Abstract

Bei der hydraulischen Verdrängermaschine erfolgt die stirnseitige Abdichtung rotierender Verdränger über eine Druckplatte (42). Sie wird über ein Regelventil (62) mit einem Druck beaufschlagt, über den die Größe des Dichtspaltes beeinflußbar ist. Erfindungsgemäß hat das Regelventil (62) einen eine Meßblende ausbildenden Hohlkolben, über den ein Rücklaufanschluß, ein zum Verbraucher führender Anschluß und ein hydraulisch mit der Druckplatte (42) verbundener Steueranschluß ansteuerbar sind. Die Verdrängermaschine wird vorzugsweise als Zahnradmaschine ausgebildet. Das Regelventil zeichnet sich durch einen äußerst kompakten Aufbau aus, so daß das Gehäuse (1) der Verdrängermaschine sehr einfach ausgebildet werden kann.
