Description

[Detailed description of the invention] Pilot-controlled two-stage regulator Background of the invention 1. Field of invention The present invention relates to a regulator for underwater breathing apparatus, and in particular to a regulator for controlling air pressure amplification. This invention relates to a two-stage gap and -bar adjuster using B and G valves.

2 Description of conventional technology In a typical self-contained underwater breathing apparatus, air or other breathing gases are It is supplied to the diaper from the high pressure tank via a two-stage regulator. @-R114 section is provided It is attached to the supply tank and reduces the air pressure to about 140 psi, which is higher than the outside pressure. It works like this. Generally, the tank and first stage regulator are supported on the back of the dialer. Ru.

A conduit or hose supplies reduced pressure air to the second stage regulator at the intake of the dialer.

This second stage opens to supply breathable gas in response to the inhalation effect of the diaper. Such a desired valve′! 1 has paulownia. Preparation for exhausting gas through the inlet It will be done.

The use of pneumatic amplification in a two-stage adjustable ski bar achieves extremely low suction effects. It is desirable to do so. One such regulator was released on February 28, 1978. Patented FI & device pyro, valve operation regulator, 40th percent fraud in the United States No. 76041.

For convenience, but not necessarily, this regulator is based on the breathing system patented April 3, 1979 A diaphragm device for a regulator that resembles a device, patented in United States Patent No. 414717 It may be used with a diaphragm having a variable effective sensing inner pole of the type shown in No. 6. Ru. This diaphragm and regulator is advantageously incorporated in the June 14, 1977 patent. A must for breathing equipment! This is a linkage for a regulator that is patented in the United States Patent No. 402912. They are connected by a mechanism of the type shown in No. 0.

It has been found that type regulators using these techniques can achieve very low inhalation effects. There is. That is, the diaphragm can normally be inhaled underwater, and the regulator can control the appropriate amount of breathable gas. Unlike regulators without pneumatic amplification, which work to ensure flow, diaphragm Excessive inhalation force (i.e., usually deeper “breaths”) to ensure the opening of the pulp. There is no need to use

However, it is understood that the Ig & structure described in the above patent requires improvement. , one object of the present invention is therefore to facilitate such improvements.

Best mode for carrying out the invention The following is a detailed review of what is currently considered the best state of implementation of the present invention. It will be done. This description is intended in a non-limiting sense, but only to illustrate the general principles of the invention. The best scope of the invention is set out in the separate claims. .

The scuba pilot regulator 10 of the present invention has an appearance shown in FIG. Cases made of plastic or glue such as Delrin with high impact resistance. s]l. As described below (Figure 6), the regulator pulp assembly 2 2. To 40 is a case that is covered with a cap 12 and a character pretty collar ring 13. It is possible to insert a torishi zushikai through the edge of the slot 11. Regular tank and The air acid from the first stage regulator passes through the breathing device 14 and the inlet pipe 15. A regulator 10 is supplied. The inlet pipe 15 is an inlet of rubber or glass tee. 17 enters the case IIK in close proximity to the regulator outlet 16 where the mounting 6 is mounted.

This arrangement, in which the inlet tube 15 is located in close proximity to the inlet 17, makes it easier for the user to This reduces the torque load on the user's teeth when the head rotates.

As shown in Figures 2 and 3, the air flow to the user is controlled by the pyro, valve machine Kiri 1 8.

Regarding the general operation of the i4 valve mechanism 18, please refer to U.S. Patent No. No. 4.076,041.

This pulp mechanism 18 has a housing as shown in FIGS. 2, 3, 6, and 7. It is contained in the ring assembly section 20.

This housing assembly part 20ti includes a housing 21 having an excessive cup shape. , this cup-shaped housing has a cylindrical skirt 21 & a closed end 21b and an interior It has a cylindrical portion 21e. The artificial pipe 15 passes through the leak-proof opening 21d, Extending into the skirt 21a, there is a Nichido type part 21eK, and it ends at the opening 21. There is. In this way, the inhaled air is sent to the exhalation chamber 22 with the cylindrical part 21e.

As described below, the end 21f of the cylindrical portion 21e controls the flow of air to the user. tapered to form an annular rim that acts as a valve seat for a poppet valve with It has been subjected.

/s23 (Figs. 2 and 3) is located inside the housing cylindrical part 21c. It includes a poppet 24 (FIGS. 4 and 5) containing a section. This/-e .

) fls23Fi artificial pipe 15 or artificial 15 main air flow IIIKI It has an O-ring 25 that works together with a valve seat 21f to do so. Valve seat 21f and 0ri The ring 25 thus constitutes the main air flow side a element of the poppet valve 26. .

In the case of the neutral mode shown in Fig. 3, the 26 poppet valves and the valve seat 21fKli are in contact with each other. It is closed with an O-ring 25. In this state, there is no flow from the inlet pipe 15 to the user. Airflow is obstructed. In the personal mode shown in FIG. 2, the poppet section 23 is Ring 25f: is moving towards the blade of the cap 12 so as to separate it from the valve seat 21f. this When the valve 26 opens as shown in FIG. 2 to the outer wall of the housing 21) defined by the outer wall of 21 m It is supplied to the annular chamber 27. The m-shaped chamber 27 is surrounded by the cap 12 (FIG. 2). ing. This means that only the outlet from the annular chamber 27 is connected to the closed end 21b of the housing 21. This is to form an opening 28 (FIGS. 2 and 7).

As shown in FIG. 2, the entire housing closed end 21b including the opening 28 is 30 It is conveniently made of silicone, silicone, or such materials. Easy-to-bend disk It is marked with a sticker 29. This seal 29 is held in place by a rigid disc 31. has been done. The portion 31m#'i of the disk 31 facing the opening 28 in FIG. It is bent away from the housing 21 as shown in FIGS. 6 and 7. . The inlet air flows from the open extension 26 through the annular chamber 27 and opening 28 so that the As shown in Figure 2, a portion of the disc deflector is located away from the housing end 21b. Press the flap of seal 29 so that it contacts 311. Opening like this The air flowing from 28 is passed through the seal 29 and the disk deflector part 31m. is deflected to the force of outlet 16 and inlet]7. Inhalation effect or R-Nturi effect To achieve this, adjust the angle of the disc deflector part 31m to a flow rate of 5. Controlled by Neutral mode (no air flowing through the opening 28) In FIG. 3), the seal 29 covers the opening 28.

This prevents water from flowing back into the annular chamber 27 and the poppet section 23. difference In addition, when regulator 10 is not used, seal 29 prevents sand and other foreign objects from entering the pope. This prevents the cut portion 23・\ from getting mixed in.

The parts 23 and 23 are improved type ports 24 having the shapes shown in FIGS. 4 and 5. has. The poppet has an outer diameter slightly smaller than the inner diameter of the cylindrical portion 21c of the housing. It has a cylindrical portion 241 with a diameter. This cylindrical portion 24m defines the inner wall of the exhalation chamber 22. Ru. /-ey) One end 24b of 24 has an outer diameter corresponding to the inner diameter of the cylindrical portion 21e of the housing. It has a #I cutout to hold the O-ring 34. in this way The end 24b forms one end of the exhalation chamber 22.

/”t) 24 is an annular flange whose outer diameter corresponds to the inner diameter of the cylindrical portion 21e. It has a di or annular shape, di 24e.

/It 24 moves between the closed position shown in FIG. 3 and the open position shown in FIG. 2 in the cylindrical portion 21e. Can move axially.

During such movement, the flange 24e remains in continuous contact with the cylindrical portion 21eK. be. This is Pobe.

The shaft 24 is coaxial and maintains a straight line within the cylindrical portion 21e regardless of its axial position. ensure that This will cause the flange 24eFi pope and 24 to tilt. is prevented.

A relatively large hole 24d crosses the poppet 24 in a direction perpendicular to its axial direction. It is extending. The axis of the hole 24d conveniently coincides with the center of the face of the flange 24e. has been done. This hole 24d accomplishes two functions. First of all, poppet In the exhalation chamber 22t and the cylindrical bike, an air flow path is provided from the exhalation chamber 22t to the valve chamber 35. ing. Second, a flow path passing through the flange 24c itself is created in the exhalation chamber 22. There is. As shown in FIG. 5, as a result of the hole 24d, the flange 24g itself is completely Rather, the flange 24e does not form a perfect circle. ) has a part 24, through which air flows past the flange 24e. can be In this way, when the pulp 26 is open (Fig. 2), the air Flows from the tube 15 in the exhalation chamber 22 through the notch 24 and through the valve 26. Ru.

At the pulp 26, hold it properly by the top cap 36. has been done. Against the end 24f of this I pet cat f36d, fpe, to24. It is decorated with a mountain. The cap 36 has a flared annular flange 36m. There is a groove 36b on the front side of the plate that receives the QIJ ring 25.

This groove 36b is located above the part of the O-ring 25 that faces the valve seat 21f. Wi-shaped 1 hook "36" protruding from the top (when shown in cross section in Figure 2 or 31) The groove 36b is cut slightly inward to form a groove 36b. With this, 0 Ring 25 and cap 36? Appropriately forcefully hold or hold between the bed portions 24g. The inlay is done. These two parts surround approximately i around the O-ring 25. shi, so that only the 8th part corresponding to the annular contact line of the valve seat 21f is 11mm. is set up. There is no possibility that the O-ring will shift position during the adjustment operation. stomach.

The portion 23 is biased toward the housing by a spring 37. At the bottom, one end of the spring, pope, toca, surround f36, flange 36 I'm on my way to m. The other end of the spring 37 usually has a leg 38m with a U-shaped cross section. The retainer 38 is in contact with the retainer 38. Both wa#'i with legs 38m, with retaining ring 39 Therefore, it is attached to the housing cylindrical portion 21c.

1i38 holding the spring of retainer 38 is conveniently disk-shaped. It is shaped like this. This spring retainer provides a complete pulp housing assembly. 20 and Bope,) 51123 was removed, f12 and cap ring 13 were removed. One 22 to him, and 4o (Figure 6) is removed from case 11. This removal This is further facilitated by the slot l1m in the case 11.

The inlet pipe 15 has a melody 2. The housing assembly part is located inside the torque l1m. Slot when 20 is missed.

Another improvement of the present invention is the shape of the pyro and top pin 41 and the shape of the pilot valve 4. Concerning the other points of 2.

The pulp itself flows from the annular valve seat 24b formed in the four pet 24 at the front end of the chamber 35. take. The poppet 24 has a capped end of the poppet in almost all directions with a cap of °/36. Gara? It has an inner shaft hole 24j that extends to the pet end 24b. Diameter is hole 2 The second pivot hole 24k [, the chamber 3 defined by the hole 24k] is smaller than the diameter of the hole 4j. 5 through end 24b. The inner edge of hole 24 is not flat; Rather, when viewed in cross section (Figs. 2 and 3), it forms a valve seat 24h with an overall shape. It has a 'hook' shape.

Δiro, spread through Tohin 41#11M35, and tpe, tokya, pu3 It has a cutout 41m extending into the central opening of No.6. In this extraction part, the pin The ring 41 is sealed by an O ring 43 that is stopped inside the fpe, toca, and pu 36. It is. The other end 41b of the pin 41 passes through the hole 24k and also connects to the diaslug as described below. A portion within the lumen coupling projects through the orifice member 44 in contact with the hole 50.

P1. A peak between parts 41m and 41b of the valve 41 serves as a closing part for the pilot valve 42. There is an existing groove 41c that receives a working O-ring 45. This 0 ring 45ii, pin It is held in place by a ring 46 which covers part of the ring 41. This phosphorus The ring 46 has an annular lip that covers a part of the O-ring 45, and the periphery thereof. The grooves 41e are directed outward in a radial manner. In this way, 0 ring 45L, 24 h　K Only a relatively small part around it is in contact with the valve seat 24h. In the calculated state, it is firmly held by the pin 41 and ring 46.

Poppet hole 24kFi, pyro, has essentially the same diameter as the diameter of the valve seat 24h ing. The pin end 4.1b allows inlet air to flow into the exhalation chamber 2 when the pilot valve 42 opens. 2, through the poppet hole 24d and the chamber 35, and between the O-ring 46 and the valve seat 24h. It passes through the gap between the hole 24 and the bottle end 41bO, and then the poppet 2 4 and into the control chamber 49 between the orifice member 44. It is slightly smaller than the diameter of 4. The resulting pressure in chamber 49 is Push pet 24 to the right. This situation is clearly shown in Figures 2 and 3. This opens the poppet valve 26.

The air in the chamber 49 flows through the central hole of the member 44 or the air between the oriice 44m and the pin $41b. It leaks through the cracks. As a result, the pressure exceeded the orifice 44m, but the main poppet It will indicate the control pressure to open the valve.

According to the present invention, the diameter of the orifice 44m is approximately the same as the diameter of the hole 24. The inner pole of the annular opening between the orifice 44m and the pin end 41b is connected to the pilot valve 42. The valve seat area and the area are the same. As a result, compressed artificial air is present in chamber 49. At the same time as the pulp closure ring 46, right @1 (as shown in FIGS. 2 and 3) and the pressure acting on the left side toward Orice 44m becomes equal 0. As a result, the control room The pressure within 49 will remain balanced.

This means that the valve seat and door orifice have a smaller diameter than the valve seat. In contrast to the design shown in US Pat. No. 4,076,041, .

Because of this difference, the annular orifice area surrounding the pin is significantly larger than the valve seat area. It was small. A pressure imbalance occurs in the control chamber, causing air to escape from the control chamber through the orifice. is leaking out, so when you try to shut it off, Pyro.

There was a tendency to leave the valve open. This imbalance is eliminated by the present invention. , thereby eliminating a potential source of regulator 1° instability.

Referring to FIGS. 2 and 6, the housing assembly s2° is A guide culm 2 coaxially extends from a cylindrical portion 21h protruding forward from the ring 21. I have 1g’i. The cylindrical portion 21h is connected to the lever 52 and the linkage arm 53. A pair of rigid balls are connected to each other from the linkage between the pilot valve 42 and the diaphragm 55. 50 and 51 included. The basic operation of this linkage is It is disclosed in the invention of Grant No. 4029120.

Linkage arm 53 is made of Delrin or other rigid plastic material. This is usually the case, and its shape is as shown in FIG. Lever 52 is arm 5 The opening 21j is connected to one end 53m of the cylindrical part 2 and the cylindrical part 2]hK. through and extending into the gap between balls 50 and 51. Near the center of arm 53b The ring 53c formed is loose! ll! Teoshi, $21. guided by Do something. Kuchi, Kuna, and To 54 pass the end of $21g to help stop arm 53. ing. The disk-shaped end 53d of the arm 53 holds the diaphragm 55 in the center. The center 55m of the support is an arm 53 coaxially aligned with the guide ring 53e. 9 is attached on top of the protrusion 53 with miso cut around it extending from the periphery. There is an opening with a protrusion inside.

The diaphragm 55 is located within the widened end 11a'L11b of the safety case 11. The internal conical platform is an integral part of the case 11. It is attached to. Diaphragm 55 and conical plastic, toform lie is a diaphragm part of the type shown in the invention of US Patent No. 4147176. Collaborative.

The effective sensing area of the diaphragm is uniformly reduced in proportion to the diaphragm displacement. Ru.

In use, during inhalation the pressure at the moderator outlet 16 is reduced and the dial is turned off as shown in FIG. A similar displacement of the flamm 55 to the right occurs. This displacement is 1j cage arm 5 3 to the right, thereby moving the ball 50. 52, thereby moving the bin 41 to the right. Is that so? Pyro, Toben 42 The pressure of this air in turn opens the poppet valve 26, allowing inlet air to flow into the control room. , the air is supplied to the user via the opening 28 and the outlet 16. Deflector-m3 1 m changes the flow of air from the opening 28 toward the outlet 16, and the diaphragm 5 Prevent air from flowing directly towards 5. At the same time, the inch lily effect is achieved. stability is increased.

The adjustment of the linkage section extends through the cylindrical section 21h and is adjusted relative to the ball 51. Facilitated by a screw 56 with a central recess 56ai serving as a fixing stop.

The inward and outward movement of the screw 56 changes the stationary point of the gill 51. This adjustment Since the resting point of the ball 51 is determined, the ball 50 is at its highest point at the diamond 72m 55. It starts moving immediately when it is first displaced. In the embodiment shown in FIG. The wI4 fair end faces the regulator outlet 16. This screws through outlet 16. It facilitates adjustment due to my intrusion. However, it prevents the user from The adjustment screw 56 is mounted 9 toward the inner wall of the housing 11 in order to . In that case, the unit 40 is removed from the casing 11 (as shown in FIG. 6). It can be adjusted when

This diaphragm 55 also functions as a vent valve for the regulator. For this purpose, da The exit rim 55bii of the iaphragm 55 moves away from the foam IIs. I am free to do so. Thus, during breathing, the exhaled air flows to the regulator outlet 16. press the edge 55b of the diaphragm to separate it from the Zorato foam lle. , and through the opening 11e (FIGS. 1a and 2) at the front end of the case 11. Run away.

The cover 60, which is held within the large opening 11f by a ring 61, It is located at the id.

This cover 60 is made of a freely bendable material such as neoprene. The central exhaust button 62 is supported. When this button is pressed, it bends freely. The center part 60m of the cover 60 is disposed in the center part 60m of the cover 60 by displacing the linkage arm 53 and attaching the regulator pulse. t-Push against the protrusion 53 so that it opens. Exhaust is carried out there. Fig. 9 and in the alternative embodiment of FIG. There is a hole in the flam part 65 because the exhaust pressure is very low and the inside of the regulator - Prevents water from leaking into the mouth.

This 4'4 has a solid conical platform 11c (the embodiment shown in Fig. 2) for 30 shots. An easy-to-flex internal diaphragm made of soft, flexible rubber such as silicone. 66 (FIG. 9).

This diaphragm 66 is fitted within the flange molding of the regulator plastic housing 11. It is surrounded by a portion 66m of an annular retainer of generally U-shaped cross section which engages the section 11g. There is a large central opening.

The outer diaphragm 67 is also light and flexible, quickly returning to its original shape after being deformed. If the outer diaphragm 67 is made of a material such as silicone rubber, The general shape corresponds to that of the diaphragm 55 in FIG. It is attached to.

The inner and outer diaphragms 66 and 67 have equal diameters, with a central surface 68 and a are in contact with each other. Each diaphragm 66 and 67 has a bead on its outer periphery. There are 66b and 67b. Generally the two diaphragms are shown in tig9 diagram. A hard plastic fastener 69 with a U-shaped cross-section, approximately half or more of its circumference. It's all tightened up. The center of the fastener is located between the housing part tth( The regulator is located close to the bottom of the regulator (FIG. 1a). Tightening the diaphragm The hidden parts 66e and 67efip are located near the head of the articulator 10m. .

Therefore, during expiration, according to the positions shown in the images at 66', 67/ in Figure @9, It extends away from both portions 66c and 67c of the exhaust gas diaphragm. exhaled air The embodiment of FIG. Lower expiratory pressures than those associated with this may be required.

During the intake, the pressure reduced at the intake outlet 16 is between the central plane 68 and the linkage arm. With a concomitant movement to the right of the fifth leg (as shown in Figure 9), they compress toward each other. It acts on both the inner and outer diamond 7 rams 66 and 67.

Since the two diaphragms 66 and 67 are in contact with each other, a suitable effective sensing area is obtained. It will be done. However, unlike the configuration in FIG. 2, the outer diaphragm 67 is There's no need to envy its shape inside. This means that compared to the embodiment shown in FIG. This results in a reduction in the intake pressure required to move the cylinder arm 5J over a distance. .

In the case of the shape shown in Fig. 9, the water passing through the diaphragm part 65 flows into the regulator 10m Undesirable leakage of water is significantly reduced. This is the area around diaphragm 67. The fact that 1/2 or less is tightened against the inner diaphragm 66 and the tightening In areas 66e and 67e where the two rubber diaphragms are in contact with each other, This results from both the fact that a very good external seal is provided.

Yet another improvement is shown in Embodiment 10C of FIG. When not in use, there is a “date-” mark to prevent inadvertent actuation of the regulator. The difference is that there is a tan of 70. In cases where there is a possibility that such an abnormal operation may occur, In this case, there are two typical positions.

First, the two regulators in the second stage are installed in the same tank and regulator as the first stage, and in a separate It is used in a 1 octopus arrangement so that it can be attached and swung by a hose. Currently, this outfit However, it is normal for the damper to breathe through one of two two-stage regulators. It is used as a safety step. For those who remain, check the diameter itself (if it is a normal inhaler) (in case of a malfunction) or in case of an emergency useful for use. One situation that stands out is when a diaper is swimming on the surface with a snorkel. Sometimes it means removing the regulator from the mouth. Also in i, The inside of a regulator that is not in use becomes dirty with water. Since the dialer moves, the result is Fluctuations in the internal water pressure caused by the diaphragm 55 (Fig. 2) (Fig. 9) may occur. This means that the compressed air from the tank is desired. Raise the regulator to open due to incorrect flow. ``d@tame　” Gitan 70i, Attempt to eliminate activation of such regulators during inadvertent use.

For this purpose, the tongue 70 has a circular opening in the cap 12e. It is marked in 71. The inner surface of the opening 71 is grooved. The taper angle 10 is tapered from the central tip 71b of the opening 71 toward the inside of the regulator 10c. 6 has a tapered or conical surface 7] mt- to increase the diameter. 2nd taper 1ij 71c increases the radius from the mine 71b toward the outside of the regulator 10e. It extends for a long time.

One O-ring 72 is in contact with the opening 71 and in a groove 70 m around the circumference of the tongue 70. It is in. The inner surface of the butane 70 has a ``tun@'' button 70 shown in Fig. 11. When the cap 12e is in the closed position, the surrounding flap should sit opposite the inner shoulder 12m of the cap 12e. It has a lunge 70b. The miso 70 koshiki is placed in this position with the 0 ring 72. is positioned opposite to the outer tapered surface 71c.

A pin 73 protrudes inward from the center of the d.tan.1 button. child into the end 38b of the spring retainer 38, protruding through the opening @38d. There is.

The pin 73 is a pilot pin inserted through the opening 36d at the extraction part of the Ipe, Toca, and Pu 36. Facing 41 no Nuki @ 41 e. The length of pin 73 is -d@tune”. When 70 is in the inoperative position shown in FIG. 410 Leave enough space between the tongue and the pin end 41 to allow normal movement. Il can be selected as there is.

@dstmae” When yN tan 70 is linked, the user is too busy with mine 71 b’i and push the O-ring 72 to the left against the outer surface 70e of the f-tongue 70. this In the interlocking position, the pin 73 contacts the end 41 of the pin 41. Internal Qi/Mother-face 7 The pressure of the O-ring 72 against 11L is a force directed to the left, as shown in FIG. Create an element.

This is transmitted to pin 41 via pin 73t. Now, the regulator 10c is under the water. Ah, when it is outside the mouth of the diaper, the diaphragm 55 or diaphragm part 65 The pressure fluctuation of the water with respect to the inside of the "datune" is caused by the pin 41K It is still insufficient to exceed the force of 11t<.

Accidental failure of regulator 10e with undesirable airflow is prevented.

On the other hand, when the dialer puts the adjuster 10e in his mouth, he presses the "d@tt+ne" button. 70 automatically returns to the released position by the initial “deep breath”. Therefore, a sufficient pressure difference crosses the diaphragm 55 or the diaphragm portion 65, As shown in FIG. 11, move the pin 41 slightly to the right. This displacement is , open the pilot valve 42 slightly, and -detune'' the tongue 70 to the right. You need just enough to move the sword slightly.

This force need not be sufficient to move the O-ring 72't using the mine 71b. As soon as the first valve 42 opens slightly, the first pet valve 26 opens concomitantly. High-pressure inlet air is immediately supplied to the inner chamber 27. Press 0d. As a result of the increased pressure, the tongue 70 becomes unloaded. In this process, press the O-ring 72 past Mine 71b. . The 1lilJill device 10c then operates in its normal unattended state.

In this way, the ``d@twIB@'' button 70 is pressed before accidental use of the regulator. It can be easily linked to J70e with finger pressure. When using the regulator later @tun@” There is no need to untangle the butane by hand. For the dialer, place the regulator 10c in your mouth. , -d@tum・1 takes an initial strong breath to keep tongue 70 in the released position. Kotoda forest is necessary.

Conveniently, "d@tum・" is used to move the tongue from the interlocking position to the release position. The required travel distance is greater than the distance required for the exhaust to engage the tongue 62. child When the air source is cut off, as in Do not move the tongue from the engaged position to the released position.

1. However, when the air source is connected, pressing down on the exhaust button will cause the delta pilot valve 42 to move slightly. and the I-bet valve 26 is incidentally opened slightly. This means that det in the release position Make sure that enough artificial air enters chamber 27 so that the button is pressed down. The sea urchin “detua・” takes an initial strong breath to keep the tongue in the no-load position. Since use is alternative, the user simply presses the hot button 62.

Other characteristics or changes result from the second stage regulator according to the invention, e.g. And in the embodiment shown in FIG. Department. However, this book is not restrictive, but rather an alternative. , the diaphragm support disc-shaped end 53D is separated into separate parts as shown in FIG. ing. This portion 53D extends from the disk 53d' in the opposite direction from the hole 53/. It has a screw tip 53f'. From now on, 53 f'[, ring 53. away from e It is connected to a threaded ring 53g' formed at the end of the coaxial arm 5. . Such an arrangement facilitates adjustment of the rest point of the diaphragm 67.

In the embodiment of FIG. 11, the pin 73 is a plastic "data". It is shown to be a thin metal rod extending from the hole in button 70. alternative Therefore, -detaae- methane and the pin are formed as one body, and the pin is An accumulation hole or protrusion facing the internal joint chamber °27 but extending from the tongue surface 70d. It is made of plasti, which is a plastic part.

As mentioned above, when the regulator 10 is not in use, the seal 29ii is inserted. This prevents contamination of the poppet section 23. Cylindrical portion 21h through opening 21j (Figures 2 and 6) to prevent sand or other foreign matter from entering the A generally cylindrical sleeve 75 (Fig. 12), such as Rust, Ri or Resilane material. are placed around the outside of the cylindrical portion 21h.
