Flow passage partition structure and fluid control valve

A fluid control valve of a valve timing control apparatus,

• the valve timing control apparatus comprising:
• a drive side rotary member rotating synchronously with a crankshaft of an internal combustion engine;
• a driven side rotary member arranged coaxially with the drive side rotary member and rotating synchronously with a camshaft of the internal combustion engine;
• a fluid pressure chamber divided into an advanced angle chamber and a retarded angle chamber;
• and
• a bolt arranged by insertion in the driven side rotary member to be coaxial with a rotary axis of the driven side rotary member and connecting the driven side rotary member and the camshaft to each other,
• the fluid control valve including a passage partition structure comprising:
• a flow passage member including a flow passage space portion through which fluid flows;
• and
• a partition member partitioning the flow passage space portion into a first flow passage and a second flow passage;
• the partition member including:
• a first plate being inserted into the flow passage space portion from one opening end portion of the flow passage member, and being in contact with a step portion provided at a boundary between the first flow passage and the second flow passage at an innermost side in an insertion direction of the first plate;
• a second plate being inserted into the flow passage space portion after the first plate is inserted into the flow passage space portion, the second plate being in contact with the first plate in such a manner that the second plate overlaps the first plate in a state where the second plate is press-fitted in an inner circumferential surface of the flow passage space portion;
• the first plate including an outer circumferential surface that is out of contact with the inner circumferential surface of the flow passage space portion;
• and
• the first plate, the second plate, and the inner circumferential surface of the flow passage space portion forming a space portion that corresponds to a foreign material storage portion, wherein
• the first plate and the second plate are inserted in a hole portion provided in a direction of the rotary axis at the bolt, and the first flow passage and the second flow passage are provided at the hole portion, and
• the fluid control valve supplies and discharges working fluid relative to the fluid pressure chamber.
