ABSTRACT:
An electromagnetic valve for fluid-dynamic controls is disclosed, which comprises, in addition to the usual valve body and slider, a pressure-tight cylinder made integral with the valve body and coaxial with the slider, communicating with a portion of the valve touched by the hydraulic fluid. This valve portion contains a portion of the fixed magnetic armature and within the latter slides, in contact with its inner wall, the movable magnetic armature, a coil comprising the energization coiling proper and a portion of the fixed magnetic armature, is separated from and slipped onto the pressure-tight cylinder. The result is that the sealing means and gaskets are reduced to a minimum, the assembly is more compact and the operation more reliable.
