Abstract

PURPOSE: To enable to attenuate and absorb an impulsive pressure produced at the time of closing a valve in a short while, by providing a check valve in a fluid passage extended on the upstream side of the valve body in a valve which is opened and closed through control of fluid pressure and magnetic force exerted to the valve body by a main magnetic pole.
CONSTITUTION: In the flow controlling solenoid valve shown in the drawing, a valve body 6 is moved away from a valve seat 5 and attracted to the top end face of a main magnetic pole 2 by magnetic force when the main magnetic pole 2 and side magnetic pole 5 are magnetized through the excitation of a coil 3. In this state, fluid in a passage 1 is passed to a nozzle hole 9 through a bypass passage 16. Here, one- way valve 17 serving as check valve is disposed in the passage extended on the upstream side of the valve body 6, i.e., in the fluid passage 1 formed in a main magnetic pole 2, and it is fixed in place by means of a guide sleeve 18 so that it may not come out. With such an arrangement, it is enabled to absorb impulsive pressure produced in the passage 1 due to the water hammering action and thus to prevent deterioration in the flow characteristics of the valve in case that the valve opening and closing cycle is increased.
