Embodiment Construction
[0024] combine Figure 3-4, a piston-type micro-actuator driven by pyrotechnics mainly includes: a semiconductor bridge ignition component (as an ignition electrothermal sensitive propellant), an electrothermal sensitive work agent (providing power energy), a stepped piston (power actuator), a tube shell etc. The semiconductor bridge ignition component consists of a semiconductor bridge transducer, an asymmetric ceramic electrode plug and a small amount of electrothermal sensitive propellant. The semiconductor bridge transducer is fixed in the trapezoidal recess of the asymmetric ceramic electrode plug, and a small amount of it is filled after bonding the wire. The electrothermal sensitive propellant is made into the pyrotechnic assembly, and the cylindrical charging chamber is filled with a certain amount of electrothermal sensitive work agent, and then the small diameter part of the piston is inserted into the through hole at the bottom of the tube shell, and finally the semi...
