Abstract
A damper system for a pyrotechnic time delay may comprise: a firing pin; a moveable housing defining a chamber therein; a fixed piston comprising a piston head disposed in the chamber, a first rod extending from the piston head axially outward of the moveable housing, and a second rod configured to fixedly couple to a housing; a first spring extending axially from the moveable housing to the firing pin; and a second spring extending axially from the moveable housing to the firing pin.
Claims20
A damper system for a pyrotechnic time delay, comprising:
- a firing pin;
- a moveable housing defining a chamber therein;
- a fixed piston comprising a piston head disposed in the chamber, a first rod extending from the piston head axially outward of the moveable housing, and a second rod configured to fixedly couple to a housing;
- a first spring extending axially from the moveable housing to the firing pin;
- and
- a second spring extending axially from the moveable housing to the firing pin.
An inert time delay device, comprising:
- a housing having a first axial end and a second axial end;
- an ignition disposed at the first axial end;
- a primer disposed at the second axial end;
- and
- a damper system disposed in the housing, the damper system comprising:
- a firing pin spaced apart axially from the primer;
- a moveable housing spaced apart axially from the ignition;
- a fixed piston comprising a piston head disposed in the moveable housing and a first rod extending from the piston head axially, and outward from, the moveable housing, the fixed piston coupled to the housing;
- and
- a first spring disposed axially between the moveable housing and the firing pin, the damper system configured to initiate an inert time delay from the ignition receiving a pyrotechnic input to the primer sending a pyrotechnic output.
A method of manufacturing an inert time delay device, the method comprising:
- coupling a release arm assembly to a first portion of a housing;
- disposing a damper system in the first portion of the housing, the damper system comprising a moveable housing, a fixed piston, a first spring, a second spring, and a firing pin, the firing pin engaging the release arm assembly;
- coupling a second portion of the housing to the first portion of the housing;
- and
- coupling a primer to the second portion of the housing.
