HYDRAULIC CONTROLLING DEVICE WITH AN OVERLOADING SIGNAL

摘要

The device is used in mobile equipment. It improves theenergy balance of hydraulic pieces of equipment on this type, anddepending on the magnitude of the loading signal it is possible toachieve effective distribution of the feed pump capacity. Muchlesser power is required for reswitching the distribution valve asa spring of lesser rigidity is used in its design, and theessential part of the power of the feed pump is used to controlthe operational hydraulics. The device includes a system ofadjustable throttles (25, 26 & 27) which interact with a controlpiston (15) of improved design and with a control bushing (16)fitted in the control element (14).5 claims, 6 figures
