Embodiment
As shown in Figure 1, the present invention includes compression piston 4, suction and discharge valve component and cylinder body 10, the suction and discharge valve component comprises suction valve chip 5 and exhaust valve 9.Compression piston 4 is a hollow article, is equipped with through hole on its inside and outside both ends of the surface.The affixed air aspiration cavity 2 in the exterior edge face of compression piston 4, air aspiration cavity 2 tapered bodies are installed two fins 3 in the chamber, and the hole is established at fin 3 centers, and the size in hole is identical with the internal diameter size of sucking pipe 1.The external diameter difference of two fins is positioned at the diverse location of taper air aspiration cavity.These two fins and taper air aspiration cavity can make the good stability by the gas of Aspirating valves valve block, and have prevented that liquid from entering compression chamber by Aspirating valves and liquid hit phenomenon occurring.The piston of hollow structure communicates with the taper air aspiration cavity.
The small end head face down bonding of air aspiration cavity 2 connects sucking pipe 1; The interior edge face of compression piston 4 promptly compresses on the end face with the affixed suction valve chip 5 of screw.The compression end face is provided with three through holes 11, and wherein first through hole becomes 90 degree with the center line of the 3rd through hole, and the center line of second through hole becomes 45 degree respectively with the center line of first through hole and the 3rd through hole, referring to Fig. 2.
Affixed exhaust cavity 6 on the end face of cylinder body 10, both end faces need seal.Exhaust valve 9 is located in the exhaust cavity 6, and with spring 7 exhaust valve 9 is resisted against cylinder body 10 termination peripheries, and exhaust cavity 6 is communicated with outlet pipe 8.The space in valve body between exhaust valve 9 and the suction valve chip 5 constitutes compression chamber.Air aspiration cavity 2, compression piston 4, compression chamber and suction and discharge valve component all are positioned on the same central axis.The compression piston of hollow becomes to constitute air intake passage with sucking pipe 1 altogether with the taper air aspiration cavity.
The present invention is on the basis that the suction and discharge valve assembly is separated, change its relative position, air suction structure and exhaust structure are placed the both sides of compression chamber respectively, suction valve chip is positioned on the compressing surface of compression piston, the top of outlet valve placement with compression chamber, both are on same axis.In air-breathing process, pressure in the compression chamber is lower, and the working medium of being come by vaporizer enters the compression piston of hollow via sucking pipe 1, relies on the pressure difference of working medium in compression piston lumen and the compression chamber to open suction valve chip, working medium enters in the compression chamber, the beginning breathing process, in this process, the pressure in the compression chamber is less, pressure in the piston lumen is bigger, along with the carrying out of breathing process, working medium constantly enters compression chamber by the piston lumen, and compression piston is moved to the left by the right side of compression chamber; Breathing process finishes the back compression piston and begins compression process, compression piston is moved to the right by the left side of compression chamber, pressure in the compression chamber increases, pressure in compression chamber is even as big as opening outlet valve, in this process, pressure and the pressure reduction in the piston lumen in the compression chamber are increasing, and it is more and more tighter that suction valve chip is closed; In the process of exhaust, the pressure in the compression chamber is higher, and suction valve chip is in closed condition all the time, and this has just been avoided being in contact and heat exchange between the working medium of suction condition and exhaust condition.The suction and discharge valve arrangement of this layout is more suitable for being applied to Linearkompressor, characteristics maximum in the Linearkompressor are exactly that the direct drive compression piston of linear electric motor moves back and forth, the centre does not have other switching mechanism, and therefore, working medium is very in the importing hollow compression piston of direct convenience.
