Title (EN) POTENTIOMETER AND SWITCH CONTROL ARRANGEMENT
(FR) DISPOSITIF DE COMMANDE DE POTENTIOMETRE ET DE COMMUTATEUR
Abstract: front page image
(EN)A number of systems exist wherein a plurality of hydraulic motors (28a, 28b, 28c) receive pressurized fluid from a single pump (14) which is itself driven by an electric motor (12). Apparatus has been available for adjusting the power supplied to the electric motor (12), and thereby adjusting the pump (14) flow rate, in response to the operator activating one or more of the hydraulic motors (28a, 28b, 28c). However, such apparatus has generally been bulky, complicated and/or difficult to install and/or service. An improvement is provided wherein a single switch (22) is placed in either an open or closed position as an elongated member (34) placed transversely to a plurality of generally parallel rod members (20a, 20b, 20c) is rotated in response to longitudinal travel in either direction from a neutral position (32) of one of the rod member (20a, 20b, 20c). Longitudinal movement of each of the rod members (20a, 20b, 20c), controls, via a respective valve (16a, 16b, 16c), the action of the respective hydraulic motor (28a, 28b, 28c).
(FR)Dans des systemes existants, une pluralite de moteurs hydrauliques (28a, 28b, 28c) recoivent du fluide sous pression d"une seule pompe (14) qui est elle-meme entrainee par un moteur electrique (12). Un appareil a permis d"ajuster le courant qui alimente le moteur electrique (12), et par consequent de regler le debit de la pompe (14), en reponse a l"actionnement d"un ou plusieurs moteurs hydrauliques (28a, 28b, 28c) par l"operateur. Cependant un tel appareil a generalement ete encombrant, complique et/ou difficile a installer et/ou entretenir. Une amelioration consiste a monter un simple commutateur (22) soit dans une position ouverte soit dans une position fermee lorsqu"un organe allonge (34) place transversalement par rapport a une pluralite de bielles paralleles (20a, 20b, 20c) tourne en reponse au deplacement longitudinal dans l"une ou l"autre des deux directions depuis une position neutre (32) de l"une des bielles (20a, 20b, 20c). Le mouvement longitudinal de chacune des bielles (20a, 20b, 20c) commande, via une soupape respective (16a, 16b, 16c) l"action du moteur hydraulique respectif (28a, 28b, 28c).
