ABSTRACT:
A joint which may be used in a diving suit includes a plurality of annular members each having a piston and cylinder portion which are coupled together whereby the connecting members are connected in series. The piston and cylinder portions define chambers which are filled with oil and each connecting member has valves which enable communication of the oil between adjacent connecting members as the joint is flexed. A slidably anchored gimbal mounting is provided for each valve in order to preserve the flexibility of the joint without impeding valve action and in order to prevent pullout of the adjacent piston and cylinder portions. The piston and cylinder portions each include inner and outer annular walls and the inside surfaces of the annular walls of the cylinder portions are spherically curved. The annular walls terminate in respective circular rims which are oppositely staggered. This facilitates assembly on the annular connecting members. A further arrangement ensures that the oil chambers in the serial chain on connecting members each receive an adequate supply of oil.
