Definitions

  • the present invention relates to an air or compressed gas distributor placed or not at the end of a cylinder piston and which, after its activation, has an automatic operation caused by the pressure and the depression of the air in the jack .
  • the present invention also relates to an embodiment in the form of kit or integrated into any moving assembly moved by compressed air or pneumatic pressure (possibly pressurized gas other than air).
  • compressed air distributor Many types are already known, but they are all actuated by mechanical, electromechanical or electronic means without having the possibility of closing and automatic opening of the compressed air supply as a function of the pressure / vacuum of the compressed air. air, as well as automatic exhaust air when returning the cylinder piston.
  • the compressed air by a mechanical means implemented by the operator at the time of loading (hand pumping), or a compressed gas, such as that the carbon dioxide contained in a cartridge is distributed from a storage chamber to the barrel of the weapon. This distribution is done by means of a valve operable by pressure on the trigger.
  • US-A-5,400,536 discloses a rotary, dual-acting gun having a ram in line with the barrel for firing projectiles. At the time of firing, a rod secured to the piston of the cylinder is struck by the dog, which opens the valve and releases a gas under pressure in the barrel.
  • US-A-5,613,483 discloses the assembly of a piston and a cylinder for a gas weapon.
  • the piston can move back and forth between a loading position and a firing position.
  • the cylinder has two chambers through which the piston moves.
  • the piston When the piston is in the loading position, the cylinder is in communication via the first chamber with a device for supplying gas under pressure. This position of the piston prevents any communication between the two chambers.
  • the piston rod is provided with a passage section at the contact with the cylinder which extends longitudinally.
  • US-A-5,363,834 discloses a weapon having a first mode of operation for the propulsion of a projectile by compressed gas contained in a cartridge and a second mode of operation for the propulsion by compressed air generated by a pumping mechanism manual.
  • the aim is to be able to remedy a failure of the compressed gas supply system (dioxide of carbon).
  • a manual switch actuated by the shooter to switch from one operating mode to another, by contacting a storage chamber is with the compressed gas, or with the compressed air obtained by pumping.
  • the dog Upon firing, the dog hits a piston piston member that releases air or pressurized gas to the barrel of the weapon.
  • British Patent GB-A-713 044 discloses an air gun comprising a chamber filled with compressed air which can, via an evacuation valve, enter the barrel at the rear of a projectile and allow the discharge of the weapon.
  • the discharge valve is integral with a piston which also carries a balancing valve, the first valve opening towards the inside and the second valve opening towards the outside of the chamber, one or the other.
  • the other of the two valves is further provided with an elastic packing ring whose edges are in closed contact with the adjacent parts, thus protecting them from possible damage.
  • the present invention aims to provide a cylinder and its compressed gas dispenser, preferably in line, fully automatic operation after activation through an initial pulse.
  • the invention has the complementary purpose of providing, for certain applications, such a jack and its distributor in kit form, easily adaptable to existing equipment.
  • the invention also aims to provide such a dispenser that is compact, that is to say, causing a very small increase in the length of the cylinder by integrating the dispenser, simple and easy to implement.
  • the invention aims to provide an automatic pneumatic dispenser for use in a large number of technical fields and not limited to the specific sector of armament.
  • the present invention relates to a device with automatic operation for the distribution of compressed gas, comprising a jack consisting of a cylinder in which a piston with a piston head can slide, and a rear end a distributor, comprising a dispenser support formed by a closable front end of said cylinder and having a compressed gas inlet, a chamber capable of containing a compressed gas being dynamically located between the dispenser support and the piston head.
  • the device comprises a valve capable of opening and closing along the axis of the cylinder and a double seal allowing the opening and closing of the compressed gas inlet, the valve being provided with a return spring such as in equilibrium, it is detached from the double seal, rear side, the double seal being provided with a return spring such as equilibrium, it closes the arrival of compressed gas.
  • the piston head can come into contact with the valve at the front of the cylinder, which causes the valve to move back together and the double seal to stop against the distributor support, which causes admission by an inlet. compressed gas in the chamber.
  • the pressurized gas escapes either by leaving the piston out of the cylinder, or by an orifice arranged in the cylinder, the piston then remaining inside the cylinder.
  • the piston is provided with a return spring which tends to return it to its equilibrium position at the front of the cylinder.
  • the chamber not being or being weakly pressurized and the piston no longer in contact with the valve, the valve and the double seal are in their equilibrium position under the effect of their respective return springs and the valve is detached from the double seal, thereby allowing escape of contained gas in the chamber through an orifice provided in the wall of the dispenser support, the double seal being in the closed position of the gas inlet under pressure.
  • the initial control of the distributor is made by contact between a front end of the striker and the valve, the rear portion of the striker having been initially struck by the hammer.
  • the dispenser can be controlled by a traction device placed in front of the assembly constituted by the distributor and its jack.
  • the traction device replaces the initial percussion of the piston with a hammer.
  • Another advantage lies in the fact of being able to very easily reset the activation element (hammer) of the distributor by the recoil of the piston.
  • the cylinder / dispenser device of the present invention can be used advantageously with weapons operating pistol type (with slide) or rifle (with bolt).
  • FIG. 1 represents an exploded view with nomenclature according to the control principle by a striker passing through the piston of the jack according to the invention.
  • Figure 2 shows a longitudinal sectional view of the different parts of the cylinder / distributor of Figure 1, as well as a detail view, in the rest position, with the compressed air inlet closed.
  • Figure 3 shows a longitudinal sectional view of the different parts of the cylinder / distributor of Figure 1, as well as a detail view, in the activation position of the distributor for opening the air.
  • Figure 4 shows a longitudinal sectional view of the different parts of the cylinder / dispenser of Figure 1, and a detail view in the retracted position of the piston, with the open compressed air supply.
  • Figure 5 shows a longitudinal sectional view of the various parts of the cylinder / distributor of Figure 1, as well as a detail view, in the piston position out of the cylinder tube, the compressed air inlet being closed.
  • FIG. 6 represents a longitudinal sectional view of the various cylinder / distributor parts of FIG. 1, as well as a detailed view, in the return position of the piston of the cylinder moved by its spring, with the escape of the compressed air through the distributor. .
  • the device for dispensing automatic compressed air according to the invention can be produced in the form of a kit or integrated into any mechanism such as a rifle or a pistol, in particular for firing simulation or in any mechanism depending on the possibilities of exploiting the advantages. of the invention.
  • the initial activation of the dispenser is obtained by percussion of a striker 9 which can slide freely inside a piston 80, by means of a hammer (or dog) 15 which can be an original part of a weapon or device equipped with the automatic compressed air dispenser according to the invention.
  • the percussion is done by pivoting forward of the hammer 15 in a recess of the piston body 8.
  • FIG. 3 shows the open position of the air inlet.
  • a striker 9 which passes through the piston 80 of the cylinder and is controlled by a hammer 15 which strikes the striker 9
  • This latter transmits its linear displacement to the valve 5 of the distributor.
  • the valve 5 then comes into contact with the distributor seal 3, the latter moving to the left, which allows the compressed air to pass between the attached assembly seal 3 - valve 5 and the piston head 11 of the cylinder .
  • the entry of the compressed air into the cylinder 1 has the effect of maintaining, by the pressure of the air which is compressed therein, the assembly 3.5 in the position with a left stop against the distributor support 2, the air inlet 14 remaining open and also effect the integral retraction of the various parts 8,9,10,11 component piston 80 of the cylinder to the right ( Figure 4).
  • Figure 5 shows the position of depressurization in the cylinder.
  • the latter can either out of the cylinder or cylinder tube 1 or remain in the cylinder through a side air exhaust 12 in the cylinder tube 1. In both cases, this has the effect of reducing the pressure in the cylinder tube 1 and, at the same time, to reduce the pressure on the seal valve assembly 3 and valve 5.
  • the assembly 3.5 can then, under the effect of respective springs 4.6 of the two parts 3.5 resume its initial position to the right ( Figure 6), which closes the compressed air supply through the circular double seal of the distributor 3. This also allows the exhaust of the air still in the chamber 10 during the return of the piston 80 of the cylinder which moved by its spring (not shown) returns to its initial rest position to the left.
  • the striker portion 9 could be absent and be replaced by direct contact between the piston 80 of the cylinder and the valve 5, which would have the effect that, when closing the cylinder to the left, it would automatically be available all functions illustrated in Figures 3 to 6. To stop in this configuration, the operating cycle, simply interrupt the piston of the cylinder tube before its contact with the valve 5.
  • the device of the invention can be made in the form of a kit to be mounted directly in shooting simulation weapons or be adaptable to any other mechanism, either in a kit, or integrated into a more complex set, requiring or not modifications of the device original.
