A vane 9 for dividing the compression chamber 15 on the high pressure side and the suction chamber 14 on the low pressure side formed along the outer circumferential surface of the roller 8 which rotates and rotates by the spring 10, and the cylinder ( 7) accumulator 17 installed to prevent liquid refrigerant from flowing into the chamber, and L extending into the accumulator 17; -The suction stroke is started when the vane 9 is in the top dead center position of the refrigerant gas introduced into the inlet 12 of the cylinder 7 through the tube 18, so that the crankshaft 4 and the roller 8 It is composed of a discharge port 13 and a discharge valve (not shown) which is gradually compressed by the rotary motion to discharge the refrigerant gas of high temperature and high pressure.

상기 어큐뮤레이터(17)는 도 2 와 같이 용적을 결정하는 상부캡(19), 하부캡(20),바디(21)로 외형이 구성되고, 본체안으로 유입되는 냉매가스에 포함된 이물질의 유입을 방지하는 필터역활의 스크린 필터(22)가 장착되며, 냉매가스가 직접 압축기로 유입되지 못하게 냉매가스의 흐름방향을 조절하는 돌출부(23b)가 형성된 스크린 홀더(23)를 스크린 필터(22)뒤에 장착한다.The accumulator 17 is configured as the upper cap 19, the lower cap 20, the body 21 to determine the volume as shown in Figure 2, the inflow of foreign matter contained in the refrigerant gas flowing into the body The screen filter 22 of the filter role to prevent the filter is mounted, and behind the screen filter 22 is a screen holder 23 having a projection 23b for adjusting the flow direction of the refrigerant gas so that the refrigerant gas does not directly flow into the compressor. Mount it.

상기 상부파이프(24)로부터 유입된 액냉매가 직접 L-튜브(18)로 유입되는 것을 방지하도록 L-튜브(18)의 동심원밖에 냉매유입구(23a)를 두고 있다.The refrigerant inlet 23a is provided outside the concentric circle of the L-tube 18 to prevent the liquid refrigerant introduced from the upper pipe 24 directly into the L-tube 18.

상기 L-튜브(18)는 유입된 냉매가스를 압축기로 유입시키도록 상기 스크린 홀더(23)의 하부에서 바디(21)에 지지되는 튜브 홀더(25)를 장착하여 고정되며, 상기 튜브 홀더(25)는 실린더(7)관내부로 진동 및 소음이 전달되는 것을 방지한다.The L-tube 18 is fixed by mounting a tube holder 25 supported on the body 21 at the bottom of the screen holder 23 to introduce the refrigerant gas introduced into the compressor, the tube holder 25 ) Prevents the transmission of vibration and noise into the cylinder (7) tube.

또한, 상기 실린더(7)에서 토출되어 어큐뮤레이터(17)로 유입된 오일이 냉매가스와 같이 L-튜브(18)를 통해 실린더(7)로 다시 유입될수 있게 L-튜브(18)의 소정위치에는 오일 유입을 위한 오일홀(26)이 있다.In addition, the oil discharged from the cylinder 7 and introduced into the accumulator 17 may be introduced into the cylinder 7 through the L-tube 18 like the refrigerant gas. At the location there is an oil hole 26 for oil inlet.

상기 어큐뮤레이터(17)는 액냉매 유입방지 및 리시버 역할, 그리고 하나의 공명기 역할을 한다.The accumulator 17 serves as a liquid refrigerant inflow prevention and receiver, and serves as a resonator.

그리고, 도 3 의 (가)(나)에 도시한 바와같이 상기 어큐뮤레이터(17)의 상부파이프(24)로부터 유입되는 냉매가스는 압력강하가 크기 때문에 이 압력이 상기 스크린 홀더의 돌출부와 충돌하여 마찰을 일으켜 압력손실이 상당량 발생하게 된다.As the refrigerant gas flowing from the upper pipe 24 of the accumulator 17 has a large pressure drop, the pressure collides with the protrusion of the screen holder. As a result, a large amount of pressure loss occurs.

이 때, 상기 액냉매가 유입될 경우 직접 L-튜브(18)로 유입되지 않도록 L-튜브(18)의 동심원밖에 형성이 된 냉매유입구(23a)을 통해 유입된 액냉매는 상기 어큐뮤레이터(17)의 하부로 낙하하고, 증발된 냉매가스만이 L-튜브(18)의 끝단유입구로 들어오게 된다.At this time, the liquid refrigerant flowing through the refrigerant inlet 23a formed outside the concentric circle of the L-tube 18 so that the liquid refrigerant is not directly introduced into the L-tube 18 is the accumulator ( Falling to the bottom of 17, only the vaporized refrigerant gas enters the end inlet of the L-tube (18).

그리고, 상기 냉매가스는 이물질이 유입되지 않도록 상기 스크린 필터(22)를 통하여 유입된다.In addition, the refrigerant gas is introduced through the screen filter 22 to prevent foreign substances from entering.

그러나, 이러한 종래의 어큐뮤레이터는 냉매가스 흡입시 스크린 홀더의 마찰이 증가하여 흡입손실이 발생하므로 압축기의 성능이 저하되는 문제점이 있다.However, such a conventional accumulator has a problem in that the performance of the compressor is deteriorated because the suction of the refrigerant is increased by the friction of the screen holder.

본 발명은 이러한 종래 문제점을 감안하여 발명된 것으로 상부파이프로부터 유도되는 냉매가스가 직접압축기로 유입되지 못하게 냉매가스의 흐름방향을 조절하는 돌출부가 형성된 스크린 홀더에 있어서, 상기 돌출부의 선단은 넓게 형성하고, 아래로 갈수록 좁아지게 형성하여 측면에서의 마찰 없이 냉매유입구로 냉매가스를 유도함으로써, 흡입가스의 돌출부 측면에서의 마찰을 저감시켜 압축기 성능을 향상시키도록 한 것이다.The present invention has been invented in view of such a conventional problem, and in the screen holder formed with a protrusion for adjusting the flow direction of the refrigerant gas so that the refrigerant gas derived from the upper pipe does not flow into the direct compressor, the tip of the protrusion is formed wide In order to improve the performance of the compressor by reducing the friction on the side of the protrusion of the suction gas by inducing the refrigerant gas to the refrigerant inlet without friction on the side by forming narrower toward the bottom.

본 발명 압축기용 어큐뮤레이터 작동상태를 도 4 내지 도 7 에 의거하여 설명하면,Referring to the accumulator operating state of the present invention compressor based on Figures 4 to 7,

먼저 도 4 와같이 상기 어큐뮤레이터(101)내에는 상기 상부파이프(109)로부터 유도되는 냉매가스가 직접압축기로 유입되지 못하게 냉매가스의 흐름방향을 조절하는 돌출부(111)가 형성된 스크린 홀더(107)를 구성한다.First, as shown in FIG. 4, the accumulator 101 includes a screen holder 107 having a protrusion 111 for adjusting the flow direction of the refrigerant gas so that the refrigerant gas derived from the upper pipe 109 does not flow into the direct compressor. ).

그리고, 액냉매의 직접적인 유입을 방지할 목적과 이물질의 유입을 방지하는 스크린 필터(106)의 고정을 목적으로 사용되는 스크린 홀더(107)에는 액냉매의 유입이 원할하도록 충분한 유로 면적이 확보된 냉매유입구(107a)을 통해 압력 맥동효과를 극대화 한다.In addition, the screen holder 107 used for the purpose of preventing the direct inflow of the liquid refrigerant and for fixing the screen filter 106 to prevent the inflow of foreign matters has a refrigerant having a sufficient flow path area for the inflow of the liquid refrigerant. Through the inlet 107a to maximize the pressure pulsation effect.

이 때 도 5 의 (가)(나)에 도시한 바와같이 상기 상부파이프(109)로부터 유도되는 냉매가스의 유입속도가 상당히 강하므로 상기 스크린 홀더(107)의 중심부와 흡입가스가 마찰이 생기기 된다.At this time, as shown in (a) of (b) of FIG. 5, since the inflow velocity of the refrigerant gas derived from the upper pipe 109 is very strong, the center portion of the screen holder 107 and the suction gas generate friction. .

이 마찰에 의해 압력손실이 상당량 발생하게 되므로 마찰을 줄이기 위해 상기 돌출부(111)의 선단은 넓게 형성하고, 아래로 갈수록 좁아지게 형성하여 상기 냉매유입구(107a)로 냉매가스를 측면과의 마찰을 줄이면서 유도할수 있다.Due to this friction, a considerable amount of pressure loss is generated, so that the tip of the protrusion 111 is formed wider and narrowed downward to reduce friction, thereby reducing the friction of the refrigerant gas with the side surface of the refrigerant inlet 107a. While it can be derived.

그리고, 스크린 홀더(107)의 다른실시예를 보면, 도 6 의 (가)(나)에 도시한 바와같이 상기 스크린 홀더(107)의 돌출부(111)의 형상을 갓형상으로 형성하고, 또한 도 7 의 (가)(나)와 같이 상기 스크린 홀더의 돌출부 형상을 캡형상으로 형성하여 냉매가스의 마찰을 저감시켜 압력손실을 감소시킬수 있다.And, in another embodiment of the screen holder 107, as shown in (a) (b) of FIG. 6, the shape of the protrusion 111 of the screen holder 107 is formed in the shape of a lampshade, and also shown in FIG. As shown in (a) of (7), the protrusion of the screen holder may be formed in a cap shape to reduce the friction of refrigerant gas, thereby reducing the pressure loss.

본 발명의 효과는 흡입된 냉매가스의 압력강하에 따른 마찰이 현저히 줄어들어 흡입측의 손실이 감소함으로써, 압축기의 성능을 향상시킨다.The effect of the present invention is that the friction caused by the pressure drop of the refrigerant gas is significantly reduced and the loss on the suction side is reduced, thereby improving the performance of the compressor.
