The booster pump 100 includes a valve operation space having an air supply portion 112a and a drain portion 112b on the upper and lower sides of the main operation space 111 as disclosed in Korean Patent No. 10-0865908 A housing 110 having a fluid inlet 114a and a fluid outlet 114b having a fluid inlet 114a and a fluid outlet 114b; a compression piston 115 inserted into the fluid outlet 114; A lifting piston shaft 130 having a working piston 16 mounted on the main operating space 111 and a slide valve 120 mounted on the valve operating space 112; And a connecting pipe 140 for interconnecting the lower portion of the valve operating space 112 and the valve operating space 112.

The slide valve portion 120 includes a spring resilient portion 124 including a valve body 122 and disposed between the inside of the valve body 122 and the lifting piston shaft 130, And an operation pipe 125 provided between the lift piston shaft 130 and the operation piston 116.

The spring resilient portion 124 has a protruding protrusion 124a and a stop ring 124b respectively provided around the lower and upper portions of the inner hole of the valve element 122 and a protruding protrusion 124a and a stop ring 124b provided between the protruding protrusion 124a and the stop ring 124b The upper and lower operating plates 124d and 124e provided upward and downward through the compression spring 124c and the operating lifting and lowering arm 130b inserted into the lifting piston shaft 130 between the upper and lower operating plates 124d and 124e Body 124f.

In order to maximize the pumping efficiency and durability life of the slide valve, the present invention minimizes the number of parts for generating a snap to guide the slide valve and minimizes the machining work, And a lifting device (1) for guiding the lifting and lowering of the slide valve that is lifted and lowered in the valve operating space as the compression piston and the operating piston are lifted in the main working space formed inside the housing of the booster pump.

The lift device according to the present invention is configured to move the valve body 122 which is a steel material provided on the slide valve portion 120 raised and lowered in the valve operation space 112 to the valve operating space 112 , And magnetic force means (10) provided below the magnetic force means (10).

In other words, the present invention can be applied not only to direct contact with the valve body of the slide valve portion, which is the mechanical contact type of the present applicant's Registration No. 10-0865908, but also to the magnetic force by the magnetic force means So that the lift can be accomplished.

Therefore, the present invention has a condition that the valve body of the slide valve portion does not come into direct contact with the valve body as in the above-described patent having the guide locking portion, so that wear and the like do not occur, thereby not only improving the durability life but also the noise caused thereby.

Accordingly, it is possible to smoothly move up and down the slide valve unit, thereby improving the pumping efficiency.

Furthermore, the present invention has the advantage that the number of components can be minimized and the efficiency of the assembling work can be enhanced, since the present invention can be implemented without complicated structure for providing the guide locking portion as in the registered patent or without complicated processing.

The magnetic force means 10 includes a first magnet 12 provided on the upper stopper 112A of the valve operating space 112 at a position corresponding to the upper surface of the valve body 122 of the slide valve portion 120, And a second magnet 14 provided on a lower stopper 112B of the valve operating space 112 at a position corresponding to a bottom surface of the valve body 122 of the slide valve body 120. [ At this time, the first magnet 12 is embedded so as not to protrude from the bottom surface of the upper stopper 112A so as not to interfere with the upper surface of the valve body 122, and the second magnet 14 is also embedded in the bottom surface of the valve body 122 So as not to protrude from the upper surface of the lower stopper 112B.

On the other hand, the valve body of the slide valve unit according to the present invention is advantageous in that there is no need to make contact with the guiding locking portion as in the registered patent, that is, there is no need to process the concave-convex grooves and projections on the side surface.

In addition, it is possible to omit a complicated structure for constituting the guiding locking portion, which is a registered patent, and in particular, there is no need for various processes for installing the guiding locking portion. Therefore, the elevating apparatus of the present invention can be realized with a minimum number of parts as well as an advantage of improving the mechanical efficiency and durability without friction parts such as the registered patent.

The operation of the present invention will now be described with reference to FIGS. 3A through 3D.

When the air is supplied to the valve operating space 112 by the air supply unit 112, the introduced air flows into the upper portion of the main working space 111. As the operating piston 116 is lowered, To the compression position (see Figure 3A)

The upper surface of the valve body 122 constituting the slide valve portion 120 is lowered while being separated from the first magnet 12 formed on the upper stopper 112A and the lower surface of the valve body 122 is connected to the lower stopper 112B by the magnetic force of the second magnet 14 (see Fig. 3B)

The air flowing into the air supply portion 112a flows into the connection pipe 140 through the space formed around the valve body 112 and then flows into the lower portion of the main operation space 111, 116 are lifted up again to the top (see Fig. 3C).

As the operating piston 116 is raised, the compression piston 115 is moved to the suction position and the valve body 112 for driving the slide valve portion 120 is lifted. At this time, the lower stopper 112B The bottom surface of the valve body 112 attached to the second magnet 14 is lifted and attached by the first magnet 12 of the upper stopper 112A while being separated.

The operation of discharging the air from the air drain portion 112b formed in the valve operation space 112 proceeds in the process of lifting and lowering the actuating piston 116 and the valve body 120 as described above.

Accordingly, the fluid supplied through the fluid inlet 114a is compressed and discharged continuously to the fluid outlet 114b while the above operation is repeatedly performed.

On the other hand, an operation of instantaneously lifting and lowering the valve body 122 through the spring action of the spring resilient portion 124 constituting the slide valve portion 120 is similar to that described in Patent No. 10-0865908 And a detailed description thereof will be omitted.

Thus, according to the present invention, it is possible to maximize the efficiency and durability by minimizing the friction loss by making the lift valve for guiding the valve body lifting and lowering of the slide valve portion generate the instantaneous snap due to the magnetic force, I have.

In addition, the structure also has a condition that can be implemented with a simple structure with a minimum number of components as a mechanical element is omitted. This maximizes machining efficiency as well as efficiency and durability of the assembly.
