  • Patent number: 10539250
    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.

  • Patent number: 10354788
    Abstract: A universal solenoid actuator includes a housing, a flange, a single armature, a first rod, a second rod, a first coil, and a second coil. The housing defines a cavity that is devoid of permanent magnets. The flange comprises a magnetic material and divides the cavity into a first cavity portion and a second cavity portion. The single armature extends through, and is movable within, the armature opening. The first rod and second rods are coupled to opposite ends of the single armature and are moveable therewith. The first and second coils are wound such that: when the first coil is electrically energized, a first force is generated that causes the single armature to move in a first direction, and when the second coil is electrically energized, a second force is generated that causes the single armature to move in a second direction.

  • Publication number: 20180045375
    Abstract: A smart solenoid control system for controlling flow of fluid in a conduit includes a solenoid, a plurality of fluid sensors, a plurality of solenoid sensors, a display device, a communication module, and a control. Each fluid sensor senses a parameter associated with the fluid in the conduit. Each solenoid sensor senses a parameter associated with the solenoid. The display device is configured to render images. The communication module is configured to transmit received data to a remote station or handheld device. The control is coupled to receive signals from the fluid sensor signals and the solenoid sensors and determines whether the solenoid should be in a first or second position, supplies drive current to the solenoid to cause the solenoid to move to the desired position, selectively commands the display device to render images, and supplies the data to the communication module for transmission.

  • Publication number: 20160161120
    Abstract: An ignition exciter system includes an igniter, a step-up transformer, a switch device, and a spark-sustain capacitor. The igniter has a spark gap across which a spark may be generated. The step-up transformer has a primary winding that is adapted to selectively receive direct current (DC) from a DC source, and a secondary winding that is coupled to the igniter. The switch device is coupled to the primary winding and is configured to selectively operate in an ON state, in which DC may flow through the primary winding, and an OFF state, in which DC may not flow through the primary winding. The spark-sustain capacitor is coupled to the igniter and is configured to charge from a DC source when the switch device is operating in the ON state, and at least selectively discharge across the spark gap when the switch device is operating in the OFF state.
