Abstract

1295603 Distributing lubricant DE LIMON FLUHME & CO 29 April 1971 [15 May 1970] 12110/71 Heading F2A A lubricant distributing system has at least two distributer units 10, 13, each unit having at least two double-acting pistons 11, 12, 13 reciprocable within a cylinder, the cylinder having two working chambers 14, 15 and a distributing chamber 16. Each piston carries a slide valve 17 for allowing communication of lubricant pipes opening into the distributer chamber. Each distributer unit has an intake pipe 24 from which supply pipes lead to the distributer chambers. A pipe 35 leads from one of the distributing chambers to a distributing chamber in the other unit and constitutes the only feed of lubricant to that chamber. The chambers are connected in such a way that the pistons force lubricant into each delivery line 18-23 in turn. One of the pistons may be connected to a control device which stops the pump after each distributer unit has completed its cycle, and a timing device may be provided for restarting the pump after a predetermined interval. Different quantities of lubricant may be provided to different lubricating points by having the cylinders of varying sizes. The ratio of the volumes of the cylinders is in whole number ratio, operation being completed by the required number of strokes of the other pistons.
