ABSTRACT:
Pressurized fluid for the squeeze cylinders of an "extrusion" baler is supplied by a single-acting pump cylinder that is connected between the plunger head and its push rod in such a way as to deliver a slug of pressurized fluid into the circuit on each compression stroke of the plunger, the pump drawing in a fresh slug from a reservoir during each retraction stroke of the plunger. The push rod is connected to the plunger in a cranked relationship so that the radial distance between the end of the push rod and the fulcrum point of the crank comprises one lever arm, such lever arm being many times smaller than the lever arm between the fulcrum point and the point of connection of the crank of the pump cylinder.
