As an example of the compressor, as shown in FIG. 1, a sealed container 1 having a predetermined internal space, a frame 10 mounted inside the sealed container 1, and a frame 10 mounted on the frame 10. And a compressor mechanism for generating a driving force and a compressor mechanism for sucking, compressing, and discharging the gas by receiving the driving force of the power mechanism. And the bottom surface of the sealed container (1) is filled with oil (O), the frame 10 is provided with an oil feeder (Oil Feeder) for supplying the oil to the electric mechanism and the compression mechanism.

상기 오일을 공급하는 종래 오일공급장치의 일예로 소정의 길이를 가지며 내부에 관통구멍(21)이 형성되어 상기 압축기구부 및 전동기구부와 연통되는 오일유로(F)와 연통되도록 프레임(10)의 하부에 축방향으로 장착되는 오일실린더(20)와, 소정의 길이를 가지며 내부에 오일이 유동되는 오일통로(31)가 형성되어 상기 오일실린더(20)의 관통구멍(21)에 움직임 가능하게 삽입됨과 더불어 오일실린더(20)의 내부를 흡입공간(a)과 토출공간(b)으로 구획하는 오일피스톤(30)과, 상기 흡입공간(a)과 토출공간(b)에 각각 삽입되어 오일피스톤(30)의 양단을 탄력 지지하는 흡입측 오일스프링(40) 및 토출측 오일스프링(50)을 포함하여 구성되어 있다.An example of a conventional oil supply device for supplying the oil has a predetermined length and a through hole 21 formed therein so that the lower portion of the frame 10 communicates with the oil flow path F, which communicates with the compression mechanism part and the electric mechanism part. And an oil cylinder 20 mounted in the axial direction, and an oil passage 31 having a predetermined length and flowing oil therein to be movably inserted into the through hole 21 of the oil cylinder 20. In addition, the oil piston 20 partitions the inside of the oil cylinder 20 into the suction space a and the discharge space b, and the oil piston 30 is inserted into the suction space a and the discharge space b, respectively. It comprises a suction side oil spring 40 and the discharge side oil spring (50) for elastically supporting both ends.

그리고 상기 토출측 오일스프링(50)과 이에 접촉되는 오일피스톤(30)의 일측면사이에 오일피스톤(30)의 왕복운동에 의한 유체의 흐름에 의해 오일피스톤(30)의 오일통로(31)를 개폐하는 오일흡입밸브(60)가 삽입되고, 상기 토출공간(b)과 오일유로(F)사이에 오일피스톤(30)의 움직임에 따라 토출공간(b)으로 유입된 오일을 오일유로(F)로 유입되도록 개폐하는 오일토출밸브(70)가 설치되며, 상기 흡입공간(a)측에 위치하는 오일실린더(20)의 단부에는 오일실린더(20)를 프레임(10)에 고정할 뿐만 아니라 흡입측 오일스프링(40)을 지지하는 흡입커버(80)가 결합되어 있다. 상기 오일토출밸브(70)는 얇은 두께와 일정 길이를 갖도록 형성되고, 상기 오일흡입밸브(60)는 얇은 두께를 갖는 원형으로 내부에 나선형의 홈(미도시)이 형성되어 있다.Then, the oil passage 31 of the oil piston 30 is opened and closed by the flow of the fluid by the reciprocating motion of the oil piston 30 between the discharge side oil spring 50 and one side of the oil piston 30 in contact with the discharge side oil spring 50. The oil suction valve 60 is inserted, and the oil introduced into the discharge space b as the oil piston F moves along the movement of the oil piston 30 between the discharge space b and the oil flow path F. An oil discharge valve 70 is installed to open and close so as to flow in. The oil cylinder 20 is fixed to the frame 10 at the end of the oil cylinder 20 positioned at the suction space a side, and the suction side oil is fixed. Suction cover 80 for supporting the spring 40 is coupled. The oil discharge valve 70 is formed to have a thin thickness and a predetermined length, and the oil suction valve 60 has a circular shape having a thin thickness and a spiral groove (not shown) is formed therein.

상기와 같이 구성된 종래 압축기의 오일공급장치는 다음과 같이 동작된다.The oil supply device of the conventional compressor configured as described above is operated as follows.

먼저, 압축기의 구동에 따라 전동기구부의 구동력이 축방향으로 직선 왕복운동하도록 작용하여 압축기구부에 전달되면 그 직선 왕복운동력을 압축기구부가 전달받아 가스를 흡입하여 압축하고 토출시키게 되며, 동시에 전동기구부 및 압축기구부에서 발생되는 축방향 진동이 오일공급장치에 전달된다.First, when the driving force of the electric mechanism part acts to linearly reciprocate in the axial direction according to the driving of the compressor, and the linear reciprocating force is transmitted to the compressor mechanism, the compressor mechanism receives the gas, compresses and discharges the gas, The axial vibration generated at the compression mechanism is transmitted to the oil supply device.

상기 오일공급장치에 전달되는 진동에 의해 오일실린더(20)의 내부에 움직임 가능하도록 삽입된 오일피스톤(30)이 오일실린더(20)와 상대운동하게 된다. 상기 오일피스톤(30)이 오일실린더(20)내부에서 흡입측 오일스프링(40)과 토출측 오일스프링(50)에 의해 탄성적으로 지지되면서 상대운동,즉 직선 왕복운동하면서 오일을 흡입공간(a)으로 흡입시켜 오일피스톤(30)의 오일통로(31) 및 오일흡입밸브(60)를 통해 토출공간(b)으로 유입시키고 이어 오일토출밸브(70)를 통해 오일유로(F)로 펌핑시키게 된다. 상기 오일유로(F)로 펌핑된 오일은 오일유로(F)를 따라 압축기구부 및 전동기구부에 공급된다. 이와 같은 과정이 지속적으로 반복되면서 밀폐용기(1)의 저면에 채워진 오일이 전동기구부 및 압축기구부에 공급 순환된다.The oil piston 30 inserted into the oil cylinder 20 to be movable by the vibration transmitted to the oil supply device is relative to the oil cylinder 20. The oil piston 30 is elastically supported by the suction-side oil spring 40 and the discharge-side oil spring 50 in the oil cylinder 20, and the oil is sucked in a relative motion, that is, a linear reciprocating motion (a). It is sucked into the oil passage 31 and the oil suction valve 60 of the oil piston 30 is introduced into the discharge space (b) and then pumped into the oil passage (F) through the oil discharge valve (70). The oil pumped into the oil passage F is supplied to the compression mechanism portion and the electric mechanism portion along the oil passage F. As the above process is continuously repeated, the oil filled in the bottom surface of the sealed container 1 is circulated in the power supply unit and the compression mechanism unit.

그러나, 상기와 같은 종래 압축기의 오일공급장치는 오일피스톤(30)의 직선 왕복운동에 의한 오일의 유동에 의해 개폐되는 오일흡입밸브(60) 및 오일토출밸브(70)가 각각 별도로 사용되어 부품수가 증가하게 되고, 아울러 부품수의 증가로 조립 공정이 증가하게 되는 단점이 있었다. 또한, 토출측 오일스프링(50)과 이에 접촉되는 오일피스톤(30)의 일측면사이에 삽입되는 오일흡입밸브(60)가 고정되어 있지 않아 오일피스톤(30)의 왕복운동시 그 위치가 이탈될 우려가 있었다.However, the oil supply device of the conventional compressor as described above, the oil suction valve 60 and the oil discharge valve 70 which is opened and closed by the flow of oil by the linear reciprocating motion of the oil piston 30 are used separately, so that the number of parts In addition, the assembly process is increased due to the increase in the number of parts. In addition, since the oil suction valve 60 inserted between the discharge side oil spring 50 and one side of the oil piston 30 in contact with the discharge side is not fixed, the position of the oil piston 30 may deviate during reciprocating movement. There was.

상기한 바와 같은 문제점을 감안하여 안출한 본 발명의 목적은 사용되는 부품수를 감소시킴과 아울러 조립 공정수를 줄이고, 밸브의 위치를 견고하게 고정할 수 있도록 한 압축기의 오일공급장치를 제공함에 있다.An object of the present invention devised in view of the above problems is to provide an oil supply device for a compressor that can reduce the number of parts used, reduce the number of assembly processes, and firmly fix the position of the valve. .

상기 오일이 펌핑되는 과정을 보다 구체적으로 설명하면, 먼저, 도 4a에 도시한 바와 같이, 오일피스톤(30)이 오른쪽(도면상)으로 이동하게 되면 흡입측 오일스프링(40)이 압축되고 토출측 오일스프링(50)이 인장되면서 원상태로 복귀되어 토출측 오일스프링(50)에 고정된 개폐부재(90)가 오일피스톤(30)과 일정 간격으로 떨어지게 되며 이와 동시에 오일실린더(20)의 흡입공간(a)내에 유입된 오일이 오일피스톤(30)의 오일통로(31)로 유동하면서 개폐부재(90)의 오일유동홈(93)을 통해 토출공간(b)으로 유입된다. 이어, 도 4b에 도시한 바와 같이, 오일피스톤(30)이 왼쪽(도면상)으로 이동하게 되면 흡입측 오일스프링(40)이 인장되고 동시에 오일피스톤(30)이 개폐부재(90)와 접촉되어 밀면서 토출공간(b)에 유입된 오일을 오일유로(F)로 펌핑시키게 된다. 이때 개폐부재(90)가 오일피스톤(30)의 오일통로(31)를 막은 상태가 되며 토출측 오일스프링(50)이 압축되고, 흡입공간(a)으로 오일이 유입된다. 그리고 이어 오일피스톤(30)이 오른쪽으로 이동하게 되며 이와 같은 과정을 반복하면서 오일유로(F)로 오일이 펌핑되며 오일유로(F)로 펌핑된 오일은 압축기구부 및 전동기구부로 공급된다.Referring to the process of pumping the oil in more detail, first, as shown in Figure 4a, when the oil piston 30 is moved to the right (in the drawing), the suction side oil spring 40 is compressed and the discharge side oil As the spring 50 is tensioned, it is returned to its original state, and the opening / closing member 90 fixed to the discharge side oil spring 50 falls at an interval with the oil piston 30, and at the same time, the suction space (a) of the oil cylinder 20 The oil introduced therein flows into the oil passage 31 of the oil piston 30 and flows into the discharge space b through the oil flow groove 93 of the opening and closing member 90. Subsequently, as shown in FIG. 4B, when the oil piston 30 moves to the left side (in the drawing), the suction side oil spring 40 is tensioned and the oil piston 30 is in contact with the opening and closing member 90. While pushing, the oil introduced into the discharge space (b) is pumped into the oil flow path (F). At this time, the opening and closing member 90 is in a state of blocking the oil passage 31 of the oil piston 30, the discharge side oil spring 50 is compressed, the oil is introduced into the suction space (a). Then, the oil piston 30 moves to the right side, and the oil is pumped into the oil channel F while repeating the above process, and the oil pumped into the oil channel F is supplied to the compressor mechanism and the electric mechanism part.

본 발명은 종래 오일흡입밸브(60) 및 오일토출밸브(70)를 사용하던 것을 배제하고 하나의 개폐부재(90)를 사용하게 되므로 부품수가 감소됨과 아울러 조립 공정수가 줄어들게 된다.The present invention eliminates the use of the conventional oil suction valve 60 and the oil discharge valve 70, so that one opening and closing member 90 is used, thereby reducing the number of parts and reducing the number of assembly processes.

또한, 본 발명은 개폐부재(90)가 토출측 오일스프링(50)에 고정되므로 오일피스톤(30)의 오일통로(31)를 개폐시 그 위치가 이탈되지 않고 오일통로(31)를 개폐하게 된다.In addition, in the present invention, since the opening and closing member 90 is fixed to the discharge side oil spring 50, when opening and closing the oil passage 31 of the oil piston 30, the position of the opening and closing of the oil passage 31 is opened and closed.

이상에서 설명한 바와 같이, 본 발명에 의한 압축기의 오일공급장치는 그 구성을 합리적으로 구성하여 부품을 감소시키게 됨으로써 조립 공정수를 감소시켜 조립 생산성을 향상시킬 뿐만 아니라 부품 원가를 절감시킬 수 있게 되며, 또한 부품의 이탈을 방지하여 정확한 오일 공급이 이루어지게 됨으로써 압축기의 작동이 원활하게 이루어지게 되는 효과가 있다.As described above, the oil supply device of the compressor according to the present invention can be reasonably configured to reduce the number of parts by reducing the number of assembling process to improve the assembly productivity as well as reduce the cost of parts, In addition, since the accurate oil supply is made by preventing the departure of parts, the operation of the compressor is made smoothly.
