Claim:
A valve, for pressurized fluid in an air cooling/heating apparatus having at least one duct, comprising: a first duct receiving a first restrictor and a second restrictor, wherein both of said restrictors formed with a capillary through which said pressurized fluid passes and which causes rapid expansion of said fluid when said fluid exits from a distal end of said capillary; wherein the outer surface of said restrictors is in direct contact with the interior surface of said first duct; and said first restrictor is fixed within said first duct and said second restrictor is axially movable within said first duct said first restrictor has a longitudinal end with a conical surface in sealing contact with a flared connecting pipe; and said second restrictor has an outer portion formed with at least two radial fins, said fins cooperating with the interior surface of said first duct to create at least one flow channel for fluid flow, said second restrictor axially movable from a first position in which a sealing member of said second restrictor is in sealing contact with a shoulder formed within said first duct to a second position in which said second restrictor is in contact with said first restrictor.
