摘要:
A membrane actuator device includes a housing with an entrance port and an exit port connected by a fluid flow passageway. A gas generation chamber is disposed within the housing, the gas generation chamber comprising a first opening and a gas generating element. A membrane actuation chamber has a second opening and may be defined at least in part by a flexible membrane configured to deflect and affect fluid flow through the fluid flow passageway. A barrier spans the width of the first opening of the gas generation chamber and is disposed in a manner that reduces the likelihood that gas molecules will pass from the gas generation chamber to the membrane actuation chamber.
