摘要

Improvements introduced in two-way two-way reversing valve systems, in particular those driven to solenoids for cooling or other liquids, characterized by comprising the arrangement of a cylinder and two caps at the ends thereof, containing a piston inside integral with a bolt and driven by three magnetizable masses that are inside a casing fixed to the cylinder, being displaceable by means of two solenoids located on this casing, while at the ends of said casing are welded two caps traversed by two screws which, at the same time, serve as stops for the magnetizable masses, thus limiting the piston travel since the bolt attached to it passes through different perforations in the magnetizable masses and one of the cylinder caps, has a small welded pin to the end of which, a spring is attached, the other end of which is fastened to the pin integral to the piston whose slits intercommunicate the conduits arranged in the periphery of the cylinder.
