Definitions

  • ABSTRACT An air cleaner for an internal combustion engine embodying a centrifuging action to direct dust particles into a duct for exhaust to the atmosphere having separated the same for air directed into a chamber of increasing size for reduction of the velocity of said air as it approaches the vents through which it is drawn for passage to said engine.
  • SHEET 2 BF 2 AIR CLEANING STRUCTURE This invention relates to an air cleaner for an internal combustion engine embodying a centrifuging action to separate dust particles from the air and to provide for a reduction in the initial velocity of clean air as it approaches the vents through which it is drawn for passage to the air intake of said engine.
  • the structure herein comprises a cylindrical housing having a tangential deflection plate directing air inwardly setting up a centrifuging action for separation of dust particles into a radially narrow duct at the inner side of the outer wall of said housing which duct exhausts to the atmosphere and clean air by passes said duct and moves into a chamber portion of increasing size to reduce its velocity in approaching vents through which it is drawn into a passage running to the engine.
  • FIG. 1 is a view in horizontal section taken on line l-l of FIG. 2 as indicated;
  • FIG. 2 is a view in vertical section taken on line 2-2 of FIG. l as indicated;
  • FIG. 3 is a broken view in perspective on an enlarged scale with some portions thereof being removed.
  • the air cleaning device which comprises the subject matter of the invention herein consists of a cylindrical outer housing 112 having an outer wall 13, a removable top wall or cover 15, a chamber 16 therein and a bottom wall 19.
  • a means for providing clean air to the engine which comprises an inner housing formed as a tubular member having an outer wall 26, a top wall 27 a second wall 28 spaced below said wall 27, and a chamber or passage 29 therein. Said upper wall is tapped to receive a stud bolt 30 disposed through an accommodating aperture in said cover 15. Said tubular member 25 is disposed within said outer housing 12 to be in an axially off center position with respect thereto as will be further described. Said tubular member extends downwardly of said bottom wall 19 through an accommodating opening 32 therein and preferably is secured thereto.
  • a helical flange 34 Spaced upwardly of said bottom wall 19 is a helical flange 34 extending radially between said outer wall 13 and said tubular member 25 defining one revolution about said tubular member and having an upper end portion 36 in vertical alignment with its lower end portion 37 defining an outlet 40 therebetween as will be further described.
  • Said slotted opening 42 is further defined by said walls 43 and 44.
  • a wall 47 extends forwardly tangentially to said housing 12 commencing with said side wall 43 and extending forwardly sufficiently to overlie said slotted opening 42 forming a deflector and thus it defines an inlet passage 50 taken with the housing 12.
  • the forward or free end of said wall 47 carries at right angles thereto a slotted flange 49 and an adjacent opposite portion of said housing 12 has a vertical projecting boss 53 which has formed thereon a corresponding slotted flange 54 projecting outwardly thereof.
  • screen 60 Carried by said oppositely disposed flanges 49 and 54 and slidingly disposed therein is screen 60. It will be understood that said screen may be otherwise secured.
  • the top wall or cover 15 above mentioned is of a configuration to overlie the housing 12 and to have a portion thereof extending to overlie the upper portion of said wall 47 and said screen 60.
  • Said cover 15 has a slot 15a in its bottom side to receive therein and seat the upper edge portions of said housing, said wall and said screen.
  • a duct 70 comprising a passage is formed by a wall 71 spaced radially inwardly a short distance from said outer housing wall 13.
  • Said duct has a top wall 72.
  • Said duct declines in height having its top wall define a helical path about the inner side of said wall 13.
  • Said helical flange 32 forms the bottom wall of said duct.
  • Said duct terminates with its discharge end portion 73 extendingjust within said discharge outlet 40 as indicated in FIG. 3.
  • an exhaust vent 80 Extending outwardly of said housing 12 from said discharge outlet 40 is an exhaust vent 80 which reduces outwardly in transverse dimension and is shown here carrying at its outer end an exhaust fan member 81 which will draw and exhaust air from said housing as will be described hereinafter.
  • the air cleaner herein is intended for use with an internal combustion engine as in connection with a tractor such as may be used for farming purposes or for hauling trailers. Such vehicles commonly have a stack providing air passage to the carburetion system of the engine. The air cleaner will be mounted onto the upper end of the stack in an appropriate manner such as by having the lower end portion of the tubular member 25 slipped onto the upper portion of the stack to be clamped thereon.
  • the action of the engine will draw air into and through the housing 12.
  • the exhaust fan member 81 will provide for sufficient and positive movement of air to pass through the housing 12 irrespective of the engine speed.
  • the air cleaner will operate at a point of maximum efficiency even during the times when the engine may be idling or operating at low speeds.
  • the wall 47 in forming a deflector initiates a centrifugal action which carries the dust particles of the air entering the slot opening 42 along the inner side of the wall l3'and into duct 70.
  • the overlying flange 74 confines the upper reach of entering air directing it toward said duct 70.
  • the air moving through said duct 70 is tapered downwardly to the exhaust end portion 73 thereof to be exhausted to the atmosphere through the exhaust passage or vent 80.
  • the helical bottom wall 34 provides a downward sloping passage for the exhaust of any dust particles which come to rest thereupon. Said wall 34 also pro vides for the exhaust of dust particles along the bottom of said passage 70.
  • An air cleaner for an internal combustion engine having in combination a cylindrical housing formed with an outer wall, an inner wall spaced from said outer wall forming a duct of narrow radial width within said housing,
  • said duct decreasing in height from its inlet end toward its outlet end and having an overlying top wall
