Document Type and Number:
Japanese Patent JP7135614
Kind Code:
B2
Abstract:
To provide a technology that can prevent a valve element from being separated from a valve seat when a drive mechanism is not driven, in a flow control valve.SOLUTION: A flow control valve includes: a valve element; a rotation shaft; a drive mechanism for generating drive force for rotating the rotation shaft in a valve opening direction; a gear for transmitting the drive force to the rotation shaft; a coil spring for generating spring force for rotating the rotation shaft in a valve closing direction when the drive mechanism is not driven; and force generating mechanism parts 412, 351 for generating external force F for displacing the rotation shaft so as to bring the valve element close to a valve seat when the drive mechanism is not driven.SELECTED DRAWING: Figure 12
