Abstract

A voltage block comprises first and second reservoirs and a switching device including an inlet port, an outlet port, a first reservoir port and a second reservoir port. The switching device is mounted in a third reservoir for movement between a first position and a second position. The third reservoir includes an electrically non- conductive fluid medium in which at least a portion of the switching device is immersed.

Claims (10)

1. A voltage block comprising first and second reservoirs, a switching device including an inlet port, an outlet port, a first reservoir port and a second reservoir port, the switching device mounted for movement between a first position and a second position in a third reservoir, the third reservoir including an electrically non-conductive fluid medium in which at least a portion of the switching device is immersed.
2. The voltage block of claim 1 including a first valve, a second valve, a third valve and fourth valve, the first, second, third and fourth valves immersed in the electrically non-conductive fluid medium.
3. The voltage block of claim 1 wherein the first and second reservoirs comprise piston-and-cylinder fluid motors.
4. The voltage block of claim 3 wherein the first and second reservoirs together comprise a double-acting, piston-and-cylinder fluid motor.
5. The voltage block of claim 1 wherein the third reservoir comprises a tank including a track to which the switching device is mounted for movement between the first and second positions.
6. The voltage block of claim 5 wherein, when the switching device is in the first position, the first valve couples the inlet port to the first reservoir port and the second valve couples the second reservoir port to the outlet port, and when the switching device is in the second position, the third valve couples the inlet port to the second reservoir port and the fourth valve couples the first reservoir port to the outlet port.
7. The voltage block of claim 1 wherein the third reservoir includes means for movably mounting the switching device, the voltage block further including means for moving the switching device between the first and second positions.

9. A method of coating an article comprising providing first and second reservoirs, providing a switching device, providing on the switching device an inlet port, an outlet port, a first reservoir port and a second reservoir port, providing a
8 third reservoir including an electrically non-conductive fluid medium, mounting the switching device in the third reservoir for movement between a first position and a second position, and at least partially immersing the switching device in the electrically non-conductive fluid medium in the third reservoir.
10. The method of claim 9 wherein providing a switching device and providing a third reservoir together include providing first, second, third and fourth valves, and at least partially immersing the switching device in the electrically non-conductive fluid medium in the third reservoir includes immersing the first, second, third and fourth valves in the electrically non-conductive fluid medium.
11. The method of claim 9 wherein providing first and second reservoirs comprises providing piston-and-cylinder fluid motors.
12. The method of claim 11 wherein providing first and second reservoirs together comprises providing a double-acting, piston-and-cylinder fluid motor.
13. The method of claim 9 wherein providing the third reservoir comprises providing a tank including a track and providing the switching device includes mounting the switching device on the track for movement between the first and second positions.
14. The method of claim 13 including coupling the inlet port to the first reservoir port through the first valve and coupling the second reservoir port to the outlet port through the second valve when the switching device is in the first position, and coupling the inlet port to the second reservoir port through the third valve and coupling the first reservoir port to the outlet port through the fourth valve when the switching device is in the second position.
15. The method of claim 9 further including movably mounting the switching device and moving the switching device between the first and second positions.
16. The method of claim 9 further including providing a coating material source, a coating dispensing device, a high magnitude electrostatic potential source, coupling the source and the inlet port, coupling the first reservoir and first reservoir port, coupling the second reservoir and second reservoir port, and coupling the outlet port and the coating dispensing device.
17. The voltage block of claim 1 further comprising molecular sieves in the third reservoir.
18. The voltage block of claim 17 wherein the molecular sieves are
9 renewable.
