Description

The invention relates to a Re \ >> \ .ΊΥιΐΠϋϋϋ! door ^ pparaluren for treatment /.ellMolihiiHigi η MaIeials, like Holzschniizel oil.ilgl., to which a plural is connected by stations and one of the plummets is axially tied through a rotor through a multiple Generate the rotor-dependent force in such a way that the end walls are pressed evenly against the roller blind are.

In this way, the ones from the tie rods are now exercised power each for see so controllable, dal. ' even at very different pressures in the areas of the revolver supply between Sliinwander and rotor is adjustable to a uniform sealing gap. Thus, there will be uneven wear counteracted.

Tie rods lie evenly around the perimeter of the following:

End walls distributed and outside the rotor. The io If in one of the spaces 11 of the rotor 1 a lower, threaded end of the tie rod 4 is under pressure in comparison with the other spaces 11 by means of nuts 5 in the flange 36, the end walls 2, 3 graze an untrusted end wall 3 clamped. The tie rod 4 goes under pressure which tends to lift freely through a bore in the flange 35 of the end walls from the ends of the rotor I within the feed end wall 2, and to lift its upper 15 of the areas which is below the high end a piston 45 in a cylinder 46 pressurized space 11 are adjacent. By mistake. The cylinder 46 rests with its lower indicates that the high pressure area at the end next to the flange 35 and is conveniently connected to the tie rod or tie rods 4 located upwards. The piston 46 is being pulled while the rod 100 pulls the piston downwards in the exemplary embodiment with a guide sleeve in the valve housing 54. As a result 47, which is screwed onto the tie rod 4, the piston part 56 is brought to face one another. The position of the piston on the pull rod is to move the valve housing 54 downwards and is determined by a lock nut 48 which is screwed onto the extension 58 and thus also the return line 71 and on which the pull rod to the sump 72 is locked. On the other hand, the upper wall of the cylinder 46 is increasingly exposed more and more freely. This has existing guide sleeve 47 rests. On both sides of the column the result that the bens 45 conveyed by the pump 74 are pressurized medium chambers 49 and 50 respectively. The pressure medium chamber 50 communicates via a device 94, 70 and the extension 59 on the central part line 51 with a pressure-controlling device 57 of the piston past into the line 51 and into the device 52, and the pressure medium chamber 30, chamber 58 is conveyed .
