摘要： Disclosed is a solenoid-operated valve which is capable of enhancing the responsivety of a device while an electric current applied thereto is in a low current range, and which is capable of preventing the device from vibrated by the fluid pressure fluctuation while in a high current range. A spool is received in a valve sleeve for regulating the pressure of fluid. A plunger is received in a stator that has a core provided with an annular projecting portion. A solenoid magnetizes the stator to attract the plunger so as to move the plunger into the annular projecting portion. The annular projecting portion is formed with a tapered portion and a thin cylindrical portion projecting from the rear end of the tapered portion. A step is formed on the outside of the annular projecting portion between the tapered portion and the thin cylindrical portion.

摘要： In a solenoid valve 10, an annular oil groove 66 is formed at a portion corresponding to a spring chamber 56 on the external surface of a sleeve 19, a drain passage 68 is formed to make an upper part of the annular oil groove 66 communicate with the outside of an insertion bore 61, and a throttle hole 67 is provided at a lower part of the annular oil groove 66 for making the annular oil groove 66 communicate with the spring chamber 56. Since the annular oil groove 66 communicates with the outside of the insertion bore 61 at its upper part through the drain passage 68, it can be realized to store the operating oil to the height of the upper part of the annular oil groove 66, so that the operating oil can be reserved in the spring chamber 56 which communicates with the annular oil groove through the throttle hole 67. Further, the operating oil is supplied from a feedback port 48 next to the spring chamber 56 through a clearance between the spool valve 19 and a valve hole 18. Thus, the solenoid valve 10 is able to secure the damping effect of the working oil on the spool valve 19 and a plunger 17 and to suppress the self oscillation even while being operated in the atmosphere for a long time.

摘要： An electromagnetic drive device for lineally reciprocatilvely moving an operating member like a spool of a spool valve is reduced in the manufacturing cost without being degraded in its operational performance. In the electromagnetic drive device, a stator body is excited by an electromagnetic coil to axially move a plunger guided in an inner bore of the stator body, against the resilient force of a spring. The stator body is constituted by arranging a plurality of core portion annular plate elements made of a magnetic material, a plurality of yoke portion annular plate elements made of a magnetic material and a plurality of non-magnetic portion annular plate elements made of a non-magnetic material and placed between the core portion annular plate elements and the yoke portion annular plate elements and by piling up and bodily joining these annular plate elements in axial alignment with one another. Each of the annular plate elements is provided with plural embossed portions each of which is half-blanked to be prominent at one surface side and hollow at the other surface side. The embossed portions formed on each annular plate element are fit at the prominent surface sides thereof respectively in the hollow surface sides of the embossed portions formed on another annular plate element, so that all the annular plate elements can be bodily joined in axial alignment with one another.
