Description

유압실린더의 쿠션장치Cushion device of hydraulic cylinder

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도, 제2도 및 제3도는 본 발명의 실시예의 요부의 확대종단(擴大終端) 정면도로서, 제1도 및 제2도는 실린더 헤드축에 쿠션기구를 구성한 것이며, 제1도는 쿠션행정의 종료기, 제2도는 작동시동행정의 초기, 제3도는 실린더보텀측에 쿠션기구를 구성한 것으로서 쿠션행정의 종료기를 가리킨다.1, 2 and 3 are enlarged end front views of main parts of an embodiment of the present invention, in which FIGS. 1 and 2 constitute a cushioning mechanism in a cylinder head shaft, and FIG. Fig. 2 shows the initial stage of the starting operation stroke, and Fig. 3 shows the end of the cushion stroke as a cushion mechanism is formed on the cylinder bottom side.

Claims (1)

피스톤에 인접한 피스톤로드에 소경부를 설치하고, 이 소경부에 쿠션링을 유동가능하게 끼우며, 이 쿠션링의 외주가 피스톤의 작동종단에 있어서 실린더보텀 또는 실린더헤드의 내주와의 사이에 쿠션조리개를 형성함과 동시에, 이 쿠션조리개가 작용하였을때 상기 피스톤 로드와 쿠션링과의 사이에 압력실측과 배출측과의 사이를 폐색하고, 피스톤의 작동시동행정에 있어서는 공급축과 압력실측을 접속하는 역지밸브기구를 구성하는 쿠션기구에 있어서, 상기 역지밸브비구를, 피스톤로드의 소경부에 연설한 단부와, 쿠션링의 내주에 설치하고, 상기 단부에 맞닿는 어깨부와 구성한 것을 특징으로 하는 유압실린더의 쿠션장치.A small diameter part is provided on the piston rod adjacent to the piston, and the cushioning ring is movably fitted to the small diameter part, and the cushion circumference of the cushion ring is disposed between the cylinder bottom or the inner circumference of the cylinder head at the end of operation of the piston. At the same time, when the cushion stopper acts, the piston rod is closed between the pressure chamber side and the discharge side between the piston rod and the cushioning ring. In the cushion mechanism constituting the valve mechanism, the hydraulic valve characterized in that the check valve is provided with the end portion extending to the small diameter portion of the piston rod and the shoulder portion provided on the inner circumference of the cushion ring and abuts the end portion. Cushion device. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
