Samsung patents compressor design that guides oil inside a moving roller

This patent describes a specific type of compressor used to move refrigerant, likely for cooling systems. It features a rotating roller with a built-in channel that directs lubricating oil to a sliding part called a vane, which helps seal the compression area.

Why it mattersThis is a routine mechanical improvement aimed at better lubrication and efficiency in standard cooling hardware.

In the filing’s own words

A compressor includes a housing, a cylinder, a roller, and a vane. The cylinder is inside the housing and has a cylinder chamber formed therein. The roller is configured to be rotatable in the cylinder chamber, and has a vane groove on an outer surface and an oil guide that extends between the vane groove and the inner surface of the roller. The oil guide guides oil within the vane groove. The vane is configured to be inserted and moved in the vane groove. The vane and the roller together partition the cylinder chamber into an inlet chamber into which a refrigerant is introduced and a compression chamber in which the refrigerant is compressed.

What exactly they claim (claim 1)

1. A compressor comprising: a housing; a cylinder inside the housing and including a cylinder chamber formed therein; a roller configured to be rotatable in the cylinder chamber, the roller including a vane groove formed on an outer surface of the roller and an oil guide extending between the vane groove and an inner surface of the roller to guide oil within the vane groove; and a vane including: a first end secured by a fixing portion of the cylinder, and a second end opposite to the first end, the second end extending into the vane groove and configured to, reciprocate inside the vane groove along a longitudinal axis of the vane during rotation of the roller, wherein the vane and the roller together are configured to partition the cylinder chamber into an inlet chamber into which a refrigerant is introduced and a compression chamber in which the refrigerant is compressed.
