피스톤으로전달하는크탱크식과,사판이설치된회전축으로전달하는사판식, 및워블플레이트를사용하는워블플레이트식이있고,회전식압축기에는 회전하는로터리축과베인을사용하는베인로터리식,및선회스크롤과고정 스크롤을사용하는스크롤식이 있다.
[5] 사판식압축기로는사판의설치각도가고정된고정용량형타입과,사판의 경사각을변화시켜토출용량을변화시킬수있는가변용량형타입이있다.
[6]
[7] 상기와같은다양한종류의압축기에서구동부에대한윤활은오일에의해 이루어지는데이러한오일은넁매와함께흔합되기때문에넁매의토출측에서 오일만을분리하여압축기의구동부로재공급하기위한오일분리기는 압축기의필수구성요소에해당한다.
[8] 종래의사판식압축기에설치된오일분리기는상기오일분리기를구비하는 하우징과,다수개의실린더보어가형성되며상기하우징에결합되는
실린더블록과,상기실린더블록에대하여회전가능하게설치되는구동축및 상기구동축에의해회전하도록설치되는사판을포함하여구성된다.
[9] 또한상기사판식압축기는토출넁매가유입되는오일분리실과,상기
오일분리실에설치되는오일분리기,및상기오일분리기에서넁매와분리된 오일을상기사판이설치된크탱크실로공급하는오일배출유로를포함하되, 상기오일분리실로오일이포함된토출넁매가유입되어원심력에의해 오일분리실내주면에오일이분리되어잔류하게되고,상기오일분리실 내주면에잔류된오일은상기오일배출유로를통해크탱크실로공급되는 구성적특징을가지고있다. [10] 이경우오일분리어셈블리는넁매중오일성분을분리하기위한 오일분리기를반드시구비해야하는데,이러한오일분리기는그길이에따라 오일을분리할수있는성능이결정되기때문에오일분리기의길이는최대한 길게확보하는것이바람직하다.
[11] 그러나상기와같은구조의종래사판식압축기는방사상으로배치되는다수의 실린더보어를형성하는실린더블록에대해오일분리어셈블리를함께 구비하고있기때문에오일분리기의길이를길게설정하는데많은제약을 수반하게된다.
[12] 예를들면,실린더블록의상부에오일분리어셈블리를설치할경우에는
실린더보어와의간섭을회피해야하기때문에오일분리기의길이는한정될수 밖에없고,이와달리오일분리기의길이를길게설정하게되면사판식압축기의 전체부피가과도하게증가하기때문에다른부품과의레이아웃상간섭을 유발하는등의문제를초래하게된다.
[13] 즉,종래사판식압축기는패키지에제약이있기때문에오일분리어셈블리의 구성에 있어오일분리기의길이를작게설정할수밖에없고,이로인해유분리의 성능이저하되어구동부에대한만족스러운윤할효과를기대할수없게된다.

발명의실시를위한최선의형태
[42] 본발명은다양한변경을가할수있고여러가지실시예를가질수있는바, 특정실시예들을도면에 예시하고상세하게설명하고자한다.그러나,이는본 발명을특정한실시형태에대해한정하려는것이아니며,본발명의사상및 기술범위에포함되는모든변경,균등물내지대체물을포함하는것으로 이해되어야한다.첨부된도면에도시된선들의두께나구성요소의크기등은 설명의명료성과편의를위해과장되게도시되어있을수있다.
[43] 또한,후술되는용어들은본발명에서의기능을고려하여정의된용어들로서 이는사용자,운용자의의도또는판례에따라달라질수있다.그러므로,이러한 용어들에대한정의는본명세서전반에걸친내용을토대로하여내려져야할 것이다.
[44]
[45] 이하,본발명에따른바람직한실시예를첨부된도면을참조하여상세하게 설명한다.참고로도 1은본발명의일실시 예에의한양두사판식압축기를 도시한단면도이고,도 2는본발명의일실시 예에의한양두사판식압축기를 도시한사시도이다.
[46] 첨부된도 1내지도 2를참조하면,본실시 예에의한양두사판식압축기 (1)는 실린더블록 (100)과,전방헤드 (210)와후방헤드 (230)로이루어진실린더 헤드 (200)와,오일분리부 (300)및오일저장부 (400)를포함하여구성된다.
[47] 실린더블록 (100)은양두사판식압축기의외형을이루는구성요소로써내부 중앙에샤프트 (2)가외부에서전달된구동력에의해회전가능하게설치되고, 상기샤프트 (2)의축방향에넁매의압축을위한사판 (s)이삽입된다.
[48] 실린더블록 (100)은내부에사판실이형성되는데,상기샤프트 (2)를감싸는 형태로배치되고원주방향으로다수개의실린더보어가배치되며,상기실린더 보어에피스톤 (3)이배치된다.상기피스톤 (3)은샤프트 (2)의회전상태에따라 상기실린더보어에서길이방향으로이동되면서넁매에대한압축을실시한다.
[49] 상기실린더블록 (100)은후술할실린더헤드 (200)의후방헤드 (230)에압축된 넁매를공급하기위해넁매이동유로 (4) (도 2참조)가형성되어있어압축된 넁매가이동되는데,상기넁매이동유로 (4)를통해피스톤 (3)의이동에따라 압축된넁매가안정적으로이동된다.
[50]
[51] 실린더헤드 (200)는상기실린더블록 (100)의전방에설치된전방헤드 (210)와, 상기실린더헤드 (200)의후방에설치되고내부에넁매가토출되는토출 챔버 (232)가형성된후방헤드 (230)를포함한다.
[52]
[53] 오일분리부 (300)는토출챔버 (232) (도 3참조)와이웃하여넁매유입구 (302)가 형성되고,상기후방헤드 (230)와일체로이루어져상기후방헤드 (230)의하측을 향해경사지게연장되며,후술할오일저장부 (400)에하단이연통된형태로 배치된다.
[54] 오일분리부 (300)는넁매에포함된오일을분리하기위해내부가중공의
원기등형태로형성되고,하단에위치된오일저장부 (400)로분리된오일이 이동되도록상기오일저장부 (400)의상면과연통된다.
[55] 오일분리부 (300)는넁매유입구 (302)가형성되는데,상기넁매유입구 (302)는 오일분리부 (300)의길이방향을기준으로중간상측에개구되고,상기넁매 유입구 (302)는넁매가토출챔버 (232)에서오일분리부 (300)의내측을향해 이동될때내측원주방향으로소정이속도로회전력이유지된상태로하측으로 이동되기위해상기위치에배치된다.
[56] 특히넁매는소정의압력으로상기넁매유입구 (302)에서오일분리부 (300)의 내부영역으로토출되는데,위치가오일분리부 (300)의중간상측에위치되어 있으므로상기오일분리부 (300)의하측길이방향으로이동되는동안내주면을 따라회전이동되는회전력이안정적으로유지되어넁매에포함된오일이 용이하게분리된다.
[57]
[58] 넁매유입구 (302)는오일분리부 (300)의측면위치에개구되는데,상기넁매 유입구 (302)의개구된방향은넁매가토출되는방향을오일분리부 (300)의 내측면을기준으로중앙이아닌측면으로이동되도록유도하여상기오일 분리부 (300)의길이방향을따라이동되는넁매에포함된오일을손쉽게 분리시킬수있다.
[59] 넁매유입구 (302)는상기오일분리부 (300)의내측을향해제 1경사각 (Θ1)을 갖고경사지게개구되는데,여기서제 1경사각 ((Θ1)은오일분리부 (300)의내측을 향해개구된넁매유입구 (302)가내측하부를향해경사지게배치된각도를 의미한다.
[60] 상기제 1경사각 (Θ1)은 5도이상 20도이하의경사각중어느하나의경사각에 해당되며이하첨부된표 1을참조하여설명한다.
Figure imgf000007_0001
[62] [표 1]
[63] 첨부된표 1을참조하면,제 1경사각 (Θ1)은양두사판식압축기가
800알피엠으로작동되고, Pd/Td가 19kgf/cm2G / 90°C, OIC 3%의조건에서실험을 실시하였고,상기넁매유입구 (302)의경사각은 0도에서부터 30도까지실험이 이루어졌다.
[64] 상기넁매유입구 (302)의제 1경사각 (Θ1)이 0도에서는넁매에포함된유분리 효율이 42.3%로측정되었고, 5도에서부터 20도이하에서는 50%이상의유분리 효율이유지되는것으로측정되었다.
[65] 특히제 1경사각 (θ 1)이 20도이상일경우넁매에포함된오일이오일
분리부 (300)의하부에서토출포트 (미도시)로이동되는현상이발생되어넁매에 포함된오일을분리하는데바람직하지않은것으로실험결과입증되었다.
[66] 이와는반대로넁매유입구 (302)의제 1경사각 (Θ1)이 5도또는 10도또는 15도 또는 20도중의어느하나의경사각으로형성될경우넁매에포함된오일의 유분리효율이안정적으로유지되는것을알수있다.
[67] 이와같이넁매에포함된오일의유분리효율이 50%이상유지될경우넁매의 압축성능이향상되고,피스톤 (3)의이동에따른오일이안정적으로공급될수 있어마찰로인한마모및열발생이최소화된다.
[68] 참고로상기제 1경사각 (Θ1)은 15도일경우유분리효율이가장우수하므로 상기넁매유입구 (302)의제 1경사각 (Θ1)은 15도의각도로개구되는것이 바람직하나전술한각도중의어느하나의각도로개구되는것도가능함을 밝혀둔다.
[69]
[70] 넁매유입구 (302)는 5mm이상 7mm이하의직경으로개구되는데,상기직경중
5mm이하로개구될경우직경축소로인해오일분리부 (300)의내부영역으로 토출되는속도가증가되어오일분리부 (300)의길이방향을따라이동속도가 증가될수있어넁매에포함된오일의분리효율이저하될수있다. [71] 이와는반대로상기넁매유입구 (302)가 7mm이상의직경으로형성될경우 상기오일분리부 (300)의내측으로분사되는속도는 5mm이하로개구될경우에 비해감소되나전술한직경의범위에서의유분리효율보다는상대적으로 감소되므로상기넁매유입구 (302)의직경은전술한 5mm이상 7mm이하의 직경으로개구되는것이가장바람직하다.
[72]
[73] 첨부된도 3내지도 4를참조하면,오일분리부 (300)는오일저장부 (400)와 연결되도록하단에상기오일저장부 (400)를향해직경이축소되는
경사부 (306)와,상기경사부 (306)에서상기오일저장부 (400)를향해일정 직경으로연장된연장부 (308)를포함한다.
[74] 상기경사부 (306)는도면에도시된바와같이길이방향하측으로갈수록
직경이감소되므로넁매에포함된오일이상기오일분리부 (300)의내주면을 따라이동된후에상기경사부 (306)에서중앙을향해오일이안정적으로모이게 된다.그리고연장부 (308)를통해오일저장부 (400)로오일이안정적으로이동될 수있다.
[75]
[76] 오일저장부 (400)는상기오일분리부 (300)의하단에위치되고상기오일
분리부 (300)에서분리된오일이저장되는공간을제공하는데,상기오일 저장부 (400)는일예로상기후방헤드 (230)의측면에서수평하게연장된다.
[77] 상기오일저장부 (400)는내부가중공상태로이루어져다량의오일이
저장되는공간을제공하며일예로내부영역이중공의실린더형태로 이루어지고길이방향일단부에상기오일저장부 (400)에서탈착가능하게 캡 (410)이설치된다.
[78] 상기오일저장부 (400)는후방헤드 (230)의직경과유사한길이로연장될수 있는데,이경우상기오일저장부 (400)가후방헤드 (230)의외측으로돌출되는 정도가최소화될수있어양두사판식압축기가차량에설치되는경우설치 장소의레이아웃에의한영향이최소화될수있다.
[79] 따라서넁매에포함된오일에대한저장을안정적으로실시하면서도양두 사판식압축기의설치에따른부피가최소화될수있으므로크기축소로인한 설치공간에대한활용성이향상된다.
[80] 오일저장부 (400)는수평하게배치되므로연장부 (308)를통해이동된오일은 유면이수평상태가유지되고,후술할오리피스 (20)를통해안정적으로 공급된다.
[81]
[82] 캡 (410)은오일저장부 (400)에대해탈착이용이하도록볼트형태로형성될수 있는데,이경우상기오일저장부 (400)의내측에는상기캡 (410)의손쉽운 결합을위해나사산이형성된다.따라서작업자는상기오일저장부 (400)에 캡 (410)을설치하기용이하고상기오일저장부 (400)의점검을위해주기적으로 캡 (410)을분리시켜내부상태를확인할수있으므로오일의침전또는이물질 누적에따라후술할오리피스 (20)로오일이항시일정하게공급될수있도록 유지관리할수있다.
[83] 오일분리부 (300)는상기오일저장부 (400)에대해 45이상의각도가유지되는 제 2경사각 ((Θ2)으로배치되는데,여기서제 2경사각 ((Θ2)은후방헤드 (230)에 대해경사지게배치된오일분리부 (300)와상기후방헤드 (230)의하측에 수평하게배치된오일저장부 (400)사이에형성된경사각을의미한다.
[84] 상기오일분리부 (300)의경사각도가 45도이상의각도로경사지게배치될 경우넁매가포함된오일이오일저장부 (400)를향해안정적으로이동될수 있으므로상기경사각도로배치되는것이양두사판식압축기의유분리효율을 향상시키는데효율적이다.
[85]
[86] 오일저장부 (400)와상기후방헤드 (230)사이에는상기오일저장부 (400)로 이동된오일이상기후방헤드 (230)로공급되기위한오일리턴홈 (10)이 형성되고,상기오일리턴홈 (10)에는오리피스 (20)가설치된다.
[87] 상기오일리턴홈 (10)은상기오일저장부 (400)의측면하측과연통되고
수평하게연장되므로전술한오일저장부 (400)에저장된오일은오리피스 (20)를 향해안정적으로오일이이동된다.따라서양두사판식압축기의작동에필요한 오일을안정적으로공급할수있어오일공급성이향상된다.
[88] 오일리턴홈 (10)은상기연장부 (308)가연장된연장선상에배치되므로상기 연장부 (308)를통해이동된오일은상기오일리턴홈 (10)을통해안정적으로 이동될수있고,상기오일이오일리턴홈 (10)으로이동되는이동경로가 최단거리로유지되므로경로단순화가동시에도모된다.
[89]
[90] 오리피스 (20)는사판실로이동되는오일량을일정하게하여피스톤 (3)의
안정적인작동을도모한다.오리피스 (20)는상기오일저장부 (400)의축방향과 수직으로직교된연장선상에배치되며,연장부 (308)를경유하여오일
저장부 (400)로이동된오일이상기오리피스 (20)에서연장된연장선상으로 낙하되므로오일리턴홈 (10)를경유하여오리피스 (20)를향해최단거리로 이동된다.
[91] 상기오리피스 (20)는상기오일리턴홈 (10)에삽입되고상기오리피스 (20)의 유입구 (미도시)와연통되므로오일이오리피스 (20)를경유하여안정적으로 이동된다.
[92]
[93] 본발명의다른실시 예에의한오일저장부에대해도면을참조하여설명한다.
[94] 첨부된도 5를참조하면,오일저장부 (400)는일측단부 (도면을기준으로
좌측)가상측을향해경사진제 3경사각 (Θ3)이유지된상태로배치될수있으며 , 상기제 3경사각 (Θ3)은후방헤드 (230)에대해경사지게배치된오일 분리부 (300)와상기후방헤드 (230)의하측에서도면기준좌측상부로경사지게 배치된오일저장부 (400)사이에형성된경사각을의미한다.
[95] 이와같이배치될경우상기오일분리부 (300)에서분리된오일은캡 (410)이 설치된반대쪽에해당되는오일리텀홈 (10)으로모이게되는데,이경우항시 오일이경사진오일저장부 (400)의하측에위치된상태가유지되므로상기오일 리턴홈 (10)을경유하여오리피스 (20)를향해안정적으로오일이공급될수있다.
[96] 따라서사판실로오일이리턴되지않고오일저장부 (400)에고여있는상태가 최소화될수있다.
[97] 상술한바와같이본발명은도면에도시된실시 예를참고로하여
설명되었으나,이는예시적인것에불과하며,당해기술이속하는분야에서 통상의지식을가진자라면이로부터다양한변형및균등한타실시예가 가능하다는점을이해할것이다.따라서본발명의진정한기술적보호범위는 아래의특허청구범위에의해서정하여져야할것이다.
