이와같은 종래의 압축기구부는 전원이 인가되어 모터(A)가 회전하게 됨에 따라 크랭크축(4)이 회전하게 되고 크랭크축(4)의 회전력은 슬라이드(6)를 통하여 피스톤(11)으로 전달되어 실린더(10)내에서 피스톤(11)이 왕복직선 운동을 하게되는 바, 실린더(10)내의 피스톤(11)이 상사점에서 하사점으로 이동하는 경우 실린더(10) 내부의압력이 저하됨에 의하여 흡입밸브(13)가 열리게 되고 이와 동시에 유입관(도시하지 않음)을 통해 흡입싸이렌서(15)의 흡입실(15a)로 유입되는 냉매가스는 헤드커버(12)의 흡입구(12a)를 통해 실린더(10)내로 흡입되며, 이때 상기 피스톤(11)이 하사점에서 상사점으로 이동하게 되면 흡입밸브(13)는 닫히게 되어 냉매가스의 흡입이 차단되면서 실린더(10)내의 냉매가스는 압축되며, 이후 일정한 압력에 도달되면 냉매가스는 토출구(12b)에 설치된 토출밸브(14)를 밀어올리면서 토출실(16)로 토출되게 되는 흡입토출 과정이 반복되게 되는 것이다.Such a conventional compression mechanism is powered by the power of the motor (A) is rotated as the crankshaft 4 is rotated and the rotational force of the crankshaft (4) is transmitted to the piston (11) through the slide (6) When the piston 11 moves reciprocally linearly in the cylinder 10, when the piston 11 in the cylinder 10 moves from the top dead center to the bottom dead center, the pressure inside the cylinder 10 is lowered and the suction is performed. The valve 13 is opened and at the same time the refrigerant gas flowing into the suction chamber 15a of the suction silencer 15 through an inlet pipe (not shown) is connected to the cylinder through the suction port 12a of the head cover 12. 10) When the piston 11 is moved from the bottom dead center to the top dead center, the suction valve 13 is closed to block the refrigerant gas while the refrigerant gas in the cylinder 10 is compressed, and then the constant When the pressure is reached, the refrigerant gas is placed in the discharge port 12b. The suction discharge process to be discharged to the discharge chamber 16 while the discharge valve 14 is pushed up is repeated.
이와같이 된 종래의 흡입부구조는 실린더(10)내에서 피스톤(11)이 하강됨에 따라 실린더(10)내부의 압력이 저하되면서 흡입밸브(13)가 열리게 되어 냉매가스가 헤드커버(12)의 흡입구(12a)를 통해 실린더(10) 내부로 흡입되는 과정에 있어서, 통상적으로 온도를 떨어뜨리기 위하여 플라스틱제 흡입싸이렌서(15)를 거쳐 들어오게 되는 냉매가스는 고온의 헤드커버(12)와 접촉하게 되면서 실린더(10)내로 흡입되기 직전에 온도가 상승되어 비체적이 증가되므로 흡입효율이 떨어지게 되는 문제점이 있었으며, 또한 강재의 헤드커버(12)에 설치된 흡입밸브(13)가 폐쇄시 헤드커버(12)와 접촉되어 소음이 발생되는 등 전동압축기의 전체 효율이 저하되는 문제점이 있었다.In the conventional suction unit structure, the suction valve 13 is opened while the pressure in the cylinder 10 is lowered as the piston 11 is lowered in the cylinder 10, so that the refrigerant gas is suction port of the head cover 12. In the process of being sucked into the cylinder 10 through the 12a, the refrigerant gas, which is normally introduced through the plastic suction silencer 15 to lower the temperature, is brought into contact with the hot head cover 12. As the temperature is increased just before being sucked into the cylinder 10, the specific volume increases, so that the suction efficiency is lowered.
