Vct - a system with control valve prestressing in the case of low pressures and not under prestress of the control in the case of normal operating pressures

摘要

a camshaft has at one end thereof attached to a slider, hereby oscillating rotation to carry out.the camshaft is also a kettenrad, together with the cam shaft is able to rotate, but with this and herschwingen.the slider has opposite bulging in the opposite ausnehmungen of kettenrades are arranged.the ausnehmungen possess a larger umfangsmau00df than the bulging, so that the valve and the kettenrad relative to one another back and herschwingen,in this way, the phase of the camshaft relative to a crankshaft to change whose phase relative to the kettenrad a middle class crawler is fixed.the camshaft tends to change in dependence of pulses, which are at their normalbetriebes is exposed, and can only in a predetermined direction.either as a voreilung or nacheilung, changing the flow of a hydraulic stru00f6mungsmittels, preferably of engine oilthe ru00fcckfu00fchrleitungen of the ausnehmungen either blocked or willby making the position of a steuerschiebers within a ventilgehu00e4uses a steuerventils in dependence on a signal is controlled.a motorbetriebszustand a motorsteuereinheit says. the control valves are positioned either within the ventilgehu00e4uses by gegenu00fcberliegendes end shall be..
