ABSTRACT:
A PCV valve for use in conjunction with an engine of a motor vehicle that reduces audible noise and increases the efficiency at which blow-by gases are routed to the engine's intake manifold to be re-burned. The PCV valve includes a housing having an inlet and an outlet. A plunger having a first end segment and a second end segment with an intermediate segment therebetween is disposed within the housing. A plunger seat disposed between the inlet and the outlet includes an orifice through which the first end segment of the plunger extends. An inlet plunger guide is disposed in the housing for receiving the second end segment of the plunger and an outlet plunger guide is disposed in the housing for receiving the first end segment of the plunger. Blow-by gases flow between the inlet and the outlet with the plunger moving axially within the housing in response to pressure changes at the outlet to control the flow rate of the gases.
