Abstract: A solenoid actuator includes a housing assembly, a bobbin assembly, a coil, an armature, an actuation rod, a guide ring, a lower spring guide, an upper spring guide, and a spring. The actuation rod is fixedly coupled to the armature, and the guide ring, the lower spring guide, the upper spring guide, and the anti-rotation structure all comprise a non-metallic material.

Abstract: An air turbine start system includes an air supply duct, an air turbine starter, a starter air valve, a stepper motor, and a controller. The air turbine starter is coupled to the air supply duct to selectively receive a flow of pressurized air therefrom. The starter air valve is mounted on the air supply duct and is movable between a closed position and a plurality of open positions. The stepper motor is coupled to the starter air valve and is configured, in response to valve position commands, to move the starter air valve between the closed position and one or more of the plurality of open positions. The controller is coupled to the stepper motor and is configured to supply the valve position commands to the stepper motor and determine a position of the starter air valve based on the valve position commands supplied to the stepper motor.

Abstract: A high vibration, high-cycle, pulse width modulated (PWM) solenoid actuated valve assembly includes a valve housing and a solenoid actuator. The solenoid actuator is coupled to the valve housing and includes a solenoid housing, a bobbin assembly, a coil, an armature, a glide structure, an actuation rod, and an anti-rotation guide structure. The glide structure is disposed at least partially within the armature and between the armature and the inner surface of the yoke. The actuation rod is coupled to, and is axially movable with, the armature, it also extends into the valve housing and has a ball valve integrally formed thereon. The anti-rotation guide structure is disposed within the valve housing and surrounds at least a portion of the actuation rod. At least the actuation rod and the anti-rotation guide each have structural features formed thereon that mate with each other and prevent rotation of the actuation rod and the armature.
