  • Patent number: 6024544
    Abstract: A coolant supply apparatus for a linear compressor which includes a stator mounted at one side of a flange for generating a magnetic field therearound and a horizontal operating unit which reciprocates horizontally. The horizontal operating unit includes a magnet disposed inside the stator and a piston, which is integral with the magnet and reciprocates horizontally within a cylinder. The coolant supply apparatus further includes a coolant oil pocket for guiding a predetermined amount of coolant oil to an outer circumferential surface of the cylinder in cooperation with a suction force of the piston and for cooling a heat generated in the cylinder. A plurality of coolant oil sucking/discharging holes are formed at the cylinder in order for the coolant oil filled in the coolant oil pocket to be introduced between the cylinder and the piston therethrough.
