<p>The present invention relates to a non-fueling type natural gas compressor, which completely blocks the flow of oil between a cylinder and a crank while not requiring the separate supply of oil to the cylinder by including a separate distance piece inside the natural gas compressor. According to the present invention, the non-fueling type natural gas compressor comprises: a crank assembly (100) provided with a link performing a rotary motion; a cylinder assembly (200) arranged to be spaced apart from the crank assembly (100), and provided with a cylinder (210); a distance piece (300) arranged between the crank assembly (100) and the cylinder assembly (200), and configured to block oil included in the crank assembly (100) from flowing into the cylinder assembly (200); and a piston rod (400) configured to pass through the distance piece (300), and arranged across the crank assembly (100) and the cylinder assembly (200). According to the present invention as described above, the flow of oil flowing from the crank assembly to the cylinder assembly can be completely blocked.</p> |
