Specific embodiment
In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, the technical scheme in the embodiment of the application is clearly and completely described.
Referring to Fig. 1, which is the structural schematic diagram of the low impact firer's actuator of one kind provided in this embodiment.
A kind of low impact firer's actuator, which is characterized in that occur including end cap 1, cylinder body 2, casing 3, piston 4, combustion gas
Device 5 and sealing ring 6;
The cylinder body 2 is one end open, the closed hollow cylinder of the other end, and the gas generator 5 is mounted on cylinder body 2
The inside of closed end pushes piston 4 to open end motion to cylinder body 2 for generating combustion gas after firing;
Described sleeve pipe 3 is the hollow cylinder of both ends open, is nested in inside cylinder body 2, and the middle section of casing 3 is opened along its axial direction
There are two above through slots;
The piston 4 includes piston head and piston rod, wherein the piston head is movably arranged in casing 3, the work
Stopper rod is for opening end motion to cylinder body 2 under the driving of piston head;
It is provided on the end cap 1 and is pierced by through-hole outside cylinder body 2 for piston rod, and end cap 1 is mounted on the opening of cylinder body 2
End for realizing the sealing of cylinder body 2, and carries out axially position to casing 3;
The sealing ring 6 is mounted between end cap 1 and the contact surface of cylinder body 2.
It should be noted that directly casing 3 can be pushed into inside cylinder body 2, and casing 3 and cylinder body when installing casing 3
2 interference fits;Meanwhile end cap 1 is threadedly coupled with the exploitation end of cylinder body 2, then 3 one end of casing is withstood by the closed end of cylinder body 2, separately
One end is compressed by end cap 1, effectively prevents the axial movement of casing 3;Piston rod one end connects piston head, and other end connection is external
Equipment generates high-pressure gas and piston 4 is pushed to move, then piston rod completes scheduled function then when gas generator 5 is fired
Can, such as connect the switch of external equipment.
Referring to fig. 2, which is the radial cutaway view of the low impact firer's actuator of one kind provided in this embodiment.It can by Fig. 2
Know, 8 through slots have been opened on the casing 3 of the present embodiment.;
The working principle of the low impact firer's actuator of one kind provided in this embodiment is described below:
It is bonded in the right side of original state, piston head with 2 closed end inner surface of cylinder body;
After gas generator 5 fires, the high-pressure gas of generation pushes piston 4 to move downward along 3 inner surface of casing, then lives
Power cavity is formed between the 2 closed end inner surface of right side and cylinder body of chock plug, and is formed between the left side of piston head and end cap 1
Cushion chamber;
When the right side of piston head moves downward the right end starting point of through slot on casing 3, the gas in power cavity will lead to
It crosses above-mentioned through slot and enters cushion chamber, to greatly reduce the pressure difference between power cavity and cushion chamber, reduce firer's actuator
Impact force;Meanwhile piston 4 also can be such that the volume of cushion chamber constantly reduces during being moved to the left, and also will increase so slow
The pressure for rushing chamber this side further decreases the pressure difference between power cavity and cushion chamber, to reduce the impact of firer's actuator
Power.
It can be seen that the closed end of the piston head of the present embodiment and cylinder body 2 forms power cavity, piston head and the formation of end cap 1
Cushion chamber is provided with the casing of several through slots by being internally embedded in cylinder body 2 in the axial direction, so that piston 4 is hit in gas generator 5
During constantly moving to 2 open end of cylinder body after hair, power cavity passes through the through slot and cushion chamber connection, the gas of power cavity
Into cushion chamber, to greatly reduce the pressure difference between cushion chamber and power cavity, the speed of piston 4 is reduced, is reduced even
A possibility that eliminating piston impact end cap, and then the impact force of firer's actuator is reduced, extend firer's actuator uses the longevity
Life.
Certainly, the invention may also have other embodiments, without deviating from the spirit and substance of the present invention, ripe
Various corresponding changes and modifications can be made according to the present invention certainly by knowing those skilled in the art, but these it is corresponding change and
Deformation all should fall within the scope of protection of the appended claims of the present invention.
