Multi-way flooding valve for technical fluids with linear flooding volume control, consisting of a stationary hollow shaft and a control piston which is arranged so as to be linearly displaceable therein, wherein two mutually spaced control piston bearings which have guide rings and sealing rings and are used to mount and guide the control piston are arranged on the stationary hollow shaft, and the control piston thus mounted is arranged in a manner connected to a linear drive, characterized • in that the hollow shaft is arranged in a wax depository container in the region between the bearings of the hollow shaft, • in that the wax depository container is designed as a pressurized annular wax supply line which is used to supply the control piston and keeps it under constant pressure, • in that at least one through-bore is arranged in the hollow shaft as a wax supply bore and said bore is thereby provided with at least one access (6.1 and/or 6.2) to the wax depository container, • in that each through-bore used to supply wax to the control piston has a rectangular cross-section, • in that the hollow shaft is provided with a residual wax outlet in the region outside the wax depository container, in the region of an arrangement of wax flooding outlet ports (9.1/9.2), • in that on the hollow shaft, behind and in front of the residual wax outlet, two wax flooding outlet bores are arranged opposite one another in an offset manner and are with the wax flooding connector ports (9.1 and 9.2) which are connected thereto and arranged on the outer wall of the hollow shaft, • in that the control piston which is linearly movably mounted in the fixedly arranged hollow shaft has two mutually spaced through-bores as a wax supply bore having the same cross-section in shape and dimension and in size and shape as each through-bore of the hollow shaft, • in that the distance between the two wax supply bores of the control piston corresponds to the possible linear travel of the control piston, • in that a further bore (11.1) is arranged as a wax outlet bore on one side in the wall of the control piston, and is arranged there precisely in the region of the wax flooding outlet bore of the hollow shaft for the wax flooding connector port (9.1), and a second bore (11.2) is arranged as a wax outlet bore for the wax flooding connector port (9.2) in the wall of the control piston so as to be opposite but offset relative to the bore (9.1) by the dimension of the possible linear travel of the control piston, and • the two bores (9.1 and 9.2) correspond to the two wax flooding outlet bores of the hollow shaft in shape and dimension. • in that the hollow shaft is arranged in a wax depository container in the region between the bearings of the hollow shaft, • in that the wax depository container is designed as a pressurized annular wax supply line which is used to supply the control piston and keeps it under constant pressure, • in that at least one through-bore is arranged in the hollow shaft as a wax supply bore and said bore is thereby provided with at least one access (6.1 and/or 6.2) to the wax depository container, • in that each through-bore used to supply wax to the control piston has a rectangular cross-section, • in that the hollow shaft is provided with a residual wax outlet in the region outside the wax depository container, in the region of an arrangement of wax flooding outlet ports (9.1/9.2), • in that on the hollow shaft, behind and in front of the residual wax outlet, two wax flooding outlet bores are arranged opposite one another in an offset manner and are with the wax flooding connector ports (9.1 and 9.2) which are connected thereto and arranged on the outer wall of the hollow shaft, • in that the control piston which is linearly movably mounted in the fixedly arranged hollow shaft has two mutually spaced through-bores as a wax supply bore having the same cross-section in shape and dimension and in size and shape as each through-bore of the hollow shaft, • in that the distance between the two wax supply bores of the control piston corresponds to the possible linear travel of the control piston, • in that a further bore (11.1) is arranged as a wax outlet bore on one side in the wall of the control piston, and is arranged there precisely in the region of the wax flooding outlet bore of the hollow shaft for the wax flooding connector port (9.1), and a second bore (11.2) is arranged as a wax outlet bore for the wax flooding connector port (9.2) in the wall of the control piston so as to be opposite but offset relative to the bore (9.1) by the dimension of the possible linear travel of the control piston, and • the two bores (9.1 and 9.2) correspond to the two wax flooding outlet bores of the hollow shaft in shape and dimension.
