Control Valve regulating the supply and discharge of Fluid to for example a set of Hydraulic Cylinder and piston that is part of a Hydraulic Circuit

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).
