Theory and application of π bridge hydraulic resistance networks

摘要

Pressure flow properties of seven basic π bridge hydraulic resistance networks are studied and the pressure flow characteristic curves are obtained by simulation, while the pressure gain and flow gain of π bridge are deduced. Half bridge hydraulic resistance is only a special case of π bridge network. The pressure control valve with the π bridge pilot control circuit has some pressure flow properties that the valve with half bridge pilot control circuit dosen's have.
