CDA DEVICE

摘要

A CDA device includes: an outer body that moves up/down in contact with a cam and has an oil input hole at one side and latching pin chambers; an upper seat disposed inside the outer body; an inner body disposed slidably inside the outer body, has a latching pin hole, and is combined with a valve; a lost motion spring that elastically supports the outer body in a lost motion between the inner body and the outer body; latching pins that are slidably disposed in the latching pin chambers and inserted in the latching pin holes; and latching pin springs that push the latching pins into the latching pin hole, in which hydraulic pressure selectively transmitted from the oil input hole pushes the latching pins and the latching pins are separated from the latching pin holes.

1. A CDA device comprising:
an outer body driven by a cam to move up and down, the outer body including an oil input hole at one side and latching pin chambers; an upper seat disposed inside the outer body; an inner body slidably disposed inside the outer body, including a latching pin hole, the inner body operably driving a valve; a lost motion spring that elastically supports the outer body for lost motion between the inner body and the outer body; latching pins slidably disposed in the latching pin chambers and selectively inserted in the latching pin holes; and latching pin springs that push the latching pins into the latching pin hole; wherein hydraulic pressure selectively transmitted through the oil input hole pushes the latching pins and the latching pins are separated from the latching pin holes.
