Abstract

In these pumps, each cover 1 of the casing incorporates two housings 2 and 3 for the shafts of the gearing, these housings being connected together by means of a channel 7. The improvements consist in giving one 3 of these housings, in its opening, a perimeter recess 5 which does not cover its entire contour, specifically which does not cover a sector 6 which is offset with respect to the channel 7, this sector 6 acting as a stop which limits axial displacement for the bushing installed on the corresponding shaft, the recess 5 preventing the aforesaid bushing closing off the passage of lubricant to the inside of the housing 3 and from the latter to the housing 2 via the channel 7.
