Abstract
The invention relates to a valve impingement cushioning device of the reciprocating compressor and comprises shell, gas expelling pipe and shock absorption device. In the said shell, there is the compressor. The mover in the compressor and the piston combining with the mover compresses and discharges the secondary refrigerant gas when making straight reciprocating motion. The gas expelling pipe connects with the expelling side of the compressor through the secondary refrigerant transmission pipe with flexibility and sends the secondary refrigerant gas discharged by the compressor into secondary refrigerant pipe of the refrigerating cycle device. The above-mentioned shock absorption device is fixed on the cirumferential surface of at least one side in the inside or outside of the shell and is used in absorbing the shock. The shock absorption device absorbs the shock of shell from the compressing mechanism through gas expelling pipe and thus reduces the shock noise of compressor effectively.
Description
Technical field
The present invention relates to a kind ofly toward the dbl act compressor, particularly relate to a kind of vibration damper that between gas outlet pipe and shell, is provided with absorbing vibration, reduce the noise reduction structure (DEVICE FOR REDUCING NOISE OF RECIPROCATINGCOMPRESSOR) of past dbl act compressor of the vibrating noise of compressor.
Background technique
Generally, reciprocating movement type compressor is that piston comes compression refrigerant gas in cylinder interior do straight reciprocating motion.Fig. 1 is existing sectional drawing toward a preferred embodiment of dbl act compressor; Fig. 2 is the part sectioned view of the stationary state of existing past dbl act compressor gas discharge tube.
As shown in the figure, existing reciprocating movement type compressor is made of frame mechanism 20, reciprocal electrodynamic machine 30, compressing mechanism 40 and resonant spring mechanism 50.Described frame mechanism 20 flexibly supports and is arranged on shell 10 inside; Described reciprocal electrodynamic machine 30 is arranged on the frame mechanism 20, constitutes motor drive mechanism; Described compressing mechanism 40 is connected with the mover 33 of above-mentioned reciprocal electrodynamic machine 30, sucks in the time of with described mover 33 straight reciprocating motions, compression and discharge cold media air; Described resonant spring mechanism 50 is arranged between frame mechanism 20 and the compressing mechanism 40, makes compressing mechanism 40 do resonance motion.
Shell 10 is provided with the gas suction pipe SP that sucks cold media air from refrigeration system (do not have the figure show) and the gas outlet pipe DP that the cold media air that has compressed is discharged to refrigeration system.Described gas outlet pipe DP is connected with refrigerant transport tube 60 in the discharge space S of above-mentioned compressor structure 40.
Above-mentioned gas discharge tube DP forms the L word shape as shown in Figure 2 during front projection, directly welding is fixing after running through the Lower Half of shell.

At this moment, the refrigerant transport tube 60 with absorbing vibration function is absorbed in the vibrations that produce on reciprocal electrodynamic machine 30 and the compressing mechanism 40, thereby reduces the vibrations of compressor to a certain extent.
But, aforesaid existing gas outlet pipe DP toward the dbl act compressor is because directly be fixed on the shell 10, make the torsional vibration (torsional vibration) of refrigerant transport tube 60 be sent on the shell 10, produce the noise of compressor by above-mentioned gas discharge tube DP.
Summary of the invention
In order to solve the problems of the technologies described above, to the purpose of this invention is to provide the vibrations that can reduce to be sent between gas outlet pipe and the shell, thereby reduce the noise reduction structure of the past dbl act compressor of noise.
To achieve these goals, the invention provides a kind of noise reduction structure, it is characterized in that, comprising: shell, gas outlet pipe and vibration damper toward the dbl act compressor.Be provided with compressor body in the described shell, the mover of compressor body and absorb when doing straight reciprocating motion with the mover piston combining, compression and discharge cold media air; Described gas outlet pipe runs through a side that is combined in above-mentioned shell, is connected the discharge side of said compressor self-body by the refrigerant transport tube, and the cold media air that compressor body is discharged is sent in the refrigerant pipe of freezing cycle device; Described vibration damper is fixed on the outer circumferential face of gas outlet pipe of the inboard of shell or at least one side in the outside.
The present invention is toward the noise reducing device of dbl act compressor, on the connection part of shell and gas outlet pipe, be provided with the vibration damper of absorbing vibration, absorb and reduce and be sent to the vibrations of shell, reduce the noise of compressor thus effectively from compressing mechanism by gas outlet pipe.

Embodiment.
Fig. 3 is the sectional drawing of the present invention toward an embodiment of dbl act compressor; Fig. 4 is the part sectioned view of the present invention toward the stationary state of dbl act compressor gas discharge tube; Fig. 5 and Fig. 6 are damping of the present invention (damping) parts embodiment's sectional drawings; Fig. 7 is the part sectioned view of the present invention toward the variant embodiment of dbl act compressor.
The present invention is made of shell 10, frame mechanism 20, reciprocal electrodynamic machine 30, compressing mechanism 40, resonant spring mechanism 50 and vibration damper 100 toward the dbl act compressor as shown in the figure.Described shell 10 connections are provided with gas suction pipe SP and gas outlet pipe DP; Described frame mechanism 20 flexibly supports and is arranged on shell 10 inside; Described reciprocal electrodynamic machine 30 is arranged on the frame mechanism 20, and its mover 33 is made the straight line back and forth movement; The piston 42 of described compressing mechanism 40 is connected with the mover 33 of above-mentioned reciprocal electrodynamic machine 30, compression refrigerant gas when moving reciprocatingly together; Described resonant spring mechanism 50 is arranged between frame mechanism 20 and the compressing mechanism 40, makes compressing mechanism 40 do resonance motion; Described vibration damper 100 is fixedly installed on the connection part of shell 10 and gas outlet pipe DP, absorbs the vibrations that transmit by above-mentioned gas discharge tube DP.
Gas suction pipe SP and gas outlet pipe DP run through welding and fix in a side of shell 10.Wherein gas outlet pipe DP forms the L word shape, and its inside end utilizes rubber-like refrigerant transport tube 60 to be connected compressing mechanism 40 sides.The end in its outside directly is connected on the refrigerant pipe (not showing among the figure) of freezing cycle device.
As shown in Figure 4, vibration damper 100 inserts and is fixed on the gas outlet pipe DP, is located at the inside and outside both sides of shell 10.Contact with the internal face of shell 10 and outer wall respectively towards a side of shell 10 and fix, help absorbing vibration like this.
As shown in Figure 5, vibration damper 100 forms the shape of C ring (C-ring), the assembling respectively behind shell 10 of gas outlet pipe DP solder bond.Perhaps as shown in Figure 6, vibration damper 100 forms C-clamp (clamp) shape, equally the assembling respectively behind shell 10 of gas outlet pipe DP solder bond.
In addition, as shown in Figure 7, on shell 10, form the perforation 11 that runs through gas outlet pipe DP.Above-mentioned then vibration damper 100 is pressed into above-mentioned perforation 11.This moment, vibration damper 100 materials were preferably made by having stable on heating flexible material.
