Abstract
A lubricant supply apparatus for a reciprocating compressor is provided having a lubricant cylinder fixed to a compressing unit having a lubricant suction passage and oscillating with the compressing unit. A lubricant piston is slidably inserted into the lubricant cylinder for sucking and discharging lubricant by generating a pressure change inside the lubricant cylinder in coordinated oscillation with the compressing unit. A lubricant valve fixed to the compressing unit and having a lubricant suction valve opening in a suction process of the lubricant piston and a lubricant discharge valve opening in a discharge process of the lubricant piston are also provided. A valve cover covers the lubricant valve and is fixed to the compressing unit and includes a discharge port opening and shutting by the lubricant suction valve.
