Abstract: An oil control valve has a housing and a spool valve that is arranged in the housing and is movable in the axial direction. The movement range of the spool valve includes a first area and a second area. In the first area, a port that is connected to a lock mechanism opens to prevent the movement of a variable valve timing mechanism through drainage of oil from the lock mechanism. In the second area, oil is supplied and drained to and from the variable valve timing mechanism through a passage inside the spool valve. The first area exists at a position separated from the second area in the movement range.
Abstract translation: 油控阀具有壳体和滑阀，其设置在壳体中并且可沿轴向移动。 滑阀的运动范围包括第一区域和第二区域。 在第一区域中，连接到锁定机构的端口打开以防止可变气门正时机构通过从锁定机构排出油而移动。 在第二区域中，油通过滑阀内的通道供给并从可变气门正时机构排出。 第一区域存在于与移动范围中的第二区域分离的位置。
