Abstract
A hydraulic gear-type machine has two meshing gears with axis-defining shafts received in respective journals having end faces turned axially toward the respective gears and formed with cutouts opening in opposite directions in line with input and output passages formed in a housing carrying the journals and enclosing the gears. The journals abut flatly at the cutouts along surfaces extending axially to immediately adjacent gears and chordally to cylindrical continuations of the outer surfaces of the journals. Each of the journals on each axial side of each gear is therefore formed with a recess opening toward the inlet passage and with a recess opening toward the outlet passage.
