Definitions

  • the present invention relates to a discharge structure of a compressor for compressing and discharging a fluid, a nonreturn valve therefor and a compressor therewith.
  • a compressor is used for compressing and discharging various fluids such as a coolant and in general applied to an air-conditioner and such.
  • the compressor is provided with a discharging valve. Open and close movement of the discharging valve may cause pulsating flow of the fluid. In a case where a nonreturn valve is applied to the discharging valve, pulsation may get worse.
  • Japanese Application Laid-open No. H11-315785 in paragraphs 0035 through 0040 discloses an art of a compressor which reduces such pulsation.
  • the compressor is provided with a throttle formed in a unitary body with a discharge port of a housing, which contributes to reduction of pulsation.
  • US 2002/192091 according to the preamble of claim 1 discloses a discharge structure having a check valve for a compressor comprising an inflow opening connected to a discharge port, an outflow opening, a valve body being movable within a recess, and a compression spring biasing the valve body in a steady state and opens at a high pressure in the inflow opening to lift the valve body and allows a flow to outlet part.
  • the throttle is formed in a unitary body with the housing, the housing is unavoidably large-sized and freedom of design is decreased.
  • FIG. 1 a compressor provided with a discharge structure in accordance with a first embodiment of the present invention is shown.
  • the compressor is provided with a housing 1 , a rear-housing 2 joined with a rear end (shown in the right side of Fig. 1 ) of the housing 1, a valve plate 3 disposed between the housing 1 and the rear-housing 2, a shaft 4 rotatably supported in the housing 1, a power transmission part 5 for transmitting power of an engine (not shown) , which is linked with a top end of the shaft 4, a rotational support body 6 fixed with the shaft 4, an inclined plate 7 supported by the rotational support body 6, plural compression chambers (cylinder bores) 8 and pistons 9 respectively reciprocating in the compression chambers 8.
  • a suction chamber 10 and a discharge chamber 11 are formed in the rear-housing 2.
  • the discharge chamber 11 is linked with an external coolant circuit 12.
  • a discharge structure 13 is provided with a tubular flow port R so as to link the discharge chamber 11 with a connection end of a discharge pipe 14.
  • An aperture 15, a nonreturn valve 16 and anti-pulsation means 17 are coaxially arranged in this order on an axis defined by the tubular port R, the discharge chamber 11 and the discharge pipe 14.
  • the aperture 15, the nonreturn valve 16 and the anti-pulsation means 17 form a fluid discharge path.
  • the aperture 15 links the discharge chamber 11 with the nonreturn valve 16.
  • the anti-pulsation means 17 is linked with an outflow end of the nonreturn valve 16.
  • the anti-pulsation means 17 is throttle means for throttling a flow of the coolant gas.
  • the throttle means is provided with a throttle member 19 having a throttled through-hole 18 substantially at a center thereof.
  • the throttle member 19 is disposed between the nonreturn valve 16 and a retainer (C-ring) 20 for fixing the nonreturn valve 16.
  • the inflow opening 25 is linked with the discharge chamber 11 via the aperture 15.
  • the outflow openings 21 are formed on and penetrate a side wall of the tubular member at substantially even intervals (at every 90 degrees in the present embodiment) .
  • An O-ring 45 is fitted on an outer periphery of the tubular member 26 near to the inflow opening 25 to seal a clearance between the tubular member 26 and the tubular flow port R.
  • the cap member 27 is composed of a disk 28 attached to the second end (the upper end shown in Fig. 3 ) of the main body 22, a spring supporter 29 projecting toward the first end and disposed at a center of the disk 28 and plural (four in the present embodiment) projections 30 formed on an outer periphery of the disk 28 at even intervals.
  • the projections 30 respectively project outward and upward so as to form flow paths therebetween.
  • the projections 30 further project downward so as to be capable of latching with the outflow openings 21 of the main body 22.
  • valve body 23 When assembling the nonreturn valve 16, first the valve body 23 is inserted into the second end of the main body 22. Second one end of the elastic body 24 is made to abut on the valve body 23 and another end is engaged with the spring supporter 29. In this state, the disk 28 is installed on the second end of the main body 22 and the projections 30 are latched with the outflow openings 21 of the main body 22.
  • the fluid in the discharge chamber 11 of the rear-housing 2 is capable of flowing through the aperture 15 and the inflow opening 25 and out of the outflow opening 21.
  • the fluid further flows through a flow path between the outer periphery of the tubular member 26 and the inner periphery of the tubular flow port R and splittingly flows through the flow paths formed between the projections 30.
  • the split fluid gathers above the center of the disk 28 and flows out of the throttled through-hole 18.
  • the pulsation of the fluid is twice reduced at the aperture 15 and the throttled through-hole 18 because both the aperture 15 and the throttled through-hole 18 are throttled.
  • the fluid flows through the retainer 20 and the discharge pipe 14 and is delivered to the external coolant circuit 12.
  • the discharge structure 13 in accordance with the first embodiment is capable of doubly reducing the pulsation of the fluid by means of both the aperture 15 and the throttled through-hole 18. Because the discharge structure 13 by itself has the throttle member 19 with the throttled through-hole 18, unlike the prior art, the housing 1 of the compressor is not necessary to have any anti-pulsation means. This leads to avoidance of large-sizing and increase in freedom of design. Moreover, because the throttle member 19 is disposed adjacent to the nonreturn valve 16, alignment of the nonreturn valve 16 is unnecessary to be accomplished with high precision.
  • the discharge chamber 11, the aperture 15, the nonreturn valve 16 and the anti-pulsation means 17 are coaxially arranged in this order on the axis from the discharge chamber 11 to the discharge pipe 14, thereby the flow path defined by the aperture 15, the nonreturn valve 16 and the anti-pulsation means is formed to be a simple structure. This leads to saving a space in the rear-housing for housing these members. Furthermore, the fluid flows along the axis in a substantially linear way, thereby flow resistance except for those by the aperture 15 and the throttle member 19 can be reduced.
  • a discharge structure 31 in accordance with the second embodiment differs from the aforementioned discharge structure 13 in accordance with the first embodiment mainly in that anti-pulsation means 32 is provided with a throttle member 33 formed in a unitary body with a retainer for fixing the nonreturn valve 16.
  • the other members are substantially the same as those of the first embodiment.
  • the throttle member 33 has a throttled through-hole 34 substantially at a center thereof.
  • the throttle member 33 is further provided with plural latching pieces 35 projecting from an outer periphery thereof toward that where the fluid is discharged, which are capable of latching with the rear-housing 2.
  • the latching pieces 35 form flow paths therebetween.
  • the throttle member 33 is further provided with a columnar member 36 so as to keep a gap 37 between the throttle member 33 and the nonreturn valve 16.
  • the fluid out of the nonreturn valve 16 flows through the gap 37 to gather below the center of the throttle member 33 and flows out of the throttled through-hole 34.
  • the pulsation of the fluid is reduced at the throttled through-hole 34. After the reduction of the pulsation, the fluid flows through the discharge pipe 14 and is delivered to the external coolant circuit 12.
  • the projections 30 may be used to keep the gap between the throttle member 33 and the cap member 27.
  • the discharge structure 31 in accordance with the second embodiment is capable of reducing the pulsation of the fluid by means of the throttled through-hole 34 formed in the throttle member 33. Because the discharge structure 31 by itself has the throttle member 33, unlike the prior art, the housing 1 of the compressor is not necessary to have any anti-pulsation means. This leads to avoidance of large-sizing and increase in freedom of design. Moreover, because throttle member 33 is disposed adjacent to the nonreturn valve 16, alignment of the nonreturn valve 16 is unnecessary to be accomplished with high precision.
  • throttle member 33 is formed in a unitary body with the retainer for fixing the nonreturn valve 16, installation of these members can be accomplished at once.
  • a discharge structure 38 in accordance with the third embodiment is provided with a deflection plate 39 on the cap member 27 at an outflow side relative to the cap member 27 as shown in Fig. 8 .
  • the deflection plate 39, the disk 38 and the projections 30 define throttled ports 40 to function as anti-pulsation means.
  • a flow path 42 is formed between the tubular member 26 and the tubular flow port R; radial flow paths 41 are defined by the cap member 27 and the deflection plate 39; and a central through-hole 44 is formed in the deflection plate 39.
  • the central through-hole 44 of the deflection plate 39 may be smaller in cross section than the flow path 42 and the radial flow paths 41.
  • the radial flow paths 41 are smaller in cross section than the flow path 42 and the central through-hole 44 of the deflection plate 39.
  • the deflection plate 39 may be formed in a unitary body with the retainer 20 or the nonreturn valve 16.
  • the present invention can be applied to wide uses such as air-conditioners for vehicles, machines for commercial use and industrial machines, because the present invention provides a compact compressor which may be applied to general use and has facility with respect to installation.
