Abstract

내부 수평 조절장치가 장착된 자동펌프형 수·공압식(水·空壓式)의 차량용 완충 스프링은 완충매체로 채워져 고압실에 배열되어서 스프링 작용을 하는 가스쿠션의 압력을 받는 작동 실린더를 구비한다. 이 작동 실린더는 속이 비어있는 피스톤로드에 의하여 둘러싸이고 밸브가 구비된 작동 피스톤으로 인하여 두개의 작동실로 나뉜다. 또한 작동 실린더는 스프링 운동에 의해 작동되며, 기름을 저압실에서 고압실과 연결된 작동 공간으로 이동시키는 피스톤 펌프를 구비하고, 이 피스톤 펌프는 속이 비어 있는 피스톤로드에 의해 형성된 펌프실과 작동 실린더와 연결된 하나의 펌프로드로 구성된다. 이때 펌프실 안에 있는 완충매체는 추진 요소에 의해 압력을 받는다.The self-pumping, hydraulic and pneumatic vehicle shock absorbing spring with an internal leveling device is provided with a working cylinder which is filled with a buffer medium and arranged in a high pressure chamber under the pressure of a gas cushion acting as a spring. This working cylinder is surrounded by a hollow piston rod and is divided into two working chambers by means of a working piston with a valve. The actuating cylinder is also actuated by a spring motion and has a piston pump for moving oil from the low pressure chamber to the working space connected to the high pressure chamber, which is connected to the working cylinder and the pump chamber formed by the hollow piston rod. It consists of a pump rod. The buffer medium in the pump chamber is then pressurized by the propulsion element.
