<p>A crusher so designed that a pair of crushing members are supported for titling on a frame journaled for turning in a bracket attached to the arm or the like of an industrial vehicle, the crushing members being tilted for crushing by a fluid pressure cylinder in directions opposite to opposed directions, wherein incorporated in a rotor mounted on the journal in a space above the fluid pressure cylinder is a speed-increasing valve for increasing the tilting speed by causing the fluid in one cylinder chamber of the fluid pressure cylinder from which the fluid is discharged to flow into the other cylinder chamber of the fluid pressure cylinder into which the fluid flows when the crushing members are tilted in the opposed directions. Thereby, the speed-increasing valve can be incorporated without spoiling the speed-increasing effect of the speed-increasing valve and without changing the construction of the crusher itself.</p> |
