Document Type and Number:
Japanese Patent JP2014152917
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic valve which can suppress the leakage of fluid supplied to an output port from a supply port via a discharge port when making the supply port and the output port communicate with each other by a manual operation.SOLUTION: An electromagnetic valve comprises: a valving element 11 which contacts with and separates from a supply valve seat 36 formed at a flow-in port of fluid from a discharge port 17 in a valve chamber 32, and a discharge valve seat 21 formed at a flow-out port of the fluid to a discharge port 19 in the valve chamber 32, and switches communication states between and among the respective ports 17, 18 and 19 via the valve chamber 32; a fixed iron core 51 in which an excitation coil 54 is arranged at its outer periphery; a movable iron core 55 which approximates the fixed iron core 51 accompanying electricity-carrying to the excitation coil 54, and makes the valving element 11 abut on the discharge valve seat 21 by making the valving element separate from the supply valve seat 36; and a manual shaft 62 having a seal member 70 which can regulate the flow-out of the fluid from the valve chamber 32 through the discharge port 19, and pressing the movable iron core 55 to a direction in which the movable iron core approximates the fixed iron core 51 in a state that the seal member 70 regulates the flow-out of the fluid from the valve chamber 32.
