Abstract

The disclosed and claimed compressed gas system provides for the use of a rotary valve assembly in association with a cupper. A compressed gas system that utilizes a rotary valve assembly uses less gas than a constant flow compressed gas system and is quieter than a compressed gas system that uses valves. The rotary valve is a disk-like body having an opening therethrough. The rotary valve body is disposed within a housing assembly wherein gas may only flow through the housing when the rotary valve body is properly aligned with a space on one side of the rotary valve body.

First claim

What is claimed is:

1. 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 ejection 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;
a controlled valve and a control unit;
said controlled valve coupled to, and in fluid communication with, said surge tank outlet and said rotary valve assembly at least one inlet passage, said controlled valve structured to be selectively configured electronically;
said control unit structured to provide an electronic valve configuration command, said control unit coupled to, and in electronic communication with, said controlled valve; and
whereby said control unit is structured to configure said controlled valve.

2. The pressurized gas system of claim 1 wherein:
said control unit structured to provide an electronic motor command;
said rotary valve assembly motor structured to adjust its speed in response to an electronic motor command;
said control unit coupled to, and in electronic communication with, rotary valve assembly motor; and
whereby said control unit is structured to control the speed of said rotary valve assembly motor.

3. The pressurized gas system of claim 2 wherein said motor includes two drive shafts, each drive shaft coupled to a rotary valve assembly.

4. 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.

5. The pressurized gas system of claim 4 wherein said rotary valve body assembly first and second planar body at least one axial openings are arcuate openings.

6. The pressurized gas system of claim 4 wherein there is one each of said rotary valve body assembly first and second planar body at least one axial openings.

7. The pressurized gas system of claim 4 wherein said multiple rotary valve body assembly axial openings are radially staggered about said rotary valve body.

8. The pressurized gas system of claim 4 wherein said at least one ram and at least one die includes multiple rams and multiple dies acting in cooperation, and wherein:
said housing assembly at least one outlet passage includes multiple housing assembly outlet passages, each housing assembly outlet passage coupled to and in fluid communication with one of said multiple rams;
wherein there is multiple each of said rotary valve body assembly at least one axial openings;
each of said multiple rotary valve body assembly axial openings structured to provide selective fluid communication between said upstream enclosed space and one of said multiple housing assembly outlet passages.

9. The pressurized gas system of claim 4 wherein said cupper includes a plurality downstream pressure conduits and wherein:
said housing assembly at least one outlet passage includes a plurality of housing assembly outlet passages, the number of housing assembly outlet passages corresponding to the number of said downstream pressure conduits, wherein each said each housing assembly outlet passage is coupled to, and in fluid communication with, one of said downstream pressure conduits;
wherein said rotary valve body assembly at least one axial openings includes a plurality of axial openings, the number of axial openings corresponding to the number of said downstream pressure conduits;
each said rotary valve body assembly axial opening structured to provide selective fluid communication between said upstream enclosed space and one of said housing assembly outlet passages.

10. 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 ejection conduit having an inlet, said pressurized gas system comprising:
