이에 도시한 바와 같이 종래의 관성형 압축용 흡입밸브 조립체는, 왕복동식 모터(미도시)의 가동자에 결합하여 함께 직선으로 왕복운동을 하는 피스톤(10)과, 피스톤(10)의 흡입유로(12)를 개폐하는 흡입밸브(20)와, 흡입밸브(20)를 피스톤에 고정하는 체결너트(30)로 구성하고 있다.As shown in the related art, the conventional inertial compression suction valve assembly includes a piston 10 coupled to an actuator of a reciprocating motor (not shown) and linearly reciprocating together, and a suction flow path of the piston 10 ( 12, the suction valve 20 which opens and closes, and the fastening nut 30 which fixes the suction valve 20 to a piston are comprised.
피스톤(10)은 피스톤 몸체(11)의 내부를 축방향으로 관통하는 흡입유로(12)를 형성하고, 흡입유로(12)의 출구측 끝단에는 흡입밸브(20)에 의해 개폐하는 흡입통구(13)를 형성하며, 흡입통구(13)의 안쪽에는 흡입밸브(20)를 지지하기 위한 걸림돌부(14)를 형성하고 있다.The piston 10 forms a suction passage 12 penetrating the inside of the piston body 11 in the axial direction, and the suction passage 13 opened and closed by the suction valve 20 at an outlet side end of the suction passage 12. ) Is formed, and an engaging protrusion 14 for supporting the suction valve 20 is formed inside the suction port 13.

It is formed in the rectangular shape when the front projection so as to be integrally connected to the piston body 11, the sliding shaft passes through the support shaft 22 of the suction valve 20 in the center so that the fastening nut 30 is caught from the inside (Unsigned) is formed.
흡입밸브(20)는 흡입통구(13)를 개폐하는 실링부(21)와, 실링부(21)의 안쪽면 중앙에서 돌출 형성하여 피스톤의 걸림돌부(14)를 관통하는 지지축부(22)로 이루어져 있다.The suction valve 20 is a sealing portion 21 for opening and closing the suction port 13 and the support shaft portion 22 protruding from the center of the inner surface of the sealing portion 21 to penetrate the locking protrusion 14 of the piston. consist of.

도면중 미설명 부호인 1은 실린더, 2는 토출밸브 조립체, 2A는 밸브하우징, 2B는 토출밸브, 2C는 밸브스프링, S1은 압축공간, S2는 토출공간이다.In the drawings, reference numeral 1 denotes a cylinder, 2 a discharge valve assembly, 2A a valve housing, 2B a discharge valve, 2C a valve spring, S1 a compression space, and S2 a discharge space.
상기와 같은 종래 압축용 흡입밸브 조립체는 다음과 같이 동작한다.The conventional compression suction valve assembly as described above operates as follows.
즉, 피스톤이 왕복동식 모터(미도시)의 가동자와 함께 직선으로 왕복운동을 하면, 도 2 및 도 3에서와 같이 흡입밸브(20)가 자체 관성과 흡입유로(12)를 통한 냉매가스의 압력에 밀리면서 피스톤(10)의 걸림돌부(14)에 구비한 미끄럼 구멍(미부호)을 따라 흡입밸브(20)의 지지축부(22)가 미끄러져 이동하고, 이 과정에서 흡입밸브(20)가 피스톤(10)의 흡입통구(13)를 열어 냉매가스를 압축공간(S1)으로 안내하거나 피스톤(10)의 흡입통구(12)를 닫아 압축공간(S1)으로 유입하는 냉매가스를 것을 차단한다.That is, when the piston reciprocates linearly with the mover of the reciprocating motor (not shown), as shown in FIGS. 2 and 3, the intake valve 20 has its own inertia and the refrigerant gas through the suction passage 12. While supporting the pressure, the support shaft 22 of the suction valve 20 slides along the sliding hole (unsigned) provided in the locking portion 14 of the piston 10, and in this process, the suction valve 20 Opens the suction port 13 of the piston 10 to guide the refrigerant gas to the compression space S1 or closes the suction port 12 of the piston 10 to block the refrigerant gas flowing into the compression space S1. .
이때, 흡입밸브(20)는 가스의 압력에 의해서 뿐만이 아니라 그 흡입밸브(20)의 자체 관성력에 의해서도 개폐하므로 흡입행정시에는 흡입저항을 줄이고 토출행정시에는 토출저항을 줄여 왕복동식 모터의 입력 대비 효율을 높일 수 있는 것이었다.At this time, the intake valve 20 is opened and closed not only by the pressure of the gas but also by the inertial force of the intake valve 20, so that the suction resistance is reduced during the suction stroke and the discharge resistance is reduced during the discharge stroke, compared to the input of the reciprocating motor. It was possible to increase the efficiency.
그러나, 상기와 같은 종래 압축용 흡입밸브 조립체는, 그 흡입밸브(20)를 지지하는 지지중심(b)과 흡입밸브(20)의 무게중심(a) 사이의 거리가 길어 특히 횡방향 설치시 흡입밸브(20)의 실링부가 처지면서 실링면(21a)이 마모하거나 지지축부(22)와 체결한 체결너트(30)가 반복피로 하중에 의해 파손할 우려가 있었다.However, the conventional compression suction valve assembly as described above has a long distance between the support center (b) for supporting the suction valve (20) and the center of gravity (a) of the suction valve (20). As the sealing portion of the valve 20 sag, the sealing surface 21a may be worn or the fastening nut 30 fastened to the support shaft 22 may be damaged by repeated fatigue load.
본 발명은 상기와 같은 종래 압축용 흡입밸브 조립체가 가지는 문제점을 감안하여 안출한 것으로, 흡입밸브의 지지부와 무게중심과의 거리를 줄여 밸브의 처짐을 줄이고 이를 통해 밸브의 실링면 마모를 줄여 밸브 효율을 향상함과 아울러 흡입밸브와 피스톤의 연결부 파손을 줄일 수 있는 압축용 흡입밸브 조립체를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional compression intake valve assembly as described above, reducing the deflection of the valve by reducing the distance between the support portion and the center of gravity of the suction valve, thereby reducing the valve surface wear valve efficiency It is an object of the present invention to provide a compression intake valve assembly that can reduce the damage to the connection between the suction valve and the piston as well as to improve the.

이에 도시한 바와 같은 본 발명의 압축용 흡입밸브 조립체는, 왕복동식 모터(미도시)의 가동자에 결합하여 실린더(도 1에 도시)(1)의 내부에서 왕복운동을 하면서 냉매가스를 흡입 압축하는 피스톤(100)과, 피스톤(100)에 끼워져 흡입유로(110)를 개폐하는 흡입밸브(200)로 구성한다.The compression intake valve assembly of the present invention as shown in the drawing, coupled to the mover of the reciprocating motor (not shown) and suction compression of the refrigerant gas while reciprocating inside the cylinder (shown in Figure 1) (1). And a suction valve 200 which is fitted to the piston 100 and the piston 100 to open and close the suction flow path 110.
피스톤(100)은 축방향으로 관통하는 흡입유로(110)를 형성하고, 흡입유로(110)의 출구측 끝단에는 흡입밸브(200)에 의해 개폐하는 흡입통구(120)를 형성하며, 흡입통구(120)의 안쪽에는 흡입밸브(200)를 연결하기 위한 고정돌부(130)를 형성한다.The piston 100 forms an intake passage 110 penetrating in the axial direction, and forms an intake passage 120 that is opened and closed by an intake valve 200 at an outlet end of the intake passage 110. Inside the 120 is formed a fixing protrusion 130 for connecting the intake valve 200.
흡입통구(120)는 흡입밸브(200)의 외주면과 함께 실링면(121)을 이루는 내주면이 바깥쪽으로 갈수록 확대하는 테이퍼진 단면으로 형성한다.The inlet port 120 is formed with a tapered cross section in which the inner circumferential surface constituting the sealing surface 121 together with the outer circumferential surface of the suction valve 200 enlarges toward the outside.
고정돌부(130)는 그 흡입유로(110)의 주면에서 중앙으로 연장 형성하는 지지몸체(131)와, 지지몸체(131)의 바깥단에 단차지게 확장 형성하여 흡입밸브(200)를 걸어 연결하는 지지돌기(132)로 이루어진다.The fixing protrusion 130 extends from the main surface of the suction flow path 110 to the center to form a support body 131 and a stepped extension to the outer end of the support body 131 to connect the intake valve 200 by walking. It consists of a support protrusion (132).
지지몸체(131)는 흡입유로(110)를 통과하는 유체가 흡입통구(120)까지 원활하게 유동할 수 있도록 정면투영시 양측에 흡입유로(110)와 연통하도록 가스유로를 구비한 형성하거나 또는 가스통공을 구비한 판형으로 형성하고, 지지돌기(132)는 직경이 서로 다른 원판을 부분적으로 중첩하여 정면투영시 "8"자 모양으로 확장부(132a)를 형성한다.The support body 131 is formed or provided with a gas passage so as to communicate with the suction passage 110 on both sides during the front projection so that the fluid passing through the suction passage 110 can flow smoothly to the suction passage 120 It is formed in a plate shape having a ball, the support protrusion 132 partially overlaps the disks of different diameters to form an extension 132a in the shape of an "8" in front projection.
한편, 흡입밸브(200)는 그 외주면이 흡입통구(120)의 내주면과 함께 면접촉하여 실링면(210)을 형성하도록 측면투영시 테이퍼진 단면 형상으로 형성하고, 피스톤(100)의 고정돌부(130)와 연결하는 압축배면의 중앙부에는 상기한 고정돌부(130)의 지지돌기(132)에 상응하도록 역시 직경이 서로 다른 구멍을 부분적으로 중첩하여서 된 관통구(221)를 갖는 걸림돌부(220)를 형성하며, 걸림돌부(220)의 안쪽에는 고정돌부(130)의 지지돌기(132)가 피스톤 방향으로 움직일 수 있도록 왕복공간부(230)를 형성한다.On the other hand, the suction valve 200 is formed in a tapered cross-sectional shape during the side projection so that the outer peripheral surface is in surface contact with the inner peripheral surface of the suction port 120 to form a sealing surface 210, the fixed protrusion ( A locking protrusion 220 having a through hole 221 partially overlapping holes having different diameters so as to correspond to the supporting protrusion 132 of the fixing protrusion 130 at the center portion of the compression back connecting to the 130. To form, and the inside of the locking protrusion 220 to form a reciprocating space 230 so that the support protrusion 132 of the fixing protrusion 130 can move in the piston direction.
여기서, 피스톤(100)의 실링면(121)과 흡입밸브(200)의 실링면(210)은 그 경사각은 고정돌부(130)의 선단면과 이에 대응하는 왕복공간부(230)의 내측면이 항상 이격상태를 유지할 수 있는 각도로 형성하는 것이 소음측면에서 바람직하다.Here, the inclined angle of the sealing surface 121 of the piston 100 and the sealing surface 210 of the suction valve 200 is the front end surface of the fixing protrusion 130 and the inner surface of the reciprocating space portion 230 corresponding thereto. It is preferable to form at an angle capable of maintaining a space at all times in terms of noise.
상기와 같은 본 발명 압축용 흡입밸브 조립체는 다음과 같이 조립한다.The compression suction valve assembly of the present invention as described above is assembled as follows.
즉, 흡입밸브(200)의 압력배면이 피스톤(100)의 흡입유로(110) 안쪽을 향하도록 한 상태에서 피스톤(100)의 고정돌부(132)를 흡입밸브(200)의 걸림돌부(220)에 삽입하여 고정한다.That is, in the state in which the pressure back surface of the suction valve 200 faces the suction flow path 110 of the piston 100, the locking protrusion 220 of the suction valve 200 is fixed to the fixing protrusion 132 of the piston 100. Insert into and fix it.
이때, 고정돌부(132)의 끝단에는 직경이 서로 다른 두 개의 원형 확장부(132a)를 부분적으로 중첩하도록 하여 지지돌기(132)를 형성하는 반면 이에 대응하는 걸림돌부(220)에도 직경이 서로 다른 두 개의 구멍을 부분적으로 중첩하여 관통구(221)를 형성함으로써, 도 7에서와 같이 고정돌부(132)의 지지돌기(132)를 걸림돌부(220)의 관통구(221)에 끼울 때 확장부(132a)와 관통구(221)의 형상과 크기가 대등한 방향으로 삽입한 후에 흡입밸브(200)를 약 90°정도 회전하면 지지돌기(132)의 확장부가 흡입밸브의 걸림돌부(220)에 걸쳐져 흡입밸브(200)가 피스톤(100)에 고정되어 연결된다.At this time, the support protrusion 132 is formed by partially overlapping the two circular expansion portions 132a having different diameters at the ends of the fixing protrusions 132, while the diameters of the locking protrusions 220 corresponding thereto are different from each other. By partially overlapping the two holes to form a through hole 221, as shown in Fig. 7 when the support protrusion 132 of the fixing protrusion 132 is fitted into the through hole 221 of the locking protrusion 220 When the suction valve 200 is rotated by about 90 ° after inserting the shape and size of the through hole 221 in the same direction, the extension of the support protrusion 132 is connected to the engaging protrusion 220 of the suction valve. The suction valve 200 is fixed to and connected to the piston 100.
이렇게 하여, 피스톤이 왕복동식 모터의 가동자와 함께 직선으로 왕복운동을 하면, 도 8 및 도 9에서와 같이 흡입밸브(200)는 자체 관성과 압력면 및 압력배면에 걸리는 압력차에 의해 피스톤(100)의 운동방향과 반대방향으로 동작하면서 피스톤(100)의 흡입통구(120)를 개폐하게 된다.In this way, when the piston reciprocates linearly with the mover of the reciprocating motor, as shown in Figs. 8 and 9, the suction valve 200 has a piston ( The suction port 120 of the piston 100 is opened and closed while operating in a direction opposite to the movement direction of 100.
이때, 흡입밸브(200)의 무게중심(a)과 그 흡입밸브(200)를 피스톤(100)에 고정하는 고정부 중심(b)을 서로 인접한 위치에 형성함에 따라 밸브의 개폐시 흡입밸브(200)의 거동이 안정되고, 피스톤(100)의 실링면(121)과 흡입밸브(200)의 실링면(210)이 원활하게 미끄러지면서 면접촉하여 마모를 줄일 수 있으며, 일정한 두께와 강도를 갖는 고정돌부(130)로 흡입밸브(200)를 고정함에 따라 고정돌부의피로한계를 높여 피스톤의 파손을 줄일 수 있다. 1은 실린더, 2는 토출밸브 조립체, 2A는 밸브하우징, 2B는 토출밸브, 2C는 밸브스프링, S1은 압축공간, S2는 토출공간이다.At this time, the center of gravity (a) of the intake valve 200 and the fixing center (b) for fixing the intake valve 200 to the piston 100 in the adjacent position to form the intake valve 200 when opening and closing the valve Stable behavior, the sealing surface 121 of the piston 100 and the sealing surface 210 of the intake valve 200 can slide smoothly to reduce the wear by the surface contact, fixed with a constant thickness and strength As the suction valve 200 is fixed to the protrusion 130, the fatigue limit of the fixing protrusion may be increased to reduce damage to the piston. 1 is a cylinder, 2 is a discharge valve assembly, 2A is a valve housing, 2B is a discharge valve, 2C is a valve spring, S1 is a compression space, and S2 is a discharge space.
발명에 의한 압축용 흡입밸브 조립체는, 피스톤에 고정돌부를 일체로 형성하여 그 고정돌부에 흡입밸브를 내부에서 끼워 연결함으로써, 흡입밸브의 무게중심과 고정부 중심을 인접한 위치에 형성하여 흡입밸브의 개폐동작시 거동을 안정화함과 아울러 실링면의 마모를 미연에 방지할 수 있고, 고정돌부의 피로한계를 높여 고정부의 파손을 크게 줄일 수 있다.In the compression suction valve assembly according to the present invention, the fixed protrusion is integrally formed on the piston, and the suction valve is connected to the fixed protrusion in the interior thereof, thereby forming the center of gravity of the suction valve and the center of the fixed portion in an adjacent position. In addition to stabilizing behavior during opening and closing operation, it is possible to prevent the wear of the sealing surface in advance, and to increase the fatigue limit of the fixing protrusion, thereby greatly reducing the damage of the fixing portion.
