In Audi A4 at each actuating of the valve it occurs automatically at the expense of so-called hydraulic alignment клапанного a backlash which is carried out тарелочными by pushers. From here and the name "hydropushers". Actuating of valves by means of hydropushers: oil under a high pressure is represented by red colour.
