  • Publication number: 20140341690
    Abstract: The present disclosure relates to a parallel linkage-type working apparatus for construction equipment in which a parallel lever and a parallel link operate to prevent a working tool from bending inward so that, even if the working tool is raised, a tilting phenomenon in which the working tool is inclined inward may be prevented, and an amount of change in posture of the working tool at each height may be reduced. Also, the parallel linkage-type working apparatus is capable of increasing excavation ability or power with a posture on the ground surface by supplying a larger amount of hydraulic fluid at one time when working hydraulic pressure is supplied to each cylinder head, in comparison with a case in which working hydraulic pressure is supplied to a cylinder rod.

  • Publication number: 20130309361
    Abstract: A refrigerator having a carbonated water production module integrally provided with a carbon dioxide gas cylinder having carbon dioxide gas stored therein and a carbonated water tank to mix purified water with the carbon dioxide gas to produce carbonated water. The carbonated water production module is mounted to the rear surface of the door, and thus it may be cooled by cool air in the refrigeration compartment and be easy to access, and thereby repair and replacement thereof is facilitated. The dispenser includes a carbonated water discharge channel into which carbonated water from the carbonated water tank is discharged, and a purified water discharge channel into which purified water from the water tank is discharged. Since the purified water discharge channel does not pass through the carbonated water tank, a user is allowed to selectively dispense purified water or carbonated water anytime.
