摘要： The invention relates to a refrigeration system of the air cycle cooling system type, also called reversed Brayton cycle in which the air flows through compressor means (12, 16), heat exchanger means (24) for withdrawal of heat from the compressed air and finally expander means (22) from where it is delivered to perform cooling. According to the invention the system includes heat load means (41) having a large flow resistance, creating a considerable over-pressure at the expander outlet (23). A rotary screw machine is included in the expander means (22) and also in the compressor means (12, 16), which latter screw rotor machine (12) is driven solely by the screw rotor machine (22) of said expander means. A screw rotor machine (16) connected in parallel with the screw rotor machine (12) of said compressor means is driven separately, preferably by a drive engine (19), the rotational speed of which is controlled by pressure sensing means (36) in a conduit between the expander outlet (23) and an inlet to the heat load means (41), and thereby - via said expander means - also drives the velocity of the screw rotor machine (12) of said compressor means. The sytem is particularly intended for cooling the electronic equipment in aircraft when being on the ground.

摘要： The present invention relates to a pair of co-operating screw rotors (1, 2), where each rotor (1, 2) has helically extending lobes (6, 7) and intermediate grooves, through which the rotors intermesh. One rotor is a male rotor (1) where each lobe (6) in a section perpendicular to the rotor axes (OM, OF) has a leading lobe flank (14) and a trailing lobe flank (15), both being substantially convex. The other rotor is a female rotor (2) where each lobe (7) in the same section has a leading (16) and a trailing (17) lobe flank, both being substantially concave. Each lobe of the male and female rotor has an asymmetric profile. According to the invention at least one (14, 15) of the flanks of a male rotor lobe has a circular arc segment (11, 18), which at least at each end of the segment has the shape of a circular arc. Each circular arc shaped portion of the segment has equal radius (R1; R2) and coinciding centre of curvature (A1M, A2M). This radius (R1; R2) deviates from the difference between the external radius (RM) and the pitch radius (RMP) of the male rotor. The female rotor lobe flank (17, 16) co-operating with said one flank has a flank segment (10, 19) co-operating with said flank segment (11, 18) of the male rotor lobe. The invention also relates to a screw rotor intended to be one of the rotors in such a pair and to a rotary screw machine provided with such pair of screw rotors.

摘要： In a rotary displacement compressor, preferably of the screw rotor type there is provided a first liquid circulation circuit with liquid injection means (15) and a liquid separator (16) in the outlet channel (14) of the compressor. A second liquid circulation circuit including a pump (20) is provided for lubricating the bearings (9, 10), which circuit operates at a lower pressure level than the first circuit. Therethrough the amount of compressed gas dissolved in the liquid supplied to the bearings (9, 10) is kept at a low level so that the lubrication ability of the liquid, usually oil, will be maintained. According to the invention a leakage connection (31) is present which communicates the high pressure end of the compressor working space (3) to a liquid tank (26) in the second circuit, and through a drainage connection (32) that tank (26) is in communication with the compressor working space (3) at a lower pressure. Through the drainage connection (32) the pressure in the second circuit corresponds to that lower pressure, and through the two connections (31, 32) the amount of liquid in the second circuit is controlled.

摘要： The invention relates to a method of manufacturing rotors of the kind having helical lands and intermediate grooves. A rotor body (2) is moulded or formed in some other way on a shaft (1) to only a small degree of accuracy, whereafter an outer layer (3) of polymer-based material is moulded on the rotor body to a high degree of accuracy. For the purpose of eliminating shrinkage-induced distortion of the lands of the rotor body (2) subsequent to applying the outer layer, the rotor body is produced in a multiple of layers (21, 22), by casting or like moulding processes, with each of said body layers having a thickness which is greater than that of the outer layer (3).

摘要： The invention relates to a method and to an arrangement for sensing the clearance between an object and an object-adjacent surface. The process of sensing the clearance is intended for application particularly in the case of difficult ambient conditions, such as in dirty, corrosive environments and under varying temperature and pressure conditions, e.g. to measure and hold constant the clearance between the sector plates (3, 4) of a regenerative rotary air preheater and the end surfaces of the rotor (2, 8). The invention is characterized in that the sensing device (7) used is comprised of a compressed-air operated pipe (9) which is mounted on the object (3, 4) and which includes a sound-emitting opening (14) located adjacent the surface (8), wherewith changes in the distance (S) between the object (3, 4) and the surface (8) are represented by changes that occur in the frequency of the pipe (9).
