상기한 바와 같이 본 발명의 구성을 첨부한 도면에 의해 상세히 설명하면 다음과 같다. When described in detail by the accompanying drawings, the configuration of the present invention as described above are as follows.

도 1은 본 발명 유압 구동식 수압펌프의 구조를 나타내기 위한 분리 사시도이고, 도 2는 본 발명 유압 구동식 수압펌프의 구조를 나타내기 위한 결합 사시도이며, 도 3은 도 2의 A-A선 단면도를 도시한 것이다.1 is an exploded perspective view for showing the structure of the hydraulic pressure-type hydraulic pump of the present invention, Figure 2 is a combined perspective view for showing the structure of the hydraulic pressure-type hydraulic pump of the present invention, Figure 3 is a cross-sectional view taken along line AA of FIG. It is shown.

도 3을 참조하면, 상기 유압실(111)은 상기 오일출입구(111b) 또는 오일출입구(111a)를 통해서 유입 및 배출되는 오일의 유압에 따라서 상기 피스톤(120) 및 확경부(121)를 전후방향으로 이동시키는 역할을 수행하게 된다.Referring to FIG. 3, the hydraulic chamber 111 moves the piston 120 and the enlarged diameter portion 121 back and forth according to the oil pressure of the oil flowing in and out through the oil inlet 111b or the oil inlet 111a. It will play the role of moving to.

또한, 상기 통공(112)은 상기 가이드축(122)의 외경과 맞닿은 상태에서 상기 피스톤(120)을 전후방향으로 원활하게 이동할 수 있도록 유도하게 된다.In addition, the through hole 112 is guided to smoothly move the piston 120 in the front and rear directions in contact with the outer diameter of the guide shaft 122.

이를 위해서 상기 통공(112)과 가이드축(122)은 상기 피스톤(120)의 길이방향으로 형성됨은 당연할 것이다.For this purpose, the through hole 112 and the guide shaft 122 will be naturally formed in the longitudinal direction of the piston 120.

이때 상기 통공(112)의 내경에는 상기 가이드축(122)의 외경과 밀착되어 오일의 외부유출을 방지하기 위한 패킹부재(112a)가 형성된다.At this time, the inner diameter of the through hole 112 is in close contact with the outer diameter of the guide shaft 122 is formed with a packing member (112a) to prevent the outflow of oil.

본 발명에서 적용되고 있는 패킹부재는 기밀성을 확보하기 위한 수단으로, 구조 및 작용원리는 당업계에서 보편적으로 사용되는 공지의 기술이므로 상세한 서술은 생략하기로 한다. The packing member applied in the present invention is a means for securing airtightness, and the detailed description thereof will be omitted since the structure and the principle of action are well-known techniques commonly used in the art.

한편, 상기 축경부(113)는 상기 피스톤(120)의 외경에 맞닿은 상태에서 전후방향으로 유도함은 물론 상기 수압실(114)의 내부로 공급되는 물이 상기 유압실(111)의 내부로 혼입되는 현상을 방지하기 위한 역할을 수행하게 된다.On the other hand, the shaft diameter 113 is guided in the front and rear direction in contact with the outer diameter of the piston 120 as well as the water supplied into the hydraulic chamber 114 is mixed into the hydraulic chamber 111. It will play a role to prevent the phenomenon.

이를 위해서 상기 축경부(113)의 내경에는 상기 피스톤(120)의 외경과 밀착되어 기밀성을 확보하기 위한 패킹부재(113a)가 형성된다.To this end, the inner diameter of the shaft diameter portion 113 is in close contact with the outer diameter of the piston 120 is formed with a packing member 113a for ensuring airtightness.

상기 수압실(114)은 상기 피스톤(120)의 후진과정에서 발생하는 흡입력으로 상기 물유입구(115)를 통해서 물을 유입시켜 저장하게 되고, 반대로 상기 피스톤(120)이 전진하게 되면 상기 수압실(114)의 내부에 저장된 물을 상기 물배출구(116)를 통해서 일정한 압력으로 배출시키게 된다.The pressure chamber 114 is introduced into the water through the water inlet 115 as a suction force generated in the backward process of the piston 120, and stored, on the contrary, when the piston 120 is advanced, the pressure chamber ( The water stored inside 114 is discharged at a constant pressure through the water outlet 116.

본 발명에서 상기 물유입구(115)는 상기 수압실(114)의 상부에서 내부로 관 통되도록 형성하고, 상기 물배출구(116)는 상기 수압실(114)의 하부에서 내부로 관통되도록 형성함이 바람직한데, 이는 상기 피스톤(120)의 후진으로 발생하는 흡입력으로 인해서 상기 볼(115a)은 하강하면서 상기 물유입구(115)를 개방하여 물을 유입하게 되고, 반대로 상기 볼(116a)은 상승하면서 상기 물배출구(116)를 밀폐하기 위함이다.In the present invention, the water inlet 115 is formed so as to pass through from the upper portion of the pressure chamber 114, the water outlet 116 is formed so as to penetrate from the lower portion of the pressure chamber 114 to the inside Preferably, this is due to the suction force generated by the reverse of the piston 120, the ball 115a is lowered while opening the water inlet 115 to enter the water, on the contrary, the ball 116a is raised as the This is to seal the water outlet 116.

특히 상기 물유입구(115)와 물배출구(116)는 상기 볼(115a,116a)의 지름보다 더 크게 형성함으로써 이동공간을 확보한 후 상부방향으로 갈수록 지름이 점차 줄어드는 원추형상을 갖도록 형성함이 바람직한데, 이는 상기 볼(115a,116a)이 상승하면서 상기 물유입구(115) 및 물배출구(116)의 내경에 맞닿도록 유도하여 밀폐시키기 위함이다.In particular, the water inlet 115 and the water outlet 116 is formed larger than the diameter of the ball (115a, 116a) to secure a moving space and preferably have a conical shape that gradually decreases in diameter toward the upper direction. However, this is to induce and seal the ball (115a, 116a) to be in contact with the inner diameter of the water inlet 115 and the water outlet (116) while rising.

한편, 상기 스프링(115b,116b)은 탄성력에 의해서 상기 볼(115a,116a)을 상승시켜 상기 물유입구(115)와 물배출구(116)를 밀폐시키는 역할을 수행하게 된다.On the other hand, the spring (115b, 116b) serves to seal the water inlet 115 and the water outlet 116 by raising the ball (115a, 116a) by the elastic force.

즉, 평소에는 상기 스프링(115b,116b)의 탄성력으로 상기 볼(115a,116a)을 상승시켜 상기 유입구(115)와 물배출구(116)의 내경을 밀폐시키게 되고, 상기 피스톤(120)이 후진하게 되면 흡입력과 함께 상기 물유입구(115)의 내부에 형성된 볼(115a)이 하강하면서 물이 상기 수압실(114)의 내부로 유입된다.That is, normally, the balls 115a and 116a are raised by the elastic force of the springs 115b and 116b to seal the inner diameters of the inlet 115 and the water outlet 116, and the piston 120 moves backward. When the ball 115a formed in the water inlet 115 is lowered together with the suction force, water is introduced into the pressure chamber 114.

이때 상기 스프링(115b,116b)은 탄성력을 유발하는 공지의 압축스프링을 사용함이 바람직하다.At this time, it is preferable that the springs 115b and 116b use a known compression spring that induces an elastic force.

상기 피스톤(120)은 상기 오일출입구(111b) 및 오일출입구(111a)를 통해서 유입 및 배출되는 오일의 유압에 따라서 전후방향으로 이동하면서 상기 수압 실(114)의 내부에 저장되는 물을 입정한 압력으로 배출하게 된다.The piston 120 moves in the front-rear direction according to the oil pressure of the oil flowing in and out through the oil inlet 111b and the oil inlet 111a, and pressurizes the water stored in the hydraulic chamber 114. Will be discharged.

특히 상기 확경부(121)의 외경에는 상기 유압실(111)의 내경과 밀착되어 작동되는 과정에서 발생하는 오일의 외부유출을 방지하기 위한 패킹부재(121a)가 형성된다.In particular, the outer diameter of the enlarged diameter portion 121 is formed with a packing member 121a for preventing the outflow of oil generated in the process of being in close contact with the inner diameter of the hydraulic chamber 111.

아울러 상기 가이드축(122)의 일단에는 돌기(122a)를 구비하고 상기 가이드축(122)의 일측에는 길이방향으로 일정간격 이격되도록 위치감지센서(122b)를 형성하는데, 이는 상기 피스톤(120)의 전후진 위치를 확인하기 위함이다.In addition, one end of the guide shaft 122 is provided with a protrusion 122a and on one side of the guide shaft 122 to form a position sensor 122b to be spaced apart at regular intervals in the longitudinal direction, which is the This is to check the forward and backward position.

이하 상기와 같은 구성을 갖는 본 발명 유압 구동식 수압펌프(100)의 작동상태를 첨부한 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the operation state of the present invention hydraulically driven hydraulic pump 100 having the configuration as described above in detail with the accompanying drawings as follows.

도 4 또는 도 5는 본 발명 유압 구동식 수압펌프의 작동과정을 나타내기 위한 순서도를 도시한 것이다.4 or 5 shows a flow chart for showing the operation of the hydraulic-driven hydraulic pump of the present invention.

도 4를 참조하면, 상기 오일출입구(111b)를 통해서 유입되는 오일에 의해서 상기 피스톤(120)이 후진하면서 흡입력이 발생하게 되는데, 이때 상기 볼(115a)은 하강하면서 상기 물유입구(115)를 개방하게 되고, 반대로 상기 볼(116a)은 상승하면서 상기 물배출구(116)를 밀폐시키게 되므로, 이로 인해 상기 수압실(114)의 내부로 물을 저장할 수 있게 된다.Referring to FIG. 4, the suction force is generated while the piston 120 moves backward by the oil flowing through the oil inlet 111b. At this time, the ball 115a is lowered and the water inlet 115 is opened. On the contrary, since the ball 116a rises to seal the water outlet 116, the water 116a can store water into the pressure chamber 114.

도 5를 참조하면, 상기 오일출입구(111a)를 통해서 오일이 유입되면서 발생하는 유압에 의해서 상기 피스톤(120)을 전진하게 되는데, 이때 상기 볼(115a)은 상승하면서 상기 물유입구(115)를 밀폐하게 되고, 반대로 상기 볼(116a)이 하강하 면서 상기 물배출구(116)를 개방시키게 되므로, 이로 인해 상기 수압실(114)에 저장된 물을 배출시킬 수 있게 된다.Referring to FIG. 5, the piston 120 is advanced by hydraulic pressure generated while oil is introduced through the oil inlet 111a. At this time, the ball 115a is raised to seal the water inlet 115. On the contrary, since the water outlet 116 is opened while the ball 116a is lowered, the water stored in the pressure chamber 114 can be discharged.

따라서 상기 피스톤(120)의 전후진 과정에서 따라서 상기 수압실(114)의 내부에 저장된 물을 일정한 압력으로 배출시킬 수 있게 된다.Therefore, the water stored in the hydraulic chamber 114 may be discharged at a constant pressure in the forward and backward process of the piston 120.
