Definitions
- each storage space can be designed either as a diaphragm or piston spring storage or as a diaphragm spring storage.
- the check as to whether the individual accumulators are charged or not takes place, for example, as follows:
- the recesses for receiving the storage gas for the membrane accumulators are chosen so deep that a wall area remains between the adjacent outer surface of the upper housing part and the bottom surface of the recesses, so that It is thin-walled that when it is charged with pressurized fluid and the resulting compression of the storage gas, this wall area deforms elastically in a measurable manner.
- the invention takes advantage of the fact that when the individual energy stores are charged, certain wall parts of the housing block, the thickness of which must be dimensioned accordingly, deform due to the internal pressure, which can be detected, for example, by means of the strain gauges. This measuring principle can be used in the same way if the accumulators are designed as piston spring accumulators or as membrane spring accumulators.
- the three energy stores 21, 22 and 23 are so-called spring energy stores, in which a piston 42 is arranged in a cylinder space 43; on the upper side of the piston 42, the space 44, the fluid is located and in the opposite space 45 a spring 46 is accommodated, which serves as an energy storage spring and delivers the fluid from the space 44 to the piston-cylinder arrangement 12.
