FIELD: study of behavior of extrudate in compressor valves and in leakage spaces of single-screw presses. SUBSTANCE: facility includes cylindrical base carrying tensometer ring, support carrying small tensometer ring put on cylindrical base, die with strain-gauge transducers mounted on this ring, compression chamber formed by cylinder having firm contact with die, support and plunger. Cylindrical base is placed on faceplate fitted with rod carrying strain-gauge transducers measuring torque. Piston is put on rod. Faceplate with electric motor drive is installed on bearing block. Piston and die are mounted for rotation of one relative another with variable angular speed. EFFECT: expanded functional capabilities and application field of facility. 2 cl, 3 dwg
