A boil off gas (BOG) compressor is disclosed. According to one aspect of the present invention, the BOG compressor comprises: a cylinder having an inner space where the BOG is compressed; a piston linearly reciprocating inside the inner space of the cylinder to compress the BOG; an intake valve opening and closing an intake hole of the cylinder; an exhaust valve opening and closing an exhaust hole of the cylinder; and a charging unit coupled to a side wall of the cylinder guiding a linear reciprocating motion of the piston and providing electrostatic attraction to a lubricant which is a polar material. The purpose of the present invention is to provide a BOG compressor which minimizes a leakage of the lubricant. |
