20090189359 | Cylinder head gasket - A cylinder head gasket includes a first gasket base plate at a cylinder head side, a second gasket base plate at a cylinder block side, a shim that adjusts the gasket thickness, and a pressure increasing plate that increases the surface pressure at the side of periphery portions of the cylinders. In the first and second gasket base plates full beads are swollen at the side of periphery portions of cylinders, and half beads are swollen at a site outward of the full beads. The full beads of the first and second gasket base plates are formed so that top portions of the full beads face each other at positions that are opposite to each other in the up-down direction. The shim and the pressure increasing plate are sandwiched between the top portions. | 07-30-2009 |
20090235892 | CYLINDER HEAD COVER - A tubular valve casing formed of metal is molded with an outer shell portion formed of synthetic resin. A valve body is inserted into the valve casing through an opening formed at an end of the valve casing and incorporated in the valve casing. An annular projection is formed in the outer shell portion and projects toward the end surface of the valve casing corresponding to the opening. A seal ring is arranged between the projection and the valve body. | 09-24-2009 |

20090301427 | CYLINDER HEAD COVER - A cylinder head cover is formed by a synthetic resin outer shell, which is molded by inserting a metal valve case, which holds a oil control valve, in a mold. The valve case has a bolt fastening portion for fastening the valve case, together with the outer shell, to the cam cap. The valve fastening portion has a bolt insertion hole. The bolt fastening portion also has a flange that extends radially outward. The flange has through holes. The flange is embedded in the outer shell, and synthetic resin forming the outer shell fills the through holes. | 12-10-2009 |

20130126016 | OIL PAN INNER TANK VALVE STRUCTURE - In an oil pan inner tank valve structure, a disc-shaped float valve is arranged below a valve port that provides fluid communication between the inside and outside of a bottom wall of an inner tank, and a lower cover is arranged below the float valve. In addition, a center recess is depressed at a lower surface center of the float valve, and a lateral movement restricting pin is upright from the lower cover and is constantly engaged with the center recess by recess/protrusion engagement. The lower cover restricts a vertically movable range of the float valve. In addition, the lateral movement restricting pin restricts lateral movement of the float valve so that a top portion of an upper surface bulged portion vertically constantly faces an area inside a valve seat. | 05-23-2013 |
