Title:
ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2019/049314
Kind Code:
A1
Abstract:
In an actuator comprising: an actuator body; an output piston part; an ignition device; and a sealing member, the output piston part has a designated end surface for receiving drive energy, and the sealing member seals a combustion product generated by the ignition device inside a first space on the ignition device side segmented by the sealing member, and also has a fixed end part, and a contact part that contacts the designated end surface. A fixing force of the fixed end part with respect to an inner wall is made bigger by a sliding force of the output piston part at a through hole. Also, in the state before explosive combustion with the ignition device, the contact part is positioned at the start position of the ignition device side with respect to the fixed end part, and by explosive combustion with the ignition device, the output piston part slides in contact with the designated end surface, and moves to an operating position of the output surface side with respect to the fixed end part. By doing this, it is possible to suitably transmit drive energy to the output piston part.
