Abstract
The invention relates to a high-pressure liquid installation with a pressurized water generator (10) to which a spraying device (42) is connected, while an adjustable pressure-limiting valve (14) is arranged between the pressurized water generator (10) and the spraying device (42). The pressure-limiting valve (14) is adjustable in its pressure by remote operation by electrical signals which can be generated by electrical control elements (56, 58), while a delay device (40) may be provided for surge-free pressure adjustment.
Claims14
High-pressure liquid installation with a pressurized liquid generator to which a spraying device is connected, a valve between the pressurized liquid generator and the spraying devce which can be opened and closed by remote operation by a switch in order to feed the liquid to the spraying device or return the same to the region of the suction side of the pressurized liquid generator, said valve being constructed as an adjustable pressure-limiting valve and adjustable in its pressure by remote operation, electrical control elements arranged in association with the spraying device and operable to adjust said pressure limiting valve, a delay device for surge-free pressure adjustment associated with the valve, and said pressure limiting valve having at least two pressure stages which are selectable by actuation of said control elements and preadjustable in conformity with required pressure levels, and a control device for preadjusting said required pressure levels.
