The rolling plate generates the up / down rocking motion in the inclined state by the inclination angle of the rolling plate. It is a structure which forms a vacuum repeatedly.

다이어프램식 진공펌프에 있어서, 모터(1)의 회전중심에서 반경방향으로 일정거리를 이격하여 회전중심을 공전하는 경사핀(13)과, 경사핀과 결합되어 편심된 상·하 요동운동을 하는 롤링플레이트(9)와, 롤링플레이트와 결합되며 다이어프램가이드(3)와 에어포트(4) 사이에 위치한 3포인트 다이어프램(10)의 내부체적변화로 흡기와 배기동작을 반복하면서 진공펌핑이 가능하게 구성과;In the diaphragm type vacuum pump, the inclined pin 13 revolves around the center of rotation by radially spaced distance from the center of rotation of the motor 1, and the rolling in combination with the inclined pin for eccentric up / down rocking motion. Composed of a plate 9 and a rolling plate, the internal volume of the three-point diaphragm 10 located between the diaphragm guide 3 and the air port 4 allows vacuum pumping while repeating the intake and exhaust operations. ;

상기에 있어서, 롤링플레이트(9)의 요동중심에는 다이어프램가이드(3)의 중심부에서 돌출된 보스(20)가 접촉하는 구성과, 3포인트 다이어프램(10)의 외주는 에어포트(4)에 삽입고정되는 가이드링(12)에 의하여 다이어프램가이드(3)의 벽면에 밀착고정되게 한 것을 특징으로 하는 다이어프램식 진공펌프가 있었다.In the above, the configuration in which the boss 20 protruding from the center of the diaphragm guide 3 is in contact with the swinging center of the rolling plate 9, and the outer circumference of the three-point diaphragm 10 is inserted and fixed to the air port 4. There was a diaphragm type vacuum pump characterized in that the guide ring 12 is fixed to the wall surface of the diaphragm guide (3).
