Abstract
The utility model provides a compressing machine which can reduce the flowing-through resistance and improve the working efficiency in a refrigerant pipeline at the downstream side of a throttle part of an exhaust gas silencer. Namely, for the refrigerant pipeline at the downstream side along the flowing direction of a refrigerant of the throttle part (14a), the diameter is gradually increased towards the downstream side. Therefore, the refrigerant passing through the throttle part (14a) flows through along a wall surface (14b) of the refrigerant pipeline at the downstream side along the flowing direction of the refrigerant of the throttle part (14a), thereby not only reducing the flowing-through resistance, but also improving the working efficiency by inhibiting the flowing turbulence of the refrigerant at the downstream side of the throttle part (14a).

This compressor as shown in Figure 1, possesses: the motor 40 of the press part 20 of housing 10, compressed refrigerant, the live axle 30 of drive compression portion 20, rotating driveshaft 30.
Inhaling silencer 25 is located at the top of cylinder head 23.Inhaling silencer 25 is made of the parts that the synthetic resin manufacturing forms, and as shown in Figure 2, is formed with the space of extending to substantially horizontal.Axial central part below inhaling silencer 25 is provided with the refrigeration agent outlet pipe 25a that the refrigeration agent that makes in the inhaling silencer 25 flows through suction chamber 23a.Refrigeration agent outlet pipe 25a is configured to extend downwards below inhaling silencer 25, is provided with refrigeration agent outflow opening 25b in the lower end.Refrigeration agent outlet pipe 25a inserts in the suction chamber 23a.In addition, axial distolateral below inhaling silencer 25 is provided with and makes refrigeration agent flow into refrigeration agent inflow entrance 25c in the inhaling silencer 25.At refrigeration agent inflow entrance 25c, be connected with refrigerant suction pipe 13.
Exhaust silencer 26, as shown in Figures 3 and 4, the parts that formed by the metal manufacturing of hollow cylindrical constitute, and the side at cylinder block 21 is provided with central shaft to substantially horizontal.Exhaust silencer 26 is made of open muffler body 26a of the end sealing the other end and the lid 26b that is fixed on muffler body 26a and seals the other end opening of muffler body 26a by soldering.Muffler body 26a and lid 26b for example form by pull and stretch processing cold rolled sheet respectively.On the top of lid 26b, be connected with the refrigeration agent that makes in the drain chamber 23b and flow through refrigeration agent intake channel 26c in the exhaust silencer 26.In addition, below the joint of the refrigeration agent intake channel 26c of lid 26b, be connected with refrigeration agent discharge pipe 14 as the refrigeration agent outlet pipe.That is, refrigeration agent intake channel 26c and refrigeration agent discharge pipe 14 are arranged on the one side of the lid 26b side of exhaust silencer 26.In addition, refrigeration agent intake channel 26c and refrigeration agent discharge pipe 14, its end is outstanding in exhaust silencer 26 respectively.The end of the refrigeration agent discharge pipe 14 in exhaust silencer 26 is provided with and dwindles the restriction 14a that flows into the refrigerant line of refrigeration agent discharge pipe 14 from exhaust silencer 26.
In the compressor that so constitutes, in case rotate together to motor 40 energisings and live axle 30 and rotor 41, then rotating force is sent to piston 24 by the connecting rod 24a that is attached on the eccentric part 30a, and piston 24 moves back and forth in cylinder 21a.In view of the above, the refrigeration agent that flows through refrigerant suction pipe 13 will flow in the inhaling silencer 25 by refrigeration agent inflow entrance 25c, flow into the suction chamber 23a of cylinder head 23 by refrigeration agent outlet pipe 25a.Flow into the refrigeration agent of suction chamber 23a, flow into cylinder 21a and be compressed, flow into drain chamber 23b by discharge orifice 22b by inlet hole 22a.Flow into the refrigeration agent of drain chamber 23b, flow through exhaust silencer 26 and be disposed to refrigeration agent discharge pipe 14.
In above-mentioned compressor,, then can suppress by the variation of the refrigerant flow of cylinder 21a discharging and the pulsation that variation produced of pressure if refrigerant compressed is by exhaust silencer 26 in cylinder 21a.In addition, in above-mentioned compressor,, also can suppress the noise that produces by pulsation simultaneously by suppressing pulsation.And, flow into refrigeration agent in the exhaust silencer 26 when flowing into refrigeration agent discharge pipe 14, by restriction 14a, so can more properly suppress to pulse and by the noise of pulsation generation.In addition, the refrigerant line that is positioned at the refrigeration agent discharge pipe 14 in restriction 14a downstream side forms hemispheric wall 14b, so do not flow through along wall 14b by its mobile can not getting muddled of refrigeration agent of restriction 14a.
In addition, when the lubricant oil that comprises in the refrigeration agent in flowing into exhaust silencer 26 separated in exhaust silencer 26, separated lubricant oil flow back in the refrigerant circuit by the refrigeration agent discharge pipe 14 that is connected refrigeration agent intake channel 26c below.
Like this, according to the compressor of present embodiment, the refrigerant line that the refrigeration agent of restriction 14a flows through the direction downstream side forms, and it is big that its diameter dimension becomes gradually towards the downstream side.In view of the above, the refrigeration agent that passed through restriction 14a is flow through along the wall 14b that the refrigeration agent of restriction 14a flows through the refrigerant line in direction downstream side, so not only can reduce to flow through resistance by the movement disorder that is suppressed at refrigeration agent in the restriction 14a downstream side, can also increase work efficiency.
In addition, restriction 14a is formed at the end of refrigeration agent discharge pipe 14.In view of the above, needn't process in the exhaust silencer 26, just can in exhaust silencer 26, constitute restriction 14a as long as carry out refrigeration agent discharge pipe 14 is connected in the processing of exhaust silencer 26, so can reduce process time.
In addition, restriction 14a forms because of the end that forms the hemispherical refrigeration agent discharge pipe 14 that seals by opening.In view of the above, the end of refrigeration agent discharge pipe 14 needn't be installed in, number of components and built-up time can be reduced by the miscellaneous part that soldering etc. will be formed with restriction 14a.
In addition, refrigeration agent discharge pipe 14 is connected near the joint of refrigeration agent intake channel 26c of exhaust silencer 26.In view of the above, needn't increase the piping length of refrigeration agent discharge pipe 14 and refrigeration agent intake channel 26c, refrigeration agent discharge pipe 14 and refrigeration agent intake channel 26c can be connected exhaust silencer 26, so can reduce manufacture cost by the use amount that reduces the pipe arrangement material.
In addition, refrigeration agent discharge pipe 14 is connected the below of the refrigeration agent intake channel 26c of exhaust silencer 26.In view of the above, can make in exhaust silencer 26 by refrigeration agent discharge pipe 14 to flow back in the refrigerant circuit, so can prevent to rest in the exhaust silencer 26 with the refrigeration agent separated lubricating oil with the refrigeration agent separated lubricating oil.
In addition, in the above-described embodiment, the closed type electromotive compressor in the compressor has been described, but has been not limited in this.So long as possess the compressor of exhaust silencer, even if for example type semienclosed motor compressor or utilize open compressor of other drive power source etc. also can be used.
In addition, in the above-described embodiment, illustrated by connecting rod 24a the rotating force of live axle 30 is sent to the reciprocal compressor that piston 24 moves back and forth, but be not limited in this.For example, also can in the compressor of the different institutions such as tilted-plate compressor that move back and forth piston by swash plate, use the utility model with the common rotation of live axle.
