Fixed orifice vs variable orifice
Did you know?
WebUnlike fixed orifice type systems, PCV systems that use a variable-flow PCV valve more accurately match ventilation flow with blowby production characteristics. By accurately matching theses two factors, crankcase ventilation performance is optimized, while engine performance and driveability remains unaffected. WebMar 30, 2012 · A reduction in orifice size results in decreased flow as only so much liquid can pass through the orifice. In all of the above cases, the inlet pressure is constant and the outlet pressure is, effectively, zero (atmospheric) as there is nothing to restrict flow on the exit side of the orifice. How much liquid passes through the orifice depends ...
WebJun 2, 2012 · The variable orifice has a spring loaded piece that acts basically as a pressure regulator to keep a desired pressure difference.

WebThe variable orifice valve will adjust it’s flapper (disc) to close more so that the flow through the outer fixed orifice plate holes will remain constant. The delta p through the outer fixed holes will remain constant therefore the velocities through these holes will remain below sonic conditions WebVariable Orifice. (To be removed) Generic hydraulic variable orifice. The Hydraulics (Isothermal) library will be removed in a future release. Use the Isothermal Liquid library instead. (since R2024a) For more information on updating your models, see Upgrading Hydraulic Models to Use Isothermal Liquid Blocks.
