Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
79 words
An exhaust gas purifier for diesel particulates which is connected to an exhaust pipe of a diesel engine for filtering off the particulates contained in exhaust gas and incinerating the particulates filtered off and accumulated, by means of an oil burner, characterized by comprising two parallel filter elements which are each made of ceramics and connected to said exhaust pipe of said diesel engine and said oil burner which is provided with a combustion chamber through a four-way valve.
Claim 2
Dependent Claim
79 words
An exhaust gas purifier for diesel particulates which is connected to an exhaust pipe of a diesel engine for filtering off the particulates contained in exhaust gas and incinerating the particulates filtered off and accumulated, by means of an oil burner, characterized by comprising two parallel filter elements which are each made of ceramics and connected to said exhaust pipe of said diesel engine and said oil burner which is provided with a combustion chamber through a four-way valve.
Claim 3
Dependent Claim
88 words
An exhaust gas purifier for diesel particulates according to Claim 1, wherein said four-way valve comprises a cylinder and an elliptical vane which is fixed to a shaft concentric with said cylinder and is adapted to be in contact with the inner surface thereof, and further has two gas inlets which open at positions on the exterior of the sliding surface for said elliptical vane and between which said elliptical vane is provided and two gas outlets which open at positions in said sliding surface in said cylinder.
Claim 4
Dependent Claim
51 words
An exhaust gas purifier for diesel particulates according to Claim 1, wherein said four-way valve comprises said cylinder and said elliptical vane and slots are provided in the periphery of said elliptical vane which slides in contact with the inner surface of said cylinder, sealing rings being placed in said slots.
Claim 5
Dependent Claim
42 words
An exhaust gas purifier for diesel particulates according to Claim 1, wherein a conjunction pipe from said four-way valve is connected to each of said filter elements in such a manner that its axis deviates from the axis of said filter element.
Claim 6
Dependent Claim
25 words
An exhaust gas purifier for diesel particulates according to Claim 1, wherein said combustion chamber comprises two sleeves between which a thermal insulator is charged.
Claim 7
Dependent Claim
36 words
An exhaust gas purifier for diesel particulates according to Claim 5, wherein air is passed between said two sleeves of said combustion chamber so as to cool said combustion chamber and then allowed to flow therein.
Claim 8
Dependent Claim
44 words
An exhaust gas purifier for diesel particulates according to Claim 1, wherein each of said filter elements made of ceramics is made of fiber ceramic obtained by sintering a composite material of heat-resistant fiber of aluminosilicate and clay and has a corrugated honeycomb form.
