Check va lve
The delivery pump consits of a piston pump, an electric magnet and an oil reservoir.
Suction phase:
The pistons are reset by spring force with the lubricant being sucked in from the reservoir by
virtue of the vacuum generated.
Compression phase:
Upon electric magnet actuation, the pistons start to deliver to lubricant through the nozzles to
the lubricating points.

Operation GOI-A
Suction phase
Pressure phase
Suction conn ector (reservo ir)
Suction conn ector (reservo ir)
The aggregate consits of a one- or two-digit piston pump, an electric magnet, a control unit
and an oil reservoir.
Suction phase:
The piston is put back by means of spring tension. Due to the negative pressure generated,
the medium will be sucked out of the reservoir.
Pressure phase:
The magnet actuated piston delivers the medium into the airflow. By virtue of the airflow
preset via the throttle valves the resulting oil film will be continuously transported to the
friction and lubrication points.
