FIELD: machine building.SUBSTANCE: piston rod consists of cylindrical rod with side surface being provided with first threaded section 1, working section 3, thrust ledge 4, piston locating surface 5 and second threaded section 6. Note here that taper 9 made at acute angle to rod axial line for transition to smaller diameter is made ahead of working section 3. Piston locating surface mid part has free section 10 in diameter smaller than that piston locating part. This allows a better reparability of the piston.EFFECT: better reparability of the piston.15 cl, 5 dwg |
