A nozzle adapter/attachment includes features that facilitate use and protects the user from possible fluid exposure. The nozzle attachment is configured with features that both align and clamp onto an existing nozzle. In one embodiment, there are three sets of alignment and clasping features.

Nozzle adapter for 3-way liquid spray nozzle

Liquid spray nozzle

The invention provides a telescoping wand assembly for use in dispensing liquid from a container, including a trigger module extending along a longitudinal axis between proximal and distal ends. The trigger module includes a tubular handle member, a user accessible trigger positioned externally of the tubular handle member that is selectively movable between first and second positions, a hose positioned within the tubular handle member and adapted to transport liquid from the container, and a valve actuating member that is selectively, movably actuable by movement of the trigger between its first and second positions. A stationary frame assembly provides rigidity and contact points for a telescopically movable tube assembly that extends from the trigger module. A shut-off valve and nozzle are positioned at the distal end of the wand assembly and movement of the shut-off valve is controlled by the trigger and translated by way of the tube assembly.

A hand held compressed air power tool is provided with a handle that can axially rotate about an orthogonal axis perpendicular to the tool housing. Thus, the handle can rotate independently of the motor housing thereby allowing the handle to point in a different direction other than toward the point of impact. The tool utilizes a rotational coupling system that allows the handle to rotate while also allowing compressed air to be fed into, and exhausted out of, the tool via the base of the handle.

Pistol handle pulse tool

The invention is an impulse wrench that employs a fluid coupling between its anvil and hammer members. The tool includes a pulse cylinder that forms the tool's hammer and has a shaped inner surface that defines a side wall of a fluid-filled chamber. An end portion of the anvil is received within the chamber and includes two retractable vanes that sweep the pulse cylinder's inner surface when the pulse cylinder is rotating about the anvil. To achieve only a single impact per revolution of the pulse cylinder, fluid bypass channels are employed to intermittently allow fluid to pass around the vanes. In addition, the tool includes a unique torque-sensing shut-off mechanism that is engaged to the tool's motor and makes use of inertia force to actuate a power shut-off device.
