Title:
SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2019/135335
Kind Code:
A1
Abstract:
Provided is a solenoid valve which reduces the load applied to the valve body and the valve seat during valve closure to reduce the amount of wear on the valve body and valve seat, and thereby reduces change in the bleed flow rate, making it possible to prevent deterioration of the reheat dehumidification capacity. When not energized, the biasing force of a plunger spring 25 moves a plunger 27 in the valve opening direction, the valve shaft 20 engages with the plunger 27, and the valve body 21A is separated from the valve sheet 14A against the biasing force of the valve closing spring 23; when energized, the plunger 27 is moved in the valve closing direction against the biasing force of the plunger spring 25, and the biasing force of the valve closing spring 23 pushes the valve body 21A against the valve seat 14A.
