A high pressure separator/accumulator that uses dual bellows is provided. The dual bellows are not mechanically linked but rather operationally coupled through a fluid medium. The high pressure separators includes a housing defining a first internal space. The housing is in fluid communication with a first fluid system and a second fluid system. A first bellows is coupled to the interior of the separator and defines a space with a variable volume. The space is in fluid communication with the first fluid system. A second bellows is coupled to the interior of the separator, generally opposed to the first bellows, and defines a space with a variable volume. The space is in fluid communication with the second fluid system. The two fluid systems, however, are isolated from each other by the separator. The housing is charged with a fluid medium that transmits force between the first and second bellows.

A sealed dual coaxial rotary shaft feedthrough device is provide. The device includes an inner shaft and a hollow outer shaft that is coaxial to encompass the inner shaft. The shafts include coupled drive and driven shafts. The coupling, which may be referred to as an eccentric coupling, causes the driven shaft to rotate with the drive shaft. The rotation is transmitted without breaking the seal by an eccentric portion of either the drive or driven shaft being nutatingly coupled to either a transition cap or transition cup. Nutatingly coupled means rotation of the shaft causes the transition cap or cup to orbit, but not spin, about the longitudinal axis. The nutation is transmitted by the transition cap or cup to the other of the shafts, which rotates.
