Rotating stinger valve for j-slot connector

A petroleum well toolstring valve comprising a drill pipe string-conveyed J-slot running tool for a top stinger on a retrievable bridge plug, both having a central connector and stinger bores, said J-slot running tool having:

• a J-slot sleeve with J-slots for disconnectably receiving said stinger with lugs of said top stinger,
• said top stinger having a cylindrical stinger portion with J-slot connecting lugs,
• wherein an internal plug is arranged between said connector and stinger bores, a cylindrical neck on said stinger portion spanning said internal plug in the axial direction, with an upper radial port into said central connector bore, and a lower radial port into said stinger central bore,
• wherein said cylindrical neck, when covered by said J-slot sleeve, forms an annular flow space, fluid connecting said upper and lower radial ports and thus said central bores,
• wherein said stinger portion having has a rotatable sleeve valve body arranged on a cylindrical inner, static, stinger valve stem portion of said stinger portion and extending at least to above said lower stinger port, and
• wherein said sleeve valve body has a sleeve valve port arranged for being aligned with said lower stinger port when rotated into an open position, said rotatable sleeve valve body connected to said lugs for being rotated RH or LH by said drill pipe string for opening or closing said valve.
