Title:
LINEAR SOLENOID VALVE AND ITS ASSEMBLING METHOD
Document Type and Number:
Japanese Patent JPH04171508
Kind Code:
A
Abstract:
PURPOSE:To prevent the variance of quality caused among the linear solenoid valve products and to improve the reliability of these valves by performing the adjustment in order to secure the coincidence between the stroke position of a plunger set to the prescribed electric signal value set at an electromagnet part and the spool position set against the prescribed output pressure of a pressure control valve. CONSTITUTION:An electromagnet part 3 is set so that the sucking force of a plunger 37 produced by an electromagnet has the sloping characteristic which varies by the stroke position of a plunger. Then the part 3 is adjusted so that the substantial coincidence is secured between the stroke position of the plunger corresponding to the prescribed set sucking force and the spool position set by the output pressure corresponding to the prescribed set value of a voltage control valve part 2. Under such condition, a stroke position corresponding to the prescribed sucking force always exists in a prescribed stroke range. Thus each solenoid valve can absorb the error measured individually so as to secure the prescribed output pressure to a prescribed electric signal.
