Abstract
An accumulator loading valve is provided which is adapted for elevated pressures, which requires but little space, and which has a pump connection (1), a reservoir connection (20), a priority valve (7) between the consumer connection and the accumulator connection, and a pilot valve (4) being controlled by the accumulator pressure. The improvement is that the operating piston of the two-position pilot valve (4) is prestressed by a spring (28) having a constant spring rate and that the cross section of the valve inlet (19) is smaller than the cross section of the valve discharge (20).
