FIELD: engines and pumps.
SUBSTANCE: invention relates to gear pumps with infinitely-variable output flow rate. The gear pump with infinitely-variable output flow rate in which, at least, one first gear wheel (3) is installed on the first shaft (1), at least, one second gear wheel (4) is installed on the second shaft (2). Wheels (3, 4) are installed with a possibility of movement with reference to each other in the axial direction. The wheel (3) is sealed from one end with the first seal (7), and from the other end - with the second seal (9). Seals (7, 9) are placed on the shaft (1). The wheel (4) is sealed from one end with the first seal (10), and from the other end - with the second seal (8). Seals (10, 8) are placed on the shaft (2). A wheel (3) contains the first ring (5) with channels, or segments with channels, tightly and coaxially placed on the wheel (3). The wheel (4) contains the second ring (6) with channels, or segments with channels, tightly and coaxially placed on the wheel (4). The ring (5) or segments are designed with a possibility of movement with a wheel (4). The ring (6) or segments are designed with a possibility of movement with a wheel (3).
EFFECT: invention is aimed at ensuring of constant variation of output parameters from 0 to maximum rated values of flow rate and pressure.
