Engine intake pipe arrangement for automotive vehicle

Claim 2

An engine intake pipe arrangement for an automotive vehicle comprising: an intake pipe; a support; and means for supporting and holding said intake pipe in a floating and spaced relationship on said support, said means including a springy resilient mounting member interposed in a resilient state between said intake pipe and said support enabling the intake pipe to be movable away from and toward said support, and a springy resilient fastening member connected in a stretched state between said intake pipe and support and urging said intake pipe toward said support against the resilience of said mounting member.

Claim 3

An engine intake pipe arrangement as set forth in claim 1 in which said intake pipe is rigid but has some flexibility.

Claim 4

An engine intake pipe arrangement as set forth in claim 2 further comprising an air cleaner which is rigidly mounted on a vehicle body and to which an upstream end of said intake pipe is connected.

Claim 5

An engine intake pipe arrangement as set forth in claim 3 in which the upstream end of said intake pipe is connected through a rubber duct to said air cleaner.

Claim 6

An engine intake pipe arrangement as set forth in claim 3 in which said support comprise an intake manifold to which a downstream end of said intake pipe is connected.

Claim 7

An engine intake pipe arrangement as set forth in claim 5 in which said intake pipe is at least in part formed to have a rectangle-like cross section having three straight sides and one concave side.

Claim 8

An engine intake pipe arrangement comprising an intake pipe, said intake pipe being rigid but having some flexibility and having a rectangle-like cross section with three straight sides and one concave side, a support comprising an intake manifold connected to a downstream end of said intake pipe, and means for mounting and holding said intake pipe on said support including a resilient mounting member interposed between said intake pipe and said support for mounting said intake pipe in a floating manner on said support enabling the intake pipe to be movable relative to said support, and a resilient fastening member fastening said intake pipe to said support, said mounting member including a resilient mounting ring mounted on said intake pipe in a predetermined stretched state, said mounting ring having a bridge portion spanning said concave side of said intake pipe, said intake pipe being placed on said intake manifold in such a manner that said bridge portion of said mounting ring is in contact with an upper part of said intake manifold.

Claim 9

An engine intake pipe arrangement comprising an intake pipe, said intake pipe being rigid but having some flexibility and having a rectangle-like cross section with three straight sides and one concave side, a support comprising an intake manifold connected to a downstream end of said intake pipe, and means for mounting and holding said intake pipe on said support including a resilient mounting member interposed between said intake pipe and said support for mounting said intake pipe in a floating manner on said support enabling the intake pipe to be movable relative to said support, and a resilient fastening member fastening said intake pipe to said support, said mounting member including a resilient mounting ring mounted on said intake pipe in a predetermined stretched state, said mounting ring having a bridge portion spanning said concave side of said intake pipe, said intake pipe being placed on said intake manifold in such a manner that said bridge portion of said mounting ring is in contact with an upper part of said intake manifold.

Claim 10

An engine intake pipe arrangement as set forth in claim 7 in which said mounting and holding means further have a pair of hooks in the form of projections provided to said intake manifold, and in which said fastening member comprises a resilient fastening band which is arranged adjacent said mounting ring in a manner to partly encircle said intake pipe and is hooked at the opposed ends thereof and in a predetermined stretched state of said hooks.

Claim 11

An engine intake pipe arrangement as set forth in claim 8 in which said mounting ring and said fastening band are made of rubber.

Claim 12

An engine intake pipe arrangement comprising an intake pipe, said intake pipe being rigid but having some flexibility and having a rectangle-like cross section with three straight sides and one concave side, a support comprising an intake manifold connected to a downstream end of said intake pipe, and means for mounting and holding said intake pipe on said support including a resilient mounting member interposed between said intake pipe and said support for mounting said intake pipe in a floating manner on said support enabling the intake pipe to be movable relative to said support, and a resilient fastening member fastening said intake pipe to said support, said mounting member including a coil spring mounted on said intake pipe to span said concave side thereof and in a predetermined stretched state, said intake pipe being placed on said intake manifold in such a manner that said coil spring is in contact with an upper part of said intake manifold.

Claim 13

An engine intake pipe arrangement comprising an intake pipe, said intake pipe being rigid but having some flexibility and having a rectangle-like cross section with three straight sides and one concave side, a support comprising an intake manifold connected to a downstream end of said intake pipe, and means for mounting and holding said intake pipe on said support including a resilient mounting member interposed between said intake pipe and said support for mounting said intake pipe in a floating manner on said support enabling the intake pipe to be movable relative to said support, and a resilient fastening member fastening said intake pipe to said support, said mounting member including a coil spring mounted on said intake pipe to span said concave side thereof and in a predetermined stretched state, said intake pipe being placed on said intake manifold in such a manner that said coil spring is in contact with an upper part of said intake manifold.

Claim 14

An engine intake pipe arrangement as set forth in claim 10 in which said mounting and holding means further have a pair of hooks in the form of projections provided to said intake manifold and a pair of hooks in the form of projections provided to said intake pipe, and in which said fastening member comprises a pair of coil springs which are hooked at the opposed ends thereof and in a predetermined stretched state to said intake pipe hook and said intake manifold hook, respectively.
