Rotary piston pump e.g. for conveying liquid or gaseous media, has housing having two arranged inlet channels and two arranged discharge opening channels

摘要

The rotary pump has a housing having two arranged inlet channels and two arranged discharge opening channels. Two triangle turning pistons having the same rotating speed and controlled by a synchronization transmission, synchronously rotate in the same direction. The internal radii of the housing (16) and the radii of the turning piston (18) are in the ratio of 1: square root of 3.
