Abstract: An impact tool having a multiple position non-contact trigger system. The trigger system includes a trigger member having at least one magnet moveable along a plurality of non-contact sensors when the trigger member moves from a non-actuated position to a fully actuated position. The plurality of non-contact sensors sense the movement of the trigger member and output a corresponding signal to a controller. The controller may command the impact tool to perform a function from a plurality of functions based on the position of the trigger element, where each position of the trigger element may correspond to a different mode of the power tool system.

Abstract: An electro-magnetic thermal control valve (EMTCV) is configured to selectably direct and control an amount of coolant fluid to a cooler in a coolant circulation system. The EMTCV includes a valve housing defining a main chamber, an electromagnet disposed in the valve housing, and a movable sleeve disposed within the main chamber. The movable sleeve is fixedly attached to a permanent magnet adjacent to the electromagnet. When the electromagnet is energized by a current supplied by a valve control system, the electromagnet exerts a force on the permanent magnet, moving the movable sleeve is from an idle position to plurality of intermediate positions or an actuated position.

Abstract: A positive displacement roots blower can include a housing having an inlet structured to receive an incoming flow of a fluid, an outlet structured to receive an outgoing flow of the fluid, and a passage. The positive displacement roots blower can also include a pair of intermeshed rotating members supported for complementary rotation within the housing, where the rotating members and the housing form respective operating volumes there between which rotate with the rotating members. Each of the respective operating volumes has the following regions: (1) open to inlet/closed to outlet; (2) closed to inlet/closed to outlet; and (3) closed to inlet/open to outlet. The passage includes a restriction and connects to at least one of the operating volumes when the at least one of the respective operating volumes is in region (2). The restriction can be a venturi feedback connecting to the outlet.

Abstract: Methods are provided for controlling a refrigerated dryer of a gas compressor system. In an aspect, a control system, including a controller and a flow sensor, selectively operates 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: 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 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 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 cooling assembly for a power tool includes an air mover configured to be disposed within a housing assembly at a first end of a generally longitudinal enclosure proximate to a handle enclosure. The air mover is configured to direct air into the housing assembly and then generally perpendicularly to a longitudinally extending direction of the generally longitudinal enclosure. The cooling assembly also includes a duct configured to connect to the air mover and be in fluid communication with the air mover to direct air into the handle enclosure. The duct includes an inflow segment defining a first area for receiving the air from the air mover, an outflow segment defining a second area for directing the air from the air mover into the handle enclosure, and a connecting segment connecting the inflow segment to the outflow segment.
