<p>The hydraulic system pressure accumulator comprises a cylinder with a free piston, connected on one side of the latter to the system and containing on the other a cushion of compressed gas, the volume of the latter being increased by a bottle parallel to the cylinder and connected to it by flanges and a pipe bend. The two ends (22) of the bend (2) are turned cylindrically with their axes parallel. Their length is approx. 1.5 times that of the pipe dia. The end wall of the cylinder and the opening (32), enclosed by a flange ring (31), in the bottle, have stepped bores, the larger-dia. portions of which accommodate the pipe bend ends, which have semicircular-section annular grooves (23,24) for a distance from the end faces greater than the depth for which the ends are inserted in the bores.</p> |
