燃料喷枪的防旋转装置
摘要：
本发明涉及一种燃料喷枪(100)的防旋转装置(120)，所述喷枪(100)能够布置在孔(102)中，所述孔穿过气缸的气缸盖(104)从入口开口(116)延伸直到为了接收燃料喷射器(110)而设置的孔(108)，所述喷枪(100)适于允许高压燃料从所述喷枪的入口开口循环直到所述喷枪(100)的与所述燃料喷射器(110)的所述入口开口(126)接合的出口开口(124)，所述燃料喷枪(100)包括旨在拧紧到所述孔(102)中的入口开口(116)中的螺母(112)以及在所述螺母(112)与所述喷射器(110)之间被压缩的管状构件(118)，所述喷枪(100)还包括能防止当所述螺母(112)被拧紧时所述管状构件(118)的旋转的所述防旋转装置(120)，其特征在于，所述防旋转装置(120)是在所述螺母(112)开始旋转时就变形的弹性元件，以便被锁定在所述管状构件(118)与所述孔(102)的内壁之间，由此防止所述管状构件(118)的旋转。
摘要（英）：

The invention relates to an anti-rotation device of a fuel lance arranged in a bore extending through a cylinder head of a cylinder head from an intake opening until a hole provided for receiving a fuel injector, the lance allowing high-pressure fuel to circulate from an intake opening of the lance until the outlet opening of the lance engaging with the intake opening of the fuel injector, the fuel lance including a nut for being screwed into the intake opening of the bore and a tubular member compressed between the nut and the injector, the lance also including the anti-rotation device. The anti-rotation device is a resilient element which is deformed by rotation of the nut, such as to be blocked between the tubular member and an inner wall of the bore, and thus prevent rotation of the tubular member when the nut is screwed.
