Abstract
Official abstract text for this publication.
The invention relates to a low pressure pump/vacuum pump for gaseous media, comprising two interacting combs the teeth of which are configured as cycloidal components, the duplicate compressor stages being interconnected. A power unit of the pumps/compressors is driven and the power unit of the other pump/compressor, which is arranged coaxially, is entrained via a rotational connection.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rotary piston pump for gaseous media, comprising: an axially and radially supported power part, embodied as a spherical segment of a spur tooth; a blocking part of a same radial sealing diameter, also embodied as a spherical segment of a spur tooth and driven by the power part; work chambers between the power part and the blocking part, the power part and blocking part are guided radially sealingly in a pump housing; the pump, formed of the pow…
