    摘要: A method for diagnosing leaks in a hydraulic accumulator includes measuring the time required to discharge the hydraulic accumulator to determine an actual discharge duration. The method includes comparing the actual discharge duration to an expected discharge duration to generate a condition indicator. The condition indicator correlates to the presence or absence of a leak.

    摘要: The invention relates to a method for measuring the gas pressure in gas suspension or gas storage spheres (1), in particular, when in the assembled state in a motor vehicle and a device for application of the method. According to the invention, the checking of gas suspension or gas storage spheres my be simplified, whereby, for determination of the gas pressure, at least one temperature measurement of the shell of the sphere is taken, the actual value determined is compared with a set value thereof and the resulting difference is displayed. By means of the temperature measurement taken of the shell of the sphere, with reference to the stored measured data for the various operating states of the gas suspension or gas storage spheres (1), deviations from the set values may be determined in a simple and reproducible manner. The particular advantage of the invention is that the measurement may occur in the constructed vehicle and only the hydraulic pressure in the vehicle need be altered.

    摘要: An ultra-sound testing device for gas pressure accumulators is used to test a predeterminable set position that can be taken by a movable separating element (20) inside an accumulator (10) that can be filled with gas and connected to a fluid circuit. The separating element (20) has at least one testing body associated with a visible mark (34) which indicates the set position of the separating element (20), and on the basis of which an ultra-sound testing device provided for the respective testing body can be set on the accumulator (10). This testing device allows a plurality of accumulators of the same type to be tested for their predeterminable gas pressure set value, which corresponds to the gas pre-filling pressure, by means of a single hand apparatus. This kind of test is economical and achieves reliable results.
