Radial piston pump and drive motor unit - has shaft with slide bearing, which may use sintered metal furthest from eccentric cam which may have counterweight revolving with shaft
The unit consists of a drive motor, with a stator and an armature (9), and a pump with at least one radial piston (33) driven by an eccentric cam (28). The cam and the armature are mounted on a common shaft (11). The shaft has a first bearing between the armature and the cam, and a second bearing near to the cam. A third bearing (14) is arranged near to the armature, and operates by sliding, and may be made from sintered metal. The eccentric cam may also be associated with a counter weight (46), which revolves with the shaft.
