摘要： A hydraulically operated diverter for use subsea in directing ''''pumpdown'''' or through-flow-line (TFL) tools through wyebranched flow passageways formed in a diverter body member located on submerged wellheads. In the diverter body member a paddle is hinged to a shaft at the junction of the wye-branched flow passageways for alternately diverting tools through one and the other of such passageways. A removable and replaceable paddle operator assembly, which when in operating position sealingly engages the diverter body member, contains a hydraulic piston assembly which causes a shaft, nonrotatably connected to the paddle, to rotate the paddle against the bias of a spring from one of its diverting positions in which it is normally maintained by the spring to the other of its diverting positions. The operator assembly is removable and replaceable by means of a subsea manipulator. Means are provided for testing the seals used in sealing the operator assembly to the diverter body member. The diverter shaft is configured so as to ensure its proper connection to an operator assembly shaft with which it engages. The piston assembly is designed to prevent overstressing of the diverter shaft and paddle and to limit the side load on the operator shaft bearing.
