摘要

The accumulator has an axial unit including an axial shouldered element (21) with a corner hole (211) extending axially from a raised top edge of the shouldered element towards bottom. An elevated part (212) is forcedly displaced for displacing a stop ball (134) in a removal direction of a stop flange (1231), so as to realize an opening of a vertical guiding hole (123) of a guiding channel (122) when the shouldered element is turned with respect to an envelope (11) until a predetermined position in which a transversal hole (2111) is maintained in communication with a vertical guiding groove.
