Variable flow reducing valve for compressed air injection engine comprising high pressure air tank and buffer capacity utilizes pilot valve cams controlling rocker arm rods to change lever arm ratio and determine valve lift

摘要

The variable flow reducing valve for compressed air injection engines comprising a high pressure compressed air tank (30) and a buffer capacity (31) comprises a system for controlling the stroke of the piston. The air supply in the final use buffer capacity and the supply to the cylinders are ensured by pilot valves. The pilot valve cams (15) which are used to control the rocker arm rods (19,19A) are positioned directly on the flanges of the camshaft (14) and each rocker arm (20A,20B) pivots around a mobile shaft (21) that can move between its two ends, thereby enabling the changing of the lever arm ratio which determines the valve lift according to the rocker arm rod movement.
