Abstract

The appts. for automatic bleeding and fluid admission for a hydraulic circuit comprises a pressure generator which is connected to hydraulic load components and which pressurises the hydraulic fluid supplied by a storage-feed tank of the pressure generator. At least one automatic bleed member is disposed immediately adjacent to a high point of the hydraulic circuit in at least one pipe element which connects this high point to the storage tank, in order to return clean air and opt. leaked hydraulic fluid to the storage tank. The bleed member may consist of a helical channel of preset length defined between the threads of a bolt and nut.
