摘要： A removable exhaust pipe cover for placement over an exhaust pipe opening of a non-running internal combustion engine for excluding water and debris from entering the pipe. The cover is an elongated tubular member of water repellant material which is preferably flexible to a degree, the flexibility being for allowing constricting and sealing against the pipe when in use, and for compact folded or collapsed storage of the cover when not in use. The tubular cover has a closed top end, an oppositely disposed open bottom end, and an annular sidewall extending between the two ends. The bottom open end of the cover, in at least one embodiment, has a elasticized gathered hem which holds the cover tightly closed about the exhaust pipe with the closed top end and upper portion of the sidewall covering and thus closing the open end of the pipe when installed. An elongated telescopic pole is provided for engaging and positioning the cover over an exhaust pipe terminal end, particularly an end which is high above the ground. The pole and cover include cooperative structuring for allowing use of the pole to remove the cover from the exhaust pipe end when the internal combustion engine is to be operated.
摘要翻译：一种可拆卸的排气管盖，用于放置在不运行的内燃机的排气管开口上，以排除水和碎屑进入管道。盖是一种延伸疏水材料的细长管状构件，其优选地柔性到一定程度，该柔性用于在使用时允许对管道进行收缩和密封，并且在不使用时对盖进行紧凑折叠或倒塌储存。管状盖具有封闭的顶端，相对设置的敞开的底端以及在两端之间延伸的环形侧壁。在至少一个实施例中，盖的底部开口端具有弹性聚集的折边，其围绕排气管保持封闭，封闭的顶端和侧壁的上部覆盖，因此封闭管的开口端安装时。提供了一个细长的伸缩杆，用于在覆盖排气管末端的位置，特别是高于地面的一端接合和定位盖。杆和盖包括协同结构，用于当内燃机要被操作时允许使用杆从排气管端移除盖。
