Abstract
Abstract A combustion chamber for pulsating combustion of a fuel air mixture has at one end an inlet for fuel air mixture and at the opposite end an outlet for gases. The cross section of the chamber at right angles to a line between the inlet and the outlet has a configuration which deviates from the circle due to the fact that the chamber has a number of side chambers. A transverse shield or plate partitions the combustion chamber into a first and a second partition chamber so that a fuel air mixture flowing towards the plate will be guided out into the side chambers and become ignited and will further pass through said side chambers into the second partition chamber.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A combustion chamber particularly for pulsating combustion of fuel air mixture having at one end an inlet for fuel mixture and at an opposite end an outlet for exhaust gases, wherein the cross section of the chamber between the inlet and the outlet has a configuration which deviates from the cross section of the inlet, the chamber having a number of side chambers, wherein a transverse shield partitions the combustion chamber into first and second compartments so that a fuel mixture flowing through the inlet into the first compartment will be caused to flow around the shield through its side chambers into the second compartment and thereupon to the outlet.
Claim 2
Dependent Claim
110 words
A combustion chamber particularly for pulsating combustion of fuel air mixture having at one end an inlet for fuel mixture and at an opposite end an outlet for exhaust gases, wherein the cross section of the chamber between the inlet and the outlet has a configuration which deviates from the cross section of the inlet, the chamber having a number of side chambers, wherein a transverse shield partitions the combustion chamber into first and second compartments so that a fuel mixture flowing through the inlet into the first compartment will be caused to flow around the shield through its side chambers into the second compartment and thereupon to the outlet.
Claim 3
Dependent Claim
37 words
