Title (EN) TIGHT JACK FOR AUTOMATIC STEERING OF A BOAT
(FR) VERIN ETANCHE POUR PILOTE AUTOMATIQUE DE BATEAU
Abstract: front page image
(EN)Casing for electric jack presenting a maximum tightness, more particularly intended for automatic steering in boats. This casing (1), formed by a hollow metal section extending longitudinally, incorporates a means (2) deformable under the action of pressure variation inside the housing in which the jack rod (4) moves so as to balance the pressure inside said housing with that of the environment air in order to prevent water from coming inside by a pumping effect. The electrical switchings are provided by means of flexible strip switches controlled by magnet through a non-magnetic wall of the casing. There are also provided original means for fixing and guiding elements effecting relative motions.
(FR)Boitier pour verin electrique presentant le maximum d"etancheite, plus particulierement prevu pour pilotes automatiques de bateau. Ce boitier (1), forme de preference d"un profile creux developpe longitudinalement, inclut un moyen deformable (2) sous l"effet des variations de pression a l"interieur de l"enceinte dans laquelle se meut la tige du verin (4), de maniere a equilibrer la pression a l"interieur de ladite enceinte avec celle de l"air ambiant afin d"interdire toute entree d"eau par effet de pompage. Les commutations electriques se font au moyen d"interrupteurs a lames souples commandees par des aimants a travers une paroi amagnetique du boitier. L"invention est completee par des moyens originaux de fixation et de guidage des elements devant effectuer des mouvements relatifs.
