The end of the piston is usually attached to the system requiring movement from point A to B.
They are often not called a piston actuator or pin pusher because they generally perform a more controlled amount of work. Pyrotechnic thrusters are another form of a pyrotechnic piston actuator. In many applications, the shock of other devices being released is as great or greater than that generated by Piston Actuator. Dampeners can be installed into the Piston Actuators when lower mechanical shock is needed.
PULL THE PIN EXPLOSIVE HOT SAUCE FULL
The pins extract rapidly in most applications creating a mechanical shock when the piston reaches full stroke. Extension length of the piston is controlled by the envelope of the body and work needing to be performed. The gas energy from any of these devices expands rapidly in a confined space resulting in a volume change which drives the piston inside the actuator outwardly. A piston actuator can be actuated by an electrical explosive device and pyrotechnic actuators may also be actuated with a pressure cartridge, mechanical primer initiated device, linear detonation transfer line (SMDC, FCDC, ETL, RDC) or a laser actuated ordnance device (laser initiated squib or detonator). A Piston Actuator retains all explosive hot gasses with the use of various elastomeric seals. The pistons can be designed to lock out once fired. The rate of a desired push can be within a few milliseconds, to much longer times, depending on the need. Key Features How a Pyrotechnic Actuator Works Full function typically occurs in milliseconds from the input of the firing signal. These devices are designed to provide an impulse for a variety of applications both large and small, such as vehicle stage and fairing separation push off, rupturing diaphragms, releasing locking pins, activating latch releases, or activating batteries. Upon initiation, pressure is created causing a piston to stroke. These powerful stroking devices are designed to pack a lot of punch! Piston Actuators can be initiated electrically with a bridge wire device, or with an EBAD FCDCA. Pyrotechnic actuators are used for opening pressure vessels, ejecting flares, unlatching and any other operation where a high energy, relatively short duration, mechanical motion is required. Pressure produced by the cartridge drives a piston creating mechanical motion. The power for such devices is provided by pressure cartridges or gas generators. As an innovator in the motion control sector, we have led application advancement to initiate devices by any number of methods. Achieve your mission-critical goal through an active stroke of an internal rod or piston to induce or control the desired motion.
High Energy Power.Ī pyrotechnic actuator (or explosive piston actuator) can pierce a pressurized vessel (to release gasses), eject flares, unlatch devices, remove devices and push mechanical devices from point A to point B.
