    on the plate 15 is fixed in the axial direction l screw 24.
    In the embodiment of a turkushnev machine there is a housing 25, a drive shaft 26 with a supporting element in the form of an eccentric 27 and an intermediate part 28 installed on it, two opposed cylinders 29 with pistons 30 installed with the ability to interact with the intermediate part 28 of the supporting element and connected between by means of a U-shaped bracket 31, covering the supporting element 27 and the intermediate piece 28, and having at the ends a clamp terminal 32 with a screw 33 for rigid connection with a corresponding piston 30. The terminal clamp 32 includes 34 with a hole 35 to accommodate the end of the piston 30. The tide 34 is opened on one side by a groove 36, made symmetrically to a horizontal plane passing through the axis of the hole 35, while in the upper part of the tide 34 there is a hole 37 for passage of the screw 33, and in the bottom - a threaded hole 38 for the installation of the screw 33 (Fig.8sh.
    Each piston 30 is provided with a support shoe in the form of a plate 39 with a shank 40, is cylindrical along the entire length and has a blind hole 41 at the end facing the eccentric 27 to accommodate the shank 40 of the plate 39 (Fig. 7),
    The bracket 31 in the area between the terminal clips is provided with two interconnected longitudinal parallel end walls 42 installed with the possibility of setting at least part of the intermediate part 28, while the bracket 31 can be equipped with longitudinal stiffening ribs 43 (Fig. 14),
    The machine can be equipped with an additional bracket 44, an opposed main bracket 31, both brackets 31 and 44 are provided with side walls 45, and terminal clips 32 are provided in the side walls 45 for connecting the main 31 and the additional 44 brackets to each other and with the piston 30 (FIG. 12),
    The intermediate piece may be made in the form of a slider 46 having flat bearing surfaces 47 for interacting with the respective plates 39 of the supporting shoes of the pistons 30 (Fig. 13). In this case, the Plas515
    The tine 39 of the support shoe is provided with side projections 48, and the bracket 31 is provided in pairs 49, while the projections 48 of the plate 39 are located in the slots 49 of the bracket 31 (FIG. 14) .v
    The piston 30 can be fixed in the bracket 31 by means of a collet clamp (Fig. 15 and 16). In this case, in tide 34, an internal tapered thread is made into which a collet 50 is screwed around the piston 30. The 50 has an external tapered thread 51 and a hexagon 52.
    The piston 30 can be fixed in the bracket 31 and in another way (Lig. 1). In this case, in the tide 34 of the bracket 31, a step boring 53 is performed, in which the clamping element 54, which encompasses the piston 30, is stirred. The opposing element 54 is pressed in the axial direction by means of a flange 55 with a flange 56,
    Another option for mounting the pistons 30 in the bracket 31 is shown in FIG. 18, where bore 58 is mounted in the tide 34 of the caliper to accommodate the piston 30 and thread 59 is set for the set screw 60, which fixes the piston 30 in the bracket 31.
    A piston machine is assembled and operates as follows.
    In the piston machine (Figs. 1-6) with the lid 2 removed, the pistons 6 are inserted into cylinders 5, with the help of a terminal clamp 17 the support shoes 7 are fixed on the pistons x 6, the eccentric 10 and the support element 9 are mounted on the drive shaft 11 after which the pistons 6 are lowered in the cylinders 5 until their supporting shoes 7 come into contact with the supporting element 9, after which the gripper 12 is installed so that its protrusions 13 mate with the surface 14 of the supporting shoe 7. After these operations, the supporting element 9 and the gripper 12 on the eccentric 10 base plate 15 and screw 24, after installation cover 2 machine is ready for operation.
    In a piston machine (FIGS. 7-18), pistons 30 are introduced into cylinders 29 of housing 25 and connected to bracket 31, while plates 39 of supporting shoes of pistons 30 are in contact with intermediate piece 28 or 46.
    Piston machine (Fig. 1-6) works as follows.
    576
    When the drive shaft 11 is rotated, the pistons 6 in the cylinders 5 are driven by the eccentric 10 in a reciprocating motion to perform the suction and discharge strokes. At the same time, the supporting shoes 7 of the pistons 6 interact with a flat surface 19 with the supporting element 9 of the eccentric 10. When performing the suction stroke, the protrusions 13. of the grippers 12 interact with the surface 14 of the supporting shoe 7, thereby ensuring the forced air of the pistons 6 .
    Piston machine (Fig. 7-18) works as follows.
    When the drive shaft 26 rotates, the pistons 30, interconnected by the clip 31, are driven by the eccentric 27 in reciprocating motion in the cylinders 29 to perform the suction and discharge strokes. When performing an injection stroke in one of the cylinders 29 in the opposite cylinder 29, a suction stroke occurs and vice versa.
