Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
169 words
A manifold reactor comprising: an inner core; an outer core which encloses said inner core therein; said outer core having an inlet tube mounted therein; said inner core having a tubular portion for introducing exhaust gases therein; said tubular portion having a flanged inlet end; said inlet tube being telescopically received by said tubular portion; an annular elastic seal element made of a stack of a plurality of annular heat resistant elastic metal sheets and having an L-shaped cross section defined by a flange portion and a tubular portion; said flange portion of said annular seal element being connected to said flanged inlet end of said inner core tubular portion in a manner such that a relative axial movement between said annular seal element and said inner core tubular portion is prevented while said tubular portion of said annular seal element is received between said inner core tubular portion and said inlet tube; and said annular seal element being slidably engaged on a peripheral surface of said inlet tube.
Claim 2
Dependent Claim
169 words
A manifold reactor comprising: an inner core; an outer core which encloses said inner core therein; said outer core having an inlet tube mounted therein; said inner core having a tubular portion for introducing exhaust gases therein; said tubular portion having a flanged inlet end; said inlet tube being telescopically received by said tubular portion; an annular elastic seal element made of a stack of a plurality of annular heat resistant elastic metal sheets and having an L-shaped cross section defined by a flange portion and a tubular portion; said flange portion of said annular seal element being connected to said flanged inlet end of said inner core tubular portion in a manner such that a relative axial movement between said annular seal element and said inner core tubular portion is prevented while said tubular portion of said annular seal element is received between said inner core tubular portion and said inlet tube; and said annular seal element being slidably engaged on a peripheral surface of said inlet tube.
Claim 3
Dependent Claim
47 words
The manifold reactor of claim 1, wherein an annular element having an L-shaped cross section is attached to said flanged inlet end of said inner core tubular portion so as to define an annular chanel in which said flange portion of said annular seal element is received.
