流体设备
摘要：
本发明涉及一种流体设备(29A)，该流体设备(29A)具有壳体部(56)、外壳部(54)和涡盘(51、52)，其中，壳体部包括供处于高压的加热蒸汽的工作流体流入的吸入端口(55)，外壳部包括排出端口(53)，利用从吸入端口(55)吸入的工作流体对所述涡盘进行驱动。在此，将包括使吸入端口(55)与排出端口(53)连通的旁通路(81)和打开或关闭旁通路(81)的阀机构(83)的旁通部(80)夹持在壳体部(56)与外壳部(54)之间。在打开旁通路(81)后，工作流体绕过由涡盘部(51、52)构成的驱动部及自转阻止机构(60)等的滑动部进行循环，即便液相的工作流体流动，也能抑制滑动部中的润滑性下降。
摘要（英）：

The present invention relates to a fluid machine (29A) having: a casing section (56) provided with a suction port (55) into which an operating fluid having become a high-pressure heated vapor flows; a housing section (54) provided with a discharge port (53); and scroll sections (51, 52) driven by the operating fluid sucked from the suction port (55). A bypass section (80) is gripped between the casing section (56) and the housing section (54), and the bypass section (80) is provided with a bypass passage (81) for connecting the suction port (55) and the discharge port (53), and also with a valve mechanism (83) for opening and closing the bypass passage (81). When the bypass passage (81) is opened, the operating fluid circulates while bypassing both a drive section, which comprises the scroll sections (51, 52), and a slide section such as a rotation prevention mechanism (60). Even if an operating fluid in a liquid phase flows, the lubrication properties of slide section can be prevented from deteriorating.
