  • Patent number: 10451061
    Abstract: A compression system is disclosed having a compressor and a seal package including a non-contact seal and one or more radial shaft seals. In one form the non-contact seal is placed in proximity to a high pressure portion of the compressor. The offset of the non-contact seal from a shaft used to drive the compressor allows some amount of pressure reduced leakage air to pass. A radial shaft seal is coupled to the shaft axial aft of the non-contact seal on the other side of the compressor and oriented to discourage further passage of the leakage air past the radial shaft seal. A vent conveys leakage air to return to the compressor. A backup radial shaft seal can be used axially aft of the first radial shaft seal. A further radial shaft seal is disposed adjacent to the backup seal and oriented in the other direction to seal lubricant for a bearing.

  • Publication number: 20190262977
    Abstract: An impact tool of the present disclosure provides an impact mechanism having a hammer and an anvil, the hammer being rotatable about a first axis and to periodically impact the anvil to drive rotation of the anvil about the first axis. The electric motor includes a plurality of pole pairs of windings and a rotor that is rotatable with respect to consecutively energized pole pairs of windings. No encoder or sensor is electronically coupled to the electric motor to detect a position of at least one magnet attached to the rotor with respect to at least one pole pair when the rotor is in a stopped condition. When the rotor is in the stopped condition, the motor controller energizes the at least one pole pair to initiate rotation and detect a back EMF generated by movement of the rotor without a sensor or encoder to indicate the predetermined location of the at least one magnet attached to the rotor with respect to the at least one pole pair.
