Technical field
The compressor that the present invention relates to a kind of field particularly relates to a kind of Linearkompressor.It, is avoided the suction valve of above-mentioned piston to be subjected to the pressure of above-mentioned compressor and is damaged by preventing to be subjected to excess pressure in the above-mentioned pressing chamber by the safety valve of piston, constitutes and performance in improving simultaneously.
Background technique
Generally, Linearkompressor (Linear compressor) is meant that the linear drives power of utilizing linear motor is carried out in the straight reciprocating motion piston in cylinder, suction, compressed fluid, and the machine that discharges.
Fig. 1 is the longitudinal sectional drawing of the Linearkompressor of prior art.Fig. 2 is the piston front elevation of prior art.
The Linearkompressor of prior art has cylinder block with cylinder 12 14 that is installed in seal container 10 inside and the bonnet 18 with fluid intake 16 as shown in Figures 1 to 3.Said cylinder body 14 and bonnet 18 support by first vibration damper 20 and second vibration damper 22, and it can be cushioned in above-mentioned seal container 10 inside.
The linear motor 24 of the required driving force of compressed fluid is provided between said cylinder body 14 and the bonnet 18.
Above-mentioned linear motor 24 is made of immobilisation factor and driving factors.Wherein, immobilisation factor is made of outside core 24a and internal core 24b and the coil 24c that forms magnetic field; Driving factors is made of the magnet framework 24e that carries out straight-line magnet 24d and fixed magnets 24d by the magnetic force that forms around the above-mentioned coil 24c.
Above-mentioned magnet framework 24e links to each other with piston 26.The effect of piston 26 is by the straight line motion power that is received by above-mentioned magnet 24d compressed fluid when straight reciprocating motion is carried out in said cylinder 12 inside.
The rear of above-mentioned piston 26 has edge part 26a, its role is to fixing above-mentioned magnet framework 24e, and, between edge part 26a and bonnet 18, be equipped with second spring 30 for the above-mentioned piston 26 of elastic support has disposed first spring 28 between above-mentioned edge part 26a and cylinder block 14.
The rear of above-mentioned piston 26 is round barrel shapes of opening, and inside has the suction passage 26b of incoming fluid, and the front has a plurality of inhalation port 26c.
At this, this inhalation port 26c is that the center is with the certain spacing Off center with the front of this piston 26.
The front of above-mentioned piston 26 has the suction valve 32 of airtight above-mentioned inhalation port 26c, and the fixing above-mentioned suction valve 32 of connected elements such as screw of the front central part by above-mentioned piston 26 central authorities, thereby make it constitute the seal structure of above-mentioned inhalation port 26c according to the interior outside pressure difference elastic bending of above-mentioned inhalation port 26c.
In addition, pressing chamber C the place ahead of said cylinder 14 has the discharge portion 40 of exhaust fluid.
Above-mentioned discharge portion 40 is made of inboard discharge cover 42 and escape cock 46 and outside discharge cover 48.Wherein, inboard discharge cover 42 one sides have discharge orifice 42a, and are fixed on the said cylinder body 14; Escape cock 46 is supported on the above-mentioned inboard discharge cover 42 by discharging spring 44, its role is to the pressing chamber of airtight said cylinder 12; Discharge cover 48 effects in the outside are to make the outside of above-mentioned inboard discharge cover 42 to form certain space.
Above-mentioned outside discharge cover 48 is equipped with the discharge pipe 48a of the fluid that compressed to external world's discharging.
The running of the Linearkompressor of the conventional art of structure is as follows as mentioned above.
When starting above-mentioned linear motor 24, magnet 24d carries out straight reciprocating motion by the interaction of coil 24c surrounding magnetic field, and above-mentioned motoricity is passed to piston 26, thereby make piston 26 between the escape cock 46 of discharge portion 40 and bonnet 18, carry out continuous straight reciprocating motion by magnet framework 24e.
When above-mentioned piston 26 when the direction of discharge portion 40 is advanced, suction valve 32 will be closed by the pressure difference of suction passage 26b and pressing chamber C.
In addition, the fluid in pressing chamber C will be compressed along with advancing of piston 26, and the elastic force that overcomes discharging spring 44 afterwards is discharged into the inboard of inboard discharge cover 42 when opening escape cock 46, be discharged into the external world via outside discharge cover 48 afterwards.
In addition, when piston 26 retreated, above-mentioned suction valve 32 will be opened because of the pressure difference of suction passage 26b and pressing chamber C.
In addition, the fluid among the suction passage 26b of above-mentioned piston 26 will be imported into the inside of pressing chamber C by inhalation port 26C, and escape cock 46 will cut out above-mentioned pressing chamber C by the elastic force of discharging spring 44.
As mentioned above, above-mentioned piston 26 is discharged into extraneous process with it after compressing fluid in the pressing chamber C repeatedly by the advance and retreat of self.
But existing Linearkompressor is done the time spent when its pressing chamber C is subjected to high pressure, and the power that pressure difference inner because of above-mentioned pressing chamber C and suction passage 26b is applied on the above-mentioned suction valve 32 is too big, can cause the damage of above-mentioned suction valve 32.When in order to reduce the damage of above-mentioned suction valve 32, when reducing above-mentioned inhalation port 26c, be drawn in the process among the above-mentioned pressing chamber C by above-mentioned suction passage 26b, flow resistance increases, thereby has reduced its efficient.
This shows that above-mentioned existing Linearkompressor obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that Linearkompressor exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.
