Abstract
The invention relates to a gas actuating cylinder, aims to overcome the defect that the conventional gas actuating cylinder cannot meet requirements of occasions for low thrust especially micro-thrust, and provides a gas actuating cylinder capable of outputting micro-thrust and suitable for occasions requiring for low thrust. The gas actuating cylinder comprises an igniter, a casing, a propellant, a barrel, a piston rod and a micropore-containing isolating device, wherein the micropore-containing isolating device is arranged in the middle of the casing; the igniter, the casing and the isolating device are connected sequentially and form a combustion chamber, and the propellant is arranged in the combustion chamber; and the other end of the micropore-containing isolating device, the casing, the barrel and the piston rod are connected sequentially and form a buffer chamber, the micropore-containing isolating device can adopt a partition board, a sleeve and the like, and a micropore is formed in the isolating device and communicates the combustion chamber with the buffer chamber. During work, the igniter is ignited, then the propellant is ignited, gas enters the buffer chamber to push the piston rod to move outward with the increase of the pressure in the combustion chamber, and variable thrust is generated.
Description
Technical field
The present invention relates to a kind of combustion gas pressurized strut, especially a kind of combustion gas pressurized strut that microthrust can be provided.
Background technology
At present, existing combustion gas pressurized strut comprises igniter, housing, propellant, cylindrical shell, piston rod, when such combustion gas pressurized strut work, rely on combustion chamber inner high voltage combustion gas to promote piston rod and produce thrust, there is the working time short, the advantage that thrust is large, but the propellant of such combustion gas pressurized strut light and need certain pressure intensity, along with the restriction of structural strength, size, the thrust of combustion gas pressurized strut can not be very little, therefore this combustion gas pressurized strut particularly demand of microthrust occasion of low thrust of can not satisfying the demand.
Summary of the invention
The present invention has overcome the existing combustion gas pressurized strut particularly deficiency of the demand of microthrust occasion of low thrust of can not satisfying the demand, and provides a kind of and can export microthrust, meets the needs of the combustion gas pressurized strut of the little occasion of thrust.
For solving the technical problem of above-mentioned existence, the present invention includes igniter, housing, propellant, cylindrical shell, piston rod, containing the spacer assembly of micropore, the described spacer assembly containing micropore is arranged on housing middle part.Igniter, housing, connect successively containing the spacer assembly of micropore, jointly form combustion chamber, propellant is arranged in combustion chamber.The other end, housing, cylindrical shell, the piston rod that contain the spacer assembly of micropore connect successively, jointly form surge chamber, can adopt dividing plate, sleeve etc. containing the spacer assembly of micropore, are provided with micropore on spacer assembly, are communicated with combustion chamber and surge chamber.Igniter is arranged on housing one end, and is threaded with housing, causes energy loss for preventing that combustion gas from leaking outside, and can between igniter and housing, sealing ring be set.Cylindrical shell one end is threaded with the housing other end, causes energy loss for preventing that combustion gas from leaking outside, and between cylindrical shell and housing, sealing ring is set.Piston rod is arranged in cylindrical shell movably, and baffle ring is set in cylindrical shell, and piston rod is spacing by baffle ring.For preventing that the logical heat transfer form of combustion chamber combustion gas energy outwards runs off, and arranges heat insulation layer in inner walls.Igniter is selected the conventional igniter of propellant, for improving ignition quality and safety, selects insensitiveness electric initiator.Piston rod is flexibly connected with cylindrical shell near one end, combustion chamber, causes energy loss for preventing that combustion gas from leaking outside, and between piston rod and cylindrical shell, sealing ring can be set.Firing point firearm when combustion gas pressurized strut work of the present invention, and then propellant is lighted, along with combustion chamber pressure increases, combustion gas enters surge chamber from combustion chamber, promotes piston rod and moves outward, produces thrust.
The invention has the beneficial effects as follows: owing to adopting above technical scheme, the smooth ignition of propellant and the normal combustion in combustion chamber are ensured, the combustion gas producing can slowly enter into surge chamber by the spacer assembly containing micropore, make the pressure in surge chamber low, can produce the microthrust that promotes piston rod.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.Wherein: 1 is that igniter, 2 is that housing, 3 is that heat insulation layer, 4 is that propellant, 5 is that the spacer assembly, 6 that contains micropore is that cylindrical shell, 7 is that baffle ring, 8 is that piston rod, 9 is that combustion chamber, 10 is that micropore, 11 is that surge chamber, 12 is that the first sealing ring, 13 is that the second sealing ring, 14 is the 3rd sealing ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, igniter 1, as incendiary source, is lighted propellant, and igniter 1 selects to feel immediately electric initiator.Housing 2 is as supporting structure and combustion chamber building block.Propellant 4 is as the power source of combustion gas pressurized strut, produces combustion gas after burning, and propellant 4 is arranged on the end face of spacer assembly 5 that combustion chamber includes micropore.Cylindrical shell 6 makes piston rod slide axially along cylindrical shell interior.Baffle ring 7 limited piston bars skid off cylindrical shell.The power executive component that piston rod 8 is combustion gas pressurized strut.Igniter 1 connects outside igniting holding wire.Igniter 1, housing 2, containing the common composition of spacer assembly 5 combustion chamber 10 of micropore.Containing the common composition surge chamber 12 of spacer assembly 5, housing 2, cylindrical shell 6, piston rod 8 of micropore.Containing on the spacer assembly 5 of micropore, micropore 11 is set, is communicated with combustion chamber 10 and surge chamber 12.Heat insulation layer 3 is arranged on the inwall of housing 2, in the time that combustion gas pressurized strut is worked, can play the effect that prevents that energy outwards runs off.Igniter 1 is threaded with housing, and the first sealing ring 11 is set.Housing 2 is threaded with cylindrical shell 6, and the second sealing ring 12 is set.Piston rod 8 is flexibly connected with cylindrical shell 6 near one end of combustion chamber, and is provided with the 3rd sealing ring 13.
When combustion gas pressurized strut work, first firing point firearm 1, and then light propellant 4, and along with the burning of propellant 4, combustion chamber pressure increases sharply, and combustion gas enters surge chamber 12 by the micropore 11 of the spacer assembly 5 containing micropore, promotes piston rod 8 motions and produces microthrust.
The above, not impose any restrictions the present invention, and every any simple modification of doing according to the technology of the present invention essence, change and equivalent structure change, and all still belong in the protection domain of technical solution of the present invention.
