SPRING ASSEMBLY FOR ACCUMULATOR AND ACCUMULATOR USING THE SPRING ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To facilitate assembly of an accumulator by applying recompression on a spring incorporated in an accumulator. SOLUTION: A spring assembly comprises a coil spring 1; a seat 2 make contact with the two end parts thereof: and a flexible regulation means 4 to apply a recompression on a coil spring by regulating a distance between sheets. A run-out regulating means 20 linked to the inner periphery of the cylinder hole 50 of an accumulator is arranged at the seat 2. A spring assembly in a curved state at an initial stage releases a cured state by pressing the seat 2 against the bottom part 53 of the cylinder hole through compression of the spring 1 and high compression of the spring 1 during operation of the accumulator is practicable through bending of the regulating means 4.
