Adjustable liq. flow divider for hydraulic systems - has two throttles whose cross=sections can be varied while retaining their sum constant

摘要

An adjustable liq. flow divider consists of a control valve with two outputs and two-possibly different-throttles at the input, followed by a control piston each, held in a middle position when pressures at the outputs are equal. In this position, the cross-sections of the outlets are also equal. When outlet pressures are different, the piston moves to a position in which the resultant pressure drop due to pressure difference at the two loads and to pressure drops in teh two throttles, is balanced on both sides. A device changes cross-sections of the throttles while maintaining the sum of their cross-sections constant.
