Abstract: Compressed air dryer systems are described. In an aspect, a system includes, but is not limited to, a plurality of dryer modules and a controller operable to regulate a run-time of each of the plurality of dryer modules. Each dryer module is configured to direct a portion of cooling medium past a stream of compressed air. Each dryer module includes a temperature sensor in thermal communication with the portion of cooling medium, and a chiller configured to reduce a temperature of the portion of cooling medium based on the sensed temperature and a temperature set-point. The controller communicatively is coupled with the plurality of dryer modules and operable to monitor a plurality of run-times. Each run-time is associated with a corresponding dryer module. The controller is further operable to direct operation of each dryer module based on its run-time by modifying the temperature set-point of the dryer module.

Abstract: An impact tool is provided with vibration isolators to reduce vibrations felt by the operator gripping the handle of the tool. The impact tool has a hammer and an anvil that impact against each other during use. The impacts create undesirable vibrations in the tool housing and noise in the work area. The isolators are useful in minimizing such vibrations and noise.

The anvil includes an output shaft rotatable about the axis, a plurality of anvil jaws extending from the axis, and a flange fixedly connected to an end of the output shaft and extending radially from the axis, wherein the flange supports the plurality of anvil jaws, the flange extending over the plurality of anvil jaws. The anvil includes a magnet attached to the flange opposite to the plurality of anvil jaws. An anvil angle sensor is configured to read and interpret magnetic flux changes of the magnet and determine the position of the anvil rotating about the axis.

Abstract: A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.

Abstract: A compressor system includes an electric motor having a rotatable output shaft extending from either end thereof. The compressor system further includes multiple compression stages fluidly coupled to one another in series and mechanically connected to the output shaft. The first compressor stage includes two split impellers with each impeller discharging approximately one half of the fluid flow at a desired pressure to the second compressor stage.

Abstract: In at least one illustrative embodiment, a power tool may comprise an electric motor comprising a rotor configured to rotate about an axis, a stator assembly including at least three windings arranged around the rotor, and at least three lugs affixed to the stator assembly, where each of the lugs is electrically coupled to one or more of the windings. The lugs may all be arranged to one side of a plane that passes through the axis. The power tool may further comprise at least three electrical wires, where each of the electrical wires is removably coupled to one of the lugs, and a control circuit configured to supply electrical power to the windings, via the electrical wires and the lugs, to drive rotation of the rotor about the axis.

Abstract: A compressor system can include a lubricant injection system useful to supply lubricant to an airend. The compressor system can include a variable lubricant flow valve which can be regulated by a controller on the basis of operating conditions of the compressor system. In one form the compressor system also includes an oil separator and/or an oil cooler with or without a thermal control valve. The controller can have one or more modes of operation, including a mode in which the controller regulates the flow of lubricant to the airend to increase an internal flow area of the valve when the airend is operated at an unloaded or loaded condition. In some forms the controller can regulate the lubricant flow valve and/or the thermal control valve and/or the lubricant cooler.
