Abstract: An improved geared hydraulic apparatus, comprising a pair of meshing gearwheels, mounted to be reciprocally rotatable in a casing between an inlet side and an outlet side for a fluid having, in use, a substantially transverse flow with respect to the axes of rotation of the gearwheels. The meshing gearwheels create, during their reciprocal rotation, progressive meshing configurations between respective co- operating teeth. In at least one of said progressive meshing configurations is defined, in at least one cross- section of the gearwheels, at least one closed area between respective fluid entrapment teeth. The closed area decreases until it is substantially cancelled out at and around at least one other, separate progressive meshing configuration between the aforesaid respective co-operating teeth.

Abstract: A rotary screw machine, such as a screw compressor, a vacuum pump or a motor, comprises mating rotors having asymmetrical profiles and the same outer diameter. Preferably, the end of the male rotor tooth has, from the point of maximum radius, on both flanks, two portions of arcs of a circle appreciably different in size as regards radius, but tangent, which describe a part of the left-hand flank and a part of the right- hand flank respectively. The female rotor has the respective matings in the corresponding area of the bottom of the tooth. Preferably the male rotor has three or four threads, while the female rotor preferably has six or seven threads, and even more preferably the male rotor has four threads and the female rotor has seven threads. From the centre of the female rotor lines can be drawn tangent to the two flanks of the same tooth.

Abstract: An adaptor element for transmitting power between an output shaft of a motor and an input shaft of a driven machine comprises a substantially cylindrical body with a longitudinal hole on the surface of which is formed a longitudinally extending cavity for connection to the said output shaft, the said cavity in turn comprising a pair of substantially parallel lateral surfaces which can engage with corresponding bearing surfaces of a power transmission key. A distinctive feature of the invention is that the longitudinally extending cavity comprises substantially curved connecting surfaces between the said lateral surfaces , which are connected to each other to form a radial stop for the key, projecting towards the inside of the cavity. The main purpose of this is to decrease the maximum stresses on the cavity during power transmission, in order to eliminate risks of cracking and fatigue fracture of the body of the adaptor element.
