ABSTRACT:
An apparatus for supplying a viscous material to locations, comprises:a pump;a supply line in fluid communication with the pump;a first main line having a first compression chamber;a second main line having a second compression chamber;a 3/2-way valve for placing the supply line in fluid communication with either the first main line or the second main line;a two-line distributor having a control piston; anda controller for controlling the pump and the 3/2-way valve, such that(i) at a start of a cycle the pump operates to deliver the viscous material, with the 3/2-way valve positioned so as to place the supply line in fluid communication with the first main line, through the supply line and into the first main line, and then(ii) through pressure build-up in the first main line, resulting from the viscous material flowing through the supply line into the first main line, the two-line distributor operates to transport the viscous material, by movement of the control piston, into the second compression chamber and to a plurality of the locations.
