본 발명은 압축기의 압축구조에 관한 것으로, 특히 흡입관 압축이 연속적으로 동일한 싯점에서 일어나도록 함으로써 압력의 불균형에 의한 진동을 없애고 토출압력도 맥동없이 일정하게 유지되어 압축효율을 증가시킬 수 있는 압축기의 압축구조에 관한 것이다.The present invention relates to a compression structure of a compressor, and in particular, the suction pipe compression to occur at the same point continuously to eliminate the vibration caused by the pressure imbalance and the discharge pressure is also kept constant without pulsation compression of the compressor that can increase the compression efficiency It's about structure.

종래에는 압축되어 토출되는 유체의 압력이 펄스(Pulse)로 나타나기 때문에 압력의 불균형에 의해 진동이 발생된다.Conventionally, since the pressure of a fluid compressed and discharged is represented by a pulse, vibration is generated by an unbalance of pressure.

즉, 흡입과 압축이 번갈아 가면서 일어나기 때문에 도시된 제7도와 같이 토출압력이 압축시에만 나타나게 되고, 이로 인하여 압축기의 압력이 불균형을 이루어 진동이 발생됨은 물론, 압축효율도 저하된다는 문제점이 있었다.That is, since the suction and the compression occurs alternately, the discharge pressure appears only at the compression as shown in FIG. 7, and thus, the pressure of the compressor is imbalanced, thereby causing vibration, as well as the compression efficiency.

따라서, 본 발명은 상기 문제점을 해결하기 위하여 이루어진 것으로써, 본 발명의 목적은, 흡입과 압축이 연속적으로 동일한 싯점에서 일어나도록 사인곡률을 갖는 회전부재의 상·하측에 각각 2개씩 날개부재가 스프링을 매개로 상·하 작동되게 함으로써 압력의 불균형의 의한 진동을 없애고 토출압력도 맥동없이 일정하게 유지되어 압축효율을 증가시킬 수 있는 압축기의 압축구조를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention, two wing members each spring on the upper and lower sides of the rotating member having a sinusoidal curvature so that suction and compression occur continuously at the same seat point. It is to provide a compression structure of the compressor to increase the compression efficiency by eliminating the vibration caused by the imbalance of pressure by maintaining the operation up and down through the media, and to maintain a constant discharge pressure without pulsation.

The rotating shaft 2 is press-fitted, and the rotating member 3 coupled to the rotating disk 1 and the rotating shaft 2 in this way is rotatably installed while being installed inside through the lower side of the cylindrical cylinder 5 installed in the compressor. It is.

이때, 상기 원통형 실린더(5)는 상기 회전부재(3)를 수용할 수 있도록 상부실린더(5a)와 하부실린더(5b)로 이루어져서 그 내부중앙에 압축실(5c)이 형성되어 있고, 이 압축실(5c)의 상·하부중앙에는 상기 회전축(2)이 끼워지도록 관통되는 축홀(5d)(5e)이 뚫어져 있으며, 그 압축실(5c)내에서는 상기 회전원판(1)이 회전되면서 사인곡률에 따라 흡입된 유체를 압축시켜 토출되도록 4개의 흡입구(5f)(5f')(5f)(5f')와 4개의 토출구(5g)(5g')(5g)(5g')가 원통형 실린더(5)의 외부와 통하게 각각 뚫어져 있다.At this time, the cylindrical cylinder (5) is composed of an upper cylinder (5a) and a lower cylinder (5b) to accommodate the rotating member 3, the compression chamber (5c) is formed in the inner center, this compression chamber In the upper and lower centers of 5c, shaft holes 5d and 5e are formed to penetrate the rotary shaft 2, and in the compression chamber 5c, the rotary disk 1 is rotated to have a sinusoidal curvature. The four suction ports 5f, 5f ', 5f and 5f' and the four discharge ports 5g, 5g ', 5g and 5g' are compressed to discharge the sucked fluid. It is perforated with the outside of each.

또, 상기 원통형 실린더(5)의 외부둘레에는 압축시 토출구(5g)(5g')(5g)(5g')에선 발생하는 소음을 흡수할 수 있도록 머플러카바(6a)(6b)(6c)(6d)가 각각 설치되어 있고, 이 머플러카바(6a)(6b)(6c)(6d)내에는 상기 토출구(5g)(5g')(5g)(5g')를 통해 토출되는 유체가 역류되는 것을 방지하도록 토출밸브(7)가 각각 설치되어 있으며, 또한 상기 4개의 머플러카바(6a)(6b)(6c)(6d)가 서로 한쌍으로 연결되어서 4개의 토출구(5g)(5g')(5g)(5g')에서 발생한 압축가스를 취합하여 냉장싸이클로 공급하도록 되어 있다.In addition, the outer periphery of the cylindrical cylinder (5) muffler cover (6a) (6b) (6c) (so as to absorb the noise generated in the discharge port (5g) (5g ') (5g) (5g') during compression ( 6d) are respectively provided, and the fluid discharged through the discharge ports 5g, 5g ', 5g and 5g' is reversed in the muffler covers 6a, 6b, 6c and 6d. Discharge valves 7 are provided to prevent each other, and the four muffler covers 6a, 6b, 6c, and 6d are connected to each other in pairs so that the four discharge ports 5g, 5g ', and 5g are connected. Compressed gas generated at 5g 'is collected and supplied to the refrigeration cycle.

이때, 흡입을 위한 머플러는 본 발명에서 도시되어 있지 않으며, 통상 흡입머플러를 적용하지 않는 경우도 있다.At this time, the muffler for suction is not shown in the present invention, there is a case that usually does not apply a suction muffler.

또한, 상기 원통형 실린더(5)의 압축기(5c) 상·하측에는, 회전축(2)의 회전력을 전달받아 동시에 회전되는 회전원판(1)의 사인곡률에 따라 면접촉되면서 상·하작동되도록 스프링(8)을 매개로 날개부재(9a)(9b)(9c)(9d)가 각각 설치되어 있다.In addition, the upper and the lower side of the compressor (5c) of the cylindrical cylinder (5) is received by the rotational force of the rotating shaft (2) in accordance with the sinusoidal curvature of the rotating disk (1) rotated at the same time while the spring ( 8, the wing members 9a, 9b, 9c, and 9d are provided, respectively.

즉, 상기 압축실(5c)내에 회전가능케 설치된 회전원판(1)의 상측에는 회전축(2)을 중심으로 각각 180°의 위치에 상기 날개부재(9a)(9b)가 설치되어서 상·하작동되도록 안내하는 안내홈(5a')이 압축실(5c)의 상부면에 각각 형성되어 있고, 상기 회전원판(1)의 하측에는 상기 회전원판(1)의 상부측에 설치된 날개부재(9a)(9b)와 각각 직각(90°)을 이루도록 회전축(2)을 중심으로 각각 180°의 위치에 날개부재(9c)(9d)가 설치되어서 상·하작동되도록 안내하는 안내홈(5b')이 압축실(5c)의 하부면에 각각 형성되어 있으며, 이들 안내홈(5a')(5b')은 회전축(2)과 압축실(5c) 내벽과의 거리만큼 각각 압축실(5c) 상·하측면에 홈이 형성되어있어, 이 홈에 대응하는 폭만큼 길이를 갖는 날개부재(9a)(9b)(9c)는 스프링(8)을 매개로 상기 안내홈(5a')(5b')에 각각 삽입되어서 스프링(8)의 탄성력에 상·하작동되도록 되어있다.That is, the wing member (9a) (9b) is installed on the upper side of the rotating disk (1) rotatably installed in the compression chamber (5c) at a position of 180 degrees around the rotating shaft (2) so that the up and down operation Guide grooves 5a 'for guiding are formed on the upper surface of the compression chamber 5c, respectively, and wing members 9a and 9b provided on the upper side of the rotary disk 1 below the rotary disk 1, respectively. Wing member 9c, 9d is installed at a position of 180 ° around the rotating shaft 2 so as to form a right angle (90 °), respectively. Each of the guide grooves 5a 'and 5b' is formed on the upper and lower sides of the compression chamber 5c by the distance between the rotary shaft 2 and the inner wall of the compression chamber 5c. Grooves are formed, and wing members 9a, 9b, 9c having a length corresponding to the grooves are respectively inserted into the guide grooves 5a ', 5b' through the springs 8, Spring force of spring (8) Is such that the upper and the lower work.

이때, 상기 날개부재(9a)(9b)(9c)(9d)는 상기 흡입구(5f)(5f')(5f)(5f')와 토출구(5g)(5g')(5g)(5g')와의 사이에 위치되도록 되어있어, 날개부재(9a)(9b)(9c)(9d)를 전후로 발생되는 체적변화에 따라 흡입 및 압축이 일어나도록 되어 있다.At this time, the wing members 9a, 9b, 9c, and 9d are the suction ports 5f, 5f ', 5f, 5f', and the discharge ports 5g, 5g ', 5g', 5g ', and 5g', respectively. It is located between and, so that suction and compression are performed in accordance with the volume change generated before and after the wing members 9a, 9b, 9c, and 9d.

다음에는, 상기와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Next, the operational effects of the present invention configured as described above are as follows.

제1도 내지 제6도에 있어서, 도시하지 않은 회전수단에 의해서 회전축(2)이 회전하게 되면, 이 회전축(2)과 고정부착된 회전원판(2)이 제4도와 같이 사인곡률을 형성하면서 회전되어, 날개부재(9a)(9b)(9c)(9d)에 의해 감소하게 되므로 S부분에 있는 유체의 압력이 토출구(5g)(5g')(5g)(5g')를 통해 토출된다. 이때 R부분의 체적은 증가됨으로 흡입구(5f)(5f')(5f)(5f')를 통하여 외부에서 압축실(5c)의 R부분으로 유체가 흡입되게 된다.1 to 6, when the rotating shaft 2 is rotated by a rotating means (not shown), the rotating shaft 2 and the rotating disk 2 fixedly attached form a sinusoidal curvature as shown in FIG. It is rotated and is reduced by the wing members 9a, 9b, 9c, and 9d, so that the pressure of the fluid in the S portion is discharged through the discharge ports 5g, 5g ', 5g, 5g'. At this time, the volume of the R portion is increased so that the fluid is sucked into the R portion of the compression chamber 5c from the outside through the suction ports 5f, 5f ', 5f, 5f'.

또, 상기 회전원판(1)의 제4도의 (다)도에 위치하게 되면, 압축실(5c)의 S 및 R부분의 공간은 동일체적내에 위치하게 되므로 (가)도에서 (나)도까지 압축되어 토출된 고압의 유체는 상기 토출구(5g)(5g')(5g)(5g')를 통하여 압축실(5c)로 역류되어 S 및 R부분의 공간으로 유입되게 된다. 이때 이를 방지하기 위하여 각각의 토출구(5g)(5g')(5g)(5g')에는 토출밸브(7)를 설치하면서 토출된 유체가 역류되는 것을 방지한다.In addition, when it is located in (C) of FIG. 4 of the rotating disc 1, the spaces of the S and R portions of the compression chamber 5c are located in the same volume, so that from (A) to (B) The compressed and discharged high pressure fluid flows back into the compression chamber 5c through the discharge ports 5g, 5g ', 5g and 5g' and flows into the spaces of the S and R portions. At this time, in order to prevent this, the discharged fluid is prevented from flowing backward while installing the discharge valve 7 in each of the discharge ports 5g, 5g ', 5g, and 5g'.

또한, 상기 회전원판(1)이 제4도의 (다)도에 위치해서 (라)도의 위치로 회전되면, (가)도에서 (다)도까지 압축이 일어나던 압축실(5c)의 S부분의 공간이 날개부재(9a)(9b)(9c)(9d)를 지나 흡입위치가 되고, 계속해서 회전원판(1)이 표시된 화살표방향으로 회전하면, R부분의 공간이 체적이 커지게 되므로 R부분의 공간에는 흡입구(5f)(5f')(5f)(5f')를 통해 유체가 흡입됨과 동시에 S부분의 공간은 체적이 감소되어 (가)(나)(다)(라)도와 같은 순서로 반복되어 흡입과 압축이 이루어진다.In addition, when the rotating disc 1 is rotated to the position of (d) in FIG. 4 (d), the portion S of the compression chamber 5c where compression occurs from (a) to (d) If the space of the blade passes through the wing members 9a, 9b, 9c, and 9d, and becomes the suction position, and the rotary disc 1 is rotated in the direction indicated by the arrow, the space of the R portion becomes large, In the space of the part, the fluid is sucked through the inlets 5f, 5f ', 5f, and 5f', and the space of the S part is reduced in volume so that the order of (a) (b) (c) (d) is reduced. It is repeated with suction and compression.

이때, 압축실(5c)의 상부면에 설치된 날개부재(9a)(9b)와, 압축실(5c)의 하부측에 설치된 날개부재(9c)(9d)는 회전원판(1)을 중심으로 상·하측에서 180°로 교차되는 위치에 각각 설치되어있으므로 회전원판(1)을 중심으로 압축실(5c)의 상부측 공간이 압축될때 하부측 공간에는 유체가 흡입되는 상태가 되고 상부측공간에 유체가 흡입될때 하부측공간에는 압축이 이루어지는 상호 반복행정을 하게 된다.At this time, the wing members 9a and 9b provided on the upper surface of the compression chamber 5c, and the wing members 9c and 9d provided on the lower side of the compression chamber 5c are positioned above the rotating disc 1, respectively. Since it is installed at the position intersected at 180 ° from the lower side, when the upper space of the compression chamber 5c is compressed around the rotating disc 1, the fluid is sucked into the lower space and the fluid is supplied to the upper space. When is inhaled, the lower side space is subjected to a mutually repeated stroke of compression.

한편, 압축기의 토출압력은 회전원판(1)을 중심으로 압축실(5c)내의 상·하측에 각각 형성된 4개의 체적(공간)이 제5도와 같이 주기 1/2T로 중첩되게 나타난다. 그러므로 본 발명의 압축기의 토출압력은 제6도와 같이 개개의 압력 P의 2배인 2P로 연속적으로 반복되게 나타나므로 압력차에 의한 진동이 발생되지 않고 압축효율도 증가되는 것이다.On the other hand, the discharge pressure of the compressor is shown so that four volumes (spaces) formed respectively in the upper and lower sides of the compression chamber 5c around the rotating disc 1 overlap each other in the period 1 / 2T as shown in FIG. Therefore, since the discharge pressure of the compressor of the present invention appears to be continuously repeated at 2P, which is twice the individual pressure P as shown in FIG. 6, the vibration is not generated by the pressure difference and the compression efficiency is also increased.

이상에서 설명한 바와같이 본 발명의 압축기의 압축구조는, 흡입과 압축이 연속적으로 동일한 싯점에서 일어나도록 사인곡률를 갖는 회전부재의 상·하측에 각각 2개씩 날개부재가 스프링을 매개로 상·하작동되게 함으로써 압력의 불균형에 의한 진동을 없앨수 있고, 또 토출압력도 맥동없이 일정하게 유지되어 압축효율을 증가시킬 수 있는 효과가 있다.As described above, in the compression structure of the compressor of the present invention, two wing members are operated on the upper and lower sides of a rotating member having a sinusoidal curvature so that suction and compression occur continuously at the same seat point. As a result, the vibration due to the pressure imbalance can be eliminated, and the discharge pressure is also kept constant without pulsation, thereby increasing the compression efficiency.
