Abstract

An engine exhaust dispersing device includes a tubular member having a first portion formed as a generally cylindrical wall and adapted to be mounted in fluid communication with an exhaust outlet and a second portion formed as a longitudinally-sectioned cylindrical wall defining a longitudinally extending opening, and, a wedge surface formed on said second portion and protruding into the longitudinally extending opening, the wedge surface having an apex adjacent or in the first portion and a base at an end of the second portion, the base having a width substantially equal to a width of the second portion.

Claims (12)

1. A dispersing device for a vehicle exhaust outlet, comprising:

a tubular member having a first portion formed as a generally cylindrical wall and adapted to be mounted in fluid communication with an exhaust outlet and a second portion formed as a longitudinally-sectioned cylindrical wall defining a longitudinally extending opening, and

a wedge element disposed in said second portion and protruding into the longitudinally extending opening, the wedge element having an apex adjacent the first portion and a base at an end of the second portion, the base having a width substantially equal to a width of the second portion,

wherein the wedge element includes two substantially triangular planar surfaces joined at a ridge, the ridge extending from the apex to the base and diverging from the second portion obliquely relative to a long axis of the tubular member.

2. The device as claimed in claim 1 , further comprising vents formed in the first portion.

3. The device as claimed in claim 1 , wherein the first portion includes a collar configured to receive a free end of an exhaust pipe.

4. A dispersing device for a vehicle exhaust outlet, comprising:

a tubular member having a first portion formed as a generally cylindrical wall and adapted to be mounted in fluid communication with an exhaust outlet and a second portion formed as a longitudinally-sectioned cylindrical wall defining a longitudinally extending opening, and

a wedge element disposed in said second portion and protruding into the longitudinally extending opening, the wedge element having an apex adjacent the first portion and a base at an end of the second portion, the base having a width substantially equal to a width of the second portion,

wherein the wedge element includes a central planar part extending from the apex to the base and diverging from the second portion obliquely relative to a long axis of the tubular member and two substantially triangular side parts.

5. The device as claimed in claim 4 , further comprising vents formed in the first portion.

6. The device as claimed in claim 4 , wherein the first portion includes a collar configured to receive a free end of an exhaust pipe.
