    Abstract: A power element has a closed space provided between a first diaphragm and a second diaphragm. An interposing member is interposed between the first diaphragm and the second diaphragm. Accordingly, a size of the closed space can be optionally determined in accordance with a shape such as a thickness of the interposing member. Therefore, limitations on the size of the closed space due to a shape of the first diaphragm and the second diaphragm can be reduced. Accordingly, limitations on the size of a fluid enclosing space due to a shape of a diagram can be reduced.

    Abstract translation: 功率元件具有设置在第一膜片和第二膜片之间的封闭空间。 介于第一隔膜和第二隔膜之间的插入件。 因此，封闭空间的尺寸可以根据诸如介入构件的厚度的形状任意地确定。 因此，可以减少由于第一膜片和第二膜片的形状而导致的封闭空间尺寸的限制。 因此，可以减少由于图形的限制对流体封闭空间的尺寸。

    Abstract: An ejector includes a nozzle, a needle and a body. The nozzle reduces a pressure of a fluid and discharges the fluid as an injected fluid from a fluid injection port. The body includes a fluid suction port and a pressure increasing portion. The fluid suction port draws, as a suction fluid, a fluid from an outside of the body by using a suction force generated by the injected fluid. The pressure increasing portion increases a pressure of a mixture of the injected fluid and the suction fluid. The nozzle includes a throat portion and a nozzle-side tapered portion. The throat portion reduces a passage cross-sectional area of the fluid passage to be smallest in the fluid passage at the throat portion. The nozzle-side tapered portion expands the passage cross-sectional area of the fluid passage toward the downstream side in the flow direction of the fluid. In an axial cross section, an injection-flow spread angle formed on the downstream side in the flow direction of the fluid between a central axis and a tangent line of an injection-flow center line at the fluid injection port is 0° or greater.

    Abstract: When an ejector having a variable nozzle and a variable throttle mechanism are integrated together as an ejector module, a nozzle-side central axis CL1 and a decompression-side driving mechanism have a twisted positional relationship, if the nozzle-side central axis CL1 is defined as a central axis of a nozzle-side driving mechanism in a displacement direction in which the nozzle-side driving mechanism of the ejector having the variable nozzle displaces a needle valve, and the decompression-side central axis CL2 is defined as a central axis of a decompression-side driving mechanism in a displacement direction in which the decompression-side driving mechanism of the variable throttle mechanism displaces a throttle valve. When viewed from the central axis direction of one of the nozzle-side central axis CL1 and the decompression-side central axis CL2, a driving portion corresponding to the one central axis is disposed to overlap with the other central axis.
