Operating cylinder for energy conversion - has cylindrical shell tapered zones formed on two end sections with piston rod

摘要

Operating cylinder for energy conversion, with a piston which is axially adjustably supported in a cylindrical shell closed at one end where the piston rod passes through one end wall and there is a pipe line connecting device opening into the shell for fluid or gaseous media. The cylindrical shell (1) has tapered zones (23) formed on the two end sections and ending in threaded stubs (4, 5). The piston rod (7) passes through one stub with play and at the connections one of the following mechanisms is fixed, a piston rod guide (11) with a piston rod seal (12) a pipe line connecting device (8, 9) a piston rod guide (11) with piston seal (12) and with a pipe-line connecting device (9, 13, 16) which opens into the annular chamber (15) between piston rod and a connection.
