OSTI ID:6976286
This patent describes an improvement in a pressure actuated apparatus for firing a perforating gun disposed in a tubing string within a borehole having an elongated housing and an arming means including a piston moveable in a fluid chamber and fixed to the housing by a shear member which is shearable in response to the fluid pressure within the tubing string, a striker fixed to the piston and spring biased to move in a direction for firing the perforating gun. The improvement comprising first means for protecting the shear member from any tensile force due to the spring bias.
