Specific embodiment
As shown in Figures 1 to 5, the present embodiment provides a kind of linear compressor gas deflation assemblies, can be by the straight of the present embodiment
Wire compression machine is assembled with gas deflation assembly is applied to linear compressor.The linear compressor of the present embodiment gas deflation assembly is applied to straight
Wire compression machine can be always ensured that the same of exhaust valve plate 5 and 1 end face cylinder holes of cylinder seat when exhaust valve plate 5 is in close state
Axis degree, the sealing performance between 1 end face cylinder holes of exhaust valve plate 5 and cylinder seat significantly improve.The linear compressor of the present embodiment is used
The cost input of gas deflation assembly is lower, reliability is higher.In addition, exhaust valve plate 5 will not occur when opening, closing as bored bullet
The case where spring steel wire contacts is conducive to the noise performance for optimizing compressor.
The linear compressor gas deflation assembly of the present embodiment, including exhaust valve plate 5, flexure spring 4, cylinder cover 2 and cylinder
Seat 1.
Exhaust valve plate 5 is disc, and 5 outer end face of exhaust valve plate (right side in Fig. 1) is planar structure, outside exhaust valve plate 5
End face as sealing surface so that exhaust valve plate 5 in off position when 1 end face cylinder holes of exhaust valve plate 5 and cylinder seat between closely paste
It closes.Cylindrical first boss 51 is arranged in the middle position of 5 inner face of exhaust valve plate, and the radial dimension of first boss 51 is less than exhaust
Cylindrical second boss 52, the radial direction of second boss 52 is arranged in the radial dimension of valve block 5, the middle position of 51 end face of first boss
Size is less than the radial dimension of first boss 51.Exhaust valve plate 5, first boss 51 and second boss 52 are by nonmetallic composite wood
Material is made.Exhaust valve plate 5, first boss 51 and the forming of 52 three in one of second boss, simplify production technology, and three is formed
Integral structure it is stronger.
The flexure spring 4 of the present embodiment is the flexure spring of linear molded line or the flexure spring of scroll molded line, flexible pellet
The outer dimension and thickness of spring 4 are depending on the design parameter of linear compressor.Flexure spring 4 is disc laminated structure, soft
The middle position of property spring 4 opens up pilot hole, and second boss 52 is assemblied in the pilot hole of flexure spring 4.Wherein, second boss
52 are interference fitted with the pilot hole of flexure spring 4, and it is secured both to simplify Assembly part, and make assembly.
After second boss 52 is assemblied in the pilot hole of flexure spring 4, flexure spring 4, first boss 51, exhaust valve plate
Camber of spring space 7 is formed between 5, the width in camber of spring space 7 is camber of spring bulk C.The edge of flexure spring 4
It can deform towards cylinder seat 1 as deformed flexure spring 4a in the range of camber of spring space 7.
The edge of flexure spring 4 is assemblied in the inside of 2 end face of cylinder cover.In the present embodiment, cylinder cover is set on the inside of 2 end face
Annular gasket 3 is set, annular gasket 3 is made of plastics, and the edge of flexure spring 4 is assemblied in the inside of annular gasket 3.Annular gasket
3 can prevent from generating abrasion between flexure spring 4 and cylinder cover 2, also avoid generating noise.
2 assembly connection cylinder seat 1 of cylinder cover is so that the edge of flexure spring 4 occurs bending and deformation towards cylinder seat 1.This reality
It applies in example, the edge of 2 end face of cylinder cover can be filled through the edge of several 1 end faces of bolt assembly connection cylinder seat in cylinder cover 2
After connection cylinder seat 1, it is easy that the edge of flexure spring 4 is made to occur bending and deformation towards cylinder seat 1.
Cylinder cover 2 overlaps on cylinder seat 1, and when not between assembly is fastened the two, there are primary clearances 8 therebetween, just
The width in beginning gap 8 is initial gap size A, and flexure spring 4 does not deform at this time.After between assembly is fastened the two, two
Primary clearance 8 is eliminated between person, cylinder cover 2 drives the edge of flexure spring 4 to bend towards cylinder seat 1 through annular gasket 3
Deformation.
After the edge of flexure spring 4 occurs bending and deformation towards cylinder seat 1, flexure spring 4 is to restore its original shape, flexible
Spring 4, which presses exhaust valve plate 5, makes the cylinder holes position of 5 outer end face of exhaust valve plate fitting, 1 end face of cylinder seat.
The linear compressor of the present embodiment, which is powered, to be run, and when exhaust valve plate 5 is in close state, exhaust valve plate 5 is soft
Property spring 4 press under, the cylinder holes position of the outer end face of exhaust valve plate 5 fitting 1 end face of cylinder seat, flexure spring 4 can be protected always
Demonstrate,prove the concentricity of exhaust valve plate 5 and 1 end face cylinder holes of cylinder seat, the sealing performance between 1 end face cylinder holes of exhaust valve plate 5 and cylinder seat
It significantly improves.Piston 6 runs compressed gas to the left, and when exhaust valve plate 5 is in the open state, it is soft that exhaust valve plate 5 opens promotion
Property spring 4 have the tendency that restoring its original shape to the left, the intracavitary air-flow of linear compressor is discharged from exhaust valve plate 5, air-flow
Operating path is referring to the airflow channel B in figure.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model, are also answered
Belong to the protection scope of the utility model.
