摘要： A gear machine includes two externally intermeshing gear wheels enclosed by a housing that has a high-pressure connection and a low-pressure connection situated opposite one another. On an inner circumferential face of the housing, a notional boundary line is assigned to both gear wheels. The line runs parallel to the line of contact between the gear tooth tips of the gear wheels and the inner circumferential face. The intersection edge is located between the two boundary lines and the minimum distance between the intersection edge and the boundary lines are at least one pitch interval of the gear wheels. The cross sectional shape of the low-pressure connection deviates from the circular shape such that its cross sectional area overlapping the gear wheels is greater than the cross sectional area of a notional, circular low-pressure connection overlapping the gear wheels at the same minimum distance from the boundary lines.
