Manually-operated remote-control device, especially hydraulic manipulator, comprising: a body (1) containing at least one moving signal-generating member, controlled by a push-rod (2) projecting above the body (1) and movable by a rocking cam (4) fixed to the top of the body (1); means (5) of rotary articulation, comprising a fixed clevis mount (5a) secured to the body (1) and a moving clevis mount (5b) secured to the cam (4), these clevis mounts (5a, 5b) being coupled together so as to allow the cam (4) to rock with respect to the body (1); a base (6) secured to this cam and supporting an operating handgrip (7); characterized in that the moving clevis mount (5b) of the articulation means, the cam (4) and the base (6) are constructed in the form of a single monobloc component (14).

Manually-operated remote-control device, especially hydraulic manipulator

A hydraulic remote control distributor valve device comprises a flat body (1) having two main assembly faces (3) to enable a multiple hydraulic remote control block to be built up, and two side faces and a bottom face (5) that are narrow and on which orifices are located for receiving link couplings for hydraulic connection with a source of hydraulic fluid under pressure and with a component to be controlled. Two outlet orifices (A, B) are situated on the bottom face of the body (5) and the width e of the bottom face (5) is less than the diameter d of the link couplings suitable for fixing on the outlet orifices. The two outlet orifices (A, B) are disposed asymmetrically relative to the median plane (M) of the body (1) that extends perpendicularly to the main faces and to the bottom face (5), said orifices being offset relative to the plane (M) by an offset 1 that is equal to or greater than 1/2.sqroot.(d.sup.2 -e.sup.2). Assembly means situated on the main faces of the body (1 ) are disposed symmetrically relative to said median plane (M).
