Title:
ELECTROMAGNETIC VALVE AND FLUID PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2017057997
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a variation of a flow rate of an electromagnetic valve.SOLUTION: A booster linear valve 160 includes two movable elements 182, 184. By the control of a supply current to a coil 180, the second movable element 184 is switched to a stationary state, the first movable element 182 is switched to a movable state, the first movable element 182 is switched to a non-movable state, the second movable element 184 is switched to a non-movable state, and both the first movable element 182 and the second movable element 184 are switched to movable states. Therefore, it becomes possible to mechanically set an opening of the booster linear valve 160 at an intermediate opening. A variation of a flow rate between the booster linear valves can be reduced compared with the case that the opening is continuously controlled by the control of the supply current from a closed state up to a maximum opening.SELECTED DRAWING: Figure 2
