Abstract:
A hand-held power tool is provided that includes a motive source, a user interface, and one or more sensors. The motive source includes a printed circuit board (PCB) configured to support electrical components of the motive source. The user interface is movable between a plurality of mode positions to select one of a plurality of operational modes of the motive source. And one or more sensors are mounted on the PCB and are configured to detect the plurality of mode positions of the user interface.
Abstract:
A hand-held power tool is provided that includes a housing assembly to support a motor. An output spindle protrudes from an output end of the housing assembly such that the output spindle rotates in response to a rotation of the motor. A user interface is located at the housing assembly opposite the output spindle. The user interface is configured to select one of a plurality of modes of operation of the hand-held power tool to regulate power supplied to the motor.
Abstract:
A system is disclosed wherein a pressure pulse dampener is in fluid communication with a compressed fluid. The pulse dampener being operable for reducing pressure pulsations within the fluid. In some embodiments a check valve can be in fluid communication with the pulse dampener to prevent reverse flow of the compressed fluid.
Abstract:
An induction rotor assembly having an induction cage that is formed using a combination of liquid and solid materials. The first and second end plates of the induction cage may be fabricated before the casting of the conductors of the induction cage. According to certain embodiments, the first and second end plates may be assembled with first and second molds and a rotor core to form a casting assembly. A liquid casting material may be injected into the casting assembly, wherein the liquid casting material may solidify within one or more core passageways of the rotor core, thereby forming the conductors of the induction cage. The first and second end plates may also include flow channels that may be configured to facilitate the flow of the liquid casting material in the casting assembly, and increase the area of contact between the liquid casting material, when solidified, and the end plates.
