Title (EN) WASTEGATE VALVE AND ASSOCIATED METHOD
(FR) SOUPAPE DE DECHARGE ET METHODE ASSOCIEE
Abstract:
(EN) A wastegate valve and associated method for controlling a flow of gas, such as a flow of exhaust gas from an exhaust inlet of a turbocharger, are provided. The wastegate valve includes multiple bypass ports that are selectively opened and closed by poppets, which are controlled by a linkage. The poppets are configured so that the pressure of the gas in the exhaust inlet biases one of the poppets to the open position and one of the poppets to the closed position. Thus, the forces resulting from the pressure of the gas on the poppets are offset, thereby reducing the force required for adjusting or maintaining the position of the linkage and the poppets.
(FR) Soupape de décharge et méthode associée pour le contrôle d’un flux gazeux, par exemple un flux de gaz d’échappement provenant de l’orifice d’échappement d’un turbocompresseur. La soupape de décharge comporte plusieurs orifices de dérivation ouverts et fermés de manière sélective par des distributeurs à clapet, contrôlés par une tringlerie. Les distributeurs à clapet sont configurés de manière à ce que la pression du gaz dans l’orifice d’échappement place l’un des distributeurs à clapet en position ouverte et un autre en position fermée. Ainsi, les forces générées par la pression du gaz sur les distributeurs à clapet sont compensées, réduisant ainsi la force nécessaire pour l’ajustement ou le maintien de la position de la tringlerie et des distributeurs à clapet.
