ABSTRACT:
A device for extruding high viscosity fluids is described which has multiple modes of operation and provides a mechanism for relieving pressure being applied to fluid being extruded. The pressure release mechanism includes a first and second dog and a release arm that engages the second dog to result in the second dog disengaging the teeth of a drive rod attached to a piston for applying pressure to the fluid material to be extruded resulting in relief of the applied pressure by the drive rod and piston combination to stop the flow of the fluid from the nozzle of the device. The preferred device is a caulking gun.
