Title:
VALVE FOR HYDRAULIC BRAKE DEVICE OF AUTOMOBILE
Document Type and Number:
Japanese Patent JP3946797
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make a cross section of a pin at least almost correspond to a sealing cross section of a valve seat by almost compactedly receiving a single pin movable in the lengthwise direction in a vertical hole by being supported with an end wall of a valve dome.
SOLUTION: In an electromagnetically operable valve 1 for a hydraulic brake device of an automobile, the valve is provided with a seal valve 29 movable to a closing position against force of a return spring 30, an armature 20 to cooperate with a push rod and a single pin movable in the lengthwise direction by being almost compactedly received in a vertical hole 37 of the push rod, and is constituted in a shape which a cross section of the pin at least almost corresponds to a sealing cross section of a valve seat 28 of the seat valve. In this case, the armature and the push rod are individual two constitutive parts supported by frictionally joining the armature and the push rod to each other, and the vertical hole of the push rod continues into the armature, and pins 41 and 46 are constituted as a two-part structure, and a second part 46 extends in a vertical hole 45 of the armature.
