Claims (5)

1. Шестеренчатый насос (110), содержащий: корпус (112), имеющий внутренние стенки (114), образующие входной канал (116), выходной канал (118) и камеру (120) с шестернями, расположенную между входным каналом и выходным каналом; первую и вторую нагнетающие шестерни (122, 123), установленные с возможностью вращения в камере с шестернями, причем первая и вторая нагнетательные шестерни имеют зубья, зацепленные между собой; и компрессионные зоны (126, 127), расположенные между каждой нагнетающей шестерней и внутренними стенками камеры с шестернями, отличающийся тем, что каждая компрессионная зона (126, 127) имеет переменную толщину вдоль продольного направления нагнетательных шестерен, причем эта непостоянная толщина уменьшается от места между аксиально противоположными торцами нагнетающих шестерен по направлению к каждому из торцов нагнетающих шестерен.1. A gear pump (110), comprising: a housing (112) having inner walls (114) forming an inlet channel (116), an outlet channel (118) and a gear chamber (120) located between the inlet channel and the outlet channel; the first and second pressure gears (122, 123) mounted rotatably in the gear chamber, the first and second pressure gears having teeth meshed to each other; and compression zones (126, 127) located between each pressure gear and the inner walls of the gear chamber, characterized in that each compression zone (126, 127) has a variable thickness along the longitudinal direction of the pressure gears, and this non-constant thickness decreases from the place between axially opposite ends of the pinion gears towards each of the ends of the pinion gears. 2. Насос по п. 1, в котором толщина компрессионных зон (126, 127) непрерывно уменьшается от места, расположенного по центру между аксиально противоположными торцами, по направлению к каждому из торцов нагнетающих шестерен. 2. The pump according to claim 1, in which the thickness of the compression zones (126, 127) is continuously reduced from the place located in the center between the axially opposite ends, towards each of the ends of the pressure gears. 3. Насос по п. 1, в котором толщина компрессионных зон (126, 127) непрерывно и плавно уменьшается от места, расположенного по центру между аксиально противоположными торцами, по направлению к каждому из торцов нагнетающих шестерен. 3. The pump according to claim 1, in which the thickness of the compression zones (126, 127) continuously and smoothly decreases from the place located in the center between the axially opposite ends, towards each of the ends of the pressure gears. 4. Насос по п. 3, в котором толщина каждой компрессионной зоны (126, 127) выполнена наибольшей в месте, расположенном рядом с впускным каналом, причем она непрерывно убывает по направлению к выходному каналу. 4. The pump according to claim 3, in which the thickness of each compression zone (126, 127) is made the greatest in the place located next to the inlet channel, and it continuously decreases towards the outlet channel. 5. Насос по п. 4, в котором толщина компрессионных зон (126, 127) плавно убывает от входного канала к выходному каналу. 5. The pump according to claim 4, in which the thickness of the compression zones (126, 127) gradually decreases from the input channel to the output channel.
