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： 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.
