摘要

A pyrotechnic device contains a housing having a first end and a second end. A structural component or piston is contained within the housing. A polymer is infused into and/or about the structural component thereby accommodating the immediate ignition of the same by a known initiator/igniter in a known manner, the initiator also contained within the housing.

主权项

1. A pyrotechnic actuator containing:
a housing having a first end and a second end; a piston rod contained within said housing, said piston rod having a third end and a fourth end, the third end proximate to the first end and the fourth end proximate to the second end; a piston cap formed about the third end of the piston rod, the piston cap containing a polymer; and an initiator fixed at the first end and proximate to the third end of the piston for igniting the piston cap upon actuation of the actuator.
