Definitions

  • the object of the present invention is a pre-compressed gas or air operated arm, in particular a weapon suitable for target firing competitions.
  • the present invention aims to make available for the art a pre-compressed air gun, or otherwise pre-compressed gas operated, having a gas outlet control opening valve, sliding coaxially with the barrel axis.
  • the valve is operable to open by rocking means, actuated by a striker sliding in a parallel seat, and opening of the valve relies on oscillating means substantially crosswise with respect to the axis of sliding.
  • a longitudinal section of the casing of a pre-compressed air gun is indicated as a whole at 1; the pistol portion corresponding to the handgrip, whereas the gun barrel disposed, as known, on the opposite side with respect to the handle, is indicated at 2.
  • Barrel 2 disposed along axis AA, is hollow and extends forwardly following a perfectly linear path, suitable for allowing ejection of bullet 3 loaded therein.
  • An internal duct which communicates, and therefore delivers pre-compressed air, or gas, from a reservoir 18 to control assembly 5, where a suitable valve 12, housed in a seat 5C, regulates the gas output as specified more in detail in the following,
  • a seat 7, that is a housing suitable for receiving a striker 8 which can slide along the interior thereof; Sliding movement is activated following release of trigger mechanism 9 of the gun and of a spring 10 having an adjusting screw 11 on a striker 8 side.
  • striker 8 is slidable within seat 7 disposed with axis BB substantially parallel to axis AA of barrel 2.
  • a slider 12 is axially slidable within said cavity 5C; cavity 5C is coaxial with axis AA of barrel 2, and thus slider 12 as well.
  • slider 12 acts as a valve for an outlet hole communicating with barrel 2, said hole, which is indicated at 14A in the figures, forms part of an O-ring 14, for which a corresponding seat is (preferably) formed within assembly 5, as indicated by reference 5A.
  • Slider or valve 12 is normally urged against ring 14 by a spring 15 suitably adjusted. Then, under non-operative conditions, incoming gas from duct 6 is not able to open slider/valve 12 due to the presence of spring 15; slider 12 includes at least a longitudinal hole or passage, carrying and distributing the gas pressure on both sides of slider 12, so as to eliminate a possible thrust effect towards the spring, that is, opening of hole 14A.
  • the gun with assembly 5 fitted in seat 4 of casing 1, will be described.
  • Seal 5B on assembly 5 prevents pressurized air or gas from leaking through communicating seat 7 and seal 5B is situated adjacent and above metal ring 7B.
  • Slider 12 urged against ring 14 by its spring 15, has a cavity 12A at mouth 7A, into which the aforesaid pivot 13 is inserted.
  • Pivot 13 extends outwardly from mouth 13 about half of its length, and is inserted in cavity 12A, whereas the other half is received in seat 7.
  • Pivot 13 is transversely disposed with respect to axes AA and BB and, approximately at the center line thereof, is held by metal ring 7B; in order to facilitate rocking motion, means 13 is supported by evolving means 16, specifically a ball, disposed within seat 7.
  • Pivot 13 is controllable for oscillation by striker 8 and slider 12, or more precisely, by its return spring indicated at 15 in the figures, which goes into action only once the energy of the striker is depleted (water hammer).
  • striker 8 is released and urged by its spring 10 toward pivot 13, causing the lower half of means 13 to advance, and, then, the upper half to go backwards; said rocking motion moves back slider 12, and passage 14A is opened and gas, or air, which was held within control assembly 5, can escape.
