Title:
GAS CYLINDER ACTUATOR WITH SAFETY DEVICE
Document Type and Number:
Japanese Patent JP2017116104
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas cylinder actuator capable of surely discharging a pressurized gas in safety without causing failure of a stem piston in uncontrolled returning thereof.SOLUTION: An extraction-preventing shoulder 19 and an internal annular protrusion 20 are adapted to cooperate in order to prevent extraction of a head 13 from a tubular jacket 11, the extraction-preventing shoulder 19 deforms to reduce its own diametrical space occupation 23 when it is moved in an axial direction X, so as to allow the relative movement of the corresponding head 13 toward the outside of the tubular jacket 11, and to form a gas discharge passage between the jacket 11, the head 13 and the corresponding sealing element.SELECTED DRAWING: Figure 1
