20080236681 | Flap Valve - A valve has a first duct and a second duct into which the first duct opens at right angles, thereby defining an intersection that forms a seat for a valve disk that slides in the second duct at right angles to the seat between a closed position and an open position. The valve disk has, facing the seat, a deviation surface of curvilinear profile having a narrow base facing toward the seat and widening away from the seat configured to deflect at right angles to the first duct a gaseous stream originating therefrom. | 10-02-2008 |
20080237523 | Valve with Outlet Duct - A valve has a first duct and a second duct at right angles to the first duct. The first duct opens into a connecting portion of the second duct, defining an intersection that forms a seat for a valve disk that slides in the connecting portion in a direction at right angles to the seat between a closed position and an open position. The connecting portion has two flat walls facing one another and connected by an end wall. The first duct opens onto one of the flat walls. The end wall partially surrounds the valve disk parallel to the a direction of sliding at a distance from an edge of the valve disk that is such that, for the open position, the end wall defines with the edge of the valve disk and the seat a passage. | 10-02-2008 |
20080237526 | Flap Valve - A valve has a first duct, a second duct into which the first duct opens, thereby defining an intersection that forms a seat at right angles to the first duct for a valve disk that slides in the second duct at right angles to the seat between a closed position and an open position, and an actuator for operating the valve disk between its two positions. For the open position, the actuator is controlled to bring the valve disk into close proximity to a wall of the second duct facing the seat. | 10-02-2008 |
20080296525 | Valve with Operating Means Between Two Outlet Passages - A valve has a body, a fluid inlet duct delimited by the body, two fluid outlet ducts into which the fluid inlet duct opens, an intersection formed by the two fluid outlet ducts, a butterfly valve disposed in the intersection, and a motor, to which the butterfly valve is connected, for actuating the butterfly valve between a first extreme position in which the butterfly valve directs the fluid mainly toward the first outlet duct and a second extreme position in which the butterfly valve directs the fluid mainly toward the second outlet duct. The motor is placed between the outlet ducts in the vicinity of a connecting zone connecting the two outlet ducts to one another. The butterfly valve is mounted in front of the connecting zone so that the butterfly valve forms a screen against the fluid for the connecting zone. | 12-04-2008 |
20080308079 | Exhaust Gas Recycling Device Comprising a Flow Regulating and Selectively Connecting Valve - The invention concerns an exhaust gas recycling device comprising a cooled path ( | 12-18-2008 |
20090050830 | DUAL BUTTERFLY VALVE DRIVEN BY A COMMON DRIVE MOTOR - A valve including a body delimiting an inlet duct opening into a first and second outlet duct. The body includes a first butterfly valve element and a second butterfly valve element. The first butterfly valve element is mounted on a first transmission gearwheel connected to a drive motor and is movable into two closed positions on either side of an open position of the first duct. The first transmission gearwheel is connected to a second transmission gearwheel, on which the second butterfly valve element is connected by a one-way positive drive element. When the first butterfly valve element is moved from an open position to one of the two closed positions in the first duct, the second butterfly valve element is driven from a closed position to an open position of the second duct. The valve includes a member for returning the second butterfly valve element to the closed position. | 02-26-2009 |
20090260587 | AIR INTAKE DEVICE FOR A HEAT ENGINE WITH A COOLED MAIN CIRCULATION SYSTEM AND A BYPASS SYSTEM EQUIPPED WITH A HEATING MECHANISM - Device for air intake of a heat engine including: —a main circulation system ( | 10-22-2009 |
20090293973 | TWO-SHUTTER VALVE - A valve including a body that defines first and second ducts that open out into a third duct. The first duct is provided with a first shutter and the second duct is provided with a second shutter connected to drive means arranged to move the shutters in a normal mode of operation in which the second shutter is in the closed position and the first shutter is adjustable in position between an open position and a first closed position, a stop mode in which the second shutter is in its closed position and the first shutter is in its first closed position, and a secondary mode of operation in which the second shutter is in its open position and the first shutter is in a second closed position. | 12-03-2009 |
20090320808 | VALVE WITH BYPASS DUCT INCORPORATING A HEATING MEMBER AND COMBUSTION ENGINE INTAKE CIRCUIT WITH PREHEATING OF THE AIR - A valve for a combustion engine air intake circuit, where the valve includes a main pipe and a bypass duct with upstream and downstream ends opening into the main pipe. The valve also includes a heating member that is positioned in the bypass duct and a shut-off member mounted such that it can move between a first position in which airflow can pass through the main pipe and a second position in which airflow can pass through the bypass duct. | 12-31-2009 |

20110193005 | VALVE WITH OPERATING MEANS BETWEEN TWO OUTLET PASSAGES - A valve has a body, a fluid inlet duct and two fluid outlet ducts delimited by the body, an intersection formed at an area where the fluid inlet duct opens into the two fluid outlet ducts, and a butterfly valve disposed in the intersection. The butterfly valve is operable to be actuated between a first extreme position in which the butterfly valve directs the fluid mainly toward the first outlet duct and a second extreme position in which the butterfly valve directs the fluid mainly toward the second outlet duct. In the first extreme position, the butterfly valve has a first portion partially blocking the second outlet duct and, in the second extreme position, the butterfly valve has another portion blocking the first outlet duct. | 08-11-2011 |
