CAVITATION INJECTOR Russian patent published in 2004 - IPC

FIELD: underwater cleaning technology; injectors with compensated force of escaping water jet. SUBSTANCE: proposed cavitation injector has body with central flow-through passage formed by inlet diffuser, expansion chamber and outlet diffuser. Injector is additionally provided with compensator secured on body in area of outlet diffuser. Inner cavity of compensator is made in form of diffuser at outlet which changes to ring-shaped slotted chamber and then to expansion chamber. Expansion chamber formed between outer wall of injector diffuser and inner wall of compensator body is brought into communication with space after diffuser by means of through passages which are made in compensator body. Compensator body may be mounted on injector body for longitudinal motion along injector body and may be locked in any required position. EFFECT: considerable compensation of recoil of working jet of liquid escaping from injector. 2 cl, 1 dwg
