  • Patent number: 6655925
    Abstract: A manifold assembly is provided for controlling and distributing compressed air from an air compressor to one or more air powered tools. The manifold assembly may be attached directly to the air compressor, or, alternately, removed from the air compressor and coupled thereto via an air conduit, e.g., an air hose or the like, so that the manifold assembly can be used at locations remote from the air compressor.

  • Patent number: 6648603
    Abstract: An engine idle controller for an engine driven pressure washer. The pressure washer delivers high pressure water from a pump through the idle controller to a conventional wand which includes a manually operated, normally closed flow control valve and a spray nozzle. When the wand valve is opened, a resulting pressure drop between two chambers in the flow controller acts on a piston to move the engine throttle to a full throttle position. When the wand valve is closed, the pressures in the chambers equalize and the piston is moved to a position to set the engine throttle to an idle position.

  • Patent number: 6558135
    Abstract: A two stage reciprocating piston oil free air compressor having an improved service interval. In a first stage, a first wobble piston is reciprocated in a first cylinder to compress ambient air to an intermediate pressure. In a second stage a second wobble piston is reciprocated in a second cylinder to compress the intermediate pressure air to a desired high pressure. Each wobble piston is provided with a seal which seals to the adjacent cylinder walls as the piston reciprocates and rocks. The stroke of the higher pressure second stage piston is less than the stroke of the lower pressure first stage piston to increase the operating life of the second seal, preferably to substantially the same operating life as the first seal.

  • Patent number: 6541718
    Abstract: A full power switch assembly for a portable generator that is capable of instantly communicating the presence and operation of a full power switch to the user is disclosed. The full power switch assembly includes a first outlet for supplying electrical power having a first voltage (e.g., 120 VAC), a second outlet for supplying electrical power having a second voltage (e.g., 240 VAC), and a switch including a selector. The selector is movable from a first position to a second position for causing the first outlet to be capable of supplying electrical power up to a maximum power level. Movement of the selector between the first position and the second position further causes indicia to be displayed for indicating whether the first outlet is capable of supplying electrical power up to the maximum power level.
