Abstract
A relief valve mounted on a pump such as an oil pump, for preventing pressure abnormality by allowing fluid to escape when a discharge fluid pressure reaches a predetermined set value, wherein influx of oil sludge into the valve can be prevented. The relief valve comprises: a valve housing; and a guide inflow path which is in the same direction as a slide direction of a valve main body that slides along a valve guide path of the valve housing under a predetermined pressure and which provides communication between a discharge flow path and the valve guide path. The valve guide path is arranged so that a relief opening part thereof is closed downwardly by the valve main body. The valve guide path and the guide inflow path are arranged above an orthogonal cross section of the discharge flow path.
