    Extruder Seal of the Invention An extruder machine for processing of plastic materials, rubber or polymers in which a stationary casing is provided with a generally tubular bore having an inlet opening near one end thereof, and a discharge opening at the other end thereof. A generally cylindrical rotor is rotatably mounted in the bore of the casing. The casing is comprised of a pair of generally coaxially aligned spaced apart cylindrical members, having a length substantially longer than their diameters. A heating or cooling fluid is passed in the spacing between the cylindrical members in a heat transfer relationship. Each pair of cylindrical members is provided with expansion/contraction joints to permit longitudinal expansion or contraction of the components with respect to one another. An annular flexible bellows seal is biasedly disposed within the spacing between the outer cylinder and the inner cylinder in a fluid tight relationship between the two to prevent leakage of cooling or heating fluid therefrom during periods of extruder operation.

    completely in the form of an outer casing with a face ring plate and a casing with a flange installed inside the casing with a flange xbraxing with the inner surface of the casing a channel for heat transfer fluid, and a sealing element placed on one 1 5 5 nce of the cylinder, the sealing element is made in the form of a ring covering the casing bellows, one end of which is attached to the flange of the casing, and the other is rigidly connected to the annular plate of the outer casing, and the channel for the heat transfer fluid is connected to the annular channel between the brim the inner surface of the bellows and the inner surface of the outer casing. In addition, the annular casing plate and the end of the casing are mounted to move relative to each other. The syringe machine is provided with an annular gasket rigidly connected to the annular plate and provided with an annular chamber and channels for submerging and discharging coolant. Figure 1 shows the syringe machine, oats view; figure 2 - node I in Fig in an enlarged scale. The syringe machine comprises a housing 1 made in the form of a series of cylinders including each outer casing 2 with an end ring plate 3 made integral with the casing 2, and a rotor 6 mounted along the casing 2 coaxially with the flange 5-8 of the cylindrical casing opening having a spiral cut 7-9 on the end suit. The rotor 6 is connected by a gearbox 10 to a rotational drive (not shown). A feed hole is used for the material supply. Lls and for unloading is a discharge hole 12 located at the end of the housing 1 in the syringe head 13, which unloads the material into the receiver 1. Sealing the element placed at one end of each cylinder is made in the form of an annular force covering the casing () it is 15, one end of each is fixed, for example, to the flange 5 of the casing 4, and the other end is rigidly connected to the annular plate 3 of the outer ozduha 2 through the cover 16, which is bolted to the annular plate 3. At the point of contact of the cover 16 with the annular plate 3, a sealing gasket 17 is installed. The casing is mounted to form between the outer surface and the inner surface of the casing 2 a channel 18 for the heat transfer fluid communicated with annular channel 19 between the outer surface of the bellows 15 and the inner surface of the casing 2, the holes a. A crank 16, connected to the annular plate 3 of the casing 2, is slidably seated on the outer surface of the casing 4 so that it can be moved, and the casing has a protrusion 20 placed in a groove 21 at the end of the cover 16 adjacent to the casing. A cap gasket 22 is formed with a cap 16 and an annular plate 3, bolted to an annular chamber 23 and channels 2 and 25 for supplying and discharging coolant. The outer surface of the skin 4 has spiral grooves 2b. For supplying heat transfer fluid, the nozzles 27 are designed. The syringe is operating as follows. The material is fed into the loading opening 1 and further while rotating the rotor 6 is stirred, homogenized and due to cutting 7-9 of the rotor 6 moves to the discharge opening 12 of the head 13. The material may be a resin, polymer or plastic-like substance that requires cooling in the flesh to or heating to 353С. Heating or cooling of the material is provided by supplying the heat transfer fluid to the channel 18 and the annular channel 19, each of which can be cold water, heated water, steam or other medium with the desired properties. - The sealing element in the form of a bellows 15 prevents this from extending compressing the leakage of heat transfer fluid into the gaps between the syringe elements undergoing various temperature expansions. The cooling fluid supplied to the annular gasket 22 provides cooling and cooling. freezing a polymer or other material that may leak from the syringe during processing, the present invention, by providing a sealing element in the form of a bellows, provides reliable sealing, prevents possible leakage of heat transfer fluid during
    expansion of the syringe elements due to the temperature difference, increasing the performance of the syringe machine and the quality of material processing.
