The present invention relates to a crankcase ventilation device for a vehicle and, more specifically, relates to a crankcase ventilation device for a vehicle which prevents back flow of blow-by gas to a new air inflow valve in accordance to a rise in pressure and a rise in flow rate inside a crankcase; deterioration inside an engine due to unburned fuel contained in the blow-by gas and minute particles of engine oil, generation of sludge, and an engine failure are prevented; and minimizes contamination of an intake system by providing a new air inflow control valve having a nozzle and a diaphragm, so as to block a back flow of the blow-by gas to a new air inflow hose due to an excessive rise in pressure inside the crankcase during a process of re-circulating and re-burning the blow-by gas discharged from the crankcase of the vehicle. |
