Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
A fuel compensating device for a supercharged type diesel engine, comprising three stepped chambers forming a case, a large pressure receiving member and a small pressure receiving member reciprocable in the chambers by supercharging air pressure of the engine and spring forces, a connecting member connecting the pressure receiving members coaxially and provided with springs therebetween and a lever serving as a stopper in the fuel increasing direction for a fuel control rack in a fuel injection pump and being connected with the connecting member so that in low supercharging pressure the small pressure receiving member and the connecting member are movable by movement of the large pressure receiving member and in high supercharging pressure the connecting member alone is movable by the small pressure receiving member.
Claim 2
Dependent Claim
