Description

The invention relates to a rotary scroll compressor pump with liquid pistons formed periodically, alternately with the compressed gas in a spiral liquid.

In the proposed compressor pump, the coil is rotatable both around its own axis and around an axis located in a plane perpendicular to the plane of the helix. A conical disk connected to the body of the spiral and a stationary conical wheel are used to perform the friction transmission between the axes of rotation of the helix.

On oyig. 1 shows a pump-compressor in a vertical longitudinal section on the axis of the main shaft; in fig. 2 - the same, in a horizontal longitudinal section on the axis of the main shaft; in fig. 3 - engine in cross section; pas figs. 4 shows a compressor pump in section Io A-.4 in FIG. 2

Spirally bent sheets / are fixed on the l, suits 2 (Fig. 1, 2, 3), mounted on the hollow shaft 5. The ends of this shaft are located in the frame 4 supported by two hollow shafts 5 and 6. To the disks 2 are attached conical rings 7 ( Fig. 2), serving for friction coupling with fixed conical wheels 8.

The rotation of the frame 4 of the compressor pump is transmitted directly from the electric motor through the shaft 9 and the hollow shaft 5. When the frame 4 rotates and the spiral supported by this frame, the conical ring 7 attached to the housing rolls along the stationary conical wheel 8 and, pressing to it with some force, causes the helix to rotate around its own axis. The moment of gyroscopic forces arising at the same time causes some helixing of the axis of the helix, which provides the necessary friction for the transfer of the contact of the two cones along the generators, while on opposite sides of the cones there is a small gap. .

The rotation of the helix around the 0–0 axis is carried out many times faster than around its own axis O – 0, as a result of which centrifugal forces arise within the helix directed opposite to the axis O – O. The center of the helix enters space 10 through pipes U, 12 (Fig. 2), J3, 14 (Fig. 1) and / 5 (Figs. 1, 3), which under the action of the centrifugal force develops around the periphery relative to the axis oo. Outside air also enters that space. At the same time the rotation of the helix 1 around its own axis Oi-Oi, the liquid will move relative to the helix, the passage partially to the aisles 29, where the air also flows. Transfusing under the action of centrifugal force along the spiral paths, the fluid forms liquid pistons 30, which drive ahead of themselves in the aisles of the spiral and captured air and always form liquid closures preventing air from returning. Due to the reduction in the cross section of the spiral aisles, the liquid pistons at each turn of the spiral cause the air to occupy smaller and smaller volumes and thus produce a stepwise compression of the air. Approach to the periphery, the compressed air and the liquid enter the exit chamber 31 (Fig. 2 and 3), from where the fluid comes through pipes 32, 16, 17 (Fig. 3), 18 (Fig. 1) and 19 (Fig. 1, 2 and 4) is fed to a non-movable outlet chimney 20 connected to the hollow shaft tube 19 with the gland seal 21; compressed air, which in the chamber 31 was located near its center due to its lower density as compared with a liquid, passes through pipes 22, 23, 24 (Fig. 3), 25 (Fig. 1) and 26 (Figs. 1, 2 and 4 ) to the fixed pipe 27 through the gland 2S.
