Two radial boreholes 15, 16 grooves 25 that bridge the lower seal 27, and connected to these, downwards or upwards through the neck bearing 35 downwards into the casing tube Running oil grooves 17, 18 are for the oil exchange 5 36 and then back through the return pipe 19 between the memory 12 and the interior of the foot bearing slot 37 and the borehole 38. Return pipe 19 on the one hand and the inner bore. This not only displaces the old one 20 of the pipe holder 14 and the bore 13 of other oil in the jacket pipe 36 but also a thorough one provided on the side. The tube holder 14 takes the above flushing of the neck bearing 35 at the same time with a closed end of the tube 19 against the pressure ιο flushing of the oil sump39 in the foot bearing 23. Under the spring 21 slidably. The pipe holder 14 is pressure then forces the oil upwards and overflows pierced at the top, so that the tongue 21 on the bores 22, 16 and the groove 18 in the memory taking inner bore 20 with the memory 12 in 12, until the one there a connection stands. The tube 19 has a radially closed, now compressed air to the oil pressure Outlet hole 22 at the top and is at the bottom 15 maintains balance and the oil flow comes to a standstill Ren end towards the spindle foot bearing 23 open. comes. The volume of memory in the handle and the The path of the return pipe 19 in the distributor 10 is the inner bore 20 in which the spring 21 is housed limited by an attached outer ring 24, is selected so that not only all waste oil, the one at the lower limit of the bore 13 but also the flushing oil that has flowed in, which is about on the side and on the tube holder 14 on the other hand in stop 20 a third to half of the volume of used oil gets by. The tube 19 also has a feature that finds space. Also the displacement volume number of channels formed as grooves 25, which are used to ver the pipe 19 is chosen so that the oil level in the Tical oil passage serve as soon as the tube 19 in the jacket tube 36 after retraction of the tube 19 one upper position (operating position) according to FIG. 1 corresponds to a certain required amount. To is pushed. Of the two, the return pipe 19 25 withdrawal of the lubricating head 4 from the spindle surrounding Seals 26, 27, the lower part of the manifold moves the pipe 19 under action 10 by two pressed-in bushings 28, 29 held the spring 21 back in the lower rest position are, the lower 27 is in the operating position (Fig. 2), whereby the drainage of the old and flushing oil said grooves 25 bridged. The cans from the memory 12 of the hollow handle 11 on the have enough play with respect to the pipe, 30 hole 15 and the groove 17 is released. the so that an oil passage along the circumference of the fresh oil container 1 must be designed so that between-pipe 19 can be done. Between the mentioned see the maximum and the minimum oil level Seals 26, 27 opens the fresh oil inlet channel the pressure no more than z. B. from 7 to 3 atü from -30. Sitting in an enlarged lower bore 31 sinks. At the lower limit of the allowable pressure still two under spring tension sealing 35 at z.

The resulting differences can however be accepted. The device now works as follows: That can also be taken in, since it is within the too-non-operational state Fresh oil under pressure 40 permissible tolerances of the required amount of flushing oil flows after moving the return pipe 19 in move.

Spindle lubricator for spinning and twisting must be lowered. spindles, with a line for the supply and 5 The invention is based on the object of providing a discharge of oil-containing lubricating head to the spindle lubricating device for spinning and twisting spindles placed on the spindle bearing housing, of the type mentioned above, with which a and in the non-operational position, the oil exchange can be carried out largely automatically and in a displaceable manner in the spindle bearing housing in a particularly short time.
To achieve this object, the invention provides that the return pipe (19) provides that the return pipe has at least one outlet channel which is open in at least one operating position and closed in non-operating and non-operating positions and closed in the non-operating and non-operating positions Exit from laßkanal (22) for the exit of used and flushing oil used and flushing oil in a lubricating head located in a lubricating head (4, 11/10) located 15 borrowed memory and that between the memory (12) and that between the Return pipe and return pipe guide parts Control return pipe (19) and return pipe guide channels are provided, which in the operating position share one (14, 27) control channels (25, 22, 16, 18; 15, fresh oil passage to the spindle bearing housing and in 17) are, which in the operating position a non-operating position with the closure of this fresh-fresh oil passage to the spindle bearing the housing (34) 20 oil passage open a storage drain,
