DEVICE AND METHOD FOR CREATING FLUID JETS DIRECTED SIDEWARD Russian patent published in 2012 - IPC B24C3/32 B24C5/04 

FIELD: process engineering.

SUBSTANCE: invention relates to abrasive-jet machining. Nozzle system comprise nozzle body, material inlet element, fluid inlet element, nozzle throttling element to receive fluid from fluid inlet element, discharge element, fluid flow-through element, and material flow-through element. Fluid flow-through element is arranged between fluid inlet element and discharge element. Fluid flow-through element has inlet and outlet sections. Nozzle throttling element is arranged between flow-through element inlet and outlet sections. Flow-through element inlet sections has flow direction variator. Flow-through element outlet section incorporates flow-through feed element for passage of fluid jet created by throttling element. Flow-through feed element comprises outlet element for passage of fluid from nozzle system. Material flow-through element is arranged between material inlet and fluid flow-through element outlet section. Distance between axial line of throttling element and nozzle system outer edge equals or is smaller than 12.7 mm.

EFFECT: machining difficult-to-access parts.
