본 발명은 로터리 압축기의 토출 밸브 장치에 관한 것으로서, 특히 블록밸브의 양측을 탄력지지하여 밸브동작을 안정화시키고 밸브타음을 더욱 줄인 로터리 압축기의 토출 밸브 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge valve device of a rotary compressor, and more particularly, to a discharge valve device of a rotary compressor in which both sides of a block valve are elastically stabilized to stabilize the valve operation and further reduce the valve sound.

일반적으로 리드형 토출밸브 조립체는 일단은 고정단으로 타단은 자유단으로 설치하여 밸브 양측의 압력차와 밸브 자체가 가진 탄성력에 의해 자유단이 고정단을 중심으로 각운동을 하면서 토출포트를 개폐하는 것으로, 통상 실린더의 토출측에 장착하여 압축실과 토출실의 압력차와 밸브의 탄성력에 의해 실린더의 토출포트를 개폐하면서 냉매가스의 토출을 조절하는 것이다.In general, the lead type discharge valve assembly has one end fixed and the other end free installed so that the free end opens and closes the discharge port by angular movement around the fixed end by the pressure difference between both sides of the valve and the elastic force of the valve itself. It is usually mounted on the discharge side of the cylinder to control the discharge of the refrigerant gas while opening and closing the discharge port of the cylinder by the pressure difference between the compression chamber and the discharge chamber and the elastic force of the valve.

이에 도시한 바와 같이 종래의 로터리 압축기는, 소정량의 오일을 채우고 가스흡입관(SP)과 가스토출관(DP)을 연통 설치하는 케이싱(1)과, 케이싱(1)의 상측에 설치하여 회전력을 발생하는 전동기구부와, 케이싱(1)의 하측에 설치하여 상기 전 동기구부에서 발생한 회전력으로 냉매를 압축하는 압축기구부로 구성하고 있다.As shown in the drawing, a conventional rotary compressor is provided with a casing (1) for filling a predetermined amount of oil and communicating a gas suction pipe (SP) and a gas discharge pipe (DP) with an upper side of the casing (1). And a compressor mechanism for compressing the refrigerant with the rotational force generated in the synchronizing mechanism provided at the lower side of the casing 1.

전동구동부는 케이싱(1)의 내부에 고정하여 외부에서 전원을 인가하는 고정자(Ms)와, 고정자(Ms)의 내부에 일정 공극을 두고 배치하여 상기한 고정자(Ms)와 상호 작용하면서 회전하는 회전자(Mr)로 이루어져 있다.The electric drive unit rotates while interacting with the stator Ms by fixing the inside of the casing 1 to stator Ms for applying power from the outside, and having a predetermined gap inside the stator Ms. It consists of electrons (Mr).

압축기구부는 환형으로 형성하여 케이싱(1)의 내부에 설치하는 실린더(2)와, 실린더(2)의 상하 양측을 복개하여 함께 내부공간을 형성하는 메인베어링(3) 및 서브베어링(4)과, 회전자(2)에 압입하고 메인베어링(3)과 서브베어링(4)에 지지되어 회전력을 전달하는 회전축(5)과, 회전축(5)의 편심부에 회전 가능하게 결합하여 실린더(2)의 내부공간에서 선회하면서 냉매를 압축하는 롤링피스톤(6)과, 롤링피스톤(6)의 외주면에 압접하도록 실린더(2)에 반경방향으로 이동 가능하게 결합하여 상기 실린더(2)의 내부공간(V)을 흡입실과 압축실로 구획하는 베인(미도시)과, 메인베어링(3)의 중앙부근에 구비한 토출포트(3b) 선단에 개폐 가능하게 결합하여 압축실에서 토출되는 냉매가스를 제한하는 토출밸브조립체(7)와, 토출밸브조립체(7)를 수용하도록 공명실을 구비하여 메인베어링(3)의 외측면에 설치하는 머플러(8)로 이루어져 있다.Compressor part is formed in an annular shape and the cylinder (2) to be installed inside the casing (1), the main bearing (3) and the sub-bearing (4) to cover the upper and lower sides of the cylinder (2) to form an inner space together; The cylinder (2) is rotatably coupled to the eccentric portion of the rotating shaft (5) and the rotating shaft (5), which is pressed into the rotor (2) and supported by the main bearing (3) and the sub-bearing (4) to transmit rotational force A rolling piston 6 that compresses the refrigerant while turning in the inner space of the inner surface of the cylinder 2 by moving radially to the cylinder 2 so as to be press-contacted to the outer circumferential surface of the rolling piston 6. ) And a vane (not shown) for dividing the suction into a suction chamber and a compression chamber, and a discharge valve for restricting the refrigerant gas discharged from the compression chamber by being openly coupled to the tip of the discharge port 3b provided near the center of the main bearing 3. A resonance chamber is provided to receive the assembly 7 and the discharge valve assembly 7. It consists of a muffler (8) installed on the outer surface of the main bearing (3).

메인베어링(3)은 중앙에 회전축(5)이 관통하여 반경방향으로 지지되는 축구멍(3a)을 형성하고, 그 축구멍(3a)의 일측 주변에는 압축실의 냉매가스를 고압부로 토출하는 토출포트(3b)를 형성하고 있다.The main bearing 3 forms a shaft hole 3a through which the rotating shaft 5 penetrates radially in the center thereof, and discharges refrigerant gas in the compression chamber to the high pressure part around one side of the shaft hole 3a. The pot 3b is formed.

토출밸브조립체(7)는 도 2에서와 같이 메인베어링(3)의 토출포트(3b)를 개폐하도록 상기 메인베어링(3)의 외측면에 고정하는 토출밸브(7a)와, 토출밸브(7a)의 후위에서 함께 메인베어링(3)에 고정하여 상기 토출밸브(7a)의 열림량을 제한하는 리테이너(7b)로 이루어져 있다.The discharge valve assembly 7 has a discharge valve 7a fixed to the outer side of the main bearing 3 so as to open and close the discharge port 3b of the main bearing 3 as shown in FIG. 2, and the discharge valve 7a. The retainer 7b is fixed to the main bearing 3 together at the rear side thereof to limit the opening amount of the discharge valve 7a.

토출밸브(7a)는 소정의 탄성을 가지는 얇은 강판을 장방형으로 형성하고, 그 일단은 상기한 리테이너(7b)와 함께 메인베어링(7a)에 고정하는 고정단을 이루는 반면 타단은 메인베어링(3)의 토출포트(3a)를 개폐하는 자유단으로 형성하고 있다.The discharge valve 7a forms a thin steel plate having a predetermined elasticity in a rectangular shape, one end of which forms a fixed end fixed to the main bearing 7a together with the retainer 7b described above, while the other end thereof is the main bearing 3. Is formed at the free end for opening and closing the discharge port 3a.

리테이너(7b)는 소정의 강성을 가지는 두꺼운 강판을 역시 장방형으로 형성하고, 그 일단은 상기한 토출밸브(7a)와 함께 메인베어링(3)에 밀착하여 고정하는 직선부를 이루는 반면 타단은 토출밸브(7a)의 압력배면과 일정 간격을 두되 그 토출밸브(7a)의 휘어지는 형상대로 곡면을 이루는 곡선부로 형성하고 있다.The retainer 7b is also formed in a rectangular steel plate having a predetermined rigidity, one end of which forms a straight portion which is tightly fixed to the main bearing 3 together with the above-described discharge valve 7a, while the other end thereof is a discharge valve ( It is formed as a curved part which has a predetermined space | interval with the pressure back surface of 7a), and forms a curved surface in the curved shape of the discharge valve 7a.

도면중 미설명 부호인 2a는 흡입구, 7c는 고정볼트이다.In the figure, reference numeral 2a denotes an inlet port, and 7c denotes a fixed bolt.

상기와 같은 종래 로터리 압축기는 다음과 같이 동작한다.The conventional rotary compressor as described above operates as follows.

즉, 전동기구부의 고정자(Ms)에 전원을 인가하여 회전자(Mr)가 회전하면, 압축기구부의 회전축(5)이 회전자(Mr)와 함께 회전하고, 롤링피스톤(6)이 실린더(2)의 내부공간(V)에서 편심 회전하며, 롤링피스톤(6)의 편심 회전에 따라 냉매가스가 흡입실로 흡입되어 일정압력까지 지속적으로 압축되다가 압축실 압력이 케이싱(1)내의 압력보다 고압이 되는 순간 메인베어링(3)의 토출포트(3b)와 머플러(8)를 통해 케이싱(1)으로 토출된다.That is, when the rotor (Mr) is rotated by applying power to the stator (Ms) of the electric mechanism part, the rotating shaft (5) of the compression mechanism part rotates together with the rotor (Mr), and the rolling piston (6) is the cylinder (2). Eccentrically rotates in the inner space (V), and the refrigerant gas is sucked into the suction chamber according to the eccentric rotation of the rolling piston (6) and continuously compressed to a predetermined pressure, and the compression chamber pressure becomes higher than the pressure in the casing (1). Instantaneous discharge is carried out to the casing 1 via the discharge port 3b and the muffler 8 of the main bearing 3.

이때, 토출포트(3b)의 출구측에는 리드형 토출밸브 조립체가 설치되어 압축실의 압력이 일정 압력 이상이 되면 그 압축실의 압력에 밀려 토출밸브(7a)가 휘어지면서 상기한 토출포트(3b)가 열려 압축된 냉매가스가 토출되도록 하는 반면 압축 실의 압력이 일정 압력 이하가 되면 다시 토출밸브(7a)가 복원되면서 상기한 토출포트(3b)를 닫는 것이었다.At this time, a lead-type discharge valve assembly is installed at the outlet side of the discharge port 3b, and when the pressure in the compression chamber is equal to or higher than a predetermined pressure, the discharge valve 7a is bent by the pressure in the compression chamber, and the discharge port 3b is described above. Is opened to allow the compressed refrigerant gas to be discharged, but when the pressure in the compression chamber is lower than the predetermined pressure, the discharge valve 7a is restored again to close the discharge port 3b.

이와 같은 종래 리드형 토출밸브에 있어서는 토출밸브(7a)가 열리고 닫힐 때 각각 리테이너(7b)와 밸브시트(미부호)에 부딪혀 밸브타음 유발하고, 압축손실이 발생하여 압축효율이 저하되는 동시에 초기기동시의 작동불량이 증가되어 압축성능이 나빠지는 문제점이 있었다. 또, 토출밸브(7a)가 리테이너(7b)나 밸브시트에 부딪힘에 따라 내구성이 저하되는 문제점도 있었다.In the conventional lead-type discharge valve, when the discharge valve 7a is opened and closed, it hits the retainer 7b and the valve seat (unsigned), respectively, causing the valve to burn, and a compression loss occurs, thereby reducing the compression efficiency and initial starting. There was a problem that the compression performance worsens due to an increase in the poor operation. In addition, there was a problem in that durability decreases as the discharge valve 7a collides with the retainer 7b or the valve seat.

이러한 단점을 감안하여 본 출원인이 2000.05.08.자로 출원한 (출원번호:2000-24452호) "로터리 압축기의 토출 밸브 장치"는 도 3에서와 같이 실린더(10)의 베인슬릿(미도시) 일측에 토출포트(11)와 이에 연결하여 밸브안착부(12)를 형성하고 밸브안착부(12)에 연통하도록 메인베어링(20)에는 토출공(21)을 형성하며 실린더(10)의 밸브안착부(12)에는 상기 토출포트(11)와 토출공(21)을 개폐하는 블록밸브(30)를 미끄러지게 삽입하되 이 블록밸브(30)의 일측에는 압축스프링으로 된 탄성부재(40)를 두어 구성하는 것이었다.In view of these shortcomings, the applicant of the present application filed on May 8, 2000 (application number: 2000-24452) "discharge valve device of the rotary compressor" is one side of the vanes (not shown) of the cylinder 10 as shown in FIG. The discharge port 11 is connected to the discharge port 11 to form a valve seat 12, and the discharge hole 21 is formed in the main bearing 20 so as to communicate with the valve seat 12, and the valve seat of the cylinder 10. 12, the block valve 30 for slidingly opening and closing the discharge port 11 and the discharge hole 21 is slidably inserted, but one side of the block valve 30 has an elastic member 40 made of a compression spring. It was.

그러나, 상기와 같은 종래 로터리 압축기의 토출 밸브 장치는, 리드밸브를 대신한 블록밸브(30)가 내부공간(V)의 압력과 탄성부재(40)의 탄성력 차에 따라 상기한 밸브안착부(12)에서 미끄럼운동을 하면서 토출포트(11)와 토출공(21)을 개폐하는 것으로 실제 밸브타음과 압축손실을 줄이는 동시에 밸브의 내구성을 향상시킬 수 있다는 장점은 있으나, 상기 블록밸브(30)가 내부공간(V)에서 토출포트(11)를 통해 유입되는 압축가스에 의해 열렸다가 탄성부재(340)의 탄성력에 의해서만 닫힘 에 따라 밸브의 거동이 불안정해지면서 오히려 압축성능이 저하될 우려가 있었다. 즉, 블록밸브(30)가 한 개의 탄성부재(40)에 의해 한 쪽만 지지됨에 따라 이 탄성부재(40)의 강성이 과도한 경우에는 블록밸브(30)가 닫히는 속도는 빨라지나 열리는 속도는 지연되어 압축손실이 발생할 우려가 있는 반면 탄성부재(40)의 강성이 낮은 경우에는 블록밸브(30)가 열리는 속도는 빨라지나 반대로 닫히는 속도가 지연되어 냉매가스의 누설로 인한 흡입손실을 유발할 우려가 있었다.However, in the discharge valve device of the conventional rotary compressor as described above, the valve seat portion 12 according to the pressure difference of the internal space (V) and the elastic force of the elastic member 40 is replaced by the block valve 30 instead of the reed valve. By opening and closing the discharge port 11 and the discharge hole (21) while sliding in the) there is an advantage that can reduce the actual valve sounding and compression loss while improving the durability of the valve, the block valve 30 is inside Opening by the compressed gas flowing through the discharge port 11 in the space (V), but closed only by the elastic force of the elastic member 340, the behavior of the valve is unstable, there was a fear that the compression performance deteriorated. That is, when only one side of the block valve 30 is supported by one elastic member 40, when the rigidity of the elastic member 40 is excessive, the speed at which the block valve 30 closes is increased but the opening speed is delayed. When the compression loss may occur, but the rigidity of the elastic member 40 is low, the speed at which the block valve 30 opens may be increased, but the closing speed may be delayed, causing suction loss due to leakage of refrigerant gas.

또, 탄성부재(40)의 강성에 따라서는 블록밸브(30)가 밸브안착부(12)의 토출포트(11)측 턱에 강하게 부딪혀 밸브타음을 유발할 우려도 있었다.In addition, depending on the rigidity of the elastic member 40, the block valve 30 is strongly hit against the jaw of the discharge port 11 side of the valve seat 12 may cause a valve sound.

본 발명은 상기와 같은 종래 로터리 압축기의 토출 밸브 장치가 가지는 문제점을 감안하여 안출한 것으로, 토출밸브의 거동을 안정화시켜 압축성능을 높일 수 있는 로터리 압축기의 토출 밸브 장치를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the discharge valve device of the conventional rotary compressor as described above, to provide a discharge valve device of the rotary compressor that can increase the compression performance by stabilizing the behavior of the discharge valve. have.

도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

상기와 같은 본 발명 로터리 압축기의 토출 밸브 장치는 다음과 같이 작동한 다.The discharge valve device of the rotary compressor of the present invention as described above operates as follows.

먼저, 전동기구부에 전원이 인가되어 회전축(5)이 회전을 하면, 회전축(5)의 편심부에 결합한 롤링피스톤(6)이 실린더(110)의 내부공간(V)에서 선회운동을 하면서 그 내부공간(V)의 체적을 변화시키고, 이에 따라 냉매가스가 실린더(110)의 흡입구(111)를 통해 내부공간(V)으로 흡입되었다가 롤링피스톤(6)을 따라 이동을 하다가 베인(9)에 막혀 압축되어 밸브하우징(130)의 토출포트(132)와 메인베어링(120)의 토출공(122)을 통해 케이싱(1)으로 토출된다.First, when the power is applied to the power mechanism to rotate the rotary shaft 5, the rolling piston 6 coupled to the eccentric portion of the rotary shaft 5 is pivoting in the internal space (V) of the cylinder 110, the inside thereof By changing the volume of the space (V), the refrigerant gas is sucked into the inner space (V) through the inlet 111 of the cylinder 110, and moves along the rolling piston (6) to the vane (9) It is blocked and compressed and discharged to the casing 1 through the discharge port 132 of the valve housing 130 and the discharge hole 122 of the main bearing 120.

이때, 도 6a에서와 같이 롤링피스톤(6)이 흡입행정을 실시하는 중에는 냉매가스가 흡입구(111)를 통해 실린더(110)의 내부공간(즉, 흡입영역)(V)으로 흡입되어 일부는 그 내부공간(V)을 따라 점차 압축되면서 이동하는 반면 일부는 흡입포트(131)를 통해 밸브하우징(130)으로 흡입되어 그 밸브하우징(130)의 제1 탄성부재(151)와 함께 블록밸브(140)를 토출포트(132)쪽으로 밀어낸다. 제2 탄성부재(152)가 압축되면서 블록밸브(140)가 토출포트(132)쪽으로 밀려 토출공(122)을 차단함으로써 실린더(110)의 내부공간(즉, 압축영역)(V)이 밀폐되면서 냉매가스를 소정의 압력까지 압축을 진행하게 된다.At this time, while the rolling piston 6 performs the suction stroke as shown in FIG. 6A, the refrigerant gas is sucked into the internal space (ie, the suction area) V of the cylinder 110 through the suction port 111, and a part thereof While moving gradually while being compressed along the inner space (V), some are sucked into the valve housing 130 through the suction port 131 and block valve 140 together with the first elastic member 151 of the valve housing 130. ) Is pushed toward the discharge port 132. As the second elastic member 152 is compressed, the block valve 140 is pushed toward the discharge port 132 to block the discharge hole 122, thereby closing the inner space (ie, the compressed region) V of the cylinder 110. The refrigerant gas is compressed to a predetermined pressure.

다음, 도 6b에서와 같이 롤링피스톤(6)이 더 선회운동을 하여 압축행정을 실시할 때는 실린더(110)의 내부공간(V) 중에서 압축영역의 냉매가스 일부가 토출포트(132)를 통해 밸브하우징(130)의 밸브안착부(133)로 지속적으로 유입되어 제2 탄성부재(152)와 함께 블록밸브(140)를 흡입포트(131)쪽으로 밀어내고, 이에 따라 제2 탄성부재(152)는 복원되는 반면 제1 탄성부재(151)가 압축되어 블록밸브(140) 가 흡입포트(131) 방향으로 밀려나면서 토출공(122)이 열려 실린더(110)의 압축영역에서 압축되던 냉매가스가 상기한 토출포트(132)와 밸브안착부(133) 그리고 토출공(122)을 거쳐 케이싱(1)의 내부로 토출되는 것이다.Next, as shown in FIG. 6B, when the rolling piston 6 performs a further rotational movement to perform the compression stroke, a part of the refrigerant gas in the compression region is discharged through the discharge port 132 in the internal space V of the cylinder 110. Continuously flows into the valve seating portion 133 of the housing 130 to push the block valve 140 together with the second elastic member 152 toward the suction port 131, whereby the second elastic member 152 is On the other hand, while the first elastic member 151 is compressed and the block valve 140 is pushed toward the suction port 131, the discharge hole 122 is opened and the refrigerant gas compressed in the compression region of the cylinder 110 is described. The discharge port 132, the valve seating portion 133, and the discharge hole 122 are discharged into the casing 1.

이렇게 하여, 블록밸브가 그 양쪽의 탄성부재의 탄성력과 함께 흡입포트와 토출포트를 통해 상기 블록밸브의 양쪽으로 유입되는 냉매가스의 압력차에 의해 미끄럼운동을 하면서 상기한 토출공을 개폐함에 따라 블록밸브의 거동이 안정되고 이를 통해 압축기의 압축성능이 크게 향상되는 것은 물론 블록밸브의 전후 양측에 구비하는 탄성부재와 양쪽으로 유입되는 냉매가스가 블록밸브와 밸브하우징 사이를 완충하여 밸브타음을 현저하게 줄일 수 있다.In this way, the block valve opens and closes the discharge hole while sliding by the pressure difference between the refrigerant gas flowing into the block valve through the suction port and the discharge port together with the elastic force of both elastic members. The valve's behavior is stabilized and the compressor's compression performance is greatly improved, and the elastic members provided on both sides of the block valve and the refrigerant gas flowing into both sides of the valve valve buffer the valve valve and the valve housing. Can be reduced.

본 발명에 의한 로터리 압축기의 토출 밸브 장치는, 흡입포트와 토출포트에 연통하는 밸브하우징의 밸브안착부에 블록밸브를 미끄러지게 삽입하고, 이 블록밸브의 양측에 각각 탄성부재를 개재하여 상기 탄성부재의 탄성력과 양쪽 포트로 유입된 냉매가스의 압력차로 상기한 블록밸브를 개폐함으로써, 블록밸브의 거동이 안정되어 압축기의 압축성능이 크게 향상되는 것은 물론 블록밸브의 전후 양측에 구비하는 탄성부재와 양쪽으로 유입되는 냉매가스가 블록밸브와 밸브하우징 사이를 완충하여 상기한 블록밸브의 개폐시 밸브타음을 현저하게 줄일 수 있다.In the discharge valve device of the rotary compressor according to the present invention, a block valve is slidably inserted into a valve seating portion of a valve housing communicating with a suction port and a discharge port, and the elastic member is provided on both sides of the block valve via an elastic member. By opening and closing the block valve by the elastic force and the pressure difference between the refrigerant gas flowing into both ports, the behavior of the block valve is stabilized, which greatly improves the compression performance of the compressor, as well as the elastic member provided on both sides of the block valve. Refrigerant gas flowing into the buffer between the block valve and the valve housing can significantly reduce the valve batting when opening and closing the block valve.
