FIELD: machine building.SUBSTANCE: accumulator module for a hydraulic spring drive comprises a spring element (51) acting as an energy accumulator, and fluid medium to transfer the spring element (51) energy to the piston rod by a movable piston (30) of the accumulator to actuate a high voltage switch. The piston (30) is included in a leaktight casing (1) forming a high-pressure accumulating tank (13) for the fluid medium which is connected to the hydraulic system of the spring drive by two partial channels (11, 12) included in the tank (13) and a high-pressure channel (10) communicating with it. The piston (30) closes the partial channels (11, 12) starting from certain piston stroke length (s).EFFECT: optimisation of pressure dynamic characteristic in respect to the accumulator stroke length of the accumulator module of a spring drive.10 cl, 3 dwg |
