Abstract

Axialkolbenverdichter mit variabler Förderleistung, insbesondere für den Kältemittelkreislauf einer Fahrzeug-Klimaanlage, mit Verbindungskanälen zwischen Triebwerkskammer und Ansaug- und/oder Auslasskammer, in denen Ventile, insbesondere Magnetventile, angeordnet sind, mittels denen der in der Triebwerkskammer herrschende Kältemitteldruck steuerbar ist, wobei zu diesem Zweck den Ventilen ein Regler zugeordnet ist. Diesem Regler wird die Änderung des Schadraums wenigstens einer Kolben-Zylinder-Einheit als Regelgröße hinzugeführt. Vorzugsweise ist die Regelgröße mittels eines zweiteiligen Ist-Wert-Aufnehmers erfassbar, der entweder kapazitiv arbeitet oder insbesondere als Hallgenerator mit zwei galvanisch voneinander getrennten Funktionselementen ausgebildet ist. Eines dieser Funktionselemente ist in Form eines an einem Kolben (50) befestigten Permanent-Magneten (B, C oder D) ausgebildet.
