Abstract

Servoválvula hidráulica perfeccionada que incluye una corredera distribuidora mandada por un electroimán de émbolo colocado según el mismo eje, caracterizada por el hecho de que la corredera y el émbolo están simplemente en contacto una con otro en el interior de una cámara sin presión, mientras que los dos extremos opuestos de una y otro están colocados, respectivamente, en cámaras de extremo conectadas a la presión hidráulica distribuída.
