Abstract
An automatic lubricant dispenser is detachably mounted on a bearing of a machine to continuously supply lubricant to the bearing. The dispenser includes a housing for storing the lubricant inside, a piston upwardly compressing the lubricant inside the housing, a spring installed at a bottom of the piston, for compressing and elastically supporting the piston, and a flow pipe installed vertically by extending through both the housing and the piston. The flow pipe is formed with an inflow hole on a top portion thereof and an inside hollow channel so that the lubricant compressed by the piston flows into the flow pipe and is then discharged into a bottom of the housing. An operator can voluntarily control the accurate flow amount of the fluent lubricant.
