  • Valve opening-closing timing control device
    Patent number: 11162396
    Abstract: A valve opening-closing timing control device includes a valve case in which an inner space is formed in a direction along a rotational axis, and a valve unit accommodated in the inner space so as to be coaxial with the rotation axis and controlling fluid to and from an advance chamber and a retard chamber. The valve unit includes a check valve on an upstream side to which fluid is supplied. The check valve includes a valve seat in which a flow passage hole through which the fluid flows is formed, and a valve body including a closing portion that can close the flow passage hole. The valve seat includes a first projection portion to surround the flow passage hole. The check valve is closed by the closing portion contacting against the first projection portion, and is opened by the closing portion being separated from the first projection portion.
