Abstract

The valve provides an unrestricted flow through a chamber from a first opening to a second opening while the reverse flow is first adjusted to a fine extent so as to allow a gradual increase in flow until full throughput is reached. To this end a large primary closing member engages the first opening so as to be urged off its seat under the action of the fluid entering said opening whereas the opposite flow seats said primary closing member. For this opposite flow, a control member causes a secondary closing member constituted by a rod coaxial with the primary control member to recede out of a port formed in the primary member. When said rod has receded sufficiently and allowed a sufficient throughput, it draws along with it the primary closing member which leads to the desired full throughput in said opposite direction.

INVENTOR fihmm STAMPFL/ ATTORNEY APPARATUS FOR ADJUSTING A FLUID THROUGHPUT The present invention has for its object an apparatus adapted to ensure a fine adjustment of a fluid output, more particularly an adjustment of the throughput for one direction of flow while the flow in the opposite direction remains unrestricted.
ln control systems incorporating pneumatic jacks it is often of advantage to provide a possibility of adjustment for the jack pistons with a view to producing a high speed progression in one direction and a slower return movement. Several adjusting means are known which include a closing member the position of which may be adjusted by means of a screw for instance. Such known arrangements all have however the drawback of making a fine adjustment a difficult matter, since even a very small shifting of the closing member leads for a given cross section afforded to a considerable modification of the throughput.
The present invention has for its object elimination of said difficulty and it is directed to an apparatus for adjusting a fluid throughput, of the type including a chamber provided with two openings for the passage of the fluid, a first closing member adapted to slide axially within said chamber between a closing and an opening position while a second closing member is adapted to be shifted axially by a control member with reference to a port provided for the fine adjustment of the fluid throughput. Now according to the invention, the two closing members are coaxial and have different cross sections, the port provided for the fine adjustment of the fluid throughput being formed through the wall of the first closing member.
In the accompanying drawings illustrating diagrammatically an embodiment of the invention:
FIG. 1 is a longitudinal sectional view of said embodiment;
FIG. 2 is a graph illustrating the flow of fluid through the apparatus.
Said apparatus comprises as illustrated a body 1 enclosing a cylindrical chamber 2 provided with two ports 3 and 4. A bellshaped, first closing member 5 made of plastic material is slidingly carried inside said chamber so as to be capable of moving axially therein towards and away from the opening 3. The upper section 6 of the closing member 5 is adapted to engage fluidtightly a seat formed by the shoulder 7 at the entrance of the opening 3 when the closing member is in its operative closing position illustrated in FIG. 1. The skirt of the closing member 5 is providedwith longitudinal slots such as 8 which afford a permanent communication between the inside of the closing member 5 and the lateral opening 4 of the chamber 2 whatever may be the axial position of said closing member inside the latter. At its upper end the closing member 5 shows a port 9 through which a fine adjustment of the throughput may be obtained and the part played by which will be disclosed hereinafter with further detail. Said port 9 affords a communication between the opening 3 of the chamber 2 and the inside of the closing member 5 and therefore between said opening 3 and the lateral opening 4 of said chamber.
At its end facing away from the opening 3 and coaxially therewith, the body 1 is tapped as shown at 10 so as to be engaged by the threads 11 on one end of a cylindrical section 13 which is disposed with a slight friction fit inside the chamber 2. Said cylindrical section 13 is provided on its outer surface with an annular groove 14 inside which is fitted a fluidtight toreshaped packing 15. A rod 16 coaxially rigid with the cylindrical section 13 may engage, with a slight amount of friction, the port 9 in the closing member 5 to thus provide a second closing member.
The cylindrical section 13 further includes a tubular extension 17 at its end facing the closing member, said extension being coaxial with the rod 16. The outer end of said tubular extension is provided with an outer shoulder 18 adapted to engage an inner flange 19 at the corresponding end of the closing member 5. The latter is rigid with an inner central tubular extension 12 adapted to guide a coil spring 20 fitted in a compressed condition between the upper inner surface ofthe closing member 5 and the bottom of the tubular extension 17 of the screw 11.
The operation of the apparatus is as follows:
When in the position illustrated, the closing member 5 is held in contact with the seat 7 surrounding the opening 3 by the compressed spring 20.
lfcompressed fluid is fed through the opening 3, its pressure urges the first closing member 5 against the comparatively weak pressure exerted by the spring 20 so that the fluid can flow freely from the input opening 3 towards the output opening 4. it should be noted that the rod 16 does not oppose the shifting of the closing member 5 towards its opening position since it can engage with a slight amount of friction the port 9 in the upper end of the closing member 5.
In the case of a reversal in the direction of flow of the fluid, that is if the compressed fluid enters through the opening 4, said fluid flows into the inside of the skirt of the closing member 5 through the slots 8. Under the action of the pressure exerted against its inner wall, the closing member 5 is urged against its seat 7 surrounding the opening 3 so that a fluidtight contact is obtained between the upper section 6 of the closing member 5 and the seat 7.
If the rod l6 occupies the position illustrated in FIG. I. the fluid may escape from the inside of the closing member 5 towards the opening 3 through said port 9. Upon screwing of the screw 11, the latter is caused to progress within the chamber 2 so as to gradually reduce the cross section afforded for the passage of the fluid through the port 9, the flow of fluid being arrested when the rod 16 closes completely the port 9. At such a moment, the passage of fluid out of the opening 4 towards the opening 3 is completely cutoff. The graph of FIG. 2 illustrates the variations of the fluid throughput through the free cross section in the direction from B towards A that is from the opening 4 towards the opening 3, said graph carrying in ordinates the throughput Q and in abscissae the shifting C of the screw 11, the graph being drawn. for an unvarying drop in pressure in the adjusting apparatus.
If the screw 11 is unscrewed, the rod 16 gradually uncovers the port 9. Since the cross section of said port 9 is very small with reference to the cross section of the opening 3, it is obvious that the axial shifting of the rod 16 with reference to the port 9 allows a very fine adjustment of the throughput of fluid flowing from the opening 4 towards the opening 3, this being illustrated in FIG. 2 by the section a of the curve for which section a shifting a of the screw 11 carrying along with it the rod 16 is proportional to the throughput Q.
When the rod 16 has moved sufficiently far from the opening port 9 so as to release entirely the cross section of said port 9, the shoulder 18 on the tubular extension 17 of the screw It draws along with it the closing member 5 by engaging the inner flange 19. Consequently, any further rotary movement of the screw 11 in the same direction results in a gradual shifting of the closing member 5 away from the shoulder 7 surrounding the opening 3. The increase in fluid throughput for each fraction of a revolution of the screw 11 is then much larger than when the throughput is adjusted solely by the rod 16 cooperating with the port 9 so as to ensure a fine adjustment of said throughput. This is shown on the graph of PK]. 2 by a sudden increase in the throughput as illustrated by the section b of the curve for a shifting b of the screw 11.
