Filed:

Jul 25, 2006

Appl. No.:

11/459816

Inventors:

Jeffrey D. Jennings - Hendersonville NC, US

International Classification:

G05D 16/02

US Classification:

137510, 137494

Abstract:

A pressure regulating valve comprising a diaphragm for control of process pressure is provided. The diaphragm has a reference pressure on a first side and a process pressure on a second side. The second side is engagable with a process void and at least one vent void such that when the process pressure is below the reference pressure the diaphragm is engaged with the vent void. When the process pressure is above the reference pressure the diaphragm is not engaged with the vent void.

International Classification:

F16K 7/04

US Classification:

251 5, 251 4, 13759901

Abstract:

A pressure regulating valve includes a body having an outer surface, the interior of the body defining an inlet chamber adapted to receive a fluid at a process pressure, and an outlet chamber. The body includes at least one inlet passage communicating with the inlet chamber and the outer surface, and at least one outlet passage communicating with the outer surface and the outlet chamber. A reference housing is adapted to be disposed in fluid communication with a fluid at a predetermined reference pressure. An annular membrane is disposed between the body and the reference housing, so as to circumscribe the inlet and outlet passages. The membrane is arranged such that, when the reference pressure is higher than the process pressure the membrane engages at least one outlet passage, and when the process pressure is higher than the reference pressure, the membrane is not engaged with the outlet passage.

International Classification:

F16K 15/00

US Classification:

137529, 13751215

Abstract:

A valve includes: a body including: a wall defining a process surface, a process void in the process surface adapted to communicate with fluid at process pressure, and at least two vent voids in the wall separate from the process void; an inlet port in fluid communication with the process void; and an outlet port in fluid communication with the vent void; a reference housing adapted to communicate with fluid at reference pressure; and a membrane constrained between the body and the reference housing with its process side substantially coplanar with the process surface. The process surface incorporates at least one groove therein which defines a flow path between the near vicinity of the process void and the near vicinity of the vent voids.

Abstract:

An image transfer belt is provided for use in digital printing applications which includes a base film layer having perforations therein which are filled with a conductive polymer layer to provide controlled conductivity to the belt. The belt further includes a compliant layer over the conductive polymer layer. The resulting belt exhibits electrical properties suitable for digital image transfer. These properties may be varied according to the desired application.

Inventors:

Jeffrey Jennings - Hendersonville NC, US

International Classification:

G05D011/00

US Classification:

137/115130

Abstract:

A relief valve comprising a diaphragm for control of process pressure is provided. The diaphragm has a fluid pressure on a first side and a process pressure on a second side. The second side is engagable with a process void and at least one vent void such that when the process pressure is below the fluid pressure the diaphragm is engaged with the vent void. When the process pressure is above the fluid pressure the diaphragm is not engaged with the vent void.

International Classification:

F16K 31/12
F16K 27/00

US Classification:

251061100, 137001000, 251366000

Abstract:

A fluid system, a control valve therefor, and a method of its operation are provided. The fluid system includes a piping run, and a control valve which includes: a housing having an inlet connected to the piping run, an outlet connected to the piping run, and a pressure port; and a elastomeric tube disposed inside the housing, the tube having a flow passage extending therethrough which is in fluid communication with the inlet and outlet. An outer surface of the tube and the housing cooperatively define a pressure chamber which is in fluid communication solely with the pressure port, A source of controlled fluid pressure is connected to the pressure port to modulate flow in the tube. The tube is sized and the valve is operated so as to provide accurate flow rate control.
