Abstract: A control system for controlling a refrigerated dryer of a gas compressor system includes a controller and a flow sensor and can be selectively operated in a power saving mode in which the controller shuts down a refrigerant compressor included in the dryer system when the flow sensor indicates that no compressed gas is flowing through the dryer. The control system uses input from a temperature sensor to determine whether to activate the compressor regardless of the flow of compressed gas through the dryer.

Abstract: A power tool is provided. The tool has a housing containing an internal drive system that drives an output member that engages a workpiece and exerts mechanical force thereupon. A force sensor and a positional sensor are operatively connected to the drive system to sense characteristic variables of the drive system during engagement of the workpiece. A light unit is positioned on a front end and a top portion of the housing so as to be able to direct light of various colors onto the workpiece. A control unit is operatively connected to the drive system and the light unit so as to control the light unit based on the characteristic variables of the drive system measured by the sensors. The light unit may illuminate a colored light on the workpiece depending on whether or not the workpiece was determined to be fastened according to predetermined specifications.

Abstract: A diaphragm pump having a crankshaft that is rotatable about a rotational axis and coupled to a piston. The piston is reciprocally displaceable within a piston cylinder along an axis of motion between suction and discharge strokes. A diaphragm housing coupled to the piston cylinder at least partially defines a pumping chamber through which fluid is pumped as the piston reciprocates. The axis of motion, which intersects a connection between the piston and the connecting rod, may not intersect the rotational axis of the crankshaft such that, relative to an arrangement in which the axis of motion does intersect the rotational axis, a peak magnitude of piston side load forces during the discharge stroke is reduced and a peak magnitude of piston side load forces during the suction stroke is increased so as to attain an improved balance between the peak magnitudes of piston side load forces of the discharge and suction strokes.

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 assembly includes a drive mechanism, a longitudinally extending housing, an electrical connection at the housing for receiving electrical energy, and an attachment mount on the housing for releasably attaching a tool accessory to the power tool assembly. The attachment mount includes electrical connections for mating electrical connectors of the tool accessory to furnish power and/or data transfer between the power tool and the tool accessory. The attachment mount includes at least one rail configured for sliding contact with at least a second rail of the tool accessory to restrict movement of the tool accessory, and a latching mechanism for releasably securing the tool accessory to the attachment mount. A tool accessory for releasably attaching to a power tool assembly includes electrical connectors for mating with electrical connections of an attachment mount, at least one rail, and a receiver for receiving a latching mechanism of the attachment mount.

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.
