摘要： An explosively propelled piston assembly (EPPA) comprising an optional mounting plate; at least one lower cylinder fastener; a breach bolt with a base and an upward extending member; a breach plate having a plurality of surround openings; a breach gasket having a plurality of openings; a combustion piston with a base, a center opening, and upward extending side wall and a threaded opening; a piston dampening ring; a combustion cylinder having an upper section, a lower section, upward extending members and at least one ventilation bore; and a plurality of threaded plate fasteners. Once the EPPA is assembled, an explosive charge is placed into the EPPA. The charge is then activated which produces a contained explosive force that actuates the piston, causing the piston to extend outward, applying the force onto an object in contact with or adjacent to the EPPA. The force can be used to produce pushing, flipping, rolling or other movement of the object.

摘要： An actuator has a housing (14), a pyrotechnic charge (17) and a piston (11) which transitions into a pin (12) which in the initial state projects out of the housing (14) and upon ignition of the pyrotechnic charge (17) is retracted at least partially into the housing (14). According to the invention, the piston-pin combination consists of a main body (10) which is made of plastic and has a reinforcing element (13) in the region of the pin (12). The reinforcing element (13) has the shape of a sleeve or tube and surrounds the pin (12). It is form-fittingly connected to the pin (12), for example by the sleeve-like or tubular reinforcing element (13) having a shape (22) for reducing the inner cross-section.

摘要： Electrical switching device are disclosed having a housing with internal component within the housing. The internal components comprise contacts configured to operate, to change the state of the switching device from a closed state, allowing current flow through the switching device to an open state which interrupts current flow through the switching device. A pyrotechnic feature is included that is configured to interact with the internal components to transition the switching device from the closed state to the open state when the pyrotechnic feature is activated. The pyrotechnic feature is configured to trigger in response to levitation between the contacts at elevated current signal flowing through the switching device.

摘要： An actuator assembly includes an actuation member, a release member, and a source of pressurized gas, wherein during a normal mode of operation, the actuation member and the release member are engaged to move in unison, and wherein during an emergency mode of operation, pressurized gas automatically decouples the actuation member from the release member to move separately. In accordance with yet other aspects of the present disclosure, an electro-mechanical actuator includes an electro-mechanical drive system and an integrated backup system operated by a gas generator, wherein when the backup system is activated, the electro-mechanical drive system is decoupled, and the actuator moves to a predetermined position and mechanically locks in place.

摘要： An exemplary method of actuating an operational device includes activating a propellant in a pyrotechnic pressure generator, the pyrotechnic pressure generator comprising an elongated body having a first end, a second end, and a bore extending axially from a barrier to the second end, a piston slidably disposed in the bore, the propellant located in a chamber between the first end and the barrier, a gas outlet orifice through the barrier providing gas communication between the chamber, and a port at the second end in communication with the operational device; producing a gas in the chamber in response to activating the propellant, the gas escaping through the gas outlet orifice into the bore and the gas applying a force to the piston; moving the piston in a stroke from a position proximate to the barrier to a position proximate to the second end; communicating a pressure to the operational device that is equal to or greater than an operating pressure of the operational device in response to moving the piston; and actuating the operational device in response to communicating the pressure to the operational device.

摘要： A pyrotechnic gas generator for driving an actuator includes a body defining a combustion chamber housing a main pyrotechnic charge, and an ignitor for initiating combustion of the main pyrotechnic charge. The pyrotechnic gas generator includes at least one delay chamber adapted to communicate with the combustion chamber via at least one inlet orifice, and the delay chamber is provided with at least one outlet orifice for passing gas out from the gas generator. The at least one outlet orifice is provided with a seal adapted to pass from a closed state to an open state when the pressure inside the delay chamber reaches a rupture limit pressure.

摘要： A pyrotechnic actuator mechanism comprises a cover member which includes a first wall member which is opposed to a release portion of an ignition unit, and a second wall member which is connected thereto and which has a free end portion embedded in a fixing member. When an ignition charge contained in the ignition unit is combusted, then the cover member is moved in the propulsion direction so that a predetermined closed space is expanded in the propulsion direction of a piston, and the movement of the cover member is regulated so that a state, in which the free end portion of the second wall member is embedded in the fixing member, is maintained at a maximum propulsion position of the cover member. Accordingly, the residue, which is produced by the combustion of the ignition charge, is preferably suppressed from being discharged or emitted to the outside.
