Definitions
- Objects of the invention are to provide for restriction variation in an improved manner, with simple, reliable, inexpensive structure easily adapted to existing air cleaner design.
- the invention features a supplementary air inlet through the air cleaner cover, and a second cover adjacent the first and arranged to move between a first position in which air is allowed to pass through the supplementary inlet and a second position in which the second cover impedes such supplementary air flow.
- the second cover is annular, is sealed to the main cover at radially spaced zones to define a vacuum compartment, and has a valving portion extending radially outward of the outermost seal zone to overlie a ring of supplementary inlet holes; a vacuum source is connected to the vacuum compartment to control the spacing between the two covers; and a sealing gasket is mounted radially outward of the secondary inlets to act as a valve seat for said valving portion and hence to seal between the covers when high vacuum conditions in the compartment draw down the second cover, thereby shutting off all air supply to the supplementary inlets.
- FIG. 1 is a plan view of an air cleaner, partially broken away;
- FIG. 2 is a sectional view taken along 2-2 of FIG. 1.
- carburetor air cleaner is of conventional design to the extent that it includes cylindrical filter 12 supported around perforated center-tube 14 in housing 16 having a main air inlet tube 18 and an axial outlet 20.
- Cover 22 is held on threaded shaft 24 by wing nut 26, and has downwardly and outwardly sloping portions 28 and 30 between which are horizontal portion 32 and upwardly sloping portion 33.
- Gasket 34 is fixed in the outer rim 36 of the cover and seals against outer wall 38 when the cover is tightly in place.
- a ring of supplementary air inlet holes 40 is provided in sloping cover portion 30.
- a second generally annular cover 50 of outside diameterless than that of cover 22, is mounted on top of cover 30, with its inner periphery 52 adhesively sealed to cover 30, and with a resilient gasket 54 adhesively sealed between cover portion 32 and corresponding horizontal portion 56 of cover 50.
- a sealed compartment 60 is thus formed between the two covers, and is connected to the engine manifold vacuum source (shown schematically at 61) by tube 62. Radially outward of gasket 54 cover 50 extends generally parallel to cover portion 30, over inlets 40, to above sealing gasket 64 fixed between rim 36 and openings 40.
- engine vacuum manifold pressure determines the pressure in vacuum compartment 60.
- cover 50 At low pressures (i.e., high suction) cover 50 will be drawn toward cover 22 (see phantom position in FIG. 2) until cover 50 seals against gasket 64, preventing any air flow through inlets 40.
- cover 50 moves away rom gasket 64 to allow air to flow through inlets 40, supplementing and mixing with the air flow through inlet 18, thereby decreasing the total restriction to carburetor air flow provided by the air cleaner.
- an air cleaner for a carburetor having a filter mounted in a housing, a cover for the housing clamping means for securing the cover to the housing, a main air inlet into the housing upstream of said filter, and an outlet downstream of said filter, that improvement comprising a portion of said cover having a supplementary air inlet into said housing upstream of said filter,
- a second cover overlying said first-mentioned cover adjacent said supplementary inlet, said covers being sealed to each other at radially spaced seal zones, said zones defining a vacuum compartment between said covers, said second cover having a valving portion extending radially outward of the radially outermost of said seal zones to overlie said supplementary inlet, and
- said compartment being connected to and communicating with a vacuum source to control the spacing between said covers and hence the position of said valving portion relative to said supplementary inlets.
- the device of claim 1 further comprising a sealing gasket mounted radially outward of said secondary inlet and providing a valve seat for said valving portion of said second cover, to seal between said covers when high vacuum conditions in said vacuum compartment draw down said second cover, thereby shutting of all air supply to said supplementary inlet.
- said second cover is sealed at its inner periphery to said first-mentioned cover and has portions extending generally parallel to said portions of said firstmentioned cover, but spaced therefrom, said second cover having a horizontal portion, aligned above said first-mentioned horizontal portion,
- said supplementary inlet is a ring of openings in the radially outermost of said downwardly and outwardly sloping portions of said first-mentioned cover, and
- said second cover has an outside diameter less than that of said first mentioned cover.
