ABSTRACT:
Hydraulic shock absorbing arrangement for pipe conduit systems including a piston slidably mounted in a liquid-filled cylinder to define spaced chambers. The piston has a rod connected thereto which is slidable in a guide positioned at one end of the cylinder. The piston rod is surrounded by a sealing bellows which is secured in a liquid-tight manner at one end to the piston and at its other end to the guide. The cylinder is mounted on a stationary bearing, while the piston rod is connected to a pipe in which shocks are to be damped. A throttling valve communicates with each cylinder chamber, the latter chambers communicating with each other through an overflow path. An expandable compensation bellows communicates with the atmosphere through an air outlet opening, but is otherwise closed.
