IPC: F16J15/44
Filed: 1980-06-25
Abstract: PURPOSE: To prevent leakage of the fluid from a shaft sealing device of sliced sleeve type likely to arise when the shaft in this sleeve rotates at a low speed or remains at a standstill by supporting at least one of those slices, provided with a groove femalethreaded, in such a way that it can rotate freely along the circumferential direction.  
     CONSTITUTION: When the number of revolutions of the shaft 1, N, drops to attain the preset value N 0 , a comparator 17 gives a motor drive signal to a motor 15,  which will actuate a sleeve 3b into rotation with the aid of a gear 14 and a sector  gear 12. This rotation of sleeve 3b is transmitted to another sleeve 3d through a pin  shaft 7, and the sleeve 3d turns for the same angle as the sleeve 3b. By this rotation  of sleeves 3b, 3d, the groove part 4b of screw groove 4 provided in the inside surface of each sleeve 3aW3d is blocked by the top 4a. Consequently, the fluid can be  prevented from leakage through following the screw groove 4.
