Improvements to a hydraulic drive device for raising and lowering the lid and seat of toilettes, characterized by a left and right modules comprising a casing with a central transverse shaft whose ends protrude, said casing is divided into three recesses; the left shaft end is attached to the lid and the right shaft end to the seat, the opposite end being fixed to a drive plate of three flaps, remaining housed one flap in each recess of the casing, also housing a cylindrical diaphragm, which when filled with water pressing simultaneously the flaps causing a partial rotation of the shafts, which being coupled to the lid and seat are raised together or separately or are folded down in its rotary displacement when they are discharged; said diaphragms are fed through a check valve that allows the passage of feed water to fill the diaphragms and to discharge the diaphragms through a duct into the toilet tank when the toilet button is actuated; said left and right valves of actuation by foot are connected to a general water distributor connected to the water supply duct.
