Abstract: The disclosure concerns a separator for removing broken engine parts and other debris from the hot gases passing fro the exhaust manifold of an engine to the inlet of an associated turbocharger. The separator includes an annular separation chamber in which the gases are swirled by stationary vanes to effect centrifugal separation of the debris, and a cylindrical screen which filters the gases as they leave the separation chamber. The screen is mounted in cantilever fashion within the separator casing and carries, at its free end, the vanes and a deflector which directs inlet flow radially outward to the separation chamber. The vanes are freely mounted in slots formed in the screen, where they are held captive by the slot margins and the deflector, and the tips of the vanes are spaced radially from the surrounding casing of the separator.
Abstract: An assembly connectable between a compressor and reservoir, having a filter unit capable of centrifugally cooling and separating condensed moisture and other contaminants from compressed air and discharging clean air in saturated condition at the outlet temperature and pressure, the unit being connected to the compressor through an inlet valve opening when the compressor begins pumping and to the reservoir through a pressure regulator valve adjustable to open only when the air in the unit reaches a predetermined pressure, which, for minimizing the absolute moisture content of the clean air passed to the reservoir, usually will be substantially maximum reservoir pressure.
Abstract: This disclosure deals with an air cooler and cleaner which receives compressed air coming from an air compressor and removes the moisture content, lubricant oil, solid particles and other contaminants which may be entrained in the air. The air cooler and cleaner includes a tubular metal housing, an upper housing closure and a lower housing closure. Sheet metal cooling fins having housing-receiving openings and cylindrical spacer and heat-conductor collars around said openings are heat shrunk onto the housing in firm thermally conductive contact therewith, the fins being in spaced relation to each other. A swirl chamber is provided in the lower portion of the housing and a cooling chamber is provided in the upper portion of the housing. The swirl chamber has a tangential air inlet for rapidly spinning the air therein. An inverted cylindrical cup-like air director is mounted within the cooling chamber for directing the air against and along the wall of the cooling chamber in a thin layer.
Abstract: The dust collecting efficiency of a gravel bed filter system in which a plurality of filter modules receive dirty gas from and dischage backflush gas and collected dust into a plenum chamber is enhanced by continuously drawing gas from a downstream end of the plenum chamber, passing the withdrawn gas through a cyclone separator, and returning the gas to the upstream end of the plenum chamber.
Abstract: A vertically oriented, sheet metal enclosure includes a frusto-pyramidal lower section forming a hopper for separated particulate matter from an air stream which enters a middle section from a downwardly and inwardly inclined inlet duct fixed to one side of that section at the upper end, causing impingement of the airborne particles against the side of the hopper to effect a swirling action to the air stream. An array of laterally spaced, inclined baffle plates at the upper end of the middle section separates the middle section from an upper section which carries tensioned tubular filter bags. An enclosure cover defines an outlet opening feeding to a cover mounted blower.
Abstract: An air cooler and cleaner for cooling compressed-air coming from an air-compressor and for removing the moisture content thereof and for removing lubricant oil and solid particles and other contaminants which may be entrained therein. The air cooler and cleaner includes a tubular aluminum housing and an upper housing-closure and a lower housing-closure. Sheet-aluminum cooling fins having housing-receiving openings and cylindrical spacer and heat-conductor collars around said openings heat-shrunk onto the housing in firm thermally-conductive contact therewith and spacing the fins in relation to each other. A swirl-chamber in the lower portion of the housing and a cooling-chamber in the upper portion of the housing. The swirl-chamber has a tangential air-inlet for rapidly spinning the air therein. An inverted cylindrical cup-like air-director within the cooling-chamber for directing the air against and along the wall of the cooling-chamber in a thin layer.
