配气正时控制装置和具有该配气正时控制装置的内燃机制造方法及图纸

本发明专利技术提供一种能够在确保油路构造简易的同时确保链条盖的刚性的配气正时控制装置。安装有油路换向控制阀的阀室被一体地形成在链条盖上，另一方面与链条盖相互独立地设置具有油路的中间油路形成构件，该油路用于将自油泵供给至缸盖的油路开口的工作油供给到阀室中、并且将自阀室导出的工作油供给至相位改变机构的工作油室。然后，将中间油路形成构件安装在链条盖的链条室中，与链条盖一起将中间油路形成构件安装在缸盖上。结果，能够使油路的加工变得容易，并且，在将中间油路形成构件安装在链条盖上的情况下，也不用在链条盖上形成开口，能够确保链条盖的刚性。

Timing device for valve timing and internal combustion engine with said timing control device

The present invention provides a valve timing control device that ensures the simplicity of the oil circuit and ensures the rigidity of the chain cover. The oil valve chamber of the reversing control valve is integrally formed in the chain cover is installed on the other hand, with the chain cover independently arranged in the middle of the oil with an oil passage forming member, the oil pump to supply oil for self opening cylinder working oil supply to the valve chamber, and the valve chamber is derived from working oil supply to the phase change mechanism working oil chamber. Then, the intermediate oil passage forming member is arranged in the chain chamber of the chain cover, and the middle oil path forming component is arranged on the cylinder head together with the chain cover. As a result, it is possible to make the processing of the oil circuit easy, and in the case that the intermediate oil forming member is installed on the chain cover, the opening of the chain cover is not required, and the rigidity of the chain cover can be ensured.
