Abstract
A throttle controlled induction passage assembly is shown as having a body with an induction passage formed through the body and a throttle shaft extending transversely of the induction passage and carried by the body, the throttle shaft having an axis of rotation about which the throttle shaft is rotatable, a throttle valve is carried by the throttle shaft for rotation therewith, and an abutment arrangement for preventing the throttle shaft and throttle valve from experiencing undue movement relative to the induction passage in both directions along the axis of rotation; a suitable thrust bearing is provided to permit application of the body and shaft in any position.
Claims17
A throttle controlled induction passage assembly comprising body means, induction passage means formed through said body means, throttle shaft means extending transversely of said induction passage means and carried by said body means, said throttle shaft means having an axis of rotation extending longitudinally thereof, throttle valve means carried by said throttle shaft means for rotation therewith generally within said induction passage means about said axis of rotation, abutment means for at least limiting movement of said throttle shaft means in both directions along said axis of rotation, wherein said abutment means comprises an abutment member fixedly secured to said body means, and flange-like surface means carried by said throttle shaft means, said abutment member and said flange-like surface means being juxtaposed to each other whereby said abutment member is in the path of movement of said flange-like surface means in a direction along said axis of rotation.
A throttle controlled induction passage assembly comprising body means, induction passage means formed through said body means, throttle shaft means extending transversely of said induction passage means and carried by said body means, said throttle shaft means having an axis of rotation extending longitudinally thereof, throttle valve means carried by said throttle shaft means for rotation therewith generally within said induction passage means about said axis of rotation, abutment means for at least limiting movement of said throttle shaft means in both directions along said axis of rotation, wherein said abutment means comprises an abutment portion fixedly carried by said body means, and flange-like surface means carried by said throttle shaft means, said abutment portion and said flange-like surface means being juxtaposed to each other whereby said abutment portion is in the path of movement of said flange-like surface means in a direction along said axis of rotation.
A throttle controlled induction passage assembly comprising body means, induction passage means formed through said body means, throttle shaft means extending transversely of said induction passage means and carried by said body means, said throttle shaft means having an axis of rotation extending longitudinally thereof, throttle valve means carried by said throttle shaft means for rotation therewith generally within said induction passage means about said axis of rotation, and abutment means for at least limiting movement of said throttle shaft means in both directions along said axis of rotation, wherein said abutment means comprises an annular groove formed in said throttle shaft means, and an abutment portion fixedly secured to said body means and closely received within said groove.
A throttle controlled induction passage assembly comprising body means, induction passage means formed through said body means, throttle shaft means extending transversely of said induction passage means and carried by said body means, said throttle shaft means having an axis of rotation extending longitudinally thereof, throttle valve means carried by said throttle shaft means for rotation therewith generally within said induction passage means about said axis for rotation, and abutment means for at least limiting movement of said throttle shaft means in both directions along said axis of rotation, wherein said abutment means comprises an annular groove formed in said throttle shaft means, said annular groove comprising axially spaced first and second generally radiating surface means, and wherein said abutment means further comprises an abutment portion fixedly secured to said body means and closely received between said first and second generally radiating surface means.
A throttle controlled induction passage assembly comprising body means, induction passage means formed through said body means, throttle shaft means extending transversely of and through said induction passage means and being carried by said body means, said throttle shaft means having an axis of rotation extending longitudinally thereof, throttle valve means fixedly carried by said throttle shaft means for rotation therewith generally within said induction passage means about said axis of rotation, said induction passage means comprising induction passage surface means, wherein said throttle shaft means in extending transversely through said induction passage means passes through first and second openings formed in said induction passage surface means, wherein said first and second openings are in axial alignment with each other and generally at opposite sides of said induction passage means, wherein said throttle valve means is fixedly carried by said throttle shaft means in a manner whereby first and second generally opposite portions of said throttle valve means are respectively juxtaposed to said first and second openings and first and second portions of said induction passage surface means respectively adjacent to and in the vicinity of said first and second openings, and abutment means for at least limiting movement of said throttle shaft means and said throttle valve means in both directions along said axis of rotation, such a limitation of movement of said throttle shaft means along said axis of rotation being to the degree whereby said first and second generally opposite portions of said throttle valve means are prevented from striking said first and second portions of said induction passage surface means respectively.
A throttle controlled induction passage assembly comprising body means, induction passage means formed through said body means, throttle shaft means extending transversely of said induction passage means and carried by said body means, said throttle shaft means having an axis of rotation extending longitudinally thereof, throttle valve means fixedly carried by said throttle shaft means for rotation therewith generally within said induction passage means about said axis of rotation, and abutment means for at least limiting movement of said throttle shaft means and said throttle valve means in both directions along said axis of rotation, said abutment means being effective to prevent said throttle valve means from striking said induction passage means in both directions along said axis of rotation.
