Title:
ELECTROMAGNETIC VALVE
Document Type and Number:
WIPO Patent Application WO/2019/059385
Kind Code:
A1
Abstract:
A yoke (19) is provided with a notch (19d), notched from two points P1 and P2 on a circumference (19b2) forming a sleeve-side insertion hole (19b1) toward the outside of the circumference (19b2), the notch having a minimum distance between the points P1 and P2 as a width W and the distance from a straight line linking the points P1 and P2 in a direction orthogonal to the straight line as a length L. The width W of the notch (19d) is set on the basis of a target attraction force for attracting a plunger (15), the attraction force increasing with an increase in the width W, and the length L of the notch (19d) is set to be greater than or equal to a prescribed length Ld where the attraction force increasing with an increase in the length L becomes constant at the target attraction force in the set width W irrespective of an increase in the length L.
