Rotary valve system

A pressurized gas system for a cupper, said cupper having at least one ram and at least one die structured to form a metal blank into a cup, wherein, after forming, the cup is disposed over the distal end of said at least one ram, said at least one ram having an ejection conduit extending therethrough, said ram election conduit having an inlet, said pressurized gas system comprising:

• a surge tank structured to contain a pressurized gas, said surge tank having an outlet;
• a motor having at least one drive shaft;
• a rotary valve assembly having a housing assembly and a rotary valve body assembly, said housing assembly having at least one inlet passage, at least one outlet passage said rotary valve assembly at least one inlet passage coupled to, and in fluid communication with, said surge tank having an outlet, said rotary valve body assembly disposed within said housing assembly and coupled to said motor, wherein said rotary valve body assembly is structured to selectively provide fluid communication therethrough;
• at least one downstream pressure conduit, each downstream pressure conduit having an inlet and an outlet, said at least one downstream pressure conduit inlet coupled to, and in fluid communication with, said rotary valve assembly at least one outlet passage, said at least one downstream pressure conduit outlet coupled to, and in fluid communication with, at least one ram ejection conduit;
• said rotary valve body assembly includes a first planar body and a second planar body;
• each of said rotary valve body assembly first and second planar bodies having at least one axial opening therethrough, each said rotary valve body assembly first and second planar body at least one axial opening being disposed at a radius so as to at least partially overlap when said rotary valve body assembly first and second planar bodies are disposed on a common axis;
• said rotary valve body assembly first and second planar bodies being rotatable disposed on a common axis;
• and
• wherein said rotary valve body assembly first planar body at least one axial opening may move relative to said rotary valve body assembly second planar body at least one axial opening between a first position, wherein said rotary valve body assembly first and second planar body at least one axial openings are substantially aligned, and a second position wherein said rotary valve body assembly first and second planar body at least one axial openings are partially aligned.
