Abstract
Official abstract text for this publication.
A metal bellows ( 110 ) for an accumulator ( 100 ) into which a hydraulic fluid is drawn in, has a bellows-shape in which ridge fold portions ( 110 a ) and valley fold portions ( 110 b ) are formed repeatedly with slope portions ( 110 c ) in between, wherein two of the slope portions ( 110 c ) that are adjacent to each other via a common ridge fold portion ( 110 a ) have: first slope portions ( 110 c 1 ) which extend from the common ridge fold portion ( 110 a ) and second slope portions ( 110 c 2 ) each of which extends from each of the first slope portions ( 110 c 1 ) such that a distance therebetween becomes much greater than the first slope portions ( 110 c 1 ) as the second slope portions ( 110 c 2 ) extend toward the adjacent valley fold portions ( 110 b ), wherein the first slope portion ( 110 c 1 ) and the second slope portion ( 110 c 2 ) are connected at an inflection point (P).
First claim
Opening claim text (preview).
1 . A metal bellows for an accumulator into which a hydraulic fluid or a pressure gas is drawn in, the metal bellows having a bellows-shape in which ridge fold portions and valley fold portions are formed repeatedly with slope portions in between, wherein two of the slope portions that are adjacent to each other via a common ridge fold portion have: first slope portions each of which extends from the common ridge fold portion such that a distance therebetween becomes greater as the first slope portions extend toward adjacent valley fold portions or such that the distance therebetween remains constant; and second slope portions each of which extends from each of the first slope portions extending from the common ridge fold portion such that a distance therebetween becomes much greater than the first slope portions as the second slope portions extend toward the adjacent valley fold portions, wherein the first slope portion and the second slope portion are such that cross sections thereof are connected at an inflection point. 2 . The metal bellows according to claim 1 , wherein the adjacent ridge fold portions make contact with each other when the metal bellows is in a maximally contracted state. 3 . The metal bellows according to claim 1 , wherein the adjacent slope portions do not make contact with each other when the metal bellows is in a maximally contracted state. 4 . The metal bellows according to claim 2 , wherein the adjacent slope portions do not make contact with each other when the metal bellows is in the maximally contracted state.
