<P>PROBLEM TO BE SOLVED: To provide an oil pressure adjusting device for an internal combustion engine, capable of controlling an oil pressure in a good state while avoiding complexity and enlargement of a control device. <P>SOLUTION: An oil pressure adjusting device 16 for an internal combustion engine includes a valve body 168 moving in a casing 167 while receiving a predetermined oil pressure, and is configured to be able to discharge some of oil in a space 12 at a pressure receiving surface rear side of the valve body 168 partitioned by the valve body 168 and the casing 167 from a drain hole 11. At least some of the drain hole 11 is closed by the valve body 168 by the movement of the valve body 168 in a valve-opening direction, and is closed by the valve body 168 so that an open area of the drain hole 11 is smaller than that before the movement of the valve body 168. <P>COPYRIGHT: (C)2013,JPO&INPIT |
