日本SMC原裝液壓緩沖器

當(dāng)液壓緩沖器受到碰撞壓力時，動能經(jīng)塞頭和加速彈簧轉(zhuǎn)給活塞,，使其向右運動,。原來緩沖器工作腔內(nèi)裝有一個復(fù)位彈簧,、頂桿以及油液?；钊倪\動擠壓工作腔內(nèi)的油液,，使其復(fù)位彈簧壓縮，同時使油液從活塞與頂桿之間的環(huán)形間隙擠壓出來,，進(jìn)入貯油腔,。在活塞開始運動時，由于與頂桿之間的環(huán)形間隙較大,，油液容易被擠出,；在活塞繼續(xù)運動時中，這一環(huán)形間隙變得越來越小,，即活塞阻力不斷增大,，到頂桿的圓柱形階段后，環(huán)形間隙為零,，阻力也穩(wěn)定于zui大值,。緩沖器被壓縮的過程是通過活塞擠壓油液做功的過程。這一過程消耗了大量動能,，起到緩沖作用,。當(dāng)工作完畢，活塞被復(fù)位彈簧推至原始位置,，完成一個工作循環(huán),。
