Abstract
Description
Claims (1)
- 공압실린더(2)의 피스턴(1) 양측에 배치되는 슬라이드링(10)과, 피스턴(1) 몸체의 외주면 중간부에 형성된 압력실(1a)의 외축에 신축 가능하게 설치되는 시일링(11)을 구비하고, 상기 압력실(1a) 내부에 작용되는 압축공기에 의해 시일링(11)을 팽창시켜 피스턴(1)의 제동 및 밀폐가 이루어질 수 있게한 공압실린더의 피스턴 시일장치에 있어서, 상기 피스턴(1)몸체의 압력실(1a)과 피스턴(1) 의 양단간에 설치된 공압관로(14-1), (14-2)상에 전기적 신호에 의해 제어되는 소형 솔레노이드밸브(12-1), (12-2)를 각각 내장하여 그 각 솔레노이드밸브(12-1), (12-2)를 통해 작용되는 실린더(2) 내부의 피스턴 구동압력(P1), (P2)으로 시일링(11)을 작동시킬수 있게 구성함을 특징으로 하는 공압실린더의 피스턴 시일장치.
