Patent ID: 7367428

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