摘要:
A multi-stage rotary-type fluid machine may be configured as what is called a two-stage rotary expander, in which a refrigerant expands in an expansion chamber having a first discharge side space (115b) of a first cylinder (105), a second suction side space (116a) of a second cylinder (106), and a communication hole (104a) for allowing communication between the two spaces (115b, 116a). The first cylinder (105) and the second cylinder (106) are partitioned by an intermediate plate (104). The communication hole (104a) is formed so as to penetrate through the intermediate plate (104). The opening shape and location of the communication hole (104a) are set so that direct blow-through of the refrigerant from a suction port (105b) to a discharge port (106b) cannot occur at any rotation angle of a shaft (103).

An optical communication network node apparatus is provided that considerably reduces the node apparatus in scale, especially, a switch device in scale relative to increase in the number of wavelength multiplexes. With a routing operation on the basis of a wavelength at an intra-ring traffic step, light output from a plurality of demultiplexers is subjected to add/drop and routing processes and is directly or indirectly distributed to a plurality of multiplexers, and at an inter-ring traffic step (including a routing operation on the basis of a wavelength group), among lights output from a plurality of demultiplexers, light of another wavelength preliminarily set for inter-ring transmission and different from the light of the wavelength preliminarily set for the intra-ring transmission is subjected to the routing process, and, therefore, the node apparatus is considerably reduced to a smaller scale as compared to a node apparatus that achieves concatenation in a manner capable of routing lights of all the wavelengths to arbitrary optical rings.
