The present invention relates to a dual cylinder de-activation (CDA) device comprising: a main body; a swing arm part coupled to one side of the main body so as to come in contact with a cam by rotation thereof to be rotated for the main body; a latching part coupled to the other side of the main body so as to move between an unlocking position where the swing arm part is rotated for the main body, and a locking position where the latching part is engaged with the swing arm part to restrict the rotation thereof for the main body, wherein the latching unit is coupled to pivot parts, to which a working fluid can be supplied, so as to move between the locking position and the unlocking position; a plurality of stem contact members provided with a plurality of valves on one side of the main body, which is an area where the swing arm part is coupled, to be supported; and a plurality of pivot contact members provided with the pivot parts on the other side of the main body, which is an area where the latching part is coupled, to be contacted. Thus, it can be possible to provide a dual CDA device which has a structure that a plurality of valves can be coupled to or supported on one CDA device and a plurality of valves can be stably supported on one CDA device, and can improve the utilization of space including a cylinder. |
