Abstract: The scroll-type compressor comprises a fixed scroll 320 and an orbiting scroll which are engaged with each other, a front housing 220 for accommodating the fixed scroll 320 and the orbiting scroll, and a rear housing 240 joined to the open end of the front housing 220. The fixed scroll 320 has the base plate 322 fitted into the front housing 220, and the flange 326 held at a joint surface between the front housing 220 and the rear housing 240. Additionally, at least one of the flange 326 of the fixed scroll 320 and the front housing 220 forms therein a recessed portion 326A or 220E which permits the fixed scroll 320 to be displaced in an axial direction toward the orbiting scroll due to a pressure difference acting on opposite surfaces of the base plate 322 of the fixed scroll 320.

Abstract: In an exhaust heat recovery device provided with a Rankine cycle device, a clutch for transmitting and interrupting power between an engine and the Rankine cycle device is released appropriately to prevent the Rankine cycle from becoming a load on the engine. An exhaust heat recovery device 1A includes a Rankine cycle device 2A, a power transmission mechanism 3A, and a control unit 4. The power transmission mechanism 3A has a clutch 31 and is capable of transmitting power between an engine 10 and the Rankine cycle device 2A when the clutch 31 is engaged. The control unit 4A controls the engagement and disengagement of the clutch 31 based on a first correlation value correlated with consumed power when the Rankine cycle device 2A is started, and a second correlation value correlated with consumed power of the Rankine cycle device 2A when the output of the Rankine cycle device 2A is negative during the operation of the Rankine cycle device 2A after the start-up.

Abstract: According to an embodiment, when a nozzle insertion member is detached from a powder container, an engaging portion and an engaged portion are disengaged from each other by resiliently displacing the engaging portion in a direction in which the engaging portion is disengaged from the engaged portion. Therefore, it is possible to reduce a stress applied to the powder container and the nozzle insertion member at the time of attachment and detachment of the nozzle insertion member. Consequently, it becomes possible to easily detach the nozzle insertion member from the powder container.

Abstract: A fluid machine (29A) including: a casing section (56) including a suction port (55); a housing section (54) including a discharge port (53); and scrolls (51, 52) driven by a working fluid suctioned from the suction port (55). In the fluid machine (29A), a bypass section (80), which includes a bypass passage (81) guiding the working fluid to the discharge port (53) while allowing the working fluid to bypass the scrolls (51, 52) and a valve mechanism (83) opening and closing the bypass passage (81), is supported between the casing section (56) and the housing section (54).

Abstract: A fluid machine (29A) including: a casing section (56) having a suction port (55) into which a working fluid that becomes a high pressure heated vapor flows; a housing section (54) having a discharge port (53); and a scroll section (51, 52) driven by the working fluid suctioned from the suction port (55). A bypass section (80) including: a bypass passage (81) allowing the suction port (55) to communicate with the discharge port (53); and a valve mechanism (83) opening and closing the bypass passage (81), is supported between the sections (56, 54). When the bypass passage (81) is opened, the working fluid is circulated while bypassing a driving section including the scroll section (51, 52) and a sliding section such as an anti-rotation mechanism (60). Therefore, even when the working fluid in a liquid phase flows, degradation of lubricity in the sliding section can be reduced.

Abstract: To provide a scroll-type expander having a relatively simple structure, small energy loss, and high durability and reliability. A pump-integrated expander 27 includes an expansion unit 50 configured as a scroll-type expander. In the expansion unit 50, a working fluid passage 51e extending from a suction port 51c open to the outside to an inlet 51d open to an expansion chamber 54 is formed in a base 51a of a fixed scroll 51. A working fluid supplied from the outside is guided to the expansion chamber 54 by the working fluid passage 51e. In order to receive a thrust force acting on an orbiting scroll 53 and to prevent the rotation of the orbiting scroll 53, a ball-coupling anti-rotation mechanism 56 using balls as rolling members is disposed between a stepped face 52c of an expander housing 52 and a base 53a of the orbiting scroll 53.
