Adjusting cylinder of a camshaft adjusting device acted upon by a separate oil supply unit

摘要

A device provided on a internal combustion piston engine for changing the rotational relations between at least one camshaft (5) and a crankshaft (6) includes a hydraulic cylinder (4). This hydraulic cylinder (4) is acted upon by a supply unit (7, 14) which displaces gas cushions in the hydraulic cylinder (4) when the internal combustion piston engine is at a standstill and replaces the gas cushions with hydraulic cylinder, especially motor oil.
