The beneficial effects of the utility model are：
1st, due to being provided with the passage I for running through up and down on piston, it is provided with seal receptacle and passage I pairs on piston
The passage II for answering, is set in check valve sheet, and check valve sheet covering seal receptacle positioned at seal receptacle upper surface on the piston rod
Passage II, vehicle frame pushes compression spring shock absorber, while the piston rod band piston in the air-pressure damping shock absorber is transported downwards
Dynamic, the gas of cylinder base enters cylinder body top through the passage I of piston and the passage II tops opening one-way valve block of seal receptacle；When
When spring cushion pushes vehicle frame upward resilience, the piston rod of the air-pressure damping shock absorber pulls piston upwards, check valve
Piece resilience, by the passage II closings on seal receptacle, the gas at the top of the upward compression cylinder of piston, the quick resilience for eliminating vehicle frame
Power, and then the nuisance vibration power of vehicle is quickly eliminated, vehicle is reached more steady, comfortable operation, simple structure, installation are saved
Shi Shengli, reduce production cost, be quick on the draw.
2nd, due to clamping one-way seal ring between piston and seal receptacle, when piston is moved downward, a small amount of gas of cylinder base
Body enters cylinder body top through gap between one-way seal ring and inboard wall of cylinder block, and during piston upwards, one-way seal ring is pasted completely
Inboard wall of cylinder block is leaned against, prevents cylinder body top gas from entering cylinder base.
