Title: An over-head tank having pressure accumulation
Inventor: YOO HUI SEUNG
IPC: F16N13/00
Filed: 2001-12-12
Abstract: PURPOSE: An overhead tank having a pressure accumulating function is provided to prevent the damage of a bearing unit by supplying lubricating oil to the bearing unit when a blower stops. CONSTITUTION: In an auxiliary overhead tank installed at a blower and having a casing(5), a piston(35) is installed in the casing, and is elastically supported by a spring(27). A spool is installed at the center of the piston, and has lower specific gravity than lubricating oil. A check valve(60) is formed at the spool, and closes the passage connected from the lower part of the piston to the upper part. The piston moves up and down in the casing. The pressure of a pump compresses the spring. The lubricating oil is supplied to a bearing unit by the restoring force of the spring when the pump stops.
