Method for actuating a hydraulic valve arrangement, and hydraulic valve arrangement

摘要

The disclosure relates to a method for actuating a hydraulic valve arrangement, having a hydraulic continuously adjustable valve and having a hydraulic switching valve for providing a variable opening cross section, wherein an opening cross section threshold value is predefined, wherein, above the opening cross section threshold value, the switching valve is placed into a defined switching position and only the continuously adjustable valve is actuated, and wherein, below the opening cross section threshold value, the continuously adjustable valve is placed into a defined switching position and only the switching valve is actuated.

1. A method for actuating a hydraulic valve arrangement configured to provide a variable opening cross section having a continuously adjustable valve and a switching valve, the method comprising:
coupling a pressure source of hydraulic fluid to the hydraulic valve arrangement; closing the continuously adjustable valve and actuating only the switching valve when the variable opening cross section is less than an opening cross section threshold value; and closing the switching valve and actuating only the continuously adjustable valve when the variable opening cross section is greater than the opening cross section threshold value.
