COOLING LIQUID CONTROL VALVE

摘要

PROBLEM TO BE SOLVED: To provide a cooling liquid control valve that suppresses blockage of a flow-rate hole of a valving element due to a foreign matter contained in a fluid.SOLUTION: The cooling liquid control valve includes: the valving element 11 and a valve seat 14 provided in a fluid flow passage, each including a magnetic material 12 so that they abut on each other and are separated apart from each other to control circulation of fluid; an energization member 17 for energizing the valving element 11 on a side of the valve seat 14; a solenoid 2 for causing the valving element 11 and the valve seat 14 to abut on each other by generating magnetic force with electrification thereto; and a control part for controlling electrification to the solenoid 2. The valving element 11 includes a circulation hole 11a for circulating the fluid therethrough while the valving element 11 and the valve seat 14 abut on each other. The cooling liquid control valve includes a blockage suppressing mechanism 40 for suppressing blockage of the circulation hole 11a due to the foreign matter contained in the fluid.SELECTED DRAWING: Figure 2
