    摘要： A safe, double solenoid type electromagnetic valve which can be used as a single solenoid type electromagnetic valve and in which a main valve member does not change from one change-over position to another even when electric power is supplied to two pilot valves at the same time. A first piston is disposed at one end of the main valve member while second and third pistons are disposed at the opposite end. The first and second pistons have the same diameter while the third piston is smaller in diameter than the first two. Two solenoid mechanisms are provided for making a pilot fluid operate on the first piston as well as the second and third pistons. A change over device is also provided which is able to change over the operation from a first situation where the pilot fluid is allowed to operate on both the second and third pistons to a second situation wherein the pilot fluid is allowed to work only on the third piston.

    摘要： A directional control valve having a position detecting function, is capable of detecting the operating positions of the valve member over the whole stroke thereof, without using a magnet and a magnetic sensor. A position detection mechanism 20 for detecting operating positions of a spool includes a detection coil disposed on a casing and generating an alternating magnetic field; a detection head mounted on a piston and changing the impedance of the detection coil by approaching or moving away from the detection coil in the alternating magnetic field; and a signal processing circuit applying an alternating voltage to the detection coil and detecting operating positions of the spool from the change in impedance of the detection coil.

    摘要： Inexpensive three-port solenoid valves that can be connected to five-port solenoid transfer valves and allow the axial movement of valve discs to be stably guided, are provided. Two valve discs constituting a three-port valve are inserted into a five-port valve body having a supply channel opened at the center of a valve hole; output channels are open on the respective sides of the supply channel; and ejection channels are open on the respective sides of the output channels. A pilot-valve section is used to drive the valve discs. The valve discs use the fluid pressure in the supply channel as returning force for the valve bodies, and each have seal members for switching the output channels between the supply channel and the ejection channels respectively, for communication; and guide sections and for guiding the axial movement of the valve discs, wherein a fluid groove for a fluid flowing through the channel is provided between the plurality of axial guide sections.
