Abstract:
A pump assembly having an air motor includes a valve connected to a motive fluid inlet of the air motor. The valve shifts between a first position, in which a flow of motive fluid is directed into a pilot port, through a two way pilot conduit and into a pilot chamber portion, and a second position, in which the flow of motive fluid is inhibited from flowing into the pilot port through the two way pilot conduit and into the pilot chamber portion, and in which fluid in the pilot chamber portion flows out through the two way pilot conduit and is directed by the valve to exhaust. The valve is connected to a programmable logic controller, so that the valve is shifted between the first position and the second position in response to the programmable logic controller.
Abstract:
The present invention provides methods and systems for a rotary impact device having an annular exterior surface for use with an impact wrench for providing torque to a fastener. The rotary impact device includes an input member having an input recess for receiving the anvil of the impact wrench, an output member having an output recess for receiving the fastener, and an inertia member. The inertia member is stationary and positioned on the exterior surface of the rotary impact device for increasing the torque applied to the fastener.
Abstract:
An air motor for a pump assembly including a drop tube communicating between an upper chamber port and a top plate port and including a longitudinal axis that is at an angle of between about 0° and 10° with respect to each of the upper chamber longitudinal axis and the top plate port longitudinal axis. The drop tube has a substantially constant internal diameter, a first generally bulbous end, a second generally bulbous end, and first and second slots defined in the respective first and second bulbous ends. First and second seals are positioned in the respective first and second slots, and the first and second seals air-tightly seal an outer surface of the drop tube within the upper chamber port and the top plate port.
Abstract:
A gas compression system includes a compressor operable to discharge a mixed flow of gas and lubricant, a separator tank including an opening having a first face, and a separator element including a disk portion having a second face and a third face. The separator element is positioned at least partially within the opening and is operable to separate at least a portion of the lubricant from the mixed flow of gas and lubricant. A lid is coupled to the separator tank and includes a fourth face. A one-piece seal ring is coupled to the disk and is compressed between the lid, the disk, and the separator tank to define a first airtight seal between the first face and the second face and a second airtight seal between the third face and the fourth face.
Abstract:
A dryer operable to separate a portion of an entrained liquid from a flow of gas includes a pressure vessel operable to contain the flow of gas and entrained liquid within the pressure vessel at a full operating pressure. The pressure vessel including a gas inlet, a gas outlet, and a drain positioned at a bottom of the pressure vessel. A precooler/reheater is positioned within the pressure vessel to receive and cool the flow of gas and the entrained liquid from the inlet and an evaporator is positioned within the pressure vessel to receive and cool the flow of gas and the entrained liquid from the precooler/reheater. A separator is positioned to receive the flow of gas and the entrained liquid from the evaporator. The separator is operable to separate the flow of gas and the entrained liquid into a flow of substantially dry gas and a liquid. The liquid collects in the bottom of the pressure vessel, and the flow of substantially dry gas flows upward through the precooler/reheater to heat the flow of substantially dry gas and out the gas outlet. A drain valve is movable between an open position and a closed position in response to the quantity of liquid within the bottom of the pressure vessel. The liquid in the bottom of the pressure vessel exits via the drain when the drain valve is in the open position.
Abstract:
A ratchet wrench has a handle (12) and a ratchet housing (18) that both extend along a first axis (A). A drive body (62) is connected for rotation relative to the ratchet housing about a second axis (B), perpendicular to the first axis. A yoke (40) substantially encircles the body and is connected to the ratchet housing and a direction selector (76) is coupled to the drive body (62) and extends along the second axis. The direction selector is rotatable about the second axis with respect to the drive body between a first position, in which the yoke is fixed for counterclockwise rotation with the drive body about the second axis, and a second position, in which the yoke is fixed for clockwise rotation with the drive body about the second axis. A direction actuator (42) is connected to the direction selector for rotation about the first axis to move the direction selector between the first and second positions.
Abstract:
A lock assembly including a body, at least one locking member and a length of lock material with two free ends and at least one leg attached to one of the free ends, each leg configured to be engaged by a respective locking member. The locking members are separately actuable such that each leg may be removed from the lock body independent of any other legs. A bracket assembly for connecting a lock assembly to a bicycle or the like. The bracket includes a bracket body with a strap that is secured via a pivotal buckle. The bracket body includes at least one flange configured to slidably engage a groove provided along the lock assembly.
Abstract:
A tool housing which in one aspect includes a body (52) defining a head portion (53) with a handle portion (54) depending therefrom to define a forward (55) and/or a rear (57) junction. A metal reinforcing member (70) is configured to span along an inside surface of the body from the head portion to the handle portion such that the reinforcing member bridges either the forward or rear junction. In another aspect, the tool assembly comprises a tool housing body, a motor (100) positioned within the tool body housing, a drive mechanism (120) connected with the motor to define a unitary motor/drive mechanism assembly, and at least one elastic isolating member (130) extending about a portion of the motor/drive mechanism assembly such that the motor/drive mechanism assembly is elastically isolated relative to the housing body.
Abstract:
A gas compression system is operable to deliver a flow of compressed gas to a point of use. The gas compression system includes a compressor that is operable to produce a flow of compressed gas at a first pressure, a motor operable to drive the compressor at a compressor speed, and a gas treatment member positioned to receive the flow of compressed gas from the compressor and deliver the flow of compressed gas to the point of use at a second pressure. A controller is operable to vary the compressor speed in response to a difference between the first pressure and the second pressure.
Abstract:
A multi-stage fluid compression system includes a first centrifugal compressor stage having a first inlet and a first outlet and a second centrifugal compressor stage having a second inlet and a second outlet. The second inlet receives a flow of compressed fluid from the first outlet. A first variable-speed motor is coupled to the first centrifugal compressor stage and is operable to drive the first centrifugal compressor stage at a first speed. A second variable speed motor is coupled to the second centrifugal compressor stage and is operable to drive the second centrifugal compressor stage at a second speed. The first speed and the second speed are each independently variable.
