众所周知,液压挺柱是介于凸轮轴凸轮和气门之间的无间隙传力机件。从传力方式上可分为直推式(无摇臂,气门升程等于凸轮升程)和摇臂式(摇臂有大于1的杠杆比,气门升程大于凸轮升程)两种。
As we all know, hydraulic tappet is interposed between the camshaft cam and valve clearance force transmission parts. From the transmission of force can be divided into direct thrust (no rocker, valve lift equal to the cam lift) and rocker arm (rocker lever ratio greater than 1, the valve lift greater than the cam lift) two.
