Abstract: A valve comprises a cup-shaped element presenting an outer surface on which a driver element is mountable and, inserted in said cup-shaped element, a core comprising at least one seal element arranged to block a first fluid passage provided in a bush, said core being movable within said cup-shaped element against the action of an elastic element between a first position in which said seal element rests on said bush such as to close its first passage and a second position in which said seal element is detached from said bush such as to open its first passage, said bush being associated with a closure element for the cup shaped element, the closure element presenting, for its fixing to the cup-shaped element, means cooperating with an inner surface of said cup-shaped element.

Abstract: A refrigerant accumulation and oil recovery device for recovery/regeneration/recharging units for a refrigerant fluid withdrawn from refrigeration or air conditioning plants or heat pumps, characterized by comprising a refrigerant fluid accumulation/evaporation vessel and an oil recovery vessel, said vessels being closed at their top by at least one plate which supports them both, the plate presenting a plurality of passages defining, with said vessels, a part of the charging/recycling circuit of said recovery/regeneration unit, in which said accumulation/evaporation vessel and said oil recovery vessel present at least one wall in common, such that any refrigerant fluid leakage from one of said vessels at the connection interface between said common wall and said plate is recovered into the other.
