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： 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 (1) rotates inside a bore (2a) of a casing and meshes with teeth (6) of a pinion or gate-rotor (7) comprised of a sealing portion (8) supported by a support portion (9). The sealing portion (8) has a limited angular play with respect to the support portion (9). This allows the sealing portion to undergo brief but abrupt accelerations or decelerations independently of the support portion (9). In order to allow frictionless angular displacement between the two portions liquid is injected between them at a moderate pressure when each tooth is out of engagement with the screw.

摘要： Liquid from the condenser 34 l is supplied to the innerspace of the motor through pipe 11 and flashes therein while cooling the motor. The resulting gas is sent through pipe 10 to an economizer hole 9 of the compressor. At full load, hole 9 is at a higher pressure than the intake of the compressor. At part load, hole 9 is at a pressure close to the intake pressure. A piston 12 is subjected on one face to the economizer hole pressure and on the other face to the intake pressure. When both pressures tend to be equal, piston 12 travels to shoulder 16 and establishes therewith a pressure drop elevating the pressure in motor housing 7, thereby to maintain in motor housing 7 a pressure able to urge liquid from the motor casing to the evaporator 37 through pipe 38.

Each of the pinion teeth is provided with two substantially rectilinear flanks, the flank located on the side of the pinion nearest the low pressure port when one tooth is engaged in the worm being longer than the flank of the same tooth which is located nearest the high pressure port.
