摘要

Booster the form of a servovalve controlling a hydraulic motor has a barrel, which is constituted by a housing 101 at the level of the plate, inclined by a cover plate 102 serving as bearing for the motor shaft 104 and the size of the lights of distribution by a plate 103 of closure for the second bearing for the said shaft, characterizes by the fact that said closure plate 103, of substantially parallelepipedal shape, comprises two longitudinal openings 130, 131 disposed parallel in a map parallel to the plane of the plate, each of these bores to communicate between them a first bore 128, 129 perpendicular to the plate and lead to in the orifice of the use of the servo valve 122 fixed on the one of the faces of the plate and a second bore 132, 133 perpendicular to the plate lead to in one of said lights of distribution, the plate comprising, in addition, at least one transverse piercing 137, 138 bringing together the two longitudinal bores and containing the safety valves 139, 140 has a double direction or their equivalent.
