Abstract
Provided is a bi-directional PCV valve assembly, system and method. The bi-directional PCV valve may include a fluidic geometry that allows for a flow of fluid a high flow rate in one direction, forward flow, and a low flow rate in the opposite direction, reverse flow. The reverse flow includes a swirling flow that increases the pressure drop and reduces the flow rate to a third of the flow rate of the forward flow. The disclosed assembly produces a strong swirling flow (vortex) in the reverse direction and an efficient (low pressure drop) flow in the forward direction.
