Abstract
A solenoid valve assembly has a valve body in which a spool is slidably mounted and operated by a solenoid having a coil. A manifold member has a plurality of flow paths for supplying and discharging pressurized fluid to and from ports of the solenoid valve assembly. An intermediate block is interposed between the valve body and the manifold member. The intermediate block has a plurality of through holes for connecting ports of the manifold member to ports on the valve body. At least one sensor is housed in the intermediate block for sensing at least one of pressure and flow in at least one of the through holes.
