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 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： A positive displacement machine such as a hydraulic pump or motor comprises a screw with several threads rotatable inside a casing and meshing with at least one pinion, and at least one low pressure port and at least one high pressure port located in the casing on either side of the pinion. The portion of the casing comprised between a low pressure port and a high pressure port is in leaktight contact with the whole length of the top of at least one thread of the screw. When said portion is in contact with the tops of two threads, no pinion tooth is in mesh between them. The threads terminate on each side of the screw on substantially equal diameters and have in their central section a swollen portion with an external diameter larger than at the ends of the threads.

摘要： A process to control the delivery of a single screw compressor comprising a screw meshing with two pinion wheels and rotatable inside a casing. A channel with obturating means is provided to connect the high pressure orifice pertaining to a one pinion-wheel and the low pressure orifice. Auxiliary orifices are arranged to connect the various zones of the casing exposed to pressure with the low pressure orifice, said auxiliary orifices being provided with obturating devices. Said orifices are sequentially opened to diminish the delivery, starting from the orifice located near the low pressure orifice. First, the orifices pertaining to the first pinion wheel are sequentially opened. Then, the channel connecting the high pressure orifice of the first pinion and the low pressure orifice is opened. Then, the auxiliary orifices pertaining to the second pinion are sequentially opened.

摘要： A compressor or expansion machine for fluids comprises a rotor, a casing at least partially surrounding the rotor and a pinion which is rotatable about an axis which is not parallel to the rotor axis. The rotor is provided with helical threads having crests which are disposed on a surface of revolution about the rotor axis and the pinion has teeth which engage between two adjacent threads of the rotor to form a compression or expansion chamber in conjunction with the casing, the flanks of the pinion teeth comprising at least three skewed surfaces which intersect in at least two edges.

摘要： A tool having only an end cutting-edge carries out a first movement of penetration into a screw blank so as to produce a groove having flanks substantially parallel to the pinion axis. The tool-holder is angularly displaced with respect to the spindle which carries the screw blank. A second movement of tool penetration takes place while the relative displacement is progressively reduced in order to obtain an inclined flank which produces a V-shaped profile. The screw is intended to form part of a compression and expansion machine and to cooperate with at least one pinion having V-form teeth.

摘要： The crest of a projecting helical thread formed on a rotor is located on a surface of revolution with respect to the rotor axis and cooperates in a fluid-tight manner with a stationary casing which surrounds the rotor. At least one toothed sealing wheel is engaged with the rotor thread so as to rotate about a transverse axis with respect to the rotor axis and one face of each tooth which is in mesh with the thread is exposed to the high-pressure fluid. The portions of each tooth-flank which are adjacent to said face are portions of surface of revolution and include those zones of the flanks which come into contact with the thread during rotational motion.
