流体设备
摘要：
本发明提供一种流体设备，能够抑制因波纹管的伸缩而在该波纹管的峰部产生裂缝的情况。上述流体设备具有波纹管，该波纹管构成为，为了使流体从吸入流路吸入且向排出流路排出，在轴心方向上能够伸缩，所述波纹管具有在所述轴心方向上交替地形成的峰部(17)以及谷部(18)、位于所述峰部与所述谷部之间且使两者连接的环状的侧面部(19)，所述轴心方向上的所述侧面部的壁厚(A)和与所述轴心方向垂直的方向上的所述峰部的轴心方向的中央部的壁厚(B)之间的比率(B/A)被设定为在1.3～1.8的范围内。
摘要（英）：

Provided is a fluid machine that can inhibit the formation of cracks in the crests of a bellows caused by expansion and contraction of the bellows. A fluid machine provided with a bellows configured to be capable of expanding and contracting in an axial direction in order to draw in a fluid from an intake channel and discharge the fluid to a discharge channel, wherein the bellows has crests (17) and troughs (18) formed alternatingly in the axial direction, and annular side walls (19) positioned between the crests and troughs and joining the crests and troughs together, the ratio (B/A) of the thickness (B) of the axially middle parts of the crests in a direction orthogonal to the axial direction relative to the thickness (A) of the side walls in the axial direction being set within a range of 1.3-1.8.
