Title: Solenoid reversible valve system
Inventor: ISHIJIMA SADAO
IPC: F16K31/06
Filed: 1990-04-11
Abstract: PURPOSE:To dispense with any pilot valve by opening or closing an opening, deflected in the axial direction of a valve box, with a combined valve element with a pressure transfer port slidden, moving the valve element with a movable core equipped with a return spring, and regulating it with a bracket. CONSTITUTION:Each of valve seats 2a, 2b, where fluid passages 1a, 1b deflected in the axial direction are opened, is installed in a cylindrical valve box 1. Each of pressure transfer ports 4c, 4d is installed in a combined valve element 4 with each of telescopically fitted, cylindrical first and second valve elements 4a, 4b and seal parts 4e, 4f, making them slide between the valve seats 2a and 2b. When a solenoid coil 13 is turned to ON, the combined valve element 4 is attracted together with a movable core 7, interconnecting an interval between openings, and when it is turned to OFF, this interval between the openings is closed by energization of a return spring 8 and positioning action of a bracket 9. Thus, such a reversible valve system as requiring no pilot valve is securable without using a pressure differential.

Abstract: PURPOSE:To simplify constitution by operating an output relay for a prescribed time after a set time through the operation of a switching element by a differential output from a differentiating circuit. CONSTITUTION:When electric power is applied to a power terminal 12, a timer circuit 18 operates to invert a signal at its output terminal from a level L to an H a set time later.

Filed: 1987-04-17
Abstract: PURPOSE:To increase the hydraulic pressure of a rear wheel cylinder when one system falls into failure by supplying the hydraulic pressure to the rear wheel cylinder by means of a hydraulic pressure control valve, determined by a stepped piston ratio. CONSTITUTION:While two systems of a master cylinder 2 are normal, the stepped piston 23 is pressed to a left direction and stays still as being pressed. On the other hand, at the time of the failure of the hydraulic pressure of the front side system, the stepped piston 23 moves toward a right direction as resisting a compression spring 37, and closes the liquid path 35A. Then, the liquid in a third hydraulic pressure chamber 33 is supplied to the liquid path 35B of the rear wheel cylinder up to the hydraulic pressure PRII, determined by a sectional area ratio between the small diameter part 23a and the large diameter part 23b of the stepped piston 23, and the hydraulic pressure PRII is increased higher than the hydraulic pressure PMR of the master cylinder. Thus, at the time that the system of one side falls into the failure, the hydraulic pressure of the rear wheel cylinder can be elevated higher than the hydraulic pressure of the master cylinder.
