FIELD: mechanical engineering; hydraulics. SUBSTANCE: proposed hydraulic cylinder is designed for transforming energy of working liquid flow into mechanical energy of reciprocating moving member. Hydraulic cylinder has piston with rod arranged in housing to form working spaces, end face covers, multirow rolling supports of piston and rod. Bodies of rolling of piston and rod rolling supports are made in form of spiral springs arranged in grooves made over perimeter of piston and rod of hydraulic cylinder. EFFECT: improved reliability. 7 dwg |
