  • Patent number: 6886597
    Abstract: The invention concerns an electrovalve proportional to a field current supplying the field coil (5) axially enclosing a mobile core (76), whereto is secured a push rod (16) sliding in a polar component (9) of the fixed magnetic circuit co-operating with the field coil, actuating a shutter (2, 3) comprising at least a valve (25, 26) co-operating with a seat (28, 29) to open and close the shutter, return means (32, 33) providing it with a stable neutral position relative to the seal when the field current is null, each valve being coaxial to the push rod and actuated thereby. The invention is characterized in that the mechanical linkage between the stem of each valve (17, 27) and, either the stem of the adjacent valve, or the push rod, constitutes a punctual contact.
