    1534604 Silenced fastener driver tool HILTI AG 6 Aug 1976 [8 Sept 1975] 32857/76 Heading B4C A silenced explosive powered fastener driver tool comprises a piston 8 which is axially displaceable in a combustion chamber 2c between a rearward, firing position and a forward position, one or more exhaust apertures 2b communicating the combustion chamber with a first noise muffling chamber 10a which in turn communicates with at least one further noise muffling chamber 10b via one or more apertures 11a in a diaphragm 11, the last chamber (10c, as shown) having an outlet 13a for the exhaust gases, the volume of the first muffling chamber 10a being 3 to 10 times the volume swept by piston 8 between its rearward firing position and the position shown at which it begins to expose aperture 2b. As shown 3 muffling chambers 10a, 10b and 10c are separated by diaphragms 11, 12 whose apertures 11a, 12a and outlet aperture 13a are staggered relative to adjacent apertures. Preferably the total area of aperture(s) 11a in the first diaphragm is equal to or less than the total area of the apertures in the or each succeeding diaphragm, and the area of outlet aperture 13a is 2 to 10 times the area of aperture(s) 11a. Safety mechanism.-Spring 3 urges barrel 2 forwards, so that the tool has to be pressed against workpiece 4 to bring cartridge 6 into the firing position.

    The invention relates to a powder! pistols and can be used to drive fasteners such as pins during various kinds of installation works. δ
    Known apparatuses for driving pins containing noise suppression chambers that cause a throttling action for outgoing compressed gases [1]. Therefore, on the one hand, only a small effect of damping the noise is achieved, and, on the other hand, parts for damping the noise are subject to strong heating, which prevents the handling of the gun. fifteen
    Closest to the technical nature of the invention is a powder mounting gun for driving pins, containing a cylindrical body, the jamming chambers I0 placed therein, an ignition pin and a spring-loaded cylinder with a working chamber and a hammer [2].
    In this device, in the noise suppression chambers, there is only one step of turbulence of the gas flow in the tube-shaped chamber for noise suppression.
    Repeated changes in the direction of the compressed gases cause a turbulence, which, of course, causes only a non-energetic noise-absorbing effect. In addition, the known silencing chambers with respect to the amount of exhaust gases are made with respect to malmi, therefore, the small openings through which the compressed gases pass are clogged with residues of gunpowder, which reduces reliability and causes heating.
    The aim of the invention is to improve damping, reducing heat and improving the reliability of the gun.
    The goal is achieved by the fact that in the proposed pistol the silencing chambers are arranged in series and connected through diaphragms with openings increasing in area and displaced from one another.
    in addition, the volume of the first in the direction of flow of the compressed gases of the silencing chamber exceeds 3-10 times the volume of the working chamber.
    The drawing shows a powder mounting gun in the clogging position of the pins, a longitudinal section.
    The gun consists of a housing 1, in which an axially moving cylinder 2 is mounted. Installed between the pins 3 from the side of the housing 1, the ratra are lowered before the pin 11 is driven in. This allows to reduce the heat transfer to the cylinder 2 and the recoil momentum.
    After the pressure has been reduced in the first chamber 14, the gases pass through the 'central opening 16 of the diaphragm 17 and enter the second chamber 18. When the gases encounter the next aperture 19 and so / θ her hole 20 offset with respect to one Tel'nykh holes 16, change direction and undergo turbulence.
    Then the gases enter through the opening 20 into the silencing chamber 21 and from here change direction again and again, exit through the outlet 23 in the cover 22 into the atmosphere. In order to avoid a throttling action in the third jamming chamber 21, the cross section of the outlet 23 is much larger than, for example, the cross section of the central hole 16 of the diaphragm 17.
    /; and the nozzle cuff 4 connected by bolts to the cylinder 2, the pressure spring 5 provides, when the gun rises from the material into which the pins are driven, the middle position of the cylinder 2 in the housing 1, i.e. at napi 'fenia clogging. charge 7 is located in the charging chamber 6. Other details of the ignition mechanism, for example, a tension spring for the ignition pin 8, a drain valve, are not shown in the drawing for simplicity. The housing 1 has an opening 9 of an ejection ejection and charge 7. In the cylinder 2 there is a striker 10 with the possibility of movement for ’driving pin 11 into the material. The inlet of the cylinder 2 connects the working chamber 12, i.e. the space between * the initial position of the striker and his position, opening from; verst 13 with a first chamber 14 silencing located in the housing 15 of the muffler. The first chamber 14 t Fuyoyya through the Central hole 16 of the diaphragm 17 is connected to the second chamber jamming. The second jamming chamber 18 is limited by the diaphragm 19, in which there is an opening 20 offset by “” ”>> й. Exclusively of the opening 1.6, the diaphragm separates the second jamming chamber 18 from the third jamming chamber 21,. a closed cover 2’2, an outlet 23 connecting the chamber 21 to the atmosphere.

Case 1 1meet Hole 9 dL of discharge and input of charge 7. In cylinder 2 there is a striker block 10 installed with the possibility of movement for driving the pin 11 into the material. The inlet of the cylinder 2 connects the working chamber 12, i.e. the space between the YU G1er) is the initial position of the striker U and the eld position, which opens the hole 13 with the first jamming chamber 14 located in the housing of the silencer. The first camera 14 fSyaeHriH is the central center; the ojersty 16 of the diaphragm i 7 is connected with the second chamber of the 18 gl. | The second jamming chamber 18 is limited, by the diaphragm 19 in which there is an opening 20, the angle of the head and the hole and of the hole 16, the aperture of the second chamber of the second chamber 18 of the third silencing chamber 21, closed by a hook, is in the center of the hotel and it is a place on the way. 23 connecting chamber 21 to the atmosphere. Thus, all fpw cameras are located in a sequential manner. one after another, and connecting them together, gradually increasing. The volume of the first chamber 14 of the silencing is three to three times larger than the working chamber of 12. h. The pistol works as follows: 8 shots, and in the working position shown, the hammer 10 starts to release the opening 13 of the cylinder 2. .:; Compression In the working behind the striker 10 behind her: chamber 12 gases Pickle through the inlet port 13 into the first 5 of the jamming chamber 14 and expand in it. Chamber 14 serves to receive high-pressure GEREOV 5; the pressure and temperature are reduced before the pin 11 is driven in. This reduces the heat transfer to the cylinder 2 and the recoil momentum. After removing the pressure in the first chamber 14 of the silence, the gases pass through the central hole 16 of the diaphragm 17 and enter the second chamber 18 of the damping. At the same time, the gases hit the next diaphragm 19 and, since its opening 20 is offset from the opening 16, they change direction and are subject to turbulence. Then the gases come through, the hole 20 into the chamber 21 of the jamming and from here, having changed direction, exit through the outlet 23 in the cover 22 to the atmosphere. In order to avoid a throttling effect in the third jamming chamber 21, the cross section of the outlet hole 23 is much larger than, for example, the cross section cent | a1: aperture 16 of the diaphragm 17.
