Abstract (en)
[origin: WO2013072206A2] The invention relates to an internal gear pump (6), in particular for a motor vehicle, for conveying a fluid, comprising an internal gear (22) having an internal toothed ring (23), an external gear (24) having an external toothed ring (25), wherein the teeth (21) of the internal and external gears (22, 24) mutually engage, a work space (47) formed between the internal gear (22) and the external gear (24), which is divided into an inflow work space (30) and an outflow work space (31), an inflow channel (28) opening into the inflow work space (30) for introducing the fluid to be conveyed into the inflow work space (30), and an outflow channel (29) opening into the outflow work space (31) for discharging the fluid to be conveyed from the outflow work space (31), wherein the inflow work space (30) and the outflow work space (31) are separated from one another at a head location (48) and at a cog point (49) between the internal and the external gears (22, 24), wherein the inflow channel (28) in addition opens in part in an angular area (50) of the outflow work space (31).
