  • Patent number: 10502213
    Abstract: A compressed air system may comprise an air compressor configured to generate compressed air, a reservoir configured to store the compressed air, a reservoir pressure sensor configured to monitor an actual reservoir pressure of the compressed air stored in the reservoir, an outlet valve configured to regulate a flow of the compressed air out of the reservoir, and an outlet electronic actuator configured to adjust a position of the outlet valve. The compressed air system may further comprise an electronic control module (ECM) configured to transmit a command to the outlet electronic actuator to cause the outlet electronic actuator to open the outlet valve when the actual reservoir pressure is above a target reservoir pressure, and transmit a command to the electronic actuator to cause the electronic actuator to close the outlet valve when the actual reservoir pressure is below the target reservoir pressure.

  • Publication number: 20180142602
    Abstract: A dust ejector and exhaust tube assembly is provided. The dust ejector and exhaust tube assembly comprises an exhaust tube, and a dust ejector tube at least partially located within the exhaust tube. The dust ejector tube includes a tube portion having a constant diameter smaller than a diameter of the exhaust tube. The dust ejector tube further includes an outlet portion including an outlet of the dust ejector tube. The outlet of the dust ejector tube has a diameter larger than the constant diameter of the tube portion.

  • Publication number: 20180100362
    Abstract: A compressed air system for a machine is disclosed. The compressed air system may comprise an air compressor having an inlet, an inlet valve configured to regulate a flow of air to the inlet of the air compressor, a reservoir configured to store compressed air generated by the air compressor, and a reservoir pressure sensor configured to monitor an actual reservoir pressure of the compressed air stored in the reservoir. The system may further comprise an electronic control system configured to regulate a position of the inlet valve. The electronic control system may include an electronic control module (ECM) in electronic communication with the reservoir pressure sensor and an electronic actuator operatively associated with the inlet valve to adjust the position of the inlet valve.
