Abstract: Illustrative embodiments of impact tools with impact mechanisms rigidly coupled to electric motors are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism, an electric motor, and a control circuit. The impact mechanism may comprise a hammer and an anvil, the hammer being configured to rotate about a first axis and to periodically impact the anvil to drive rotation of the anvil about the first axis. The electric motor may comprise a rotor that is rigidly coupled to the impact mechanism, the electric motor being configured to drive rotation of the hammer about the first axis. The control circuit may be configured to supply a current to the electric motor and to prevent the current from exceeding a threshold in response to the hammer impacting the anvil.

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: An impact wrench comprises dynamically tuned drive components, such as an anvil/socket combination. The drive components are dynamically tuned in view of inertia displacement, as well as stiffness between coupled components, and with regard to impact timing associated with clearance gaps between the component parts.

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 fluid compressor system configured to supply a compressed working fluid including at least a first air-end and a second air-end, a first and second intercooler, and a coolant circulation system having at least one throttle valve. The first and second intercoolers are configured to cool the compressed working fluid delivered by the first and second air-ends of the fluid compressor system, respectively. The coolant circulation system includes a coolant supplying header and a coolant collecting header, where the coolant supplying header supplies a coolant to the first intercooler and the second intercooler, and the coolant collecting header collects the coolant from the first intercooler and the second intercooler. The at least one throttle valve regulates a coolant flow discharged by one of the first intercooler or the second intercooler prior to entering the coolant collecting header.

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.

CPC classification number: G05D16/2022 , F15B15/14 , G05D16/2033
Abstract: A fluid compressor system having a pneumatic inlet/blowdown valve assembly that utilizes pneumatic pressure and vacuum available in the fluid compressor system for the actuation of an inlet valve and a blowdown valve. The actuation of the inlet valve and the blowdown valve is synchronized via a piston-cylinder actuator having a first piston and a second piston axially connected. The pneumatic blowdown/inlet valve assembly uses a first stage vacuum pressure to actuate the first piston and the second piston from an idle state where the inlet valve is closed to stop a flow of working fluid into the fluid compressor system and the blowdown valve is open to depressurize the fluid compressor system to an actuated state where the inlet valve is open to allow the flow of working fluid into a first airend and the blowdown valve is closed to allow a pressure buildup in the fluid compressor system.

Abstract: A diaphragm structured for use in a diaphragm pump useful to pump a working fluid includes a first non-planar layer and a second non-planar layer. The second non-planar layer is independent from the first non-planar layer, but engaged to the first non-planar layer so that the first non-planar layer and the second non-planar layer form a closed space therebetween and travel together while flexing in an intake direction or a discharge direction within a pumping assembly of a diaphragm pump.

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: Integrally geared centrifugal compressor systems are described that include eccentric cartridges that house bearings and seals to maintain rotor concentricity for a variety of pinons integrated in a fixed gearbox design to provide multiple impeller speeds with a single gearbox design. In an aspect, a system includes, but is not limited to, a pinion configured to be rotated by a bull gear about a rotational axis; a rotor coupled to the pinion; and an eccentric cartridge configured to house a bearing assembly through which the rotor extends to support rotation of the rotor, the eccentric cartridge having an outer surface and an inner surface, wherein the inner surface is eccentric relative to the outer surface to align the rotational axis with a center axis of the bearing assembly.
