Description
eine Trenneinrichtung für das Trennen der Ansaugkammer vom externen Kühlkreislauf. Erfindungsgemäß ist es ferner vorgesehen, daß
die Trenneinrichtung nur für den Fall, daß die Taumelscheibe einen minimalen Neigungswinkel annimmt, die Ansaugkammer vom externen Kühlkreislauf trennt, während sich ein Umlaufkanal zur Verbindung der Auslaßkammer über Kurbelkammer mit der Ansaugkammer öffnet, wobei
eine Ablaßeinrichtung vorgesehen ist, die bei in Betriebnahme der Trenneinrichtung eine solche Verbindung zwischen der Ansaugkammer und dem externen Kühlkreislauf herstellt, daß ein schneller Abbau des in der Kurbelkammer herrschenden Drucks in die Ansaugkammer verhinderbar ist, um somit ein schnelles Anwachsen des Neigungswinkels zu unterdrücken.
