Patent ID: 6840273

Claim:
A manifold valve having a position detecting mechanism, the valve comprising: a solenoid valve for selecting a flow path of pressure fluid and a manifold base mounted with the solenoid valve, wherein the solenoid valve includes a casing having a mounting face to be mounted to the manifold base, a valve member provided in the casing, driving mechanisms for driving the valve member, a magnet mounted to an end of the valve member to detect a position, and a first recessed portion provided at a position of the mounting face corresponding to the magnet, one or more magnetometric sensors for detecting the magnet and a connecting pin to be brought into continuity with the magnetometric sensors are housed in the first recessed portion, the manifold base includes a placing face on which the solenoid valve is mounted, a second recessed portion formed on a position of the placing face corresponding to the first recessed portion, a substrate housing chamber inside the base and connected to the second recessed portion, a sensor connector disposed in the second recessed portion, and a main wiring substrate which is disposed in the substrate housing chamber, which is mounted with an electronic component for signal processing and connectors for feeding and signal transmission, and to which the sensor connector is electrically connected, the sensor connector has a contact which can come in contact with the connecting pin and the contact comes in contact with and is electrically connected to the connecting pin when the solenoid valve is mounted on the manifold base.
