Document Type and Number:
WIPO Patent Application WO/2014/189280
Kind Code:
A1
Abstract:
The present invention relates to a lubricator capable of efficiently supplying a lubricant to two portions requiring lubrication without a separate distribution device, the lubricator comprising a pump and two outlets. To this end, provided is a lubricator comprising: a pump body; a piston; first to fourth check valves; a lubricant storage unit; and a piston driving unit. The pump body comprises: a cylinder; an inlet flow path; a first outlet flow path; and a second outlet flow path, wherein one end of the cylinder is closed and the other end of the cylinder is opened, the inlet flow path is formed in one end side of the cylinder such that the inlet flow path is vertically connected with the cylinder, the first outlet flow path is formed to be connected with the cylinder while facing the inlet flow path, the second outlet flow path is formed to be connected with the cylinder while being spaced apart by a predetermined distance in the direction of the other end of the cylinder from the position where the inlet flow path and the first outlet flow path are formed. The piston comprises an internal flow path which connects an inlet hole formed in one end of the piston and a circumference groove formed to be spaced apart from the inlet hole by a predetermined distance in the direction of the other end of the piston. The piston is adapted to be inserted into the cylinder. The first to fourth check valves are respectively positioned in the inlet side of the inlet flow path, the outlet side of the first and second outlet flow paths, and the internal flow path of the piston. The lubricant storage unit in which the lubricant is stored is connected to a first check valve. The driving unit drives the piston such that the inlet hole reciprocates between one end of the cylinder and one position of the first and second outlet flow paths.
