摘要： An actuator includes an outer sleeve with at least a pair of helical slots coiling in a first direction, an inner sleeve with at least a pair of helical slots coiling in a second, opposite direction, and a driver including bearings received through the helical slots of the inner sleeve and into the helical slots of the outer sleeve.

摘要： A combustion powered linear actuator features an actuator body having a first chamber therein and a power piston mounted in the first chamber movable between retracted and extended positions. The power piston has a combustion chamber therein. A first seal about the piston seals the piston with respect to the actuator body. A vent region in the body of increased diameter allows exhaust gases to bypass the first seal and flow into a space between the piston and the actuator body and to then vent out of the actuator body. A second seal proximate the distal end of the actuator body cooperates with another piston seal to seal the annular region when the piston is retracted. The vent region may include a vent gland in the first chamber about the piston defining a vent chamber between the actuator body and the vent gland.
摘要翻译：燃烧动力线性致动器具有致动器本体，其中具有第一腔室，并且动力活塞安装在第一腔室中，其可在缩回位置和伸出位置之间移动。动力活塞在其中具有燃烧室。关于活塞的第一密封件相对于致动器主体密封活塞。增加直径体内的通气区域允许废气绕过第一密封并流入活塞和致动器主体之间的空间，然后从致动器本体排出。靠近致动器主体的远端的第二密封件与另一个活塞密封件协作，以在活塞缩回时密封环形区域。通气区域可以包括围绕活塞的第一腔室中的通气压盖，其在致动器主体和通气压盖之间限定通气室。
