    Abstract: PURPOSE:To drain oil in an exhaust oil chamber when oil is not being supplied to an accumulator chamber by installing a check valve, which passes oil only in the direction from the exhaust oil chamber to the accumulator chamber, in a division wall separating the exhaust oil chamber from the accumulator chamber. CONSTITUTION:Since oil in an accumulator chamber 1C is drained from an accumulator port 1D when oil in the accumulator chamber 1C is depressurized, an accumulator piston 2 is put in lower position by the action of a spring 3 and gravitation, and oil drained from a part in an upper position flows into an exhaust oil chamber 1B through an exhaust oil port 1E opening in the upper position of the exhaust oil chamber 1B. In the meantime, a check ball 4D in an enlarged part 4B of an orifice 4C is supported by a caulked part 4E because there is no pressure pressing it upward, and oil flowed in streams in the accumulator chamber 1C to be drained from the port 1D.

    Abstract: The invention relates to an accumulator module for a hydromechanical spring-loaded drive, wherein the spring-loaded drive is provided to actuate a high-voltage power switch (12), and wherein the accumulator module contains a pressure-tight housing (1), an accumulator piston (2) which protrudes into the housing (1) and is axially moveable in the housing (1), and a sealing cover (4) which seals the housing in an pressure-tight manner. In addition, at least one connecting channel (5, 6) is provided, which is introduced into the housing (1) for transporting a highly pressurised fluid present between the inner wall (7) of the housing and the head (3) of the accumulator piston to a high-pressure channel (11) of the spring-loaded drive, which channel is outside the housing. In order to increase the service life of the accumulator module, at least one pressure relief groove (8) is circumferentially applied to the head (3) of the accumulator piston.
