Abstract (en)
[origin: EP1837529A1] The device has a regulation pump connected with an outlet valve, a safety valve and a loading pressure line sector at operation selecting-path control valves (4, 5). A 3/2-way control valve (29) is shifted between a switching position for operation with a constant supply primary pressure from the pump and another position for operation with a variable supply pressure from the pump. The valve (29) is shifted hydraulically and pressure-dependently against a spring (30) that defines the position for operation with the constant pressure in the position for operation with the variable pressure.
