摘要： A waste compaction apparatus may include a housing and a connector arm. The housing may define a drive chamber and a compaction chamber and the connector arm may include a drive piston portion movably positioned within the drive chamber and a compaction piston portion movably positioned within the compaction chamber. The drive chamber may be selectively fluidly coupleable to the near-vacuum of outer space, such that the compaction piston portion of the connector arm is configured to move within the compaction chamber to compact waste material contained within the compaction chamber in response to movement of the drive piston portion of the connector arm within the drive chamber.

摘要： A microgravity urine collection apparatus may include a bellows defining an internal chamber having a selectively adjustable volume. The bellows may include an inlet and an outlet. The microgravity urine collection apparatus may further include a first valve coupled to the bellows and configured to selectively control fluid flow through the inlet. The microgravity urine collection apparatus may also include a second valve coupled to the bellows and configured to allow fluid flow out of the bellows via the outlet and prevent fluid flow into the bellows via the outlet.

摘要： A dosing pump according to an exemplary aspect of this disclosure includes, among other things, a first chamber having an outlet fluidly coupled to a mixing area, and a second chamber having an outlet fluidly coupled to the mixing area. The dosing pump further includes a piston moveable between a suction position and a discharge position. The piston has a first head portion moveable within the first chamber, and a second head portion moveable with the second chamber. Further, movement of the piston from the suction position to the discharge position discharges fluid from the first and second chambers into the mixing area.
