[Embodiment of the invention]

 Hereinafter, an example showing an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the hermetic compression pump of this embodiment mainly includes a pressure cylinder 1, a hermetic pusher 2, and a fixed base 3.

The pressure cylinder body 11 has a first flange 12, a fluid chamber 13, a fluid inlet 14, and a fluid outlet 15. The first flange 12 has at least one groove 121 and at least two through holes 122.

The fluid chamber 13 is formed inside the pressure cylinder main body 11. The fluid chamber 13 is divided into a second space 132 and a first space 131. The second space 132 is provided with a fluid inlet 14 below and a fluid outlet 15 at a side end. The shape of the second space 132 is a truncated cone shape toward the fluid outlet 15.

In the fluid inlet 14, an elastic element 142, a one-way valve 141, and a pipe joint 143 are sequentially arranged. Fluid is introduced through a conduit connected to fitting 143 and enters fluid chamber 13 via one-way valve 141. As shown in FIG. 5, the one-way valve 141 compresses the elastic element 142 when the fluid enters. When the fluid flows in through the fluid inlet 14, the fluid does not flow back through the fitting 143.

The fluid outlet 15 includes a one-way valve 151, an elastic element 152, and a pipe joint 153 arranged in this order. The fitting 153 is connected to a conduit, and the fluid is transported to the set position via the conduit. As shown in FIG. 6, when the fluid flows out, the one-way valve 151 compresses the elastic element 152, and the fluid flows out through the fluid outlet. Since the one-way valve 151 functions as a check valve, when the fluid flows out, the fluid does not flow backward from the outside.

As shown in FIGS. 1 to 4, the hermetic pusher 2 is provided with a push element 21, a support shaft 22, an active shaft 23, and a support element 24. The push element 21 is provided with a ring cover 211, a deformable part 212, and a pillar part 213.

The ring cover 211 is tightly sandwiched between the first flange 12 of the pressure cylinder 1 and the second flange 32 of the fixed base 3. A convex ring 2111 is fitted in the groove 121 of the first flange 12. Therefore, the pressure cylinder 1 and the hermetic pusher 2 are in close contact with each other, and a leakproof effect is obtained. The ring cover 211 is provided with a plurality of through holes 2112, and the screw stopper 4 passes through the through hole 2112.

The deformation portion 212 is made of rubber or another flexible material having bending resistance. The deforming portion 212 is integrated between the ring cover 211 and the column portion 213. When the deforming portion 212 is not deformed, its shape is a bowl shape, and a concave portion 214 is formed inside. The shape of the deformable portion 212 is substantially the same as the shape of the first space 131 of the fluid chamber 13, and the deformable portion 212 can be fitted into the first space 131.

The column portion 213 is provided on the pressure cylinder 1 side of the deformation portion 212 so as to protrude in a truncated cone shape toward the fluid outlet 15. The column 213 can be fitted into the second space 132. The support shaft 22 is fixed to the pillar 213 at one end, and the other end of the support shaft 22 and the active shaft 23 are connected by screws. As a result, the strength of the column 213 increases. The screw portion 221 of the support shaft 22 is screwed into a screw hole 231 of the active shaft 23.

The active shaft 23 has a support shaft 22 screwed to one end, and a connecting element 56 of the driving device 5 to the other end, as shown in FIGS. 5 and 6. . The active shaft 23 reciprocates in the bearing 33 of the fixed base 3 in the longitudinal direction.

The support element 24 is fixed to the active shaft 23. The shape of the supporting element 24 is substantially the same as the internal shape of the deformed portion of the pressing element 21 when the deformed portion 212 is not deformed.

As shown in FIG. 1 to FIG. 4, the fixed pedestal 3 has an active chamber 311 formed in a ventilation main body 31. When assembling, the convex ring 2111 is fitted into the groove 121, the screw plug 4 is passed through the through holes 122 and 2112, and then screwed into the screw hole 321 of the second flange 32. Therefore, the fluid chamber 13 of the pressure cylinder 1 and the active chamber 311 of the fixed base 3 are separated by the pushing element 21, and the fluid chamber 13 is in a closed state.

The bearing 33 is provided at the center of the ventilation body 31 on the side opposite to the pressure cylinder so as to protrude in the longitudinal direction of the active shaft 23. The active shaft 23 penetrates the bearing 33 and is movable in the longitudinal direction.

The bottom plate 34 is used to fix the bottom plate at a predetermined position. As shown in FIGS. 5 and 6, the driving device 5 is provided with a motor 51, a driving wheel 52, a belt 53, a driven wheel 54, a curved shaft 55, and a connecting element 56.

The active shaft 23 fixed to the drive device 5 can reciprocate in the longitudinal direction. As shown in FIG. 5, when the active shaft 23 is moved by being pulled by the curved shaft 55, the support shaft 22 and the support element 24 are interlocked and move by pulling the column 213 and the deformable portion 212 of the push element 21. At this time, the deformable portion 212 is deformed, and at the same time, a suction force is generated.

As shown in FIG. 6, when the active shaft 23 is pushed back by the curved shaft 55, the support shaft 22 and the support element 24 push back the column portion 213 and the deformation portion 212, and the fluid inside the fluid chamber 13 is compressed, The fluid is pushed out from the fluid outlet 15. When the active shaft 23 is pushed back to the compression cylinder side, the column 213 fits into the first space 131 and completely pushes out the fluid in the fluid chamber 13 to the outside. Therefore, the inflow is clearly smaller than the outflow, and high compression efficiency is obtained.

Further, in the compression system of the present embodiment, friction does not occur on the wall surface of the fluid chamber 13, so that friction heat does not occur even without using lubricating oil. In addition, there is no immediate wear of parts.
