    FIG. 1 shows a hydropneumatic accumulator, equipped with a sensor for limiting the position of the piston and a control device, a longitudinal section; in fig. 2 and 3 is the same, with various embodiments of the sensor for limiting the position of the piston and installing the control device, a partial section.
    The hydropneumatic accumulator includes a housing 1, two covers 2 and 3 a piston installed to form a hydraulic cavity 5 and a gas cavity 6, a sensor 7 with a movable member 8, a flexible element 9, a lever 10 mounted on a fork 11 movably, an interrupter 12 and a spring 13.
    The battery works as follows.
    To check the operation of the sensor 7, which is a gas shortage detector, it is sufficient to reduce the pressure in the hydraulic cavity 5 to such a value that the piston under the gas pressure will move by an amount that is greater than the normal lower position of the piston. In this case, the flexible element 9 is tensioned and through the lever 10 actuates the movable member 8 of the sensor 7, which closes the interrupter 12. The interrupter 12 controls the electrical circuit warning of gas shortage. The spring 13 returns the mobile unit 8 to its original position after checking the sensor 7 Accumulators (Fig. 2 and 3) work in the same way, the difference lies in the performance of the sensor 7 and the device controlled by this sensor.
    Due to the use of the monitoring device in the accumulators of the monitoring device, the sensor 7 can be performed without changing the pressure in the gas cavity and without dismantling the battery.
