Title (EN) CONTROL CIRCUIT FOR VARIABLE DISPLACEMENT PUMPS WITH OVERRIDE VALVE
(FR) CIRCUIT DE COMMANDE POUR POMPES A DEPLACEMENT VARIABLE AVEC VANNE PRIORITAIRE
Abstract: front page image
(EN)A fluid control circuit for selectively varying the displacement of a variable displacement pump (P), such as the type employed in a hydrostatic transmission, comprises a primary control circuit connecting a pressurized fluid source (10) with the pump (P) and adapted to be actuated to selectively vary the displacement of the pump (P) between minimum and maximum values. A separate override control circuit is connected to the primary control circuit to override it to selectively vary the displacement of the pump (P).
(FR)Un circuit de commande de fluide pour faire varier de maniere selective le deplacement d"une pompe a deplacement variable (P), du type utilise dans une transmission hydrostatique, comprend un circuit de commande primaire connectant une source de fluide sous pression (10) a une pompe (P) et concu pour etre actionne de maniere a modifier selectivement le deplacement de la pompe (P) entre des valeurs minimum et maximum. Un circuit de commande separe prioritaire est connecte au circuit de commande primaire pour dominer celui-ci de maniere a faire varier selectivement le deplacement de la pompe (P).
