Document Type and Number:
Japanese Patent JP6770748
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a spring receiving member capable of coping with springs of various sizes while improving strength, and a valve assembly including the spring receiving member.SOLUTION: As a spring receiving member 4 has a cylindrical portion 42 extended in an X-direction which is a reciprocating direction of a spool, as an axial direction, strength of the spring receiving member 4 can be secured even on a position free from groove portions 422, 423. Through holes 424, 427 are formed on positions holding the groove portions 422, 423 of the cylindrical portion 42, thus a part of a spring can be disposed or penetrated in the through holes 424, 427, and the large-sized spring can be used. The through holes 424, 427 are independent from each other, and a pillar portion is formed therebetween, so that the strength of the cylindrical portion 42 hardly degrades even through the through holes are formed.SELECTED DRAWING: Figure 6
