Filed:

Jun 11, 2009

Appl. No.:

12/482871

Inventors:

Timothy J. Farrow - Fort Collins CO, US
Gregory J. Brodsack - Loveland CO, US
Ronald L. Witt - Fort Collins CO, US

Assignee:

Woodward, Inc. - Fort Collins CO

International Classification:

F16K 31/00

US Classification:

13760102, 13762528, 25112907

Abstract:

A valve assembly includes a valve housing located between a fluid inlet region maintained at a first pressure and a fluid outlet region maintained at a second pressure. A movable metering plate is located within valve housing. A fixed metering plate interacts with the movable metering plate to meter fluid flow through the valve housing. An armature is coupled to the movable metering plate and is configured to move the movable metering plate from a closed position toward an open position. The fluid admission system further includes a balancing region to balance pressure related forces acting on the movable portions of the valve, including the metering plate. A balance passageway is in communication with the balancing region and the fluid outlet region to maintain the balancing region at the second pressure of the fluid outlet region when the movable metering plate is in the closed position.

International Classification:

H02K005/00
H02K005/24

US Classification:

310/051000, 310/089000

Abstract:

A rotary electrical actuator for mounting to a support surface in industrial applications having integral electronics that are isolated by vibration isolators from vibrations. The rotary actuator comprises a stator housing supporting a lamination stack and coils. The actuator housing has a mounting structure for mounting to the support surface (such as the mounting surface of an engine or a turbine for example) for support thereby. A rotor is carried for rotation in the stator housing. The actuator further comprises an electronics housing containing the electronics that control output of the electrical actuator. Vibration isolators supported by the stator housing in turn support the electronics housing, whereby vibrations received at mounting structure and traveling through the stator housing are dampened prior to traveling to the electronics housing. A number of embodiments are disclosed utilizing a tie rod assembly concept for the vibration isolators.

Assignee:

Woodward, Inc. - Fort Collins CO

International Classification:

A62C 4/02
F16K 17/36
G01M 3/04

Abstract:

A flame arrestor screw for a solenoid operated gas admission valve. The flame arrestor screw may include a screw body having a first end and an open end. The flame arrestor screw may include a gas passage extending from the open end along a longitudinal axis of the screw body and terminating at a terminal end within the screw body. A through hole may extend through the screw body transverse to the gas passage and in fluid communication with the gas passage.

International Classification:

H01F 7/08
H01F 7/128

Abstract:

An enhanced safety coil that prevents crack formation and propagation to the coil windings from external sources and prevents exposure to fuel is provided. The enhanced safety coil may be used in a solenoid operated gas admission valve (SOGAV), and includes a plastic encapsulation body having at least one body de-stress feature, a coil wound on the plastic encapsulation body, a sleeve forming an outermost side protective wall configured to accommodate the plastic encapsulation body and coil therewithin, and potting provided between the plastic encapsulation body and the sleeve to seal the coil therein. The body de-stress feature is configured to reduce at least one of a formation or a propagation of a crack through the potting to the coil. The plastic encapsulation body forms retention latches configured to mate with a stator.

International Classification:

F02M 63/00

US Classification:

2395332, 239 1

Abstract:

A feedthrough device includes first and second opposing outer end faces. The feedthrough device includes an opening, between the first and second opposing outer end faces, that allows fluid communication between an interior and an exterior of the feedthrough device. A conductor extends through the feedthrough device from the first end face, through the interior, to the second end face.
