20130133628 | LOW ACTUATING FORCE CANISTER PURGE VALVE - A canister purge valve for an internal-combustion engine is provided with a housing including a supply channel that connects a fuel-vapor inlet port to a fuel-vapor outlet port. A valve scat is disposed across the supply channel. A valve shutter has a pressure-compensating channel and is movably mounted within the supply channel to move from an “open” position, in which the valve shutter is distant from the valve seat, to a “closed” position, in which the valve shutter is pressed against the valve seat. A rigid stem is mechanically coupled to the valve shutter to move the valve shutter from the “open” position to the “closed” position and seals the; pressure-compensating channel in the “closed” position. | 05-30-2013 |

20130173150 | SYSTEM AND METHOD FOR ESTIMATING THE MOST PROBABLE PATH OF A VEHICLE TRAVELLING ON A ROAD - A system for estimating the most probable path followed by a vehicle on a road network, including a device for acquiring a data element for locating the vehicle on the road network; a map of the territory through which the road network passes, comprising data indicative of the corresponding designated use of a plurality of areas of territory associated with the sections of the road network; and a processing unit arranged to assign an improved travel probability to a road section as a function of the designated use of the area of territory associated with the aforesaid road section. The system calculates the most probable path for the vehicle according to the improved probabilities assigned to the consecutive road sections. A method for estimating the most probable path followed by a vehicle on a road network is also disclosed. | 07-04-2013 |

20130213029 | HYDRAULIC SERVO-CONTROL OF A SERVO-CONTROLLED GEARBOX - A hydraulic servo-control of a servo-controlled gearbox comprises hydraulic actuators defining chambers, a storing tank containing control fluid used by the actuators at room pressure, a hydraulic accumulator containing control fluid under pressure, a motor pump drawing the fluid from the tank and feeding it under pressure to the accumulator, and solenoid valves selectively connecting the chambers to the tank and accumulator. The accumulator includes an outer housing defining an inner cylindrical surface defining a first diameter, a piston arranged and axially slidable and mobile inside the housing and defining there a first variable-volume chamber for a gas and second variable-volume chamber for the fluid under pressure, and a limit stopper arranged at an open end of the housing, acting as a striker for the piston, and having an annular circlip defining an opening and overall second diameter approximating by excess the first diameter of the surface of the housing. | 08-22-2013 |
