なり、吐出口４部分にオイルが滞留する。In general, in a vacuum pump that performs this type of air discharging operation, when no air is being discharged and there is no load, the inside of the pump becomes a high vacuum relative to the external pressure (atmospheric pressure), making it difficult for lubricating oil to be discharged. Oil stays in some areas.

機能を損なうことも考えられる。(Problem to be solved by the invention) Then, the vane 5 passing through the discharge port 4 collides with the oil remaining in the discharge port 4, producing an impact, and the impact force increases at high rotation speeds, causing the vane to In addition, in order to supply vacuum to the vacuum control equipment 12 that utilizes other vacuum, such as idle up, which increases the idle speed of the engine, the vacuum pump A hose 7 is installed in the jet inlet 13 near the inlet 6 of the vacuum tank 12. For example, an abnormality caused by another device 12, such as a break in the hose 7, will directly affect the degree of vacuum in the vacuum tank IO, and the control booster It is also conceivable that the function of the brake booster that makes up the brake system may be impaired.

を高めることができる。As shown in FIGS. 1 and 2, the present invention provides a through hole 8 and a check valve 6a in the front part (with respect to the rotational direction) of the discharge port 4 in the same way as the suction port 1, through which air is drawn. By flowing in, oil is prevented from stagnation in the discharge port 4 portion, and noise and destruction of the vane 5 due to collision between the vane 5 and the stagnant oil are prevented. This also means that vacuum is supplied from the check pulp 6a in front of the discharge port 4 to other devices 12, and abnormalities in other devices 12 are directly applied to the abnormality tank 10.
The reliability of the control booster can be improved.

３が偏心して回転することによって、周知の様な空気の
吸入排出作用をなすものである。In the vacuum pump 9 shown in FIG. 1, a rotor 3 rotates eccentrically within a casing 2, thereby performing a well-known air suction and discharge operation.

とする。In this case, lubricating oil is generally supplied into the casing 2 and discharged from the discharge port 4 at the same time as the air, but when there is no load and no air is discharged, the inside of the casing 2 is at external pressure (atmospheric pressure).
On the other hand, since the vacuum is high, lubricating oil (oil) becomes difficult to be discharged and tends to stay near the discharge port 4.

By providing a through hole 8 and a second check valve 6a similar to the above, when there is no load, air can flow in from there (in other words, negative pressure can be supplied to the equipment 12 via the hose 7),
The lubricating oil that remains near the discharge port 4 is forcibly discharged from the discharge port 4 to prevent noise and damage to the vane 5 due to collision between the vane 5 and the remaining lubricant.
