摘要： The present invention relates to a pulsation suppression device which is interposingly used in a liquid transporting pipe through which a chemical liquid such as a surface washing liquid for washing an IC is transported by a reciprocal pump. The pulsation suppression device of the present invention has: a bellows which partitions the interior of the device body having a sealed container-like shape, into a liquid chamber and an gas chamber; an operating rod which is reciprocated in interlock relationship with the bellows; and an extension and contraction restricting mechanism which, when the bellows extends to a predetermined value, is contacted in parallel with a closed end face of the bellows, thereby restricting further extension of the bellows. Furthermore, the pulsation suppression device of the present invention has a guide for making the reciprocal operation of the operating rod coincident with the extension and contraction directions of the bellows. The guide is made of a low-friction resin material. According to the present invention, pulsation due to the discharge pressure of the transported liquid is absorbed and the amplitude of pulsation is suppressed to a low level. Moreover, the bellows used in the pulsation suppression device is prevented from being damaged, and the pulsation suppression function can be stabilized.
摘要翻译：脉动抑制装置技术领域本发明涉及一种脉冲抑制装置，其被插入到液体输送管中，通过该液体输送管中的诸如用于清洗IC的表面清洗液的化学液体通过往复泵输送。本发明的脉动抑制装置具有：将具有密封容器状的装置主体的内部分隔成液体室和气室的波纹管; 与波纹管互锁的操作杆; 以及延伸收缩限制机构，当波纹管延伸到预定值时，其与波纹管的封闭端面平行地接触，从而限制波纹管的进一步延伸。此外，本发明的脉动抑制装置具有使操作杆的往复运转与波纹管的伸缩方向一致的引导件。导轨由低摩擦树脂材料制成。根据本发明，由于输送液体的排出压力而产生的脉动被吸收，脉动幅度被抑制到低水平。此外，防止在脉动抑制装置中使用的波纹管被损坏，并且可以使脉动抑制功能稳定。

摘要： A connecting structure for an integration panel and a fluid device which, in order to promote integration of fluid pipes, can be further compactified is provided. In a concentric double flow path type connecting structure, an integration panel 1 and a valve 2 are connected to each other in a sealed state via inner and outer annular gaskets G1, G2 while pipe-like fluid passages 3a, 7 and annular fluid passages 4a, 8 are concentrically arranged. Annular projections 11, 21, 31, 41 are formed on fluid supply/discharge port portions 1A, 2A made of a fluororesin, and annular grooves 51, 61 are formed in the gaskets G1, G2 made of a fluororesin. A joined state where the annular projections and the annular grooves are fitted to each other to form a fitting sealing portion 10 is held by holding means I for attracting together the fluid supply/discharge port portions 1A, 2A and maintaining the attraction. The inner first gasket G1 is configured as a multifunctional intermediate gasket in which the inner peripheral face 54a functions also as the outer walls of the pipe-like fluid passages 3a, 7, and the outer peripheral face 55a functions also as the inner walls of the annular fluid passages 4a, 8.

摘要： A bellows that is extendingly and contractingly deformable in the axial direction is placed in a pump body and forms a liquid chamber inside the bellows. A suction portion and a discharge portion are formed in an inner bottom face of the pump body facing the liquid chamber. Liquid is sucked from the suction port into the liquid chamber by extension of the bellows, and the liquid in the liquid chamber is discharged from the discharge portion by contraction of the bellows. The extending and contracting portion of the bellows which is configured by forming ridge-like folds and valley-like folds in a vertically alternate and continuous manner is formed into a shape in which the lower one of upper and lower lamella portions of each of the ridge-like folds, or the lower lamella portion is inclined downwardly toward the axis defining the axial direction, not only in an extending state but also in a contracting state. Even in the case where liquid containing a sedimenting material such as slurry is used, therefore, the sedimenting material can be prevented from sedimenting and stagnating in the extending and contracting portion of the bellows.
摘要翻译：在轴向方向上可伸缩地变形的波纹管被放置在泵体内并在波纹管内部形成液体室。抽吸部分和排出部分形成在泵体的面向液体室的内底面中。通过波纹管的延伸将液体从吸入口吸入液体室，液体室中的液体通过波纹管的收缩从排出部排出。通过以垂直交替连续的方式形成脊状折叠和谷状折叠而构成的波纹管的伸缩部分形成为每个脊的上部和下部薄片部分的下部的一个形状或者下薄片部分朝向限定轴向方向的轴向下倾斜，不仅处于延伸状态而且处于收缩状态。因此，即使在使用含有浆料等沉降物的液体的情况下，也能够防止沉积物在波纹管的伸缩部分的沉降和滞留。
