FIELD: technological processes. ^ SUBSTANCE: bar is fixed on a rod of the power cylinder, pistons are established with possibility of axial migration concerning an external surface of the bar, and segments are established with possibility of radial migration. The internal cylinder is rigidly established on the power cylinder with the step flange executed with two parallel patches, the resilient members, two basic sleeves contacting to external surfaces of cylindrical pistons. There are also resilient members and the intermediate shirt which has been put on an external surface of segments. The bar is executed in the form of the hollow external cylinder with possibility of axial migration concerning the internal cylinder and has a flange on one end and a slot contacting with patches of a stepped flange of the internal cylinder on other end. The pistons are executed cylindrical with flanges and segments with face borings for placing of basic sleeves inside and are fixed on an external surface of basic sleeves by ring springs. The cavity between an external surface of the external cylinder and internal surfaces of basic sleeves and segments is filled by resilient members. ^ EFFECT: expansion of technological possibilities and provision of its universality. ^ 4 cl, 2 dwg |
