Abstract
The initial piston position regulator is used for reciprocating compressor. The reciprocating compressor includes container, reciprocating motor, frame, piston, valve and resonant spring, and features that the reciprocating motor produces linear reciprocating drive force to drive the piston to reciprocate linearly inside the cylinder under the elastic support of the resonant spring. The initial piston position regulator is set on the resonant spring support or frame to regulate the initial position of the piston. During assembling the compressor, the initial position may be regulated to the designed one, and this can avoid the collision between the running piston or the motor rotor with other parts and raise the reliability of the compressor.
Description

Symbol shown in the figure 1 is a suction pipe, the 2nd, and discharge tube.
Below, the action effect of the piston initial position regulator device of reciprocating movement compressor of the present invention with said structure is elaborated.
At first, the startup to above-mentioned reciprocating movement compressor is elaborated.To above-mentioned back and forth movement formula motor 20 power supplies electric current is flowed on coil 23, by the electric current that on coil 23, flows, between outer stator 21 and inside stator 22, produce magnetic field and permanent magnet 25 interactions, make the rotor that includes permanent magnet 25 carry out the straight line back and forth movement.
The straight line of rotor A comes and goes driving force and sends piston 70 to, makes piston 70 carry out the straight line back and forth movement in the compression volume P of cylinder 60, makes valve portion 80 carry out work simultaneously and suck, compress and discharge gas in the compression volume P of cylinder 60.Above-mentioned reciprocating movement compressor carries out the driving of said process repeatedly.
In addition, the kinetic energy of the straight line back and forth movement by back and forth movement formula motor 20 and the elastic potential energy of spring portion 90 are changed mutually, make vibrating of back and forth movement formula motor 20.
Fig. 4 is that the part of reciprocating movement compressor piston initial position regulator device of the present invention enlarges sectional view.
On the one hand, in the process of the above-mentioned reciprocating movement compressor of assembling, after piston 70 being inserted into the inside of above-mentioned cylinder 60, when the initial stage seat that is inserted in the piston 70 in the cylinder 60 is not inconsistent situation in design, as shown in Figure 4, by situation monitoring parts 100 are inserted or are combined in the spring supporting portion, the primary position of regulating piston 70 is with the position of sound production of primary position in design of piston 70.
Fig. 5 is the sectional view of the reciprocating movement compressor piston initial position regulator device of one embodiment of the invention.
That is to say, under the state that the assembling of piston 70 finishes, if the primary position d of piston 70 is during than the big or little situation in the position of primary position e in the design, as shown in Figure 5, by above-mentioned situation monitoring parts 100 being combined on the side that supports above-mentioned the place ahead spring 92, perhaps above-mentioned situation monitoring parts 100 are combined on the side that supports above-mentioned rear spring 93, with the position of sound production of the primary position e of primary position d in design of piston 70.
Fig. 6 is the sectional view of another embodiment of the present invention reciprocating movement compressor piston primary position controlling device.
As shown in Figure 6, the thickness of situation monitoring parts 100 is formed various forms, to their error size regulate be combined into one or more.
In addition, during compressor operating, because the direction that the pressure of pressurized gas causes piston 70 to be partial to following viewpoint b is a little carried out the straight line back and forth movement.At this moment, because on the primary position of piston 70 is positioned at and makes progress the deviation position of viewpoint a side from the medium line c of last viewpoint a and following viewpoint b, compensated the state that the pressure of pressurized gas is pushed piston 70 by deviation position e during work, the medium line c of piston 70 above viewpoint a and following viewpoint b goes up and carries out the straight line back and forth movement for benchmark between last viewpoint a and following viewpoint b, collides so can prevent piston 70 or rotor A and miscellaneous part.
General compressor is installed on the household electric appliance of refrigerator and air-conditioning etc.In order to make the volume miniaturization of refrigerator and air-conditioning, the volume of compressor must be become littler.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
