Title:
ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2019/004367
Kind Code:
A1
Abstract:
An actuator (1) driven by combustion of powder satisfactorily transmits energy for driving an output part to the output part. An output piston part (6) has a specific end face that receives driving energy. A sealing member (8) confines the combustion products in a first space (34) separated by the sealing member. The sealing member has a fixed end portion (35) and a contact portion (34) that is in contact with the specific end face. In a state before the combustion of powder in an igniter (20), the contact portion (34) is located at an initial position. With the combustion of powder in the igniter (20), the contact portion (34) shifts to an operative position with the sliding motion of the output piston part (6) while being in contact with the specific end portion (6a).
