METHOD OF REDUCTION OF MASS OF HYDRAULIC SYSTEM Russian patent published in 1998 - IPC

FIELD: aircraft and rocket hydraulic systems; hydraulic systems of road-building machines; mining engineering. SUBSTANCE: method is designed for hydraulic systems including power supply source in form of variable- capacity pump, consumers and mains connecting them. Mass of hydraulic system is reduced due to reduction of diameters of pipe lines. Static discharge characteristic of variable-capacity pump satisfies the following relationship: , where is pressure at pump outlet in modes at Q = Q_max, is pressure at pump outlet in modes at Q = 0,, Q_max - is maximum output of pump, Q is pump output, ΔP is total magnitude of losses of pressure in man from pump as far as consumers. EFFECT: improved response of actuating mechanisms at reduced mass of hydraulic system. 2 dwg
