Problems solved by technology

However, when the opening angle of the air door pressing plate is large, the suction between the magnet block and the air door pressing plate will decrease, and the effective area of ​​the gas acting on the air door pressing plate will also decrease, which cannot provide enough closing pressure for the air door pressing plate

Abstract

The invention relates to an ejector device and a damper assembly thereof. The ejector device comprises a shell; the shell is provided with a damper end for introducing air, and the damper end is internally provided with a damper assembly; the damper assembly comprises an end cover, a damper hole is formed in the end cover, and a damper pressing plate which can open and close the damper hole through rotating is arranged in the inner side of the end cover; the damper pressing plate is provided with a pressure bearing face used for forming pressure difference on the damper pressing plate to control opening and closing of the damper pressing plate; and an elastic device is arranged on the inner side of the damper pressing plate and applies acting force which can force the damper pressing plate to close to the damper pressing plate. When the opening angle of the damper pressing plate is large, the acting force provided by the elastic device to force the damper pressing plate to close is also greater, and it can be ensured that the damper pressing plate has sufficient closing pressure under the circumstance of large opening angle.

Description

technical field [0001] The invention relates to an injection device and a damper assembly thereof. Background technique [0002] The civil aircraft emergency evacuation slide is an important system to ensure the safe and rapid evacuation of the personnel on the aircraft in the event of an emergency landing on the aircraft. It is directly related to the safety of personnel and is an indispensable key device for civil aircraft. Emergency evacuation slides are generally equipped with high-pressure gas cylinders to inflate them and ensure sufficient gas pressure when using the emergency evacuation slide. Therefore, it is necessary to provide an ejection device to use the atmosphere to ensure the gas pressure when the emergency evacuation slide is used. [0003] The Chinese invention patent application with application publication number CN 102039993 A and application publication date of 2011.05.04 discloses an ejection device for lifesaving airbags. The air inlet end of the ga...
