time elapses between the time the triggering signal is received by the actuator 122 and the split ring 120 is released from the recess 114 when the split ring 120 is released from the recess 114 fluid pressure within the chamber 106 will urge the outer collar 102 axially upwardly so that the upper end 112 will compress the sealing element 32 the sealing element 32 will be deformed radially inwardly to seal against the tubing string 40 as depicted in fig8 to create a seal referring now to fig9 and 10 a further exemplary packer device 130 is depicted which utilizes hydraulic setting via the tubing string 40 the sealing element 32 is retained within the chamber 28 along with a setting piston 132 the setting piston 132 features an enlarged compression head portion 134 that abuts the sealing element 32 and a reduced diameter stem portion 136 that extends downwardly from the head portion 134 a ratchet mechanism 138 is located at its lower end of the stem portion 136 and operates in the manner of a body lock ring to ensure one way sequential movement of the setting piston 132 with respect to the surrounding casing coupler 18 a fluid chamber 140 is defined between the setting piston 132 and the casing string 17 within the enlarged chamber 28 fluid flow ports 142 are disposed through the setting piston 132 to permit fluid communication between the fluid chamber 140 and the interior flowbore 144 of the setting piston 132 fluid seals 146 are provided between the setting piston 132 and the casing coupler 18 to ensure fluid tightness of the fluid chamber.
