摘要： A pressure-receiving face plate 29 is mounted on one end face of a piston 12, and a support member 26 is raised on the end face of the piston 12. Disposed on the support member 26 with an allowance are, from the pressure-receiving faceplate 29 respectively, a disk spring 27, a plate 25, and a plunger 28. A flange 26a prevents these members from slipping off the support member 26. When the piston 12 approaches a stroke end, the plunger 28 is inserted in an oil passage 20b and applies a cushioning effect to the piston 12. In addition, a gap between the pressure-receiving faceplate 29 and the plate 25 brought into contact with a cylinder bottom 17 becomes narrow, and produces a squeeze effect such that oil escapes from the narrow gap. This makes it possible to provide a hydraulic cylinder that produces a sufficient impact force at the stroke end of the piston and also reduces noise emitted by the impact force, without increasing a length of the hydraulic cylinder.
摘要翻译：压力接收面板29安装在活塞12的一个端面上，并且支撑构件26在活塞12的端面上升高。从压力接收部分别为盘片29，盘簧27，板25和柱塞28.凸缘26a防止这些构件从支撑构件26滑落。当活塞12接近行程端时，柱塞28插入油路并且对活塞12施加缓冲效果。此外，受压面板29与与缸底17接触的板25之间的间隙变窄，产生挤压效果，使得油从窄的间隙。这使得可以提供在活塞的行程端产生足够的冲击力的液压缸，并且还可以减小冲击力产生的噪音，而不增加液压缸的长度。

摘要： An engine compartment cover for a work machine includes left and right-hand side covers for covering the sides of an engine, and a hood for covering the top of the engine. The engine compartment cover serves to enclose the engine and demarcate an engine compartment and is capable of suppressing the noise at the operator's ear level caused by the engine operating noise passing through the engine compartment cover as far as possible, whereby the level of quietness in the operator cab can be improved. In the engine compartment cover for a work machine, the hood has a box-type structure including an exterior top plate, side plates surrounding the whole perimeter of the exterior top plate, and a bottom plate opposed to the exterior top plate, and air inlet holes are provided in the side plates only, whilst an air outlet hole is provided in the bottom plate only, in such a manner that external air is drawn into the interior of the hood via the air inlet holes and air is introduced into the engine compartment via the air outlet hole.
