    摘要： An aspirator assembly for inflating an emergency slide. The aspirator assembly includes a bell housing, a mixing chamber, and a nozzle assembly. The bell housing includes a ring defining an inlet port at which a check valve is located and into which ambient air can flow. The mixing chamber has an outlet port, The nozzle assembly is located in the mixing chamber and includes plural passageway sections defining concentric rings and cross bars. The passageway sections include internal passageways in communication with plural nozzle jets through which a compressed air is introduced into the mixing chamber to mix with the ambient air. The passageway sections are of an airfoil shape cross-section having a rounded leading end directed towards the inlet port and a trailing end is directed toward the outlet port to reduce air turbulence within the mixing chamber.

    摘要： An aspirator may comprise an aspirator body defining an air channel. An aspirator barrel may have a first aspirator barrel segment coupled to the aspirator body and may have a second aspirator barrel segment. The second aspirator barrel segment configured to fit at least partially within the first aspirator barrel segment when the aspirator barrel is in a stowed state and configured to interlock with the first aspirator barrel segment in an extended position when the aspirator barrel is in a deployed state.

    摘要： An aspirator may comprise an aspirator body defining an air channel and an inlet. A flow straightener may be disposed at the inlet. The flow straightener may be configured to produce a laminar flow through the air channel. An aspirator barrel may be coupled to the aspirator body and may define an outlet. A static airfoil assembly may be disposed at the outlet. The static airfoil assembly may be configured to produce a vortex flow exiting the aspirator barrel.

    摘要： An assembly for controlling the eductive dispensing of multiple chemical fluids is described. The assembly is designed to detachably engage with existing eductor valve assemblies as either an original part or as a replacement part. The assembly comprises a plurality of selector gears that rotatably engage with eductor valve assemblies. The selector gears are in communication with a control gear. When the assembly is attached to a plurality of eductor valve assemblies an individual can control the rotation of multiple valve assemblies by rotating a single control knob.

    摘要： A system for moving a wide variety of materials using a recirculating liquid jet pump is described. The system is preferably equipped with an material collection reservoir enabling the placement of material to be suctioned into the collection reservoir without bringing together the material to be suctioned with the motive fluid of the liquid jet pump. The collection reservoir is also connected to a removal means and controller so that suctioned material can be removed from the collection reservoir concurrently with action of the liquid jet pump.
