Abstract (en)
[origin: DE102004001840B3] Positive-displacement pump comprises a blade (22) for the mutual separation of two chambers in a housing chamber. The blade is driven by a drive shaft mounted in the pump housing. The blade has two partly overlapping blade parts (32, 34) that are aligned with each other and can be independently moved apart. The blade parts engage with each other on facing side surfaces (36) by a tongue and groove connection. The grooves (38) and the tongues (40) run orthogonally to the drive shaft. Preferred Features: The tongues and grooves form a labyrinth seal.
