Abstract
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.
