) and has its outlet in the suction chamber of the pump, an electric drive motor (14) for the rotor (4) with coils (15 and 20), and a capacitor (16). The valve (13) in the oil feed duct (11) is closed when the pump (1) is switched off or in the event of a power cut. To ensure that a vacuum is maintained even when a mechanical fault occurs, it is proposed that the valve (13) in the oil feed duct (11) should be controlled by the rotational speed of the rotor (4) and drive motor (14) so as to remain open at normal operating speed and to close when speed is reduced; the auxiliary coil (20) of the motor can serve as a sensor.

摘要： The invention concerns an oil-sealed vane-type rotary vacuum pump with a suction chamber (8) housing a rotatably mounted rotor (3) which has an anchoring section (21) and a bearing section (23) with a slot (24) in which two vanes (26) are mounted with a gap (28) between them. The rotor bearing comprises the bearing section (23) and a rotor-mounting bore (11). The vacuum pump also has an oil pump (45, 46), which produces a flow of oil through the gap (28) between the vanes, and a system for controlling the flow of oil through the gap (28), the oil passing through a channel (66) opening out in the rotor-mounting bore (11) and then through radial and longitudinal bores (68, 69) in the bearing section (23) of the rotor. In order to reduce the noise produced by the pump when in operation, the invention proposes that the location where the oil channel (66) opens out into the rotor-mounting bore (11) and the location of the radial bore (68) in the bearing section (23) of the rotor, with respect to the location of the vanes (26) or the vane-mounting slot (24), are such that oil can only flow into the gap (28) between the vanes when the gap volume is increasing, and that there is a permanently open line leading to the vacuum-pump chamber (8) for the oil leaving the gap (28) between the vanes.
