摘要： PROBLEM TO BE SOLVED: To provide a piping waterproof connection structure enabling sufficient waterproofing of waterdrops scattered in intake air of an internal combustion engine and having high flexibility of a mounting position of piping of an intake air sensor, etc.
SOLUTION: In the waterproof connection structure, a slotted opening part 14a comprising bent lower edge and a linear upper edge is provided on a partition wall 12. This prevents generation of a water screen on the whole area of the opening part 14a, so as to successfully maintain pressure transmission to an intake pressure sensor. Since the water screen is not formed on the whole area, waterdrops flied from the opening part 14a are easily discharged from the opening part 14a to the side of a surge tank. Since a connection space 14 is expanded with respect to the opening part 14a and a tip opening on the side of a pressure delivery pipe 16a, water entered to inside of the connection space 14 hardly narrows or clogs the opening part 14a and the tip opening. Therefore, this can achieve sufficient waterproofing. Moreover, since only the connection space 14, the partition wall 12 and the opening 14a are provided in a connection portion of the pressure delivery pipe 16a, this structure extremely enhances the degree of freedom of the mounting position to the surge tank.

摘要翻译：要解决的问题：提供一种能够对分散在内燃机的进气中的水滴进行充分防水并且具有高进气传感器的配管安装位置的高柔性的管道防水连接结构。解决方案：在防水连接结构中，在分隔壁12上设置包括弯曲的下边缘和直线上边缘的开槽部分14a，从而防止在开口部14a的整个区域上产生水屏，从而成功地保持对进气压力传感器的压力传递。由于在整个区域上没有形成水屏，因此从开口部14a排出的水滴容易从开口部14a排出到缓冲罐侧。由于连接空间14相对于开口部14a膨胀并且在压力输送管16a一侧的顶端开口，所以进入连接空间14内部的水难以使开口部14a和前端开口变窄或堵塞。因此，可以实现充分的防水。此外，由于只有连接空间14，分隔壁12和开口14a设置在压力输送管16a的连接部分中，所以这种结构极大地提高了安装位置到缓冲罐的自由度。版权所有（C）2009，JPO＆INPIT
