摘要： Refrigerant liquid containing a little oil dissolved is vaporized while cooling the motor and a portion of the vaporization products is sent into the bearings to be lubricated.The large excess of available heat permits dispensing with an oil recirculating pump and keeping in the motor casing, acting as a sump, the major part of the oil present.

摘要： In a refrigerating machine, a reservoir heated by an electric motor driving a compressor contains oil up to certain level. The reservoir is fed with refrigerating liquid complemented with oil. The liquid vaporizes while oil falls down in the liquid state. A number of lubrification conduits connect individual bearings of the compressor with the reservoir above the oil level on the one hand and with the reservoir below the oil level through a micro-orifice on the other hand, so as to send to the bearings refrigerating gas loaded with an oil mist. The bearings are in fluid communication with the intake of the compressor.

摘要： In a refrigeration system, a centrifugal economizer discharges liquid towards an evaporator through a wholly static restriction (17), the dimension of which is chosen so as to allow no gas or little gas to escape with the liquid at the conditions of maximum pressure ratio in permanent operation. When the pressure ratio is lower, the flow rate allowed by the restriction tends to decrease with respect to the flow rate delivered by the compressor. This entails an increase in the radial thickness of the liquid ring in the centrifugal device. This in turn increases the pressure upstream of the restriction, whereby compensating the initial tendency of the flow rate to decrease through the restriction.
摘要翻译：在制冷系统中，离心节能器通过完全静止的限制器（17）将液体排向蒸发器，其尺寸被选择为在最大压力比的条件下不允许气体或少量气体与液体逸出永久性操作。当压力比较低时，限制容许的流量相对于由压缩机输送的流量减少。这就需要增加离心装置中液环的径向厚度。这又增加了限制上游的压力，从而通过限制补偿流量的初始趋势。

摘要： A volumetric machine comprises a cylindrical screw meshing with a pinion-wheel, a low pressure port near one end of the screw, a high pressure port near the other end of the screw, and a control slide axially movable in the bore of a housing in which the screw is rotatable. In one condition, including a series of positions, the slide more or less broadens the high pressure port and thus controls the volumetric ratio of the machine, but covers any threads of the screw which are meshing with the pinion-wheel. In another condition, the slide closes the high pressure port except a stationary port but uncovers some of the threads meshing with the screw, such as to establish a part load with a predetermined volumetric ratio.

摘要： A screw is adapted to cooperate with a casing and at least one pinion-wheel for compressing or expanding a fluid within the space located between two screw threads, the casing and a tooth of the pinion-wheel. The casing and the crests of the threads carry two cooperating surfaces, and at least part of one of the surfaces comprises lands defining continuity of the surface but being discontinued along any circle centered on the axis of the screw. The lands separate cells which trap formative seizure particles and, thus, reduce the clearance needed between the screw and the casing.

摘要： The method of energy conversion consists in burning a fuel in an oxidizing gas in order to admit the combustion gases into an expansion machine for delivering mechanical energy, in previously compressing the oxidizing gas in a positive-displacement compressor driven by the expansion machine, in injecting into the compressor a sealing and/or lubricating auxiliary liquid which is continuously cooled and separated from the compressed gas, then re-injected into the compressor. The auxiliary liquid is cooled by vaporization of water and the steam produced is entrained in the stream of compressed oxidizing gas.

The level of oil in the compressed ammonia leaving the separator is much lower than in conventional separators with coalescing elements, because the temperature is lower and there is less oil departure in oil vapor form.

The screw is carried by a shaft supported by two sets of bearings respectively disposed on each end of the screw. The casing bore is open at both ends and the high pressure end of the casing includes a hoop having an internal bore diameter substantially smaller than the diameter of the bore. The low pressure end of the casing bore is of a diameter at least equal to the diameter of the screw for introduction of the screw into the casing bore during assembly of the screw and casing.
