SHOCK ABSORBER, EXPANSION BODY AND DRAINAGE SYSTEM
PROBLEM TO BE SOLVED: To provide a shock absorber for rapidly and stably easing pressure fluctuation in a drain pipe.SOLUTION: An shock absorber 100 includes an expansion body 120 capable of varying its capacity in accordance with increase and decrease of an internal pressure in a drain pipe. The expansion body 120 includes a hollow cylinder wall having one end opened and the other end closed, a plurality of outer grooves 124 cut along a circumferential direction of the cylinder wall from an outer surface, and a plurality of inner grooves 125 cut along the circumferential direction of the cylinder wall from an inner surface. The outer groove 124 and the inner groove 125 are alternately formed along an axial direction of the cylinder wall, and a groove width of the outer grooves 124 and a groove width of the inner grooves 125 are varied, and the expansion body expands or contracts in the axial direction.SELECTED DRAWING: Figure 8
【課題】排水管内の圧力変動を迅速且つ安定的に緩和する緩衝装置を提供する。【解決手段】緩衝装置１００は、排水管の内部圧力の増減に応じて容積が変動可能な伸縮体１２０を備える。伸縮体１２０は、一端が開放されたとともに他端が閉塞された中空の筒壁部と、筒壁部の周方向に沿って外面から切り込まれた複数の外溝部１２４と、筒壁部の周方向に沿って内面から切り込まれた複数の内溝部１２５と、を備える。外溝部１２４と内溝部１２５とが筒壁部の軸方向に交互に形成され、各外溝部１２４の溝幅及び各内溝部１２５の溝幅が変動して伸縮体が軸方向に伸縮する【選択図】図８
