METHOD FOR TESTING THE FUNCTION OF A HYDRAULIC VALVE AND A TEST BENCH FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for testing the function of a hydraulic valve and to a test bench for carrying out said method. The method is characterised in that a pressurised gaseous medium is used as the test medium. According to the invention, volumetric flow characteristic values or volumetric flow characteristic curves (61) are determined in accordance with the time or the valve stroke and are subsequently compared with limiting value characteristic curves (63).
