Abstract: A valve timing control apparatus includes a check valve, a filter, and a filter holding body. The check valve is placed between a camshaft and a vane rotor. The filter is placed between the camshaft and the check valve. The filter holding body includes a plurality of metal plates, which are stacked one after another. Two metal plates, which serve as enlarged space forming plates, are placed adjacent to the filter on one side of the filter where the camshaft is placed while each of the two metal plates includes enlarged through holes. A metal plate, which serves as an enlarged space forming plate, is placed adjacent to the filter on another side of the filter and includes enlarged through holes. A flow passage cross-sectional area of each enlarged through hole is larger than a flow passage cross-sectional area of a supply oil passage.

Abstract: A sealing member is supported by a holding surface of a vane rotor and slides on a sealing surface formed by an inner surface of a housing rotor, so as to seal an advancing chamber and a retarding chamber from each other. The sealing member has a pressure-receiving surface and a diffuser surface. The pressure-receiving surface receives pressure of working fluid from a working chamber in a direction to the sealing surface. The diffuser surface forms a sealing gap between the diffuser surface and the sealing surface, so that the sealing surface becomes larger as the sealing surface is more separated from the working chamber in a circumferential direction. The sealing member has a deformable portion forming the pressure-receiving surface and the diffuser surface. The deformable portion is elastically deformed, so that the diffuser surface is more strongly pushed to the sealing surface, when the pressure of the working fluid is increased.

Abstract translation: 密封构件由叶片转子的保持面支撑，并在由壳体转子的内表面形成的密封面上滑动，以将前进室和减速室彼此密封。 密封构件具有压力接收表面和扩散器表面。 压力接收表面从工作室沿着朝向密封表面的方向承受工作流体的压力。 扩散器表面在扩散器表面和密封表面之间形成密封间隙，使得密封表面随着密封表面在圆周方向上与工作室更分离而变大。 密封构件具有形成压力接收表面和扩散器表面的可变形部分。 可变形部分弹性变形，从而当工作流体的压力增加时，扩散器表面被更强地推到密封表面。
