Abstract
Abstract In an internal combustion engine of the fuel-injection type fed with fuel by injection pumps, each pump comprising a piston operated by an actuating mechanism releasably connected thereto and with tripping means adapted to slow down and to stop the engine in case of overspeed, at least one servo-motor operated by said tripping means for acting upon said fuel-injection pumps, an emergency stopping arrangement wherein each one of said pumps is provided with an individual servo-motor acting directly upon the piston of said pump to disconnect said piston from its actuating mechanism.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
In an internal combustion engine of the fuel-injection type fed with fuel by injection pumps, each of which comprises a piston operated by an actuating mechanism releasably connected thereto, an emergency stopping arrangement comprising tripping means adapted to supply servo-motors with pressure fluid in case of overspeed of the engine, each of said serve-motors being associated with one of said pumps and comprising a piston-type actuator mounted on the associated injection pump, and a lever connected, on the one hand, to the piston of said pump and, on the other hand, to the piston of said actuator and pivotally mounted between its two ends on a stationary fulcrum point.
Claim 2
Dependent Claim
109 words
In an internal combustion engine of the fuel-injection type fed with fuel by injection pumps, each of which comprises a piston operated by an actuating mechanism releasably connected thereto, an emergency stopping arrangement comprising tripping means adapted to supply servo-motors with pressure fluid in case of overspeed of the engine, each of said serve-motors being associated with one of said pumps and comprising a piston-type actuator mounted on the associated injection pump, and a lever connected, on the one hand, to the piston of said pump and, on the other hand, to the piston of said actuator and pivotally mounted between its two ends on a stationary fulcrum point.
Claim 3
Dependent Claim
47 words
An arrangement according to claim 1, wherein each pump is formed with a lateral orifice giving access at least to the operative connection between its piston and associated actuating mechanism and each one of said actuators is mounted on said lateral orifice for releasably engaging said connection.
Claim 4
Dependent Claim
20 words
An arrangement according to claim 1, wherein each one of said actuators comprises a manual control lever for operating same.
