Title (EN) DEVICE FOR THE TRANSMISSION OF THE LOAD PRESSURE COMPRISING AT LEAST A VALVE FOR THE CONTROL OF AN APPARATUS
(FR) DISPOSITIF DE TRANSMISSION DE LA PRESSION DE CHARGE COMPRENANT AU MOINS UNE SOUPAPE POUR LA COMMANDE D'UN APPAREIL
Abstract: front page image
(EN)Device for the transmission of the load pressure comprising at least a valve for the control of an apparatus - particularly of a manipulator from a receiver member or load arm having an upper arm pivoting on a socket or the like and hinged to a lower arm provided with a reception end for receiving the load and, as a control sensor member, a manual control arm of a smaller size than the load arm, the pivoting joints or bearings of the receiver member or load arm and of the sensor member or control arm being interconnected - is made responsive to a device of the afore mentioned type as to its manipulation or control. The valve (30) comprises a hydraulic pilot member wherein the load pressures present at the measuring points are effective on the inlet of at least one throttle valve (37). The desired control pressures are obtained by means of opening sections of the valve (37) or of a threaded valve (68). At least one regulator piston (70) is subjected on one hand to the load pressures and on the other hand to the control pressures. The hydraulic valve for controlling the load pressure comprises preferably control ribs and chokes wherein the ratios between the throttling sections are determinant for the control pressures. Members transmitting signals of effective value and arranged on the pivoting joints or bearings of the control arm are connected to members providing order signals and located on the pivoting joints or bearings of the load arm by means of an electro-hydraulic bearing adjusting device provided with at least one load pressure transmission hydraulic member.
(FR)Un dispositif de transmission de la pression de charge comprenant au moins une soupape pour la commande d'un appareil - en particulier d'un manipulateur a partir d'un organe recepteur ou bras de charge ayant un bras superieur pivotant sur un socle ou analogue et articule a un bras inferieur muni d'une extremite de reception de la charge, et, comme organe capteur de commande, un bras de controle manuel a plus petite echelle que le bras de charge, les articulations ou les coussinets de pivotement de l'organe recepteur ou bras de charge et de l'organe capteur ou bras de controle etant relies entre eux sera sensibilise par un dispositif du genre precite en ce qui concerne sa manipulation ou sa commande. La soupape (30) comprend un organe pilote hydraulique dans laquelle les pressions de charge presentes aux lieux de mesure agissent sur l'entree d'au moins un clapet d'etranglement (37). Les pressions de commande desirees sont obtenues au moyen des sections d'ouverture du clapet (37) ou d'une vanne filetee (68). Au moins un piston regulateur (70) est soumis d'un cote aux pressions de charge et de l'autre cote aux pressions de commande. La soupape hydraulique de commande de la pression de charge comprend de preference des aretes de commande et des etranglements dans lesquels le rapport entre les sections d'etranglement sont determinantes pour les pressions de commande. Des organes emettant des signaux de valeur effective et disposes sur les articulations ou les coussinets de pivotement du bras de controle sont relies a des organes emettant des signaux de consigne et situes sur les articulations ou les coussinets de pivotement du bras de charge au moyen d'un dispositif d'ajustement des coussinets electro-hydraulique pourvu d'au moins un organe hydraulique de transmission de la pression de charge.
