摘要
The arrangement is intended for equalising pressure in a gear pump with externally meshing gears. A wear plate (28) is positioned in the pump chamber (5) between the end faces of the gear wheels and the housing end cover. - Between the plate and the end cover there is a branch (76) of a pressure equalisation groove (75), the branch extending from a recess in the pump suction area and concentrically in the direction of rotation of the adjacent gear. The groove (75) is arranged in the face of the end cover and its branches (76) each have an end portion (77) which extends radially relative to the end face of the adjacent gear.
