Filed:

Dec 12, 2005

Appl. No.:

11/301018

Inventors:

Walter A. Zub - Lone Tree CO, US

Assignee:

Norgren, Inc. - Littleton CO

International Classification:

F15B 13/08

US Classification:

137884, 13762564

Abstract:

A valve island that has vented non-active areas is disclosed. The valve island has a plurality of active gas passageways that are coupled together between components. At the junction between the different components the active fluid passageways are surrounded by a sealing surface. The sealing surface essentially surrounds some non-active areas. The non-active areas are vented to the outside air through one or more passageways. The non-active areas may be recessed from the sealing surface.

International Classification:

H05K 5/00

US Classification:

361752, 361730

Abstract:

A double solenoid PC board that has a long narrow section extending from the main section is disclosed. The long narrow section has a connector at the tip. The connector at the tip of the long narrow section is configured to mate with or couple to a mating connector on a single solenoid PC board in a double solenoid valve.

US Classification:

307 29, 307 39, 307 82, 307 85, 307 86

Abstract:

An electrical circuit and method for switching an input voltage onto a load by way of an AC control voltage is provided. A voltage magnitude reduction circuit is configured to be driven by the AC control voltage. A rectifier circuit is operably coupled with the voltage magnitude reduction circuit. Also, a voltage limiter circuit is operably coupled with the rectifier circuit, and an energy storage circuit is operably coupled with the voltage limiter circuit. The voltage magnitude reduction circuit, the rectifier circuit, the energy storage circuit and the voltage limiter circuit cooperatively generate a switch control voltage. An electronic switching unit is then configured to switch the input voltage across the load when the switch control voltage is active. In one embodiment, the input voltage is a DC voltage generated by an AC-to-DC voltage converter circuit configured to convert an AC supply voltage to the DC voltage.

Inventors:

Walter A Zub - Lone Tree CO, US

Assignee:

Norgren, Inc. - Littleton CO

International Classification:

F16K 11/07

US Classification:

13762566, 13762569

Abstract:

A fluid control device is disclosed that is configured to vent pilot volume through an exhaust port or exhaust passageway () integrated into the fluid control device. The fluid control device has a fluidic switch () configured to switch a pilot volume into the exhaust port or exhaust passageway () when a signal port or signal passageway () is de-pressurized. The fluidic switch () couples the signal port or signal passageway () to the pilot volume when the signal port or signal passageway () is pressurized.

Inventors:

Walter Zub - Lone Tree CO, US

International Classification:

F15B 13/00

US Classification:

137884000

Abstract:

A valve that has the solenoids aligned at an angle of 90 degrees with respect to the valve operator is disclosed. By aligning the solenoid at 90 degrees the fluid passageways in the valve operator are simplified and the operator body is easier to mold.

Inventors:

Walter Zub - Lone Tree CO, US

International Classification:

H05K 5/00

US Classification:

361679000

Abstract:

An operator for a valve that has a guiding ramp for alignment of a connector on a double solenoid PC board is disclosed. The connector from the double solenoid PC board mates with or couples to a connector on a single solenoid PC board mounted inside the operator. The guiding ramp aligns the connector from the double solenoid PC board as it is being inserted into the single solenoid operator.

Assignee:

Norgren, Inc. - Littleton CO

International Classification:

F16K 11/07

US Classification:

137884, 13762564

Abstract:

A valve island that has a pilot fluid passageway located on the side of the sub-base is disclosed. The pilot fluid passageway is formed into one side of the sub-base and couples the front end of the sub-base with the back end of the sub-base. A gasket or sealing device may be used to help form a seal around the pilot fluid passageway when the sub-base is joined to a mating part.
