20110103993	GEAR WHEEL WITH PROFILE CAPABLE OF MESHING WITH SEMI-ENCAPSULATION IN A GEARED HYDRAULIC APPARATUS - A geared hydraulic apparatus comprises a pair of gear wheels which mesh with each other with semi-encapsulation. Each gear wheel has a plurality of teeth with a profile which falls within a band of tolerance of ±15, more preferably ±20, and even more preferably ±30 with respect to the height of the tooth, with respect to a profile similar to a profile defined by a predetermined spline function passing through a plurality of nodal points having pre-established coordinates {X,Y} with origin on the rotational axis.	05-05-2011
20100104463	GEARED HYDRAULIC APPARATUS - 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.	04-29-2010
