Abstract (en)
[origin: EP2711552A2] The gear machine has housing having high and low pressure terminals (33). A notional boundary line (80) assigned to externally intermeshing gear wheels (50) on inner circumferential face of housing runs parallel to line (83) of contact between gear tooth tips of wheels and inner circumferential face. The cross sectional shape of low-pressure terminal deviates from circular shape such that cross sectional area overlapping wheels is greater than that of notional, circular low-pressure terminal overlapping wheels at minimum distance from boundary lines.
