Title (EN) APPARATUS FOR SUPPLYING FLUID TO A PLURALITY OF MECHANISMS
(FR) APPAREILLAGE POUR L"ALIMENTATION EN FLUIDE D"UNE PLURALITE DE MECANISMES
Abstract: front page image
(EN)Apparatus for supplying pressurized fluid to various controlled members (16, 30, 34). A problem with prior apparatus is the need for a plurality of separate apparatuses to supply the controlled members. The invention solves this problem through the use of a single valve (25) that controls the supply of pressurized fluid from a fluid source to first (34), second (16) and third (30) controlled members, in which the single valve (25) has a first relief valve segment (46) to relieve the pressure of fluid flowing from the source to the first controlled member (34), a second relief valve segment (100) to relieve the pressure of fluid relieved by the first relief valve segment (46), and a third valve segment (138) to direct the fluid relieved by the first relief valve segment (46) to the second (16) and third (30) controlled members. A movable lever (26) is connected to the third valve segment (138) to shift this valve segment (138) and control the direction of the fluid. The invention is used principally in hydraulic circuits for earthworking vehicles to actuate a plurality of controlled members including a flywheel clutch and clutch brake, and steering clutches and vehicle brakes.
(FR)Appareillage pour l"alimentation en fluide pressurise de divers organes commandes (16, 30, 34). Un probleme que presentaient les appareillages precedents residait dans la necessite de prevoir une pluralite d"appareillages separes pour l"alimentation des differents organes. L"invention resout ce probleme par l"utilisation d"une seule vanne (25) qui controle la fourniture de fluide pressurise depuis une source de fluide a un premier (34), a un second (16) et a un troisieme (30) organe commande la vanne unique (25) possedant un premier segment (46) pour diminuer la pression du fluide s"ecoulant de la source vers le premier organe (34) un second segment (100) pour detendre la pression de fluide detendu par le premier segment (46) et un troisieme segment (138) pour diriger le fluide detendu par le premier segment (46) vers le second (16) et le troisieme organes. Un levier amovible (26) est relie au troisieme segment pour le deplacer (138) et controler la direction du fluide. L"invention est utilise principalement dans des circuits hydrauliques de vehicules de terrassement pour actionner une pluralite d"organes comprenant un embrayage a volant, un frein d"embrayage, des embrayages de direction et des freins de vehicule.
