| 20120111678 | MASTER CYLINDER ASSEMBLY, IN PARTICULAR FOR BALANCING A BRAKING SYSTEM OF AN AGRICULTURAL VEHICLE - The invention concerns a master cylinder assembly ( | 05-10-2012 |
| 20120107162 | VARIABLE CAPACITY FLUIDIC MACHINE - An internal gear fluidic machine, in particular a pump for the lubrication circuit of a motor vehicle engine, comprises an operating part including an external gear ( | 05-03-2012 |
| 20110256012 | POSITIVE DISPLACEMENT PUMP WITH IMPELLER AND METHOD OF MANUFACTURING - A rotary positive displacement pump ( | 10-20-2011 |
| 20100034675 | VACUUM PUMP PROVIDED WITH A DEVICE FOR ITS DEACTIVATION - A vacuum pump has inside the pumping chamber valves intended to control the operation by opening and closing during the suction and delivery cycle of the pump. The valves or parts connected thereto are formed at least in part by a ferromagnetic material. A magnetic inductor is applied outside a wall, formed by a non ferromagnetic material, of the pumping chamber of the pump, and inside the pumping chamber are installed conducting elements of ferromagnetic material, for conducting magnetic flow produced, by the inductor, up to polar points close to the positions taken in the conditions of inactivity by the valves, so as to magnetically attract the valves ( | 02-11-2010 |
| 20100028189 | ROTARY PUMP WITH VANES - A rotary pump includes a stator having a chamber delimited by a circumferential wall, a cylindrical rotor tangent to the circumferential wall of the chamber and suitable for being driven in rotation around an axis eccentric with respect to the chamber, and at least a vane diametrically traversing the rotor by delimiting in the rotor two half shells, mutually separated by the walls guiding the vane. The two half shells are hollow, and inside these hollow half shells are housed elastic leaf springs forming one-way valves with respect to four passageways formed in the half shells; the discharge of the air-oil mixture takes place, after a centrifugation and a partial recycling, through passageways, also in the case of a counter rotation of the pump. This configuration allows a bidirectional use of the same rotor. | 02-04-2010 |
| 20090104063 | ROTOR FOR A VANE PUMP, MADE OF PLASTIC MATERIAL REINFORCED BY METALLIC FOIL | 04-23-2009 |
| 20090071778 | VALVE FOR DISCONNECTING THE FRONT BRAKING AND/OR THE TRAILER BRAKING, FOR A FARM TRACTOR OR A SIMILAR VEHICLE - A valve intended to disconnect, in specific circumstances, the braking of the front wheels, and/or of a trailer whose braking system is connected through a trailer braking valve, for the braking system of a farm tractor or similar vehicle which comprises two master cylinders, operated by two separate braking pedals, directly controlling the braking of the rear wheels, and controlling the braking of the front wheels and/or the braking device of the trailer through the disconnection valve. The disconnection valve includes a body, a first and second inlet connections connected to the two master cylinders, and a delivery connection connected to a braking circuit of the front wheels and/or to the trailer brake valve. The valve body has a bore wherein is installed one movable piston subjected to the action of pressure applied to the first inlet connection. | 03-19-2009 |
| 20080230343 | Coupling - A device for controlling the activation of an apparatus by a motor, intended to be inserted between, the operation output of the motor and the operation input of the apparatus whose activation is to be controlled. The device includes: —a blade pump having a rotor, at least one blade carried by this rotor and a rotary body forming a pumping chamber missing an outlet, and one of the component parts, among the rotor and the rotary body, being connected to the operation output of the motor, whilst the other of these component parts is connected to the operation input of the apparatus to be controlled; —and a supply intended to supply liquid to the pumping chamber. | 09-25-2008 |
