  Please refer to FIG. 12 and FIG. 13, which are exemplary diagrams relating to the operation of the conventional four-compression chamber diaphragm pump of FIGS.

  First, when the motor 10 is powered on, the swinging plate 40 is rotationally driven by the motor output shaft 11, so that the four annular eccentric circular bodies 52 on the eccentric circular body mounting portion 50 are sequentially moved. Always move in the up and down round trip.

  Second, the four pumping pistons 80 and the four piston operating areas 74 in the diaphragm membrane 70 are sequentially driven and displaced up and down by the up and down reciprocating strokes of the four tubular eccentric circular bodies 52.

  Third, when the tubular eccentric circular body 52 moves in the downward stroke to displace the pumping piston 80 and the piston working area 74 downward, the piston disc 98 in the piston valve assembly 90 is pushed into the open state. Thereby, the tap water W flows into the preload chamber 26 through the inlet opening 21 of the pump head cover 20 and the input port 97 of the piston valve assembly 90 (in the enlarged view of FIG. 12, by the arrow extending from the symbol W). Indicated);

  Fourth, when the tubular eccentric circular body 52 moves in the upward stroke and displaces the pumping piston 80 and the piston working area 74 upward, the piston disk 98 in the piston valve assembly 90 is pulled into the closed state. The tap water W in the preload chamber 26 is compressed, and the water pressure in the preload chamber 26 is increased to a range of 100 psi to 150 psi. The resulting pressurized water Wp pushes the plastic backflow prevention valve 94 in the piston valve assembly 90 into the open state.

  Fifth, when the plastic backflow prevention valve 94 in the piston valve assembly 90 is pushed into the open state, the pressurized water Wp in the preload chamber 26 becomes a group for the corresponding sector in the central outlet fitting 92. Is sent into the high compression chamber 27 through the outlet port 95 and then discharged from the outlet opening 22 in the pump head cover 20 (indicated by arrow W in the enlarged portion of FIG. 13).

  Finally, due to the sequential repetitive action for each group of outlet ports 95 for the four sectors in the central outlet fitting 92, the pressurized water Wp is always discharged out of the conventional four compression chamber diaphragm pump, The RO is further filtered by the cartridge, so that the final filtered pressurized water Wp is a type of RO (reverse osmosis membrane) purification device or RO water purification system that is typically installed in a water supply device in a home, recreational vehicle, or mobile home Can be used in

  Referring to FIGS. 14 and 15, the conventional four-compression-chamber diaphragm pump has a long and significant drawback associated with vibration. As described above, when power is supplied to the motor 10, the swing plate 40 is rotationally driven by the motor output shaft 11, whereby the four tubular eccentric circular bodies 52 in the eccentric circular body mounting portion 50 are sequentially moved. While always moving in the up and down reciprocating stroke, the four pumping pistons 80 and the four piston operating areas 74 in the diaphragm membrane 70 are sequentially driven by the up and down reciprocating strokes of the four tubular eccentric circular bodies 52. An equivalent force F always acts on the four piston working areas 74 with the length L1 of the moment arm displaced up and down and extending from the outer raised peripheral edge 71 to the peripheral edge of the annular positioning projection 76 (shown in FIG. 15). ) Thereby, the resulting torque is obtained by multiplying the acting force F by the moment arm length L1 according to the equation “torque = acting force F × moment arm length L1”. The resulting torque directly vibrates the entire conventional four compression chamber diaphragm pump. Due to the high rotational speed of the motor output shaft 11 in the motor 10 up to a range of 800-1200 rpm, the vibration strength caused by the alternating action of the four tubular eccentric circular bodies 52 may be permanently unacceptable.

  To address the shortcomings of the conventional four-compression chamber diaphragm pump, a cushion base 100 having a pair of vanes 101 is always provided as a complementary support, as shown in FIG. It is further covered by a rubber shock absorber 102 to enhance suppression. After installation of a conventional four-compression chamber diaphragm pump in a residential or mobile residential water supply, the cushion base 100 is screwed securely into the housing C of the reverse osmosis membrane purification unit by means of suitable fixing screws 103 and corresponding nuts 104. It is fastened. However, the practical vibration suppression efficiency of the cushion base 100 having the blade plate 101 and the rubber shock absorber 102 only reduces the noise caused by the primary vibration, and the secondary vibration generated by the resonance vibration of the housing C. Does not affect the noise caused by. In fact, the secondary vibration increases the overall vibration noise of the housing C for the reverse osmosis membrane purification unit.

  In addition to the disadvantage of increasing the overall vibration noise of the housing C, a further disadvantage arises from the fact that the water pump P connected to the water outlet opening 22 of the pump head cover 20 vibrates in synchronism with the vibration described above. (Indicated in FIG. 16 and FIG. 16a by a broken line representation of the water pipe P). This synchronous vibration of the water pump P creates additional drawbacks by simultaneously vibrating other parts of the conventional four compression chamber diaphragm pump. As a result, after a certain period, the connection between the water pipe P and the outlet opening 22 is gradually loosened, and the fitting between other parts affected by the vibration is gradually loosened. Water leakage of the compression chamber diaphragm pump occurs. Such further disadvantages associated with overall resonant vibration and water leakage in conventional four-compression chamber diaphragm pumps can be overcome by the conventional methods described above that use shock absorbing cushion base 100 to address primary vibrations. Can not. Therefore, how to substantially reduce all of the drawbacks associated with operational vibrations associated with the four compression chamber diaphragm pumps has become an urgent critical issue.

  As described above, when power is supplied to the motor 10, the swing plate 40 is driven to rotate by the motor output shaft 11, whereby the four tubular eccentric circular bodies 52 on the eccentric circular body mounting portion 50 are sequentially moved. It always moves in the up-and-down reciprocating stroke, and by the up-and-down reciprocating stroke of the four tubular eccentric circular bodies 52, the four piston operating areas 74 in the diaphragm membrane 70 are sequentially driven and displaced up and down, whereby each piston operating area 74 The force F always acts on the bottom side of the.

  On the other hand, with respect to the acting force F exerted on the bottom side of the diaphragm membrane 70, a plurality of corresponding recoil forces Fs are generated, and as shown in FIG. 18, each corresponding piston acting area 74 in the diaphragm membrane 70 is generated. Different components are dispersed throughout the bottom region of the squeeze, thereby causing a squeeze phenomenon caused by the recoil force Fs in a region of the diaphragm membrane 70.

  Of all the dispersion components of the recoil force Fs, the force of the largest component is exerted on the contact bottom surface position P of the diaphragm membrane 70 by the rounded shoulder 57 of the horizontal upper surface 53 of the tubular eccentric circular body 52, Therefore, the squeeze phenomenon at the bottom surface position P is also maximum (shown in FIG. 18).

  Each bottom surface position P of the piston action area 74 of the diaphragm membrane 70 is subjected to a squeeze phenomenon at a frequency of four times per second due to the rotation speed of the motor 10 with respect to the motor output shaft 11 reaching a range of 800 to 1200 rpm. Under such circumstances, the bottom surface position P of the diaphragm membrane 70 is always the first breakage point for the entire conventional four compression chamber diaphragm pump, which not only shortens the service life, but also the conventional four compression chamber diaphragm pump. To stop the normal function of.

  Therefore, there is also a method of substantially reducing the drawbacks associated with the squeeze phenomenon caused by the force F being constantly applied to the bottom side of each piston operating area 74 of the diaphragm membrane 70 by the movement of the eccentric circular body 52 of the four compression chamber diaphragm pump. , Has become an urgent and serious problem.

To do. The sloped upper ring completely eliminates the high frequency oblique tensile forces and squeeze phenomena that occur in conventional tubular eccentric circles. This is because the sloped top ring attaches flatly to the bottom region of the corresponding piston working area for the diaphragm membrane.

  19-28 are illustrations of a four-compression chamber diaphragm pump having multiple effects according to a first exemplary embodiment of the present invention.

  A basic curved groove 65 is disposed circumferentially around the upper side of each operating hole 61 in the pump head body 60 (shown in FIGS. 20-22), while a basic curved projection 77 is provided on the diaphragm membrane. 70 is disposed circumferentially around each concentric annular positioning projection 76 at a position corresponding to the position of each mating basic curved groove 65 in the pump head body 60 on the bottom side of 70 (see FIGS. 24 and 24). 25).

  Thereby, after the pump head main body 60 and the diaphragm film 70 are assembled, each basic curved protrusion 77 on the bottom side of the diaphragm film 70 is completely in the corresponding basic curved groove 65 on the upper side of the pump head main body 60. As a result, the length L2 of the moment arm from the basic curved projection 77 to the peripheral edge of the annular positioning projection 76 on the diaphragm membrane 70 is reduced during operation of the present invention (FIG. 28). Is shown in the enlarged part).

  Further, the cylindrical eccentric circular body 52 in the eccentric circular body mounting portion 50 includes an annular upper surface portion, and the annular upper surface portion is inclined with respect to the horizontal, and the slope is formed between the annular positioning groove 55 and the vertical side surface 56. A top ring 58 with a slope (shown in FIGS. 26 and 27), the top ring 58 with a slope being each tubular eccentric circular body 52 of the eccentric circular body attachment 50 (as shown in FIGS. 3 and 4). In place of the conventional rounded shoulder 57.

  29, 30, 15, and 16 show the moment arm length L2 obtained during operation of the four-compression chamber diaphragm pump having the multiple effects of the first exemplary embodiment of the present invention; It is an illustration figure for comparing with the length L1 of the moment arm obtained during the operation | movement of the conventional 4 compression chamber diaphragm pump.

  During operation of a conventional four-compression chamber diaphragm pump, a moment arm length L1 extending from the outer raised peripheral edge 71 to the peripheral edge of the annular positioning projection block 76 in the diaphragm membrane 70 is obtained (shown in FIG. 15). In contrast, during operation of the present invention, a shorter moment arm length L2 is obtained from the basic curved projection 77 to the periphery of the annular positioning projection block 76 in the diaphragm membrane 70, as shown in FIG.

  The resulting torque in the exemplary embodiment of the present invention is calculated in the present invention because it is calculated by multiplying the same acting force F as that in a conventional diaphragm pump by the shortened moment arm length L2. The torque is smaller than the torque of the conventional 4-compression chamber diaphragm pump. Due to the smaller torque produced in the present invention, the vibration intensity due to the torque is significantly reduced.

  In actual testing of the prototype of the present invention, the vibration strength was reduced to only one-tenth (10%) of the vibration strength with a conventional four-compression chamber diaphragm pump.

  When the present invention is installed in a housing C of a reverse osmosis membrane purification unit buffered by a conventional cushion base 100 having a rubber shock absorber 102 as shown in FIG. 16, a conventional four compression chamber diaphragm pump Undesirable noise caused by resonant vibrations occurring within can be completely eliminated.

  FIGS. 31-33 are exemplary diagrams relating to the operation of a four-compression chamber diaphragm pump having a plurality of effects in the first exemplary embodiment of the present invention.

  First, when the motor 10 is powered on, the swinging plate 40 is rotationally driven by the motor output shaft 11, whereby the four cylindrical eccentric circular bodies 52 on the eccentric circular body mounting portion 50 are sequentially turned. Always move in the up and down round trip.

  Secondly, the four piston operating areas 74 in the diaphragm membrane 70 are sequentially driven and displaced up and down by the up and down reciprocating strokes of the four cylindrical eccentric circular bodies 52.

  Thirdly, when the conventional tubular eccentric circular body or the cylindrical eccentric circular body 52 of the present invention moves in the upward stroke, and the piston operating area 74 is displaced upward, the operating force F is applied to the corresponding annular positioning of the diaphragm membrane 70. A portion between the protrusion 76 and the outer raised peripheral edge 71 is pulled obliquely.

  By comparing the operation of the conventional tubular eccentric circular body 52 shown in FIG. 18 and the cylindrical eccentric circular body 52 of the present invention as shown in FIG. 32, at least the following two differences are apparent. :

  In the case of the conventional tubular eccentric circular body 52 shown in FIG. 18, the largest of all the dispersion components Fs of the recoil force is the edge of the rounded shoulder 57 on the horizontal upper surface 53 of the tubular eccentric circular body 52. This is a component force exerted on the contact bottom surface position P of the diaphragm film 70 located at the portion, and therefore the “squeeze phenomenon” at the point P is also the maximum. Such a non-linear dispersion of the “squeeze phenomenon” enhances the action of pulling diagonally. In contrast, in the case of the cylindrical eccentric circular body 52 as shown in FIG. 32, the variance of the component of the recoil force Fs becomes more linear. This is because the sloped top ring 58 in the cylindrical eccentric circular body 52 is flatly attached to the bottom region of the piston working area 74 with respect to the diaphragm membrane 70, thus reducing the squeeze phenomenon and thus having almost no action of pulling diagonally. Because it is done.

  Furthermore, under the same acting force F, the recoil force Fs is inversely proportional to the contact area, and therefore the magnitude of the dispersion component of the recoil force Fs for the cylindrical eccentric circular body 52 of the present invention as shown in FIG. Is considerably smaller than the magnitude of the dispersion component of the recoil force Fs for the conventional tubular eccentric circular body 52 shown in FIG.

  The improvement of the dispersion linearity of the recoil force component Fs and the reduction of the size thereof form an annular upper surface portion of the eccentric circular body mounting portion 50 inclined with respect to the horizontal, and the annular positioning groove of the eccentric circular body mounting portion 50 As a result of forming a sloped upper ring 58 between 55 and the vertical side 56, it provides at least two advantages. First, this configuration makes it difficult to break the diaphragm film 70 caused by the high frequency squeeze phenomenon. In the conventional arrangement, such a breakage is caused by a rounded shoulder 57 on the normally flat upper surface 53 of the tubular eccentric circular body 52. Secondly, the diaphragm caused by the acting force F generated by the sequential vertical displacement of the four piston working areas 74 in the diaphragm membrane 70 driven by the vertical reciprocating stroke of the four tubular eccentric circular bodies or the cylindrical eccentric circular body 52. The recoil force Fs of the membrane 70 is greatly reduced.

  These benefits provide the following practical benefits:

  1. The durability of the diaphragm membrane 70 for maintaining the high frequency pumping action of the cylindrical eccentric circular body 52 is significantly improved.

  2. Since less current is wasted due to the high frequency squeeze phenomenon, the power consumption of the four compression chamber diaphragm pump is greatly reduced.

  3. Due to the reduction in power consumption, the working temperature of the four compression chamber diaphragm pump is greatly reduced.

  4). Undesirable bearing noise due to the aging of the lubricating oil in the four compression chamber diaphragm pump, which is normally accelerated by high working temperatures, is almost eliminated.

  The results of tests performed on the prototype of the present invention are as follows.

  A. The service life of the tested diaphragm membrane 70 was more than doubled.

  B. The current consumption was greatly reduced from 1 ampere.

  C. The working temperature was greatly reduced below 15 ° C.

  D. The smoothness of the bearing has been improved.

Fully inserted into the groove 791 and the four integral recessed rings 710 (shown in FIG. 112), so that again, during operation of the present invention, the first integral annular groove in the diaphragm membrane 70 A shortened moment arm length L3 from 710 to the periphery of each annular positioning projection 76 is obtained (shown in FIG. 112), thereby providing significantly reduced vibration and preventing displacement. The stability is enhanced by maintaining the moment arm length L3.

  Reference is made to FIGS. 113-115, which are exemplary views of a four-compression chamber diaphragm pump having multiple effects in a variation of the ninth exemplary embodiment of the present invention.

  In this variation, the cylindrical eccentric circular body 52 is modified to an inverted frustoconical eccentric circular body 502 in the eccentric circular body mounting portion 500.

  The frustoconical eccentric body 502 includes an integral inverted frustoconical side 506 and a sloped upper ring 508 that increases the outer diameter of the frustoconical eccentric body 502 but provides an operating hole 61 in the pump head body 60. And the sloped upper ring 508 extends between the annular positioning groove 505 and the inverted frustoconical side 506.

  116 to 118 are exemplary diagrams showing the operation of the “four-compression-chamber diaphragm pump having a plurality of effects” in a modification of the ninth exemplary embodiment of the present invention.

  First, when the motor 10 is powered on, the swinging plate 40 is rotationally driven by the motor output shaft 11, and thereby the four truncated cone eccentric circular bodies 502 on the eccentric circular body mounting portion 500 are sequentially changed. Always move in the up and down round trip.

  Secondly, the four piston operating areas 74 in the diaphragm membrane 70 are sequentially driven and displaced up and down by the up and down reciprocating strokes of the four truncated cones 502.

  Third, when the frustoconical eccentric circular body 502 in the present invention moves in the upward stroke, and thereby the piston working area 74 is displaced upward, the acting force F is applied to the corresponding annular positioning protrusion of the diaphragm membrane 70. A portion between 76 and the outer raised peripheral edge 71 is pulled obliquely.

  Therefore, the inclusion of the sloped upper ring 508 in the eccentric circular body mounting portion 500 is a failure of the diaphragm membrane 70 caused by a high frequency squeeze phenomenon (this failure is usually indicated by a two-dot chain line in FIG. 118). (Which is caused by the rounded shoulder 57 in the tubular eccentric circular body 502), and the recoil force Fs of the diaphragm film 70 caused by the acting force F is greatly reduced. On the other hand, although the outer diameter of the frustoconical eccentric circular body 502 is expanded, the possibility of collision between the frustoconical eccentric circular body 502 and the operation hole 61 in the pump head main body 60 due to the inverted frustoconical side surface 506 is not. Be lost.

  Furthermore, under the same acting force F, the recoil force Fs is inversely proportional to the contact area. The expanded outer diameter of the inverted frustoconical eccentric body 502 increases the contact area between the sloped top ring 508 and the bottom side of the diaphragm membrane 70 (indicated by ring A shown in FIG. 118), thereby All dispersion components of the recoil force Fs for the inverted frustoconical eccentric body 502 of the present invention are further reduced.

  Accordingly, the inverted frustoconical eccentric circle 502 of this embodiment of the present invention provides at least some of the following benefits:

  1. The inverted frustoconical eccentric circular body 502 significantly improves the durability of the diaphragm membrane 70 for maintaining a high-frequency pumping action.

  2. Since less current is wasted due to the high frequency squeeze phenomenon, the power consumption of the four compression chamber diaphragm pump is greatly reduced.

  3. With less power consumption, the working temperature of the four compression chamber diaphragm pump is significantly reduced.

  4). Bearing noise due to aging of the lubricating oil in the four compression chamber diaphragm pump, which is aggravated by aging accelerated by high working temperatures, is almost eliminated.

  5. The service life of the four-compression chamber diaphragm pump is further extended because all the dispersion components of the recoil force Fs for the inverted frustoconical eccentric body 502 of the present invention are reduced.

  119-122 are illustrations of a four-compression chamber diaphragm pump having multiple effects in the adaptation of the ninth exemplary embodiment of the present invention, where the cylindrical eccentric circular body 52 is eccentric. It is replaced by a composite eccentric circular body 502 in the circular body mounting portion 500. The compound eccentric circular body 502 includes a circular body attaching portion 511 and an inverted truncated cone circular body yoke 521 so that they can be detached and separated, whereby the outer diameter of the truncated circular body yoke 521 is expanded, but the pump head body 60 is expanded. Still smaller than the inner diameter of the operating hole 61 in which the circular body mounting portion 511 has two layers, a bottom layer base having an inwardly-facing positional chordal portion 512, and a central internal thread An upper protruding cylindrical portion 513 having a hole 514 is included. The inverted frustoconical circular body yoke 521 includes an upper hole 523, a central hole 524, and a lower hole 525 that are stacked on a corresponding circular body mounting portion 511 and stacked as a three-layered integrated hollow frustoconical structure. Further, it includes an inverted frustoconical side surface 522 and an upper ring 526 with a slope extending from the upper hole 523 to the inverted frustoconical side surface 522, whereby the hole diameter of the upper hole 523 is larger than the outer diameter of the protruding cylindrical portion 513, The hole diameter of the central hole 524 is equal to the outer diameter of the protruding cylindrical part 513, and the hole diameter of the lower hole 525 is equal to the outer diameter of the bottom layer base in the circular body attaching part 511. When the circular truncated cone yoke 521 is placed on the circular body mounting portion 511, the positioning annular groove 515 is formed between the protruding cylindrical portion 513 and the inner wall of the upper hole 523 (shown in FIGS. 121 and 122). ).

  123 and 126 show the manner in which a four-compression chamber diaphragm pump having multiple effects in the above-described adaptation of the ninth exemplary embodiment of the present invention is assembled.

  First, the circular truncated cone yoke 521 is fitted on the circular body attaching portion 511.

  Second, all four annular positioning protrusions 76 of the diaphragm membrane 70 are inserted into four corresponding positioning annular grooves 515 in the four composite eccentric circular bodies 502 of the eccentric circular body mounting portion 500.

  Finally, each fixing screw 1 is inserted through a corresponding step hole 81 in the pumping piston 80 and each corresponding working area hole 75 in the piston working area 74 of the diaphragm membrane 70, and then the fixing screw 1 is inserted into an eccentric circle. The diaphragm membrane 70 and the four pumping pistons 80 are firmly assembled by being fixedly screwed into the four corresponding female screw holes 514 in the four circular body mounting portions 511 of the shape mounting portion 500 (shown in FIG. 123). ).

  125 and 126 illustrate the operation of the above-described adaptive form of a four-compression chamber diaphragm pump having the effects of the ninth exemplary embodiment of the present invention.

  First, when the motor 10 is powered on, the swinging plate 40 is rotationally driven by the motor output shaft 11, so that the four composite eccentric circular bodies 502 on the eccentric circular body mounting portion 50 are sequentially changed. Always move in the up and down round trip.

  Secondly, the four piston operating areas 74 in the diaphragm membrane 70 are sequentially driven and displaced up and down by the up and down reciprocating strokes of the four composite eccentric circular bodies 502.

  Thirdly, when the composite eccentric circular body 502 in the present invention moves in the upward stroke and the piston action area 74 is displaced upward, the action force F is applied to the corresponding annular positioning protrusion 76 of the diaphragm film 70. A portion between the outer raised peripheral edge 71 is pulled obliquely.

  Therefore, including the sloped upper ring 526 in the inverted frustoconical circular yoke 521 of the eccentric circular body mounting portion 500 eliminates the fragility of the diaphragm film 70 caused by the high frequency squeeze phenomenon (this destruction is usually 125, caused by a rounded shoulder 57 in the conventional tubular eccentric circular body shown by the two-dot chain line in FIG. 125) and also the recoil force of the diaphragm membrane 70 caused by the acting force F (shown in FIG. 126) Significantly reduce Fs.

  Furthermore, under the same acting force F, the recoil force Fs is inversely proportional to the contact area. The increased outer diameter of the inverted frustoconical yoke 521 increases the contact area between the sloped top ring 508 and the bottom side of the diaphragm membrane 70 (shown by ring A shown in FIG. 126), thereby All dispersion components of the recoil force Fs for the inverted frustoconical yoke 521 of the present invention are further reduced.

  The method of making this adaptive form of a four compression chamber diaphragm pump with multiple effects of the ninth exemplary embodiment of the present invention is as follows.

  First, the circular body attaching portion 511 and the eccentric circular body attaching portion 500 are combined to be manufactured as an integrated object.

  Second, the truncated cone yoke 521 is made independently as a separate entity.

  Finally, an integral body of the circular truncated cone yoke 521 and the circular body attaching portion 511 is assembled with the eccentric circular body attaching portion 500 to become an integrated entity, thereby forming the assembled eccentric circular body 502.

  Thereby, the invention of the composite eccentric circular body 502 not only meets the requirements of mass production, but also reduces the overall manufacturing cost.

  The eccentric circular body 502 of the frustoconical circular yoke 521 of the present invention provides at least one of the following benefits.

  1. By including the inverted frusto-conical circular yoke 521, the durability of the diaphragm film 70 for maintaining a high frequency pumping action is significantly improved.

  2. Since less current is wasted due to the high frequency squeeze phenomenon, the power consumption of the four compression chamber diaphragm pump is greatly reduced.

  3. Due to the reduction in power consumption, the working temperature of the four compression chamber diaphragm pump is greatly reduced.

  4). Undesirable bearing noise due to aging of the lubricating oil in the four compression chamber diaphragm pump, which is accelerated by the influence of temperature, is almost eliminated.

  5. The service life of the four-compression chamber diaphragm pump is further extended because all the dispersive components of the recoil force Fs for the inverted frustoconical circular yoke 521 of the present invention are reduced.

  6). Since the present invention is suitable for mass production, the manufacturing cost of the four compression chamber diaphragm pump is reduced.

  As described above, the present invention substantially reduces the vibration reduction effect of the four-compression-chamber diaphragm pump by using a newly-developed simple pump head body and diaphragm membrane without increasing the overall cost. To solve all the problems of vibration-induced noise and resonant vibrations that occur in conventional four-compression chamber diaphragm pumps. Furthermore, the simple sloped upper ring for the various cylindrical eccentric circular bodies of the present invention can double the useful life of the diaphragm membrane in a four-compression chamber diaphragm pump, which is useful industrial Has availability.
