A cam type door closer comprises a main body, a first piston assembly, a second piston assembly, and a power transmission shaft assembly. The main body includes an axial passage and a longitudinal passage which are in communication with and perpendicular to each other. The first piston assembly is held and installed at one side of the axial passage, and the second piston assembly is held and installed at the other side of the axial passage of the main body. The second piston assembly includes a second piston, a gap compensation device, a second spring and a second sealing cap. The second piston is movably mounted in the shaft hole of the first piston, the gap compensation device is mounted within the second piston, the second spring has one end installed in contact with the second piston and the other end in contact with the second sealing cap, and the second sealing cap is installed in the main body to seal the axial passage. The power transmission shaft assembly penetrates into the longitudinal passage to be able to rotate, and includes a shaft lever and an eccentric cam. The eccentric cam is located on the shaft lever with one side thereof in contact with the roller and the other side in contact with the second piston. The present invention can control the closing speed of the glass door in the whole process, and has the advantage of positioning the glass door at a predetermined pivot angle.
캠타입 도어클로저에 있어서, 본체, 제1 피스톤 어셈블리, 제2 피스톤 어셈블리 및 전동축 어셈블리를 포함하는 것으로, 본체에는 서로 연통되어 수직되는 축방향 통로 및 종방향 통로가 설치되고, 제1 피스톤 어셈블리는 축방향 통로의 일측에 수용되어 설치되고, 제2 피스톤 어셈블리는 본체의 축방향 통로의 타측에 수용되어 설치되며, 제2 피스톤 어셈블리는 제2 피스톤, 간격 보상 장치, 제2 스프링 및 제2 밀봉 캡을 구비하는 것으로, 제2 피스톤은 이동 가능하게 제1 피스톤의 축홀에 설치되고, 간격 보상 장치는 제2 피스톤 내부에 설치되며, 제2 스프링의 일단은 제2 피스톤에 맞닿게 설치되고 타단은 제2 밀봉캡에 접촉되며, 제2 밀봉캡은 본체에 설치되어 축방향 통로를 밀봉하고, 전동축 어셈블리는 회동 가능하게 종방향 통로를 관통하되, 축 레버 및 편심 캠을 구비하며, 편심 캠은 축 레버에 설치되되 일측은 로울러에 접촉되고, 타측은 제2 피스톤에 접촉된다.
