摘要： A hydraulic machine includes an actuator, a tank (40), a directional control valve disposed between the actuator and the tank (40), and an adjustable return check valve (60) disposed between the directional control valve and the tank. The directional control valve includes an attachment actuator directional control valve (21) disposed between an attachment actuator (31) of the actuator and the tank and a swing actuator directional control valve (23) disposed between a swing actuator (33) of the actuator and the tank. The adjustable return check valve allows fluid to flow from the attachment actuator directional control valve toward the tank while applying the low back pressure but blocks a flow, and allows fluid to flow from the swing actuator directional control valve toward the tank while applying the high back pressure but blocks a reverse flow.

摘要： The present invention relates to a management unit (36) for managing material dumping in a dump area (26) using a plurality of autonomous dump machines (10, 38). Each autonomous dump machine (10, 38) comprises a sensor arrangement (22) adapted to determine at least one sensor arrangement parameter indicative of the environment adjacent to at least a portion of the autonomous dump machine (10, 38). The management unit (36) is adapted to: - establish a set of dump paths (24, 34, 44, 46), comprising at least one dump path (24), wherein each dump path (24, 34, 44, 46) extends in the dump area (26), and - issue an instruction to an autonomous dump machine (10) of the plurality of autonomous dump machines (10, 38) to follow a dump path (24) of the set of dump paths (24, 34, 44, 46) until the sensor arrangement parameter, determined by the sensor arrangement (22) of the autonomous dump machine (10), indicates that the autonomous dump machine (10) has reached a dumping position indicative of a dumping density of the dump area (26) being within a predetermined dumping density range.
