상기와 같은 밸브유니트(60)는 밸브 플레이트(61)에 형성된 셋팅 핀(61c)에 상기 토출리드밸브(62) 및 흡입리드밸브(63)가 각각 결합됨으로서 그 위치가 셋팅되는 것이다.In the valve unit 60 as described above, the discharge lead valve 62 and the suction lead valve 63 are respectively coupled to the setting pin 61c formed in the valve plate 61, and thus the position thereof is set.

한편, 상기 전,후방 실린더블록(20)(20a) 사이의 사판실(24)로 공급된 냉매가 상기 각 흡입실(11)로 유동할 수 있도록 상기 전,후방 실린더블록(20)(20a)에는 다수의 흡입통로(22)가 형성되며, 상기 전,후방 하우징(10)(10a)의 토출실(12)은 상기 전,후방 실린더블록(20)(20a)에 형성된 연결통로(23)에 의해 상호 연통된다.Meanwhile, the front and rear cylinder blocks 20 and 20a may allow the refrigerant supplied to the swash plate chamber 24 between the front and rear cylinder blocks 20 and 20a to flow into the suction chambers 11. A plurality of suction passages 22 are formed therein, and the discharge chambers 12 of the front and rear housings 10 and 10a are connected to the connection passages 23 formed in the front and rear cylinder blocks 20 and 20a.

따라서, 상기 피스톤(50)의 왕복운동에 따라 상기 전,후방 실린더블록(20)(20a)의 실린더보어(21)내에서 동시에 냉매의 흡입 및 압축이 수행될 수 있는 것이다.Therefore, the suction and compression of the refrigerant may be simultaneously performed in the cylinder bore 21 of the front and rear cylinder blocks 20 and 20a according to the reciprocating motion of the piston 50.

그리고, 상기 전,후방 실린더블록(20)(20a)의 중앙에는 구동축(30)을 지지할 수 있도록 지지공(25)이 형성되고, 상기 지지공(25) 내에는 니들롤러베어링(26)이 개재되어 상기 구동축(30)을 회전가능하게 지지하고 있다.In addition, a support hole 25 is formed in the center of the front and rear cylinder blocks 20 and 20a to support the drive shaft 30, and a needle roller bearing 26 is formed in the support hole 25. It interposes and supports the said drive shaft 30 rotatably.

한편, 상기 후방 하우징(10a)의 외주면 상부에는 피스톤(50)의 흡입행정시 증발기로부터 이송된 냉매를 압축기(1) 내부로 공급하고, 피스톤(50)의 압축행정시 에는 압축기(1) 내부에서 압축된 냉매를 응축기 쪽으로 토출하도록 머플러(70)가 설치된다.On the other hand, in the upper part of the outer peripheral surface of the rear housing (10a) the refrigerant conveyed from the evaporator during the suction stroke of the piston 50 is supplied into the compressor (1), and during the compression stroke of the piston 50 in the compressor (1) The muffler 70 is installed to discharge the compressed refrigerant toward the condenser.

상기 머플러(70)에는 흡입머플러실(73)과 토출머플러실(74)이 구획되어 형성되며, 상측에는 상기 흡입머플러실(73)과 토출머플러실(74)을 밀폐하도록 별도의 커버(75)가 결합되어 증발기 및 응축기와 파이프로 연결된다.The muffler 70 is formed by partitioning the suction muffler chamber 73 and the discharge muffler chamber 74, and a separate cover 75 to seal the suction muffler chamber 73 and the discharge muffler chamber 74 on the upper side.
