Title:
電磁弁及び電磁アクチュエータ
Document Type and Number:
Japanese Patent JP6776668
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a solenoid valve capable of preventing the movement of a bush being inhibited due to cutting chips even when cutting chips generate when press-fitting the bush in a solenoid case, and to provide an electromagnetic actuator.SOLUTION: A solenoid part 2 of a solenoid valve 1 includes: a solenoid case 21 fixed to a sleeve 3; a bobbin 22 held in the solenoid case 21; a coil 23 wound around the bobbin 22; a cylindrical plunger 24 moving in an axial direction with respect to the solenoid case 21 by receiving a magnetic flux which the coil 23 generates; and a cylindrical first bush 27 fixed by being press-fitted in the axial direction inside the solenoid case 21, and for guiding the axial direction movement of the plunger 24 with respect to the solenoid case 21. In the solenoid case 21, a recess 210 in which cutting chips C generating when press-fitting the first bush 27 are introduced is formed by opening to a corner part between a fitting surface 213a and an abutting surface 213b against which the first bush 27 is abutted.SELECTED DRAWING: Figure 1
