INRICHTING VOOR HET REGELEN VAN EEN OVERBRENGINGSVERHOUDING VAN EEN TRAPLOOS VARIABELE DRIJFRIEMOVERBRENGING.

摘要

Apparatus for controlling the transmission ratio of an infinitely variable V-belt (14) transmission, provided with a control valve (20) for regulating a fluid flow. The control valve comprises an axially displaceable valve body (21), said valve body being connected by spring means (23) to the armature of an electromagnet (26) whereby the armature (25) upon a slight displacement regulates a fluid pressure which imposes a load on the valve body (21).
