摘要： An improved refrigerant recovery method and apparatus by which a refrigerant charged in a refrigerator is transferred into a refrigerant tank are disclosed. The apparatus is adapted to discharge almost all the refrigerant gas from the refrigerator and purge non-condensible gases from a safety valve to the atmosphere with little refrigerant gas accompanying the non-condensible gases. There are provided a vacuum pump at the upstream side of a line connected between the refrigerator and a liquid separator, and a compressor at the downstream side thereof, the vacuum pump and compressor being connected in series with each other. The vacuum pump is intended to nearly zero the pressure of the remaining refrigerant gas in the refrigerator and the compressor is to give the liquid separator a desired internal pressure, thereby minimizing the amount of refrigerant gas purged along with the non-condensible gases to the atmosphere. Also a bypass valve is provided to bypass the vacuum pump. By opening the bypass valve to activate the compressor independently with the vacuum pump put out of operation to circulate the refrigerant liquid accumulating in the lower portion of the liquid separator to the refrigerator, it is possible to purge the non-condensible gases to the atmosphere during operation of the refrigerator.
摘要翻译：公开了一种改进的制冷剂回收方法和装置，其中将装在冰箱中的制冷剂转移到制冷剂罐中。该装置适于从冰箱排出几乎所有的制冷剂气体，并且将不可冷凝气体从安全阀排放到大气中，伴随着不可冷凝气体的少量制冷剂气体。在连接在冰箱和液体分离器之间的管线的上游侧设有真空泵，在其下游侧设置有真空泵和压缩机彼此串联连接的真空泵。真空泵几乎将冰箱中剩余的制冷剂气体的压力几乎归零，并且压缩机将使液体分离器产生所需的内部压力，从而最小化与不可冷凝气体一起吹送到大气中的制冷剂气体的量。还提供旁通阀以绕过真空泵。通过打开旁通阀以独立地启动压缩机，使真空泵停止运行，使积液在液体分离器的下部的制冷剂液体循环到冰箱，可以将不可冷凝的气体吹扫到大气中操作冰箱。

摘要： An apparatus for controlling the operation of a fluid pressure raising system having a motor and a centrifugal fluid machine adapted to be driven by the motor. The apparatus has an overdrive gear disposed between the motor, which is typically an electric motor suited for the commercially available electric power, and the centrifugal fluid machine. The overdrive gear consists of two gear trains or pairs having different overdrive ratios, each consisting of a gear and a pinion meshing with the gear, and a clutch adapted to selectively switch over the gear pair taking part in the torque transmission between the output shaft of the motor and the impeller shaft of the centrifugal fluid machine, from one gear pair to the other gear pair and vice versa. Thus, the overdrive gear can transmit the power of the motor to the impeller at two different overdrive ratios. The clutch is adapted to be actuated in response to a signal representative of an external condition of the fluid pressure raising system, which signal is delivered by a detector.

摘要： In an absorption type chiller heater, a generator is heated in order to heat a refrigerant-mixed solution to generate refrigerant vapor. This heating is generally carried out by causing high-temperature combustion gas to flow in contact with heat transfer fins, which are provided on the periphery of the generator. The aforesaid burner uses a burner of liquid-fuel combustion structure to produce a longer flame as compared to that of a gas burner. The extremity of the lengthened flame coming into contact with the heat transfer fins can cause problems such that the fins are locally overheated to burn out. In this view, the present invention arranges a flame buffer plate between the liquid fuel burner and the heat transfer fins and provides a curved flame channel. This forms a curved flame, whereby the flame, despite of its great length, is kept from its extremity coming into contact with the heat transfer fins. Besides, the flame channel, even if long, is curved to prevent larger outer dimensions of the entire chiller heater.

摘要： In a turbo-refrigerator apparatus provided with a compressor in the form of a turbocompressor, a speed increasing gear system capable of switching from one speed increase ratio to another at least in two stages is located between the turbocompressor and an electric motor, so that a speed increase ratio suitable for the conditions of outdoor air can be selected to operate the apparatus with high efficiency. Housings of the turbocompressor, electric motor and speed increasing gear system are connected together in such a manner that a shaft supporting an impeller of the turbocompressor, an output shaft of the electric motor and shafts of the speed increasing gear system are located within the respective housings to render the apparatus hermetic to avoid extension of the rotary shafts through the housings, thereby avoiding leak of the working fluid of the turborefrigerator apparatus to outside.

摘要： In a multistage speed change gear system including a plurality of gears selectively interconnecting an input shaft and an output shaft located parallel to one another, the gears disposed concentric with the input shaft are supported by ball-and-roller bearings supported by at least one stationary member which is an entity separate from the input shaft. By this arrangement, relative movements occur between inner and outer races of the ball-and-roller bearings when a rotational force is transmitted from the input shaft to the output shaft, thereby preventing or reducing the development of fretting corrosion in the ball-and-roller bearings.
