    摘要: A valve cover (1) for an l.C. engine (5) has a cover body (10) of an inverted trough-like configuration and a perimetric flange (20) surrounding its open bottom side. A seal receiving groove is formed in the bottom of the flange (20) and extends more than one full circuit around the open side. An elongated elastomeric seal strip (24) which is longer than the circumference of the cover body (10), as measured within the groove, is inserted into the groove so that opposite ends of the seal strip (24) are overlapped side-by-side and wherein the bottom of the seal strip (24) extends out of the groove to form a sealing ridge around the bottom of the flange (20). Through the provision of O-ring seals (30) on bolts (28) used for securing the cover body (10) to the engine (5), in conjunction with the seal strip (24), the valve cover (10) is able to minimize the production of engine vibration related noise. Additionally, an arrangement of partition walls, ribs, and columns is utilized to distribute loading applied by a row of top mounted bolts (28) uniformly throughout the periphery of the valve cover (10) and a pair of the partition walls are also utilized to form an Isolated chamber for a breather vent connection (42).
