Abstract
Abstract To initiate liquid-fuel combustion or monofuel decomposition, and particularly to operate an impact cylinder by a fuel without requiring a spark or hot point, part of the fuel for each stroke is injected into a firing breech containing a gas and sealingly cooperating with a firing pin which when released by a trigger fires this fuel by compression of the gas in the breech to reach firing pressure and temperature, the resultant pressure increase being utilized for opening communication from the breech to a main reaction chamber into which the remainder of the fuel has been injected and also for recocking the firing pin.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
32 words
A device as claimed in claim 1, wherein the charging means include a single-stoke priming pump arranged to supply fuel to both the breech and the reaction chamber in individually metered quantities.
Claim 2
Dependent Claim
34 words
A device as claimed in claim 2, wherein the priming pump includes means for adjusting the quantity of fuel supplied to the reaction chamber without affecting the quantity of fuel supplied to the breech.
Claim 3
Dependent Claim
19 words
A device as claimed in claim 1, wherein said body includes a monofuel reservoir associated with said charging means.
Claim 4
Dependent Claim
62 words
A device as claimed in claim 1, for use in connection with a gas turbine, wherein the charging means include means operable, after the release of the detent means, to direct a continuous supply of fuel to the reaction chamber, the device including a pressurizing valve rendering said conduction means ineffective until the pressure in the reaction chamber reaches a predetermined valve.
Claim 5
Dependent Claim
128 words
A device as claimed in claim 1, wherein the breech bore is a socket bore closed at its end remote from the reaction chamber, and which includes means in said body guiding said firing pin along a path that includes a first position in which said sealing portion is wholly outside said cylindrical bore portion to permit free communication between said reaction chamber and said breech bore, and a second position in which said sealing portion of the firing pin is in engagement with said cylindrical bore portion so that rapid movement of the firing pin from said first position to said second position will trap a volume Of fluid in said breech bore and compress it sufficiently to ensure firing of such mixture in said breech bore.
