Abstract
An arming apparatus for arming a downhole tool in a wellbore casing comprising an arming member and a holding device. The arming member is disposed within an outer housing of the downhole tool and the holding device is mechanically coupled to the arming member. When a ball deployed into the wellbore casing passes through the downhole tool in a downhole direction and moves back in an uphole direction due to reverse flow, the ball engages on the holding device and functions the arming member such that a pressure actuating device in the downhole tool is armed.
