Title: Fluid transferring device
Inventor: TAMURA YUKIO
IPC: B29C48/53
Filed: 1986-12-05
Abstract: PURPOSE:To prevent the leakage of liquid fluid at the screw base portion of a second stage cylinder by a method in which at the range of the pressurizing screw from the screw base portion of a second stage cylinder to a main screw, the raw material fed separately is gradually pressurized, while changing said raw material into liquid fluid or leaving it as liquid fluid.
