摘要： In a normally closed electromagnetic valve (100A, 100B, 100C, 100D), a rod (112,212) is supported so as to be able to move in a first direction toward a valve seat (114b) as well as in a second direction away from the valve seat (114b). This rod (112,212) closes off the hydraulic fluid path when seated on the valve seat (114b), and opens up the hydraulic fluid path when away from the valve seat (114b). When current is not being supplied to a coil (130), a first armature (116,216) pushes the rod (112,212) in the first direction using urging force of a first spring (122). When current is being supplied to the coil (130), the first armature (116,216) moves in the second direction, and the second armature (118) pushes the rod (112,212) in the first direction using electromagnetic force corresponding to the amount of the current. Further inventions are directed to a brake control system comprising such a valve, a control method for controlling a normally closed electromagnetic valve having only one armature and an electromagnetic valve having flow resistance changing means (226,234) inside its armature.

摘要： In an electromagnetic valve in which a valve body unit is housed in a housing, the unit has a plunger including a groove portion at its cylindrical outer peripheral face. The groove portion extends in the cylinder axis direction and moves in the cylinder axis direction by an electromagnetic force generated by an electromagnetic coil. A rod is secured to the plunger and abuts against a valve seat for opening and closing the valve when the plunger is moved to close the valve and releasing the abutment of the rod against the seat when the plunger is moved to open the valve. A cylindrical sleeve covers the outer peripheral face of the plunger and is configured integrally with the plunger. A communication passage defined by the groove portion of the plunger and the inner peripheral face of the sleeve extends in the cylinder axis direction.

摘要： A normally closed solenoid valve includes a valve element arranged to be seatable on and unseatable from a valve seat. A movable core is movable with the valve element. A first spring biases the valve element and the movable core toward the valve seat. A coil and a stator core generate an electromagnetic force resistive to a load of the first spring for the movable core. A second spring applies a load smaller than and resistive to the load of the first spring to the valve element and the movable core. The valve further includes a load adjusting mechanism for adjusting the load of the first spring, and a stroke adjusting mechanism for adjusting an unseating stroke of the valve element from the valve seat.

摘要： An electromagnetic valve includes a housing, a plunger, a spring, and a solenoid. The housing includes a cylindrical guide member configured to assist axial movement of the plunger, a seat member assembled to the guide member with a valve hole formed therein, a stationary core arranged so as to be opposed to an end portion of the guide member at a predetermined distance away therefrom in an axial direction, and a sleeve coupled, in a liquid-tight manner, to each of an outer circumference of an end portion of the stationary core and an outer circumference of the end portion of the guide member so as to integrally couple the stationary core and the guide member to each other. The plunger has formed therein a communication hole passing through the plunger in the axial direction so as to communicate to a passage (communicating to an inlet port and an outlet port) at one end and to a receiving portion of the spring at the other end, and a path for communicating the communication hole and a space portion formed on an inner side of the sleeve at a position between the end portion of the stationary core and the end portion of the guide member. Accordingly, when the working liquid is caused to flow from the inlet port toward the outlet port, the working liquid is caused to flow into the communication hole through the path, and thus air inside the electromagnetic valve can be discharged to the outside by the working liquid flowing from the passage out of the housing.

摘要： An electromagnetic linear valve includes: (a) a plunger including a large outside-diameter portion and a small outside-diameter portion, and (b) a housing having a through-hole and including a large inside-diameter portion in which the large outside-diameter portion is inserted with a clearance being defined between the large inside-diameter portion and the large outside-diameter portion, and a small inside-diameter portion in which the small outside-diameter portion is inserted with a clearance being defined between the small inside-diameter portion and the outside-diameter portion. The plunger has an end portion which serves as a valve body that is to be seated on a valve seat constituted by an opening of the through-hole. The large outside-diameter portion has an end portion constituted by another end portion of the plunger that is opposite to the above-described end portion of the plunger. The clearance between the small inside-diameter portion and the small outside-diameter portion is smaller than the clearance between the large inside-diameter portion and the large outside-diameter portion.
