Abstract: A method for preventing a valve orifice from switching to the small size when a high build gradient is required includes briefly bleeding off a small amount of fluid at the upstream side of the valve. This momentarily reduces the pressure difference when beginning the pressure build. After the valve is opened with the large orifice, the fluid flow through the valve prevents a high pressure difference. The resulting build with the large orifice has the maximum pressure gradient.

Abstract: A solenoid valve for brake systems, including a spool movably set in a valve housing, provided along its central axis with the first orifice which has a predetermined diameter, and provided at a position around the plunger with a plunger guide having a predetermined depth for allowing the plunger to enter the spool, thus opening and closing the first orifice. A valve seat portion is formed on the inner surface of the bore of the valve housing by stepping the surface. This valve seat portion defines the second orifice therein, and comes into contact with or spaced from the end of the spool to selectively open the outlet, separately from the first orifice when the spool moves in either direction. The second orifice has an inner diameter larger than that of the first orifice. A spool restoring spring normally biases the spool toward the plunger.

Abstract: A fluid pressure control device having a housing formed with a bore and a solenoid valve mounted in the bore. The solenoid valve has a frame of a magnetic material mounted in the bore. The frame and thus the solenoid valve are mounted in the bore of the housing and secured in position by a pin received in a hole formed in the frame and supported by the housing. This eliminates a seating plate for securing the solenoid valve against the housing. This contributes to a compact design, light weight and lower manufacturing cost.
