  • Particle-delivery in abrasive-jet systems
    Patent number: 9138863
    Abstract: Particle-delivery devices, abrasive jet systems, and associated devices, systems, and methods are disclosed herein. In certain aspects, the particle-delivery devices can include an elongated fluidizing chamber and a metering assembly. The metering assembly can include a particle flow path extending from the fluidizing chamber. The metering assembly can also include a carrier-gas passage extending to an injection orifice proximate the fluidizing chamber. The metering assembly can be configured to inject carrier gas into the fluidizing chamber to fluidize particles within the fluidizing chamber. Fluidizing the particles at different carrier-gas pressures and/or flow rates can change the rate of particle delivery. For example, the metering assembly can include a metering opening and a regulator configured to change a steady-state pressure and/or flow rate of carrier gas entering the fluidizing chamber.
