MrTim asked that I post the following bellows device from Hiscox's "Curious Mechanical Mechanical Movements" (Lindsay Publications, 1984, original copyright 1904)
He is right that this device is relevant to the discussion of possible fluid mechanical PM solutions.
I should note, however, that Hiscox presents this device as an example of false PM, since the weights that press the fluid must move into postions that otherwise offset the alleged static imbalance.
