摘要： A scroll-type fluid machine comprises a stationary scroll member, an orbiting scroll member, a rotation-prevention mechanism for the orbiting scroll member, and a casting accommodating therein both members and the mechanism. The involute angle of a terminal end of a wrap of the orbiting scroll member is selected to be less than that of the wrap of the stationary scroll member by an angle which ranges between 60.degree. and 120.degree., preferably, about 90.degree., thereby reducing a level of force applied to the rotation-prevention mechanism which prevents the orbiting scroll member from rotating about its own axis.

摘要： A screw vacuum pump including a plurality of casings and a pair of rotors defining a plurality of working chambers. The working chambers are constituted by working chambers whose volumes undergo a change as the rotors rotate, and working chambers whose volumes undergo substantially no change as the rotors rotate. The screw vacuum pump is capable of achieving pressure of 10.sup.-1 to 10.sup.-4 Torr or a low or medium vacuum by means of a single pump operating in a single stage.

摘要： An air-conditioner system having a compressor, a plurality of heat exchangers for heating or cooling the air in a room, a radiator for transferring heat energy of refrigerant outside of the room, a plurality of orifices, a manifold with a main port and a plurality of sub-ports, flow direction control multi-port valves directing the flow of the refrigerant from the compressor to the main port and not from the main port to the compressor when at least one of the heat-exchangers is heating the room. The refrigerant does not flow from the compressor to the radiator when at least one of the heat exchangers is heating and none of the heat exchangers is cooling. Also, it does not flow from the compressor to the main port but flows instead from the compressor to the radiator and from the main port to the compressor when none of the heat exchangers is heating and at least one of the heat exchangers is cooling. The system also employs a plurality of valve pairs each of which having a first valve and second valve such that the first valve opens (closes) when the second valve closes (opens). The first valves are arranged for providing flow of refrigerant to the inlet of the compressor from the heat exchangers and the second valves provide flow of refrigerant from the outlet port of the compressor to the respective heat exchanger first ports via the sub-ports of the manifold.
摘要翻译：一种具有压缩机，多个用于加热或冷却房间中的空气的热交换器的空调系统，用于将制冷剂外部的热能传递到室外的散热器，多个孔，具有主端口的歧管和多个子端口，流动方向控制多端口阀，当至少一个热交换器加热房间时，将制冷剂从压缩机流向主端口，而不是从主端口流向压缩机。当至少一个热交换器加热并且没有热交换器冷却时，制冷剂不会从压缩机流到散热器。此外，当没有热交换器被加热并且至少一个热交换器被冷却时，其不从压缩机流向主端口，而是从压缩机流到散热器，并且从主端口流到压缩机。该系统还采用多个阀对，每个阀对具有第一阀和第二阀，使得当第二阀关闭（打开）时第一阀打开（关闭）。第一阀被布置成用于从热交换器向制冷剂的入口提供制冷剂流，并且第二阀提供制冷剂从压缩机的出口流到相应的热交换器第一端口，经由歧管的子端口。

摘要： A refrigerating system having a refrigerating cycle constructed by connecting an accumulator, a refrigerant compressor, a four-way valve, an outdoor unit heat exchanger, an outdoor unit expander, a receiver, an indoor unit expander and an indoor unit heat exchanger sequentially by pipes. Normally, excessive refrigerant is stored in the receiver and when it becomes necessary to raise a ratio of lower boiling point refrigerants, a flow amount of the refrigerant is decreased by restricting the outdoor unit expander during the cooling operation or by restricting the indoor unit expander during the heating operation to move the excessive refrigerant within the receiver to the accumulator. Thereby, the composition of the refrigerant circulating within the refrigerating system using non-azeotrophic refrigerant mixtures may be changed without using a complicated system structure or control method thereof and the capacity of the refrigerating cycle may be changed.
