In a lubricating device for a plurality of lubricating stations, in
particular for supplying lubricant to knitting machines, a pump device is
provided that serves at the same time as a distributor device. To that
end, the pump device has a piston which is provided with a control
groove. The corresponding pump cylinder has an inlet and a plurality of
outlets distributed over the cylinder wall. Depending on which of the
outlets the control groove of the piston is made to coincide with, a
corresponding lubricating station is selected. The pump device is thus a
distributor device as well.
