Abstract: An apparatus and method for latching a hammer of an impact tool, the hammer being displaceable along a cam shaft between a latched or retracted position and an impact position at which the hammer impacts an anvil. The apparatus can include one or more latching bodies, a portion of the one or more latching bodies being positioned within the hammer groove when the hammer is at the latched position, and removed from the hammer groove when the hammer is to be released from the latched position. The apparatus can also include an actuator sleeve that is configured to retain at least the portion of the one or more latching bodies within the hammer groove when the actuator sleeve is at the first position, and accommodate removal of the portion of the latching bodies from the hammer groove when the actuator sleeve is at a second position.

Abstract: A filter system can include a replaceable filter cartridge having a spinner element structured to swirl a mixed flow of compressible fluid and oil, as well as an end cap used to enclose an open interior of a filter media of the filter cartridge. The filter cartridge can be configured to interface with and be supported by a mesh holder. A housing can be attached over the filter cartridge to enclose the system and create a flow path for a mixed flow of compressible fluid and oil. The replaceable filter cartridge can be constructed of materials suitable for disposal in a waste incineration process. The mesh holder can be inserted on a combo-block and secured in place by a compression fitting. A stand pipe can extend into the interior of the filter media and be coupled with a central passage of the mesh holder.

Abstract: A power tool is provided that, in one version, includes a front housing that supports an output drive, and a back cap located opposite the front housing. The back cap receives at least one fastener of the plurality of fasteners. A motor housing supports a motor and is located between the front housing and the back cap. The motor includes a rotor that is configured to rotate about a motor axis to drive rotation of the output drive. The fastener is disposed through the back cap, and secures to the front housing coupling the front housing, the motor housing, and the back cap together.

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: An impact tool is provided which includes a drive source configured to rotate an output drive. A hammer is movable in a first direction to apply a rotational impact force on an anvil which rotates the output drive. A first hammer angle sensor set to a first signal channel and located proximate to a surface of the hammer. A plurality of regularly spaced targets are located on the surface of the hammer. Each of the plurality of regularly spaced targets are detectable by the first hammer sensor. And detection of one or more of the plurality of regularly spaced targets by the first hammer sensor indicates movement of the hammer.

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 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.

Abstract: A hydrodynamic bearing in the form of a flex pad bearing includes configurations structured to change a bearing characteristic. One form of the bearing includes a nonlinear back wall that includes a circular arc and a transition, where the back wall extends radially outward of a ligament. The bearing can include an opening for the deposit of a weighted mass, wherein the opening can threadingly receive a threaded weighted mass. In one form a sidewall that includes the back wall segment can have an average outer radius which determines a thickness of the flex pads.
