Hydraulic pressure control for vehicle - uses regulator motor in conjunction with adjustable controllers for automatic or manual chassis suspension setting

摘要

A pressure control circuit (1) has an adjustable level element (4), a pump (2), a hydraulic fluid container (6), a pipe (7) and a valve (3). The circuit operates in dependence on pressure adjustment (3, 19) and control (18, 3, 19) devices. Pressure is controlled by a pressure switch (21) in series with an adjuster device (3, 19). ADVANTAGE - Limits pressure without additional connections on control.
