Compressed gas cartridge powered pepper spray gun

摘要

A pepper spray gun assembly having a trigger valve for dispensing a non-lethal spray, such as a pepper spray. The assembly includes a storage cylinder for receiving a non-lethal spray charge and a smaller pre-charged charging cylinder for engaging the storage cylinder. The charging cylinder is fluidly coupled to the storage cylinder so as to provide a regulated gas in the head space of the storage cylinder. When the trigger of the trigger valve is operated, the regulated gas will force the charge to be expelled through the nozzle of the trigger valve assembly.

主权项

1. A spray gun comprising:
a storage cylinder adapted to receive and contain a liquid pepper spray composition under pressure, the storage cylinder having a dip tube extending thereinto; a firing unit adapted to expel a spray charge under pressure, the firing unit having a nozzle, a charge delivery tube and a trigger; a pressure regulator having a high pressure end and a regulated end, the pressure regulator adapted to provide an output having a constant pressure over a range of pressures received at the high pressure end; a charging cylinder adapted to carry a compressed gas therein for engaging the regulator at a high pressure end thereof; and an assembly for engaging the regulated end of the regulator and the storage cylinder for providing a regulated pressure to a head space of the storage cylinder such that the firing unit expels a spray from the storage cylinder under compressed gas when the trigger of the firing unit is depressed and for engaging the dip tube extending into the storage cylinder;
wherein the charge delivery tube is adapted to engage the assembly so as to fluidly connect to the dip tube and connect the charge of the storage cylinder at a first end and the trigger at the second end, the trigger for selective expelling the spray composition.
