FIELD: mining.
SUBSTANCE: flushing assembly of the drilling bit contains the housing with the pressure head channel and the seat for the nozzle fixed by the lock element installed in the toroidal cavity formed by the combined ring grooves on internal surface of the seat and external surface of the nozzle, and the sealing ring. The material for the lock element is the wearproof elastic material which is implemented with a possibility of adding into the toroidal cavity in the liquid state through the radial channel made in the housing and connecting external surface of the housing with the toroidal cavity.
