ABSTRACT:
An improved transfer chamber for a space vehicle has an enclosure mounted on the hull of a spacecraft, and is provided with inner and outer doors. Two bladders are placed within this transfer chamber, and are selectively movable toward and away from one another. Conduits communicate these bladders with an outer reservoir exposed to space pressure, and with an inner reservoir exposed to cabin pressure. The conduits, bladders and reservoirs are all filled with liquid. When it is desired to egress an object from the cabin to space, liquid is pumped into the bladders, which move toward one another and deform about the object. This reduces the volume of air which is lost to space when the outer door is opened.
