This allows the blow-by gases, consisting of the combustion products and the oil vapours, to be vented through a PCV (positive crankcase ventilation) valve out of the crankcase. There are three system architectures when the blow-by gas exits the crankcase. It can either enter the air inlet manifold (closed CVS), be vented freely in the atmosphere (open CVS) or be vented in the atmosphere through a filter (filtered open CVS).

When piston move t.d.c to b.d.c caused low pressure in cylinder compare with atmospheric pressure and this way produce vacuum and tends to press plunger valve for equivalent.
