Abstract

Eine Pumpe mit axial beweglichem Pumpelement, insbe­ sondere Membranpumpe, weist eine hin- und hergehende Betätigungsstange (22) und einen axial relativ hierzu verschi­ ebbaren Verdrängerkolben (24) auf. Ein Ventil (35), das den Flüssigkeitsausgleich im Hubraum (26) sowohl bei Flüssigke­ itsmangel als auch bei Flüssigkeitsüberschuß dient, wird zwischen den einander zugewandten Stirnseiten von Betätig­ ungsstange und Verdrängerkolben (24) gebildet. Der Verdrä­ ngerkolben ist mittels eines Dichtrings (25) in der Zylinderb­ ohrung (15) abgedichtet. Auf diese Weise werden Leckverluste beim Druckhub vermieden und ein Mittenver­ satz ausgeglichen.
