Abstract
An apparatus and a method for fluid distribution and control. A valve body defines at least two pairs of chambers which are each connectable to an external fluid circuit. A mobile structure, which moves according to a controlling unit, forms an internal penetrating passage. An internal bearing surface, which is located at the first end of the internal passage, is capable of cooperating in a sliding manner with a stationary piston head. The internal bearing surface may move beyond either side of the piston head. When the mobile structure is in an extreme position, an end chamber of the valve body is in fluid communication with the internal passage. When coupled with a PSA adsorber system, the system is capable of supplying oxygen enriched air to an occupant of an aircraft.
