Abstract

Freikolbenmotor in zylindrisch-gestreckter, zweiseitig-symmetrischer Bauweise mit einem stationären Basisteil (1) und zwei gleich gestalteten Motorhälften mit je einer Brennkammer (C) sowie mit einem innerhalb des Basisteils (1) gleitbeweglichen, eine Kolbenstange (8) aufweisenden Schwingkörper (6) und Verdichterkammern (B) zwischen der Kolbenstange (8) und dem Basisteil (1).Die Kolbenstange (8) ist mit ihren Enden an je einen Becherkolben (19) gekoppelt, welcher jeweils eine der Brennkammern (C) mitumschließt und gemeinsam mit dem jeweiligen Kolbenstangenende ein Ventil (9) bildet,wobei jeder Becherkolben (19) in einer zum Basisteil (1) gehörenden Laufhülse (3) und auf einem die Brennkammer (C) mitumschließenden zum Basisteil (1) gehörenden Zylinder (22) einer Zylinderplatte (5) gelagert ist, welcher gemeinsam mit der Laufhülse (3) jeweils eine Dämpferkammer (D) umschließt, in welche beim Betrieb des Motors Luft angesaugt wird, wobei sich an jedem Kolbenstangenende der Kolbenstange (8) zumindest eine Bohrung (8a) befindet, welche eine Einspritzdüse (8b) bildet, über welche jeweils im Bereich des unteren Totpunktes und bei geöffnetem Ventil (9) Kraftstoff, der sich mit im Bereich des Ventils (9) zugeführter Luft vermischt, in die jeweilige Brennkammer (C) gelangt.
