Definitions

  • This invention is related to AIR GUN.
  • Piston with spring - Spring Piston is generally accepted name for an air gun with power-plant made of the standard steel spring which pushes the Compression Piston.
  • the spring is inserted into the Compression Piston and so together they are inserted into the Compression Tube.
  • the spring is compressed by cocking hand/lever until the Compression Piston is cocked. Pulling the trigger, the spring is released to push the Compression Piston which then creates compression in the Compression Tube which shoots a pellet. For each shot of a pellet, the same action is to be repeated.
  • This type of power-plant for air gun is characterized by gradual fatigue of the spring by its use.
  • An air gun with the Standard Spring can reach muzzle velocity of a standard lead pellet which exceeds the speed of sound, and effectively has the upper limit of about 380 m/s or 1250 fps, for the calibre .177 or 4.5 mm.
  • Piston with the pneumatic insert - Gas Ram is generally accepted name for the pneumatic insert which is installed into the Compression Tube in the place of the Standard Spring as the Standard Spring is removed.
  • This type of power-plant is characterized by consistent power and reduction of vibrations, and it lasts longer than the Standard Spring.
  • Pre-charged Pneumatic - PCP is generally accepted name /abbreviation for airguns that use in advance filled air under pressure for shooting pellets.
  • the air is filled in advance under high pressure, into an appropriate cylinder or chamber, in larger quantities, and thus it can be used for multiple shots of pellets.
  • the air is released through the valve directly onto a projectile/pellet.
  • This type of power-plant for air guns is characterized by inconsistency of power and gradual spending of the compressed air and exhaustion of pushing force after firing each pellet and by impracticality of refilling and pumping it, but it is also characterized by minimal vibration which makes a positive impact on accuracy at target shooting.
  • Power-plant with C02 uses cylinders filled in advance with CO2 gas, under pressure, usually for a single use of them. Such cylinders are usually not meant to be refilled.
  • Some more expensive models can use larger containers to be refilled by CO2 as those air guns which are used for shooting colour balls in Paintball games.
  • This type of air weapon is characterized by inconsistency in power and by gradual exhaustion of pushing force, but also produces minimal vibration which has a positive impact on accuracy at shooting.
  • Hollow Connector is a part of the pneumatic mechanism as an innovative element which connects two different power-plants: the power-plant with the Standard Spring and/or with the Pneumatic Piston, together or independently, with the Compression Piston by the help of the Operating Bar-long or short one, because it can accept the Pneumatic Cylinder with the Pneumatic Piston on both sides, and that way enables several types and variants of power-plants in the same air gun.
  • Pressure Chamber is an air container with compressed air placed outside of the Compression Tube and it is connected to that Compression Tube by the Hollow Connector. It is filled with Compressed Air which pushes the Pneumatic Piston which is placed in the Pneumatic Cylinder.
  • Compressed Air is compressed air under high pressure in the Pressure Chamber which pushes the Pneumatic Piston which either by the Operating .Bar-long or by the Operating .Bar-short pushes the Compression Piston.
  • Valve is a part of the pneumatic mechanism which, by pumping or releasing the pressure in the Pressure Chamber, enables change of the pressure and regulation of the pressure in the Pressure Chamber, that is the change and regulation of an air gun power, so enabling complete emptying of the Pressure Chamber for the purpose of changing the type of power-plant or combination of power-plans. It also enables releasing pressure for the purpose of any possible repairs or changes of the sealing rings in the pneumatic mechanism.
  • Pneumatic Piston is the operating piston placed in the Pneumatic Cylinder which, under pressure of the Compressed Air from the Pressure Chamber, pushes the Compression Piston by the Operating Bar-XoTig or The Operating Bar-short.
  • Pneumatic Cylinder is the leading-pipe of the Pneumatic Piston which is under pressure by the Compressed Air from the Pressure Chamber. It can be placed inside of the Pressure Chamber for the purpose of the double power-plant using the Operating Bar-long or inside of the Compression Tube when the Operating Bar-short is used for the purpose of the single, pneumatic, power-plant.
  • Operating Bar - long is a hollow operating-bar in the power-plant mechanism which is pulled through the Hollow Connector and further on through the hollow space in the Standard Spring and operates under pressure of the Pneumatic Piston which is pushed by the Compressed Air from the Pressure Chamber, and that way it joins powers of the Pneumatic Piston and the Standard Spring so operating together and simultaneously as double power which pushes the Compression Piston, where the Operating Bar-long can also operate independently when the Standard Spring is removed.
  • Safety Screw makes one of three safety screws which, together with the bottom screw that connects the Compression Tube to the gunstock, keeping the power plant safely fixed to the Compression Tube and the gunstock.
  • Compression Tube is the part of an airgun between the barrel and the gunstock which encloses the Compression Piston with the Standard Spring.
  • Compression piston is the standard piston in an air gun which, when released by pulling the trigger, produces air compression, in the Compression Tube, which shoots a pellet.
  • Standard Spring is the standard metal spring which is partially placed in the Compression Tube and partially in the hollow space of the Compression Piston.
  • Operating Bat-short is a short hollow operating bar which is connected onto the Pneumatic Piston which is, through the Hollow Connector, connected to the power of the Compressed Air from the Pressure Chamber and so it pushes the Compression Piston, directly and independently, without the Standard Spring.
  • the idea is to place additional pneumatic power-plant, outside of the Compression Tube, and connect it through the Hollow Connecter and by the operating bar with the existing power-plant and so create larger space for accommodation of another and/or stronger pushing mechanism which can operate in combination with the Standard Spring as a double power- plant, of course more powerful one, and also to be able to operate independently as a single power-plant.
  • Primary aim of this invention is to increase power, accuracy and efficiency of standard air guns powered by the Standard Spring by introducing appropriate additional power-plant, which is double power-plant, as it is hereinafter described and illustrated by the drawings.
  • Air Gun Pneumatic Power-Booster makes a specific pneumatic powered device designed for the break barrel air guns with the Standard Spring which converts standard air guns into air guns with double power-plants.
  • This pneumatic power-plant device is filled with compressed air and it is added as an outside extension to the Compression Tube to the existing Standard Spring power-plant. It is cocked and triggered simultaneously with the Standard Spring and that way those two different power-plants are joined and transformed into one and a single operating power which is unlimited, inexhaustible, and it can be regulated and adjusted as needed.
  • the pressure of the compressed air in the Pressure Chamber is constant, and it is inexhaustible when used, and can be used for shooting unlimited number of, one by one, pellets.
  • This pneumatic power-plant either as the power-booster or the double power-plant or as the independent and single power-plant, is superior to all other so far applicable power-plants in production of air guns.
  • the effect of the double-power is enabled by the Hollow Connector, which is fixed to the Compression Tube, and which physically separates two different power-plants, but at the same time, it joins them functionally and that way double their power by the Operating Bar- long which goes through the hollow space of the Hollow Connector and further through the hollow space of the Standard Spring, and that way it connects the power of the Pneumatic Piston with the Compression Piston and so together with the power of the Standard Spring creates one and the same pushing power, that is, an air gun with double power-plant.
  • Air Gun Pneumatic Power-Booster besides its operation in combination with the Standard Spring as the double power-plant, because of the fact that the Pneumatic Cylinder together with the Pneumatic Piston can be removed from the Pressure Chamber and put into the Compression Tube, it can operate also independently, without the Standard Spring, as a single power-plant.
  • Air Gun Pneumatic Power-Booster operated either in combination with the Standard Spring or independently enables that these two different types of power-plants can operate in four different variants of power-plants in the same air gun:
  • the Air Gun Pneumatic Power-Booster it is logical, produces more power in an air gun than the single standard power-plant only with the spring.
  • the Power of the Air Gun Pneumatic-Booster is relatively unlimited, constant, and inexhaustible and can be regulated and adjusted as needed - sport shooting or hunting, softer or harder pellets, lighter or heavier pellets.
  • the Air Gun Pneumatic Power-Booster does not lose its power when it is cocked for long time like the Standard Spring, which is a convenience in hunting.
  • Air Gun Pneumatic Power-Booster in combination with the Standard Spring makes such an air gun, an air gun with double power-plant.
  • the Air Gun Pneumatic Power-Booster can also operate independently in function of the single power-plant.
  • the Air Gun Pneumatic Power-Booster when operated independently, and especially with the Operating Bar-short, because of less mass and shorter sliding way, produces no recoil which is usually produced by the Standard Spring when it is triggered, which makes positive impact on accuracy at sport target shooting.
  • the Air Gun Pneumatic Power-Booster when operated independently, is more silent and doesn't produce vibration which is usually produced by the Standard Spring when it is triggered.
  • the Air Gun Pneumatic-Booster can be installed on majority of already produced and existing models of break-barrel air guns with Standard Spring.
  • the Air Gun Pneumatic Power-Booster can compensate gradual weakening of power of the Standard Spring which is gradually worn by being used.
  • Air guns with the Pneumatic Power-Booster can be produced equally economical in the same way as standard air guns with springs.
  • Air guns with the Pneumatic Power-Booster or only with the Pneumatic Piston and the Operating Bar-short can be easily adjusted to production of new models of air guns, providing minimal adjustment, without essential changes on the existing models or on basic constructions of standard air guns, that means on entire mechanism of such air guns.
  • Air Gun Pneumatic Power-Booster is pumped by ordinary one-stage hand pump which is part of the set, so that the choice of power and/or combinations of it are only matter of choice at one's own demand or purpose.
  • the Air Gun Pneumatic Power-Booster is tested in combination with the Standard Spring as double power-plant, and also independently without the Standard Spring as the single power- plant. It is performed using a standard air gun, calibre 4.5 mm (.177), which, by the Standard Spring, shoots a standard lead projectile/pellet at muzzle velocity of 305 m/s, (1000 fps).
  • Fig. 1 is the cross-section view of the Air Gun Pneumatic Power-Booster mechanism
  • Fig. 2 is the cross-section view of the Air Gun Pneumatic Power-Booster mechanism
  • Figure 1 shows the cross-section view of the Air Gun Pneumatic Power-Booster mechanism in function of the Double Power-Plant It consists of the Hollow Connector 1 , which, by the help of the Screws 8, connects this pneumatic mechanism with the Compression Tube 9, The Pressure Chamber 2 with the Compressed Air 3, the Pneumatic Cylinder 6 with the Pneumatic Piston 5, the Valve 4 for pumping and releasing of the Compressed Air, the Operating bar- long 7 which goes through the Hollow Connecter 1 and through the hollow space of the Standard Spring 11 up to the Compression Piston 10, and that way operates in function of the Double Power-Plant.
  • the Hollow Connecter 1 mechanically separates the two power-plants, the power-plant by the Standard Spring 11 and the Pneumatic Piston 5 and, at the same time, it joins them functionally. These two power-plants are simultaneously cocked and triggered so that way their powers are summed-up into a single and undivided pushing power creating a new air gun with the double power-plant. It is logic, that the smallest power by the pneumatic mechanism added to the Standard Spring 11 makes this combined power-plant more powerful than the Standard Spring 11 alone. Having in mind that the compression of the air in the Pressure Chamber 2 can be relatively unlimitedly increased by pumping, it can be concluded that the power of this combined power-plant unit is also relatively unlimited.
  • This pneumatic unit that is the Air Gun Pneumatic Power-Booster, can also operate independently, without the Standard Springll, as the single pneumatic power-plant.
  • Figure 2 shows the cross-section view of the Pneumatic Power-Booster mechanism in function of the Single Power-Plant by the Compressed Air 3, Hollow Connecter 1, Operating Bar - short 12, but without the Standard Spring 11.
  • the Pneumatic Cylinder 6 and the Pneumatic Piston 5 are removed from the Pressure Chamber 2 and put into the Compression Tube 9 and connected to the Hollow Connecter 1 on the side which is turned towards the Compression Tube 9, and that way they are pulled into the Compression Piston 10 instead of the Standard Spring 11 which is removed.
  • the Pneumatic Piston 5 which is under direct pressure of the Compressed Air 3 from the Pressure Chamber, operates by the Operating Bar - short 12, directly on the Compression Piston 10 which creates the compression in the Compression Tube 9 that shoots a projectile/diabolo.
  • This pneumatic mechanism is superior to other mechanisms when operating independently or in the above mentioned combinations, and it is characterized by relatively unlimited pushing power which is constant and inexhaustible when operated independently or in combination with the Standard Spring 11, so it enables shooting of unlimited number of projectiles, one by one, as well as possibility of regulating and adjusting the pushing power and the power of such an air gun.
  • this invention enables production of the Air Gun Power-Booster as an additional power-plant, for the existing models of air guns, as well as production of new models of air guns with pneumatic power-plant of this type, in more possible variants and combinations, which is stronger, more accurate and more efficient, and which can be produced economically, and so, this way, at the same time, it includes considerable improvement in relation to already known devices of this type, that means already known types of air guns only with the Standard Spring or with already applied pneumatic power-plants of different kinds.
