Abstract

FIELD: borehole hydraulic mining. SUBSTANCE: working headpiece includes a case with axial and radial passages with valve seats for discharged central and additional ball valves. Central ball valve is made of deformable material. The valve has additional replaceable cylindrical insertion piece with central passage, with two-layer walls such as internal wall made of hard material, and external wall of deformable material. Radial hole may be originated in the replaceable insertion piece. EFFECT: high performance. 3 cl, 4 dwg
