Abstract: The invention relates to a device for supplying a gaseous fuel to an engine that comprises a gas accumulator for receiving highly pressurized gaseous fuel, a gas buffer for receiving medium pressurized gaseous fuel, a gas supply device for delivering a gaseous fuel into an engine combustion space, a first gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a first valve, a second gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a second valve, and a third gas line that connects the gas buffer to the gas supply device. The device is further characterized in that a compressor is arranged in the second gas line to increase a pressure of a gaseous fuel flowing from the gas accumulator to the gas buffer.

Abstract: One or more techniques and/or systems are disclosed for interrupting fluid flow when experiencing fuel leaking conditions, such as an out of specification connection between the fuel source and a device utilizing the fluid. A distal end of a valve body has interfaces with at least a portion of a connection to a fluid supply; and a proximal end interfaces with at least a portion of a fuel intake. An internal passage runs between the proximal end and distal ends of. A displacement member in the internal passage comprises a distal portion that extends out of the valve to engage a valve to the fuel supply. A retention cap selectably engaged with the valve body can comprise a material that deforms under force at a predetermined temperature, resulting in a release of the displacement member under a biasing force form a biasing component between the cap and displacement member.

Abstract: An object of the present invention is to prevent generation of wear at a rod collision portion in an electromagnetic intake valve of a high-pressure fuel supply pump by reducing inclinations of the intake valve and a rod.
A structure of the electromagnetic intake valve of the high-pressure fuel supply pump is configured as follows. A seat portion of an intake valve and a guide portion of a rod are configured as an integral part, and further, a rod guide is made to have a sufficiently long length so that it is possible to perform guide at one portion. Further, the intake valve seat portion and a surface where the rod collides with the intake valve are formed on the same plane.

Abstract: A high pressure fuel pump includes an inlet metering valve arranged to control a quantity of fuel delivered to the pumping chamber during retracting motion of the pumping plunger. The inlet metering valve includes a metering valve member movable between a closed position and an open position, movement of the metering valve member from the closed position to the open position defining a variable flow area that increases as the metering valve member moves from the closed position toward the open position. An actuator piston in an actuator bore is exposed to pressure in the common rail. The actuator piston is biased toward a first position corresponding to low pressure in the common rail and movable toward a second position corresponding to maximum pressure in the common rail. The actuator piston includes a valve stop that determines a metering position of the metering valve member.
