Abstract
This invention relates to a vacuum controlled apparatus to be placed between the foot accelerator of a vehicle and a carburetor of an internal combustion engine to regulate the opening of a throttle on the carburetor to maintain a relatively high vacuum in an internal combustion engine for better efficiency. The apparatus additionally effects gasoline savings and restricts the emission of pollutants into the atmosphere through the auto exhaust system. There is a housing containing a vacuum seal means generally controlled by the vacuum from the manifold of an internal combustion engine through an appropriate take-off. Additionally, spring means is associated with and co-act with the seal means to assist in the controlled opening of the throttle.
Claims4
A vacuum subjugated accelerator apparatus for use with an internal combustion engine interposed in control linkage between a foot accelerator and carburetor throttle for modulating the flow of gasoline to said carburetor and in turn achieving an optimum vacuum within an intake manifold of said engine for motor efficiency and gas savings comprising:
- an annular housing having forward and rearward ends and a horizontal axis, said housing including an end wall closing said forward end of said housing;
- a removable cap sealing said rearward end of said housing, said cap having a bore extending therethrough on the horizontal axis of said housing;
- said housing, end wall and cap means, defining a vacuum chamber;
- coupling means associated with said end wall receiving a portion of said control linkage extending directly to said throttle of said carburetor whereby horizontal movement of said housing will impart direct opening and closing of said throttle;
- a vacuum port extending through said end wall communicating with said vacuum chamber adapted to receive tubular means extending from said intake manifold of said engine to said vacuum port to create a vacuum within said vacuum chamber;
- a slidable disc rod extending from within said chamber through said bore of said cap means axially aligned on said housing axis, said disc rod coupled to a portion of said control linkage extending directly to said foot accelerator whereby foot depression of said accelerator will impart direct rearward axial movement of said slidable disc rod, said disc rod including an enlarged head portion within said vacuum chamber;
- annular flexible disc seal means mounted on said slidable disc rod with the central portion of said flexible disc bearing against said enlarged head of said disc rod;
- a disc plate mounted on said disc rod rearwardly of said flexible disc, said plate being dished with a periphery thereof in contact with said flexible disc biasing said flexible disc in a concave position toward said front wall;
- spring means including a portion locking said disc plate against said flexible disc and additionally extending rearwardly therefrom toward said cap means;
- said flexible disc seal being adapted to be further peripherally curved away from the annular interior of said housing toward said end wall when a higher vacuum is produced through said vacuum port whereby drag on said flexible disc and in turn said disc rod and linkage extending to said accelerator is created yet said disc rod and flexible disc seal being movable from said end wall toward said cap means without directly affecting the opening of said throttle and said flexible disc seal yieldably returnable to a position wherein there is partial contact between said flexible disc and said end wall in an optimum position whereby direct movement of said control linkage and vacuum subjugated accelerator means can be achieved.
A vacuum subjugated accelerator apparatus for use with an internal combustion engine interposed in control linkage between a foot accelerator and carburetor throttle for modulating the flow of gasoline to said carburetor and in turn achieving an optimum vacuum within an intake manifold of said engine for motor efficiency and gas savings comprising:
- an annular housing having forward and rearward ends and a horizontal axis, said housing including an end wall closing said forward end of said housing;
- a removable cap sealing said rearward end of said housing, said cap having a bore extending therethrough on the horizontal axis of said housing;
- said housing, end wall and cap means, defining a vacuum chamber;
- coupling means associated with said end wall receiving a portion of said control linkage extending directly to said throttle of said carburetor whereby horizontal movement of said housing will impart direct opening and closing of said throttle;
- a vacuum port extending through said end wall communicating with said vacuum chamber and tubular means extending from said intake manifold of said engine to said vacuum port;
- vacuum subjugated disc means mounted in said chamber and including a projection extending along the axis of said housing rearwardly through said bore of said cap, said vacuum subjugated disc means axially moveable independently of said housing yet adapted to be yieldably lockable to said end wall by a vacuum created through said vacuum port whereby said housing and said vacuum subjugated disc means can be moved as an integral unit assuring throttle control to effect a high vacuum in said manifold;
- coupling means associated with said projection receiving a portion of said control linkage extending to said foot accelerator, whereby excessive depression of said foot accelerator may impart axial movement to said vacuum subjugated disc means and overcome said vacuum thereby creating said independent movement of said subjugated disc means without affecting the vacuum created in said manifold,
- said vacuum subjugated disc means further includes an annular flexible disc with a peripheral edge and wherein said disc is dish-shaped and the concave surface faces said end wall and said peripheral edge engages the wall of said chamber, and
- wherein a dish-shaped disc plate is mounted on said projection rearwardly of said flexible disc biasing said flexible disc in said dish shape.
