Abstract

L'invention porte sur un dispositif de commande de volume ayant un carter qui présente un passage d'entrée, un passage de sortie et une chambre interne communiquant avec les passages d'entrée et de sortie. Un accumulateur est positionné de façon mobile à l'intérieur de la chambre interne et se conforme sensiblement aux parois de la chambre interne, l'accumulateur comprenant un passage interne qui permet l'écoulement du fluide à travers celui-ci. Un clapet de non-retour est placé dans le passage interne de l'accumulateur, le clapet étant sollicité dans une position fermée et un siège réglable est placé à l'intérieur de la chambre interne de carter entre l'accumulateur et le passage de sortie de carter. Un mécanisme de positionnement s'accouple au carter et au siège réglable, de telle sorte que la position du siège réglable à l'intérieur de la chambre interne de carter peut être fixée de façon réglable.A volume control device having a housing having an inlet passage, an outlet passage and an inner chamber communicating with the inlet and outlet passages. An accumulator is movably positioned within the inner chamber and substantially conforms to the walls of the inner chamber, the accumulator including an internal passageway that allows fluid flow therethrough. A non-return valve is placed in the internal passage of the accumulator, the valve being biased in a closed position and an adjustable seat is placed inside the internal chamber of the housing between the accumulator and the outlet passage. of crankcase. A positioning mechanism mates with the housing and the adjustable seat, so that the position of the adjustable seat within the inner housing chamber can be adjustably fixed.
