    摘要： Venturi devices and systems incorporating the same are disclosed. The Venturi devices include a lower body defining a passageway having a motive section and a discharge section spaced a distance apart from one another to define a first Venturi gap and a second Venturi gap downstream of the first Venturi gap at a position that divides the discharge section into a first portion between the first and second Venturi gaps and a second portion leading away from the second Venturi gap, and include an upper body defining a suction passageway in fluid communication with both the first and second Venturi gaps. The motive section and the discharge section converge toward the first Venturi gap.

    摘要： An engine system having a compressor coupled to an engine and supplying air to an intake manifold, a throttle controlling the supply of air from the compressor to the intake manifold, a vacuum reservoir, an aspirator having its motive section in fluid communication with the air intake system upstream of the compressor and its discharge section in fluid communication downstream of the compressor and a suction port in fluid communication with the vacuum reservoir, a compressor recirculation valve having a pneumatic control chamber in fluid communication with downstream air from the compressor and in fluid communication with the vacuum reservoir, a gate valve controlling the fluid communication of the pneumatic control chamber of the compressor recirculation valve with the downstream air and the vacuum reservoir, and a bleed line having a bleed valve in fluid communication with the vacuum reservoir and the pneumatic control chamber of the compressor recirculation valve.
