Abstract: A rotary power tool assembly including a hammercase an axis extending between a forward end and a rearward end, a drive mechanism housed within the hammercase, and a hammer driven by the drive mechanism to apply a rotational impact force on an anvil. 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: An impact wrench is provided with a battery to power the motor. The impact wrench provides improved portability since the impact wrench does not need to be connected to an electrical extension cord or a pneumatic hose. The output drive, motor, batteries and main handle may be aligned along the axial direction of the tool. The batteries may be located between the motor and the main handle.

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: A power tool includes a housing having a working end and a side (e.g., back side) separate from the working end, and a user interface supported by the housing and positioned on the side of the housing. The power tool can also include one or more protrusions defined by the housing proximate to the user interface and extending away from the housing for protecting the user interface from an impact on the side of the housing. A removable user interface guard for the power tool includes a body formed of an impact resistant material for protecting the user interface of the power tool from an impact at the side of the power tool, and a retention feature on the body configured to mate with a corresponding feature on the housing of the power tool to removably secure the body to the side of the housing over the user interface.

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.

Abstract: A turbocharged compressor system using an Organic Rankine Cycle system to recover waste heat from a compression process. The Organic Rankine Cycle system circulates an organic fluid through an evaporator, where the organic fluid vaporizes and is expanded in a turbine section of a turbocharger to drive a compressor section of the turbocharger. The organic fluid vapor is condensed in a condenser and is pumped to the evaporator once again for recirculation. The compressor section of the turbocharger pre-compresses a working fluid before entering an airend in a compression system. As the working fluid exits the airend, it may be delivered to the evaporator, where the waste heat from the working fluid evaporates the organic fluid flowing in the Organic Rankine Cycle system. The working fluid may also be circulated between intercoolers in multi-stage compressor systems.

Abstract: A centrifugal compressor impeller includes a plurality of blades on a front side that extend from a first axial side to an outer radial end of the impeller. The centrifugal impeller includes a back side having a nonlinear backwall. The backwall can include a flat area hear a bore of impeller, a flat area near a tip of the impeller, and a convex surface between the flat areas of the bore and the tip. In some forms the impeller further includes a concave surface between the convex surface and the tip to form an s-shape. A transition or inflection point can denote the change from convex to concave. The convex and/or concave surfaces can take any variety of forms such as constant radius sections and/or compound curves.

Abstract: A computer may display on a graphical user interface (GUI) a component library including a set of components relating to a compressed air system. The GUI may have a modeling interface for configuring a virtual model using the set of components. The computer may simulate the virtual model to determine one or more optimizations to the compressed air system. The computer may also determine the cost of implementing the compressor system optimization.

Abstract: A compressed air drying system is provided for removing moisture from compressed air. The dryer operates in two modes in response to the demand for compressed air. In a first mode of operation, a refrigeration compressor runs continuously and the speed of a condenser fan is varied to maintain a constant cooling temperature. In a second mode of operation, the refrigeration compressor runs intermittently between on and off periods. As result, the cooling temperature fluctuates during the second mode of operation.
