Abstract

Ein Kraftstoffpumpsystem für einen Verbrennungsmotor (10) mit einem an eine Stromquelle (14) anschließbaren Solenoid (22), das eine Spule (28) aufweist, um während des Anlaßvorgangs die Kraftstoffzufuhr zu aktivieren, ist mit einem Thermistor (60) versehen, der sich im stromdurchflossenen Zustand erwärmt und mit der Spule (28) verdrahtet ist, wobei mit dem Thermistor (60) und mit der Spule (28) ein Schalter verbunden ist, der den Stromdurchfluß durch den Thermistor (60) unterbrechen kann.

Figure 00000001
A fuel pump system for an internal combustion engine (10) with a solenoid (22) which can be connected to a power source (14) and which has a coil (28) to activate the fuel supply during the starting process is provided with a thermistor (60) is heated in the current-carrying state and is wired to the coil (28), a switch being connected to the thermistor (60) and to the coil (28), which can interrupt the current flow through the thermistor (60).
