Abstract:
A double-effect hydraulic actuating cylinder, particularly for hydraulic steering devices of outboard marine engines, is slidably mounted on a rod coaxial with the cylinder and sealingly protruding from a head of the actuating cylinder, carrying a separating piston that divides the cylinder into two variable volume chambers. Each chamber has an inlet/outlet for the hydraulic fluid that are respectively connected to one of the inlets/outlets of a pump, and a sealing head is disposed between the cylinder and the rod and is integral with the cylinder. The rod is adapted to be connected to a fastening bracket to non-slidably fasten the cylinder to the engine, allowing a relative rotation of the engine with respect to the transom along an axis parallel to the axis of the rod. The rod has at least one flattened surface to be grasped by a tool having a correspondingly flattened engagement surface.

Claim (Index 1):
A double-acting hydraulic actuating cylinder ( 1 ), particularly for hydraulic steering devices of outboard marine engines, said outboard engines ( 5 ) having an end adapted for fastening to a transom of a watercraft, on which an engine ( 5 ) is rotatably mounted about a substantially vertical steering axis,\n wherein the actuating cylinder ( 1 ) is slidably mounted on at least one rod ( 2 ) coaxial to said actuating cylinder ( 1 ), said rod ( 2 ) sealingly protruding from at least one head of the actuating cylinder ( 1 ) and carrying a separating piston that divides the actuating cylinder into two variable-volume chambers, each one of said two chambers having at least one inlet/outlet for a hydraulic control fluid and a sealing head ( 3 ) for a relative sliding between the actuating cylinder ( 1 ) and the rod ( 2 ), said sealing head ( 3 ) being integral with the actuating cylinder, wherein said rod ( 2 ) is adapted to be non-slidably connected to a fastening bracket ( 4 ) to fasten said actuating cylinder ( 1 ) to said engine ( 5 ), so as to allow a relative rotation of said engine ( 5 ) with respect to the transom along an axis parallel to an axis of the rod ( 2 ), and wherein the rod ( 2 ) has at least one flattened surface ( 22 ) adapted to be grasped by a tool having at least one corresponding flat engagement surface engaging said flattened surface ( 22 ).
