Title (EN) MULTI-PATH FLUID DIVERTER VALVE
(FR) SOUPAPE DE DÉRIVATION DE FLUIDE À TRAJETS MULTIPLES
Abstract:
(EN) A multi-path fluid flow control valve for a shock absorber that restricts fluid into a first path while opening fluid flow to a second path when a given fluid flow velocity is reached. Exemplary configurations of this diverter valve are disclosed such as a spring loaded disc valve with face sealing lands, and a spool valve with diametric sealing lands. Applications include active suspension dampers in order to limit maximum RPM into a hydraulic motor. For such a system, in one mode the diverter valve allows fluid to move unrestricted into the hydraulic motor. When fluid velocity reaches a tunable set point, in a second mode the diverter valve restricts flow into the hydraulic motor and bypasses it shuttling fluid into the opposite side of the damper. In some cases progressive damping valves are utilized in series or parallel to smooth damping characteristics during, before, and after transitions.
(FR) L'invention porte sur une soupape de régulation de débit de fluide à trajets multiples pour un amortisseur, qui limite l'envoi de fluide dans un premier trajet tout en ouvrant un flux de fluide à un second trajet lorsqu'une vitesse de flux de fluide donnée est atteinte. L'invention concerne des configurations à titre d'exemple de cette soupape de dérivation, telles qu'une soupape à disque chargé par ressort qui a des plats d'étanchéité de face, et un distributeur à tiroir ayant des plats d'étanchéité diamétraux. Des applications comprennent des amortisseurs de suspension active destinés à limiter une vitesse de rotation maximale d'un moteur hydraulique. Pour un tel système, dans un premier mode, la soupape de dérivation laisse le fluide entrer sans limitation dans le moteur hydraulique. Dans un second mode, lorsque la vitesse de fluide atteint un point prédéfini qui peut être accordé, la soupape de dérivation limite un flux dans le moteur hydraulique et le contourne en envoyant le fluide dans le côté opposé de l'amortisseur. Dans certains cas, des soupapes d'amortissement progressif sont utilisées en série ou en parallèle pour adoucir des caractéristiques d'amortissement pendant, avant et après les transitions.
