摘要: An aspirator for creating vacuum is disclosed that includes a housing defining fluid passageway with first tapering portion and second portion. Each has larger internal opening smaller opening, the openings facing one another. The gate positioned between in communication portions, having Venturi tube when flows direction creates opposite direction. are suction port, tubes may provide different mass flow rates through aspirator. engine system an bore actuator also disclosed.
