Abstract

The vane type pump/compressor for compensating the defect generated from the eccentricity, has the double roller type structure having a main rotating body with a vane and a subsidiary rotating body for helping the reciprocating of the vane contained in the main rotating body, mounted at the center of the housing. The vane type pump/compressor comprises a main rotating body(8) having inner reciprocating vane(10); subsidiary rotating body(9) contacted with the main rotating body and driven by the power transmission(3)(4) for supporting the separation of the suction/compression sections or the reciprocation of the vane(10); discharging path including the discharging groove(7) and the case-cover discharging hole(6).

The present invention relates to vane type pumps and compressors. More specifically, there is a main rotor with wings in the center of the housing composed of concentric circles with opposite sides, and a double roller type structure having a secondary rotor supporting the reciprocating motion of the vanes housed in the main rotor. It relates to a pump and a compressor.

Vane-type pumps and compressors with air technology are designed with an eccentric or elliptic structure inside the case.

This should sharpen the contact with the case at the outer edge of the wing or make it semicircular.

As a result, it became difficult to maintain airtightness and became vulnerable to abrasion of the wings and the case, thus making it difficult to manufacture a compressor having a high compression ratio.

The main purpose of the present invention is to compensate for the shortcomings caused by the eccentricity of the vane type pump compressor. To this end, a main rotor body inserted with a blade inserted in the center of the concentric housing has been overcome.

It will be described in detail according to the accompanying drawings of the present invention below.

1 is an exploded perspective view of main parts of a pump and a compressor of the present invention.

According to the drawing is divided into two threads in the same direction as the main shaft (1), the left chamber is a gear case (5) in which the main gear (3) and the driven gear (4) is built, and also has a lubricating oil storage function.

The right chamber is a compression chamber that plays a substantial pumping or compression role.

The structure of the compression chamber consists of a case (2) having opposing side walls and an inner circumferential surface of a concentric circle.

The main chamber case 2 and the main chamber case cover 17 are in airtight contact with the side surfaces of the main rotating body 8, the auxiliary rotating body 9, and the wing 10.

In the case 2 having an inner circumferential surface of the concentric circle, a circular recess 11 is installed in the upper portion, and the auxiliary rotating body 9 is hermetically inserted in the circular recess 11.

A suction hole 12 is also installed in front of the auxiliary rotating body on the basis of the rotation direction of the main rotating body.

The main rotating body 8 is installed in the inner center of the case 2.

The main rotor has a cylindrical shape in which the groove 13 is installed in the axial direction so as to be airtightly inserted so that the wing 10 can be actuated, and the discharge hole 14 is installed in front of the wing 10 to discharge the discharge valve 15 therein. ) Is built-in.

The blade 10 inserted into the main rotating body has a rectangular plate shape, and the outer end of the blade is composed of the same curvature as the inner circumferential surface of the case 2.

When the main rotor rotates, the blade 10 protrudes with centrifugal force, and the inner circumferential surface and the outer end of the case 2 are in airtight contact with each other. The reciprocating motion is re-projected with centrifugal force while leaving the contact surface of.

The auxiliary rotor 9 is circumferentially inserted into the circular recess 11 of the case to be hermetically rotated in airtight contact with the outer circumferential surface of the main rotor 8 and also serves as an intermediate blocking wall of the compression chamber.

The main rotating body 8 and the main gear 3 are arranged in the main shaft 1, and the auxiliary rotating body 9 and the driven gear 4 are built in the vertical axis 16.

The size ratio of the main gear 3 and the follower 4 is the same as the size ratio of the main rotor 8 and the subsidiary rotor 9 so that the main rotor 8 and the subsidiary rotor 9 are mutually slippery. Fold face tightly and rotate.

FIG. 2 is an assembly cross-sectional view of the pump and compressor of the present invention as seen from the line A-A of FIG.

3 is an exemplary view showing an operating state of the pump and the compressor of the present invention.

The fluid is sucked through the intake hole 12 at the rear of the blade 10 by the rotation of the main rotor 8 and at the same time pressurizes the fluid already sucked in front of the blade 10 to pass through the slit 18. 15 is pushed out and discharged to the outside through the discharge hole 14, the discharge groove 7 and the discharge hole 6.

At this time, the wing 10 is protruded from the groove 13 of the main rotating body 8 by centrifugal force and the outer end is moved in airtight contact with the inner surface of the case 2, and the main rotating body groove ( It is inserted into the core part of 13), crosses the contact surface with the auxiliary rotating body 9, and is protruded by centrifugal force repeatedly to perform repeated strokes.

The auxiliary rotating body 9 serves as a blocking wall for separating the suction part and the pressurizing part as the main body of the present invention, and supports the process of being inserted during the reciprocating motion of the wing 10 so that the main rotating body 8 can be installed at the center of the case. In charge of key dynamics.

This complements the eccentricity, which is a drawback of vane-type pumps and compressors in the known art.

Maintaining the inner surface contact portion of the wing 10 and the casing 2 constantly means that the wing surface can be widened by arbitrarily selecting and extending the thickness of the wing.

This ensures a tighter air tightness, which is a good advantage for high compression ratio compressors and pumps.

In addition, the wide and constant contact is a big advantage in the extension of durability.
