Embodiment Construction

[0036] figure 1 The medium device is a pneumatic nail gun for driving a nail 1 into a material 2 . It comprises a main body 3 with a tip guide 4 at the front and a handle and operating handle 5 at the bottom. In order to shoot the nail 1 , the piston 6 is slidably mounted in the cylinder 7 with its head 8 . The piston 6 has a rod 9 for pushing the nail 1 . The body 3 comprises a housing for containing a tank of combustible gas to be injected into a set of combustion chambers before the mixture of gas and air is ignited to propel the piston 6 . The body 3 also includes a cylinder head with a spark plug 10 for igniting the mixture.

[0037] Here, in the body 3, there is a first chamber 11 with a gas inlet hole 12 into which the spark plug 10 protrudes, this chamber being used for precompressing the gas-air mixture and generating the flame. The fan 13 of the electric fan unit is installed in the first chamber 11 . Chamber 11 communicates with the inlet of a tubular intermedi...

Abstract

An apparatus comprising: a first chamber (11) for prepressurizing a combustible gas and generating a flame, a second propelling chamber (15), and means (16) communicating the two chambers, these means being designed to allow the passage of the flame. There is also an intermediate third chamber (14) which compresses and accelerates the flame, communicating with the first and second chambers (11, 15). The present invention can skillfully utilize the advancing piston to close the device.

Description

technical field [0001] The invention relates to a pneumatic device comprising a first chamber with a first volume containing means for igniting a combustible gas and generating a flame, a second chamber with a second volume and means for communicating the two chambers, these means being designed as Allow the flame to pass through. [0002] The invention relates in particular to internal gas dynamic sealing devices in which the piston is propelled by the explosive action of the gas and air mixture to strike a nail through the piston rod; in this case a pneumatic nail gun, or some other fastening device. Background technique [0003] A device with two chambers has several advantages. Of the two chambers, the first is a pre-compression chamber which increases the explosion pressure in the second chamber, the explosion pressure for a volume being proportional to the pressure of the mixture prior to explosion. What happens is that due to the explosion in the first chamber, the ...
