Claims (5)

Patentansprüche:
1. Membraneinspritzpumpe für Brennkraftmaschinen, insbesondere für kleinere Motoren, dadurch gekennzeichnet, daß außer der pumpend wirkenden Membran eine zweite Membran angeordnet ist, deren Ausweichbewegung beim Druckhub der Pumpe durch einen verstellbaren Anschlag gestoppt wird.
2. Membraneinspritzpumpe nach Anspruch 1, dadurch gekennzeichnet, daß die Ausweichmembran von gleicher Größe und Form ist wie die Pumpenmembran.
3. Membraneinspritzpumpe nach Anspruch 1, dadurch gekennzeichnet, daß die Membranen jeweils aus mehreren aufeinanderliegenden dünnen Membranen zusammengesetzt sind.
4. Membraneinspritzpumpe nach Anspruch 1, dadurch gekennzeichnet, daß die Einspannstelle der Membranen wulstförmig ausgebildet ist.
5. Membraneinspritzpumpe nach Anspruch i, dadurch gekennzeichnet, daß der Druckhub der Pumpenmembran durch den Gasdruck des Verbrennungskraftmaschinenzylinders bewirkt wird, zweckmäßig über eine weitere vom Gasdruck beaufschlagte Membran, die die Pumpenmembran durch ein zwischengeschaltetes Mittel (Druckkolben 3) bewegt.
