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: A power tool having a handle extending along a longitudinal axis, wherein the handle is configured to house a motor. A ratchet head is connected to a first end of the handle. The ratchet head supports an output shaft having a drive square or bit that is driven by the motor. The ratchet wrench includes an application-targeted lighting system disposed around a periphery of the handle that illuminates the ratchet head and a workpiece below the output shaft. The application-targeted lighting system may include an array of Chip-On-Board LED lights. The application-targeted lighting system illuminates the workspace in applications where socket extenders and/or deep sockets are used with the ratchet wrench.

Abstract: A dynamic compressor includes an impeller having impeller vanes disposed around a hub, a shroud, and a diffuser having a shroud surface adjacent to the shroud and a hub surface adjacent to the hub, wherein the diffuser is circumferentially disposed around the impeller. The diffuser includes a plurality of diffuser vanes extending from the hub surface to the shroud surface, each having a vane leading edge and a vane trailing edge. The diffuser includes a centrifugal acceleration stabilizer ring formed in the shroud surface located in a vaneless region defined between an impeller trailing edge and the vane leading edge. The centrifugal acceleration stabilizer ring stabilizes the flow of the fluid by changing the circumferentially-flowing high velocity fluid flow exiting the impeller into a radially-flowing high velocity fluid flow before entering the diffuser, improving the efficiency of the dynamic compressor.

Abstract: The present disclosure is directed to a screw compressor system having a compressor housing with a pair of screw rotors rotatably supported within a compression chamber. Lubricant is injected into a compression chamber at a first volume ratio and at a second volume ratio greater than the first volume ratio to increase the sealing and lubrication between the screw rotors and rotor bores in the compressor housing as well as to increase heat transfer from a compressed working fluid in the compression chamber.

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: 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.
