A firearm suppressor includes a housing to be mounted to a firearm. The housing defines a lumen therein for receiving gases from the firearm. At least one stripper member is disposed in the lumen for engaging and deflecting the gases. At least one one-way flow element is disposed downstream of the at least one stripper member in gas flow direction for permitting a one-way flow of the gases. At least one decompression chamber is disposed downstream of the at least one one-way flow element for reducing energy in the gases. At least one vent valve is disposed downstream of the at least one decompression chamber for expelling the gases into the atmosphere. A mounting system and a mounting method are also provided.

I claim: 1. A firearm suppressor, comprising: a housing to be mounted to a firearm, said housing defining a lumen therein for receiving gases from the firearm; a plurality of stripper cones disposed in said lumen, partially spaced apart from each other to define spacings therebetween and having sharpened upstream edges for engaging and deflecting the gases; at least one non-lumen occluding, one-way flow element having a live hinge disposed downstream of said stripper cones in gas flow direction for permitting a one-way flow of the gases; at least two decompression chambers disposed downstream of said at least one one-way flow element for reducing energy in the gases, each two of said decompression chambers having a respective baffle disposed therebetween, said baffle having slits formed therein for conducting a flow of the gases between said decompression chambers; and at least one vent disposed downstream of said at least two decompression chambers for expelling the gases into the atmosphere. 2. The firearm suppressor according to claim 1, wherein said at least one one-way flow element has a plurality of live hinge valves disposed in a collar covering said stripper cones. 3. The firearm suppressor according to claim 2, which further comprises a support tube disposed within said housing, and a middle support member disposed between said support tube and said live hinge collar, said middle support member having an opening formed therein for the gases. 4. The firearm suppressor according to claim 1, wherein said at least two decompression chambers are three decompression chambers having respective baffles disposed therebetween. 5. The firearm suppressor according to claim 4, which further comprises steel wool filling at least one of said decompression chambers. 6. The firearm suppressor according to claim 1, which further comprises a support tube disposed within said housing, two end caps disposed at ends of said housing outside said support tube, tie rods interconnecting said end caps, and at least one vent valve disposed at one of said end caps for relieving excess pressure. 7. The firearm suppressor according to claim 1, which further comprises a support tube disposed within said housing, at least one torsion spring retainer unit disposed on said support tube, and at least one barrel mount disposed on said at least one retainer unit for mounting the suppressor on a barrel of the firearm. 8. The firearm suppressor according to claim 7, wherein said at least one torsion spring retainer unit includes two torsion spring retainer units, and said at least one barrel mount includes a front barrel mount to be screwed to a threaded button on the barrel and a rear barrel mount to be fused to the barrel. 9. The firearm suppressor according to claim 8, wherein said retainer units have inwardly-projecting locking lugs for holding said retainer units to said support tube. 10. The firearm suppressor according to claim 9, wherein said front and rear suppressor mounts have in-ramps, out-ramps and receivers for said locking lugs of said retainer units, permitting the suppressor to be directly pushed on and pulled off by turning. 11. The firearm suppressor according to claim 8, wherein said rear barrel mount has a mount body with pressurizing parts formed therein, split rings to be disposed within said mount body and a compression driver for expanding and contracting respective ones of said split rings between said mount body and the barrel. 12. The firearm suppressor according to claim 11, which further comprises a fusing fixture to be placed over said rear barrel mount, said fusing fixture having pressure bolts threaded therethrough for applying pressure to said rear barrel mount and fusing said mar barrel mount to the barrel, said fusing fixture being removed after fusing. 13. The firearm suppressor according to claim 11, which further comprises two end caps disposed at ends of said housing, said front barrel mount having a nut disposed at one of said end caps. 14. The firearm suppressor according to claim 1, which further comprises at least one vent valve for venting gases at excess pressure from said lumen, said at least one vent valve having a tube for the gases and a spring cooperating with said tube for absorbing pressure of the gases. 15. The firearm suppressor according to claim 1, which further comprises two end caps disposed at ends of said housing, at least one of said end caps having an inner surface with non-reflective facets disposed thereon. 16. The firearm suppressor according to claim 1, which further comprises two end caps disposed at ends of said housing, at least one of said end caps having an inner surface with an anechoic coating disposed thereon. 17. The firearm suppressor according to claim 1, wherein said plurality of stripper cones each include rounded downstream edges providing aerodynamic surfaces or airfoils for pulling additional gas into said stripper cones acting as a gas trap, and laterally curved spacing ridges maintaining said spacing and steering the gases in laterally curving arcs to decrease an angle of impact with a wall of said housing.
