Embodiment
In the diagram, densely covered dotted region is that high pressure gas fills region.
As shown in Figure 2, nail gun is in when cock, and high pressure gas is stored in main air cavity 11, in main air cavity 11
High pressure gas acts in the lateral displacement gap travelling valve 2 and choke ring 4 across air passing hole 15；It switchs in air flue 14
High pressure gas enters from travelling 13 tail portion of valve chamber, and due to pressure difference, switch high pressure gas in air flue 14 together with
The spring force of pressure spring 5 pushes travelling valve 2 that choke ring 4 is pressed on the cylinder packing 12 of 16 oral area of cylinder, thus close
The access between main air cavity 11 and cylinder chamber 17 is sealed, piston 3 is in returns state at this time.
As shown in Figure 3, the switch air flue 14 on upper aluminium top cover 1 and atmosphere are connected, and are moved about in high pressure gas travelling valve chamber 13
The high pressure gas of 2 tail portion of valve is discharged, and the high pressure gas in main air cavity 11 passes through air passing hole 15 and acts on travelling valve 2 and resistance always
In lateral displacement gap between compression ring 4, at this time due to pressure difference ends, high pressure gas fills lateral displacement gap and overcomes
Travelling valve 2 is slided and detaches choke ring 4 by the spring force of pressure spring 5, displacement of the coasting distance between travelling valve 2 and choke ring 4
Clearance distance.Travelling valve 2 slides detach choke ring 4 during, high pressure gas still compresses choke ring 4 in cylinder packing 12
Oral area, seals the access between main air cavity 11 and cylinder chamber 17, and piston 3 is in returns state at this time.
As shown in Figure IV, 2 coasting distance of travelling valve is greater than the displacement gaps distance between travelling valve 2 and choke ring 4, travelling
The annular convex platform 41 on sealing ring and choke ring 4 on valve 2, which is formed, to be fastened, and travelling valve 2 continues to slide under drive of high-pressure gas,
And the displacement of choke ring 4 is driven to be detached from cylinder packing 12, the access between main air cavity 11 and cylinder chamber 17 is connected at this time, high pressure
Gas enters cylinder chamber 17 and acts on 3 tail portion of piston, pushes piston 3 to start displacement percussion, choke ring 4 is because by high pressure gas
Body pressure area increases and rises automatically.
As shown in Figure 5, travelling valve 2 and choke ring 4 are displaced to extreme position, between main air cavity 11 and cylinder chamber 17
Access fully opens, and 3 thrust of piston and percussion speed reach maximum, and piston 3 is at this time complete cock, in travelling valve 2
During displacement, the pressure in main air cavity 11 is not lost.
The above embodiments are only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this
Range, therefore, equivalent variations made according to the patent scope of the utility model is still fallen within the scope of the utility model.
