摘要： Disclosed is a solenoid-operated valve which hardly brings a plunger into a lock and is capable of improving its responsivety. In the solenoid-operated valve, the plunger slidably guided in an inner bore formed in a yoke and a core aligned axially is moved by energizing an electromagnetic coil, and a spool in a valve section is moved through a rod portion which protrudes from an end of the plunger to pass through a center hole of the core. An electromagnetic section fluid chamber defined by a forward end surface of the plunger and the inner bore of the core communicates with an intermediate fluid chamber defined between the core and a valve sleeve, through a clearance between the center hole and rod portion. The spool is provided at one end thereof with a land portion whose end surface defines a part of the intermediate fluid chamber. The diameter of the land portion is chosen to be the same as the diameter of the plunger, so that the sum in volume of the electromagnetic section fluid chamber and the intermediate fluid chamber can be kept invariable regardless of movement of the plunger. A supply/drain passage is further provided to permit the oil around the solenoid-operated valve to be charged into the rear end fluid chamber or discharged therefrom upon movement of the plunger.

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.

摘要： A damper obtaining damping force by the frictional resistance imparted by the viscosity of the magnetic viscous fluid is disclosed. The damper is provided with a seal not only on one (lower side) of the axial outer sides of the yoke but also on the other (upper side) of the axial outer sides of the yoke to trap the magnetic viscous fluid within the magnetic viscous fluid filling portion at both axial outer sides of magnetic viscous fluid filling portion. Because the leakage of the magnetic viscous fluid can be prevented, no air is introduced into the magnetic viscous fluid filling portion, to allow the density of the magnetic viscous fluid within magnetic viscous fluid filling portion to be maintained at a favorable level and prevent degradation of damping force.
