Abstract
A gyratory crusher hydraulic pressure relief valve includes a hydraulic fluid vestibule arranged to be fluidly connected to a hydraulic fluid space. A logic element is arranged to dump hydraulic fluid from the hydraulic fluid space, which includes a plunger having a first plunger surface and a second plunger surface, and a control pipe arranged for fluidly connecting the second plunger surface to the hydraulic fluid vestibule. A supply orifice restricts the flow of hydraulic fluid from the vestibule towards the second plunger surface to make the time TC it takes for the logic element to switch from open position to closed position exceed the time TF it takes for a closed side setting position of the crusher to make one full round.
