The present invention concerns an improved distributing valve. 1
Different types of distributing valves known up to the present time present numerous inconveniences against which there can be cited especially: rapid wear and deterioration of the joints of cylindricalslide valves due to i manufacture and, in consequence, less arduous; advantages such as great facility of control, perfect functioning, solidity and an exceptional resistance to wear etc.
According to the present invention an improved distribution system comprises a valve having a slider longitudinally displaceable in a cylinder provided with a plurality of orifices, such as admission, working and exhaust, the slider having mounted thereon one or more face flanges contacting the bore of the cylinder in front of the orifices. The slider may be'provided with two bearings, adapted to slide in the cylinder, separated by a bearing of smaller section comprising one or more grooves for housing one or several face flanges which are preferably madein hard plastics material, the number of face flanges depending upon the number of ways which the valve is to control. Theoperative face. of the or o I each face flange may be applied exactly against the bore of the cylinder and, preferably, the-or each face flange is in the form of a cylindrical sectorwhilst the. bore of the cylinder may be In this way thereis obtained a distributing. device in the form of a valve having a face flange which permits the obtaining of an excellent seal and an automatic taking up of the play due to possible wear of the face flange and of the cylinder. The stops of the face flange can pass 3,227,180 Patented Jan. 4, 1966 bore in the block by two lateral identical cheeks closing {the cylinder. These cheeks may comprise admission and exhaust orifices for the control fluid of the slider and,
also, the joints on which one or other end of the slider come into-abutment, thus closing one or other of the The two cheeks may be made symmetrical in such a manner as to permit fixing in the block and access to the feed control orifices of the slider and on all preferred lateral faces of the blo'ck'.
- The block and cheek assembly may be fixed on a base-plate with the interposition of a coupling connecting plate for the corresponding orifices of the assembly and the base-plate, the coupling plate being made preferably with branch orifices for conduits, respectively coincident with the orifices opening on its face normally in contact with the coupling plate. This coupling plate which may easily be made in moulded plastics material, assures an excellent seal between the block and cheek assembly and the base-plate on which the various branch connections of the valve can be effected.
The invention will now be described further, by way of examplerwith reference to the accompanying drawings, in which:
FIG. 1 is a longitudinal section of the distributing valve constructed in accordance with the invention the slider being in one end position;
FIG. 2 is a cross-section of the valve shown in FIG. 1;
FIG. 3 is a perspective view showing the several constituent parts of the valve shown in'FIGS. 1 and 2 in the course of assembly;
'FIG.'4 is a partial longitudinal section of the valve shown in FIG. 1 in the end position of the slider opposite to that shown inFIG. l;
FIG. 5 is a perspective view showing the assembly of the different constituent parts of the block and base-plate assembly of the valve; and
exhaust, orifices 8 and 9 of the cylinder 2. The slider 1 comprises two end bearings 15, 16 sliding freely inthe cylinder 2 and an intermediate bearing 17, of smaller -diameter,.permitting the flow of fluid from the orifice 5 to in front of the orifices of the cylinder without risk of becoming hooked or of deteriorating, the face flange being made in a relatively hard material, contrary, for example, to the supple joints of the cylindrical slide valves of known type. i
In another embodiment of distributing device, the or 5 each face flange may be mounted on supports engaging in appropriateihousings in the slider. g l
,The distributing assembly constituted by the cylinder,
the slider and the face flanges maybe fixed in a block,
after the introduction of the assembly in an appropriate the working orifices 6 and 7. Two oppositely disposed grooves 19 and 20, smaller than the bearing 17, are made therein so that one of them comes up to the flank of the bearing 15 and the other up to the flank of the bearing 16. and a bore 25, perpendicular to the two slots 19 and 20, is made in the middle of the slider 1.
The two identical faceflanges 3 are constituted by a .also, each face flange 3 is provided with a cylindrical off-centrefoot 32.
The two face flanges 3 are mounted on the slider 1, by the introduction of their foot 32 in the bore 25 and their body 28 in the grooves 19 and 20, symmetrically opposite with respect to the axis of the slider 1 and to the bore 25. The slider 1 is provided with face flanges 3, and then introduced into the bore of the cylinder 2 in such a manner that the face flanges coincide, one with the orifices 6 and 8 and the other, with the orifices 7 and 9 of the cylinder 2. Fixing against rotation of the slider 1 is elfected by the engagement in an end 40 of a fixing screw 41 of the cylinder 2 on the block 45 in an appropriate longitudinal slot 42 of the slider 1.
In one end position of the slider 1 shown in FIG. 1, the two working and exhaust orifices 6 and 8 are interconnected by a cut-out 30 of the corresponding face flange 3, the admission orifice and the working orifice 7 are connected by a flow of fluid between the intermediate bearing 17 and the bore of the cylinder 2 and, finally, the exhaust orifice 9 is isolated.
In another end position of the slider shown in FIG. 4, the two working and exhaust orifices 7 and 9 are connected by the cut-out 30 of the corresponding face flange 3, the admission orifice 5 and the working orifice 6 are connected by a flow of fluid between the bearing 17 and the bore of the cylinder 2 and, finally, the exhaust orifice 8 is isolated.
The two face flanges 3 are applied against the bore of the cylinder 2 under the effect of pressure fluid introduced into the bore of the slider 1 by the admission orifice 5; the fluid tends to push the two face flanges outwardly apart, the pressure fluid acting against the faces of the ends of the feet 32, after passage in a transverse aperture 48 of the slider 1, and against the faces opposite to the operative faces 29 of the face flanges 3. The face flanges 3 will always be applied energetically against the bore of the cylinder 2, the counter-pressure which can be exerted on the base of the cut-outs 30 being always less than the pressure of application of the face flanges 3 against the wall of the cylinder 2, not only when the cut-out 30 is above the single exhaust orifice 9 or 8, but also when the cut-out connects the working orifices 6 or 7 respectively to the exhaust orifices 8 or 9.
Due to the fact of its shape, the operative face of the face flange permits the obtaining of an excellent seal and an automatic take-up of the wear. Also, the face flanges 3, being made preferably in hard plastics material, not engaging in the orifices 6, 7, 8 and 9, after their passage, cannot be deteriorated thereby, contrary to the known supple joints of valves having cylindrical slides. The application of the face flanges 3 against the bore of the cylinder 2 is always balanced and does not create jamming of the sliding of the slider 1.
Always in FIGS. 1 and 2, and as is more particularly shown in FIG. 5 the distributing assembly, constituted by the slider 1, the cylinder 2 and the face flanges 3, is housed in a block of a size sensibly equal to the length of the cylinder 2 and fixed thus by two identical cheeks 55 by the use of a screw 56. The seal is made by two circular joints 57 housed in appropriate grooves 58 of the cheeks 55.
Each check 55 is a prism having a base in the form of a T, the face corresponding to the upper stop of the T abutting against the block 45; an orifice 60, made in the centre of the abutting face of the check 55, coincides with the arrival orifice 61 opening perpendicularly on one of the faces of the T of the cheek 55. Each cheek 55 comprises a hole 64 for the passage of a fixing screw 65 (FIG. 1), the hole 64 being provided with two counterbores 66 for housing the head of the screw 65 permitting the obtaining of reversibility and interchangeability of the cheeks 55 and, also, to permit the fixing of the block and cheek assembly 45, 55 and the disposition of the orifices 61 on either one of the lateral faces of the block 45.
The mounting of a valve on a machine or similar can be facilitated by the distribution of the block and cheek 4. assembly 45, 55 on a base-plate such as 70 comprising, on both sides of the base of the cheeks 55 constituted by a T, holes 71 for the passage of screws, gudgeons or similar beneficial means of fixing as well as an excellent accessibility.
As shown in FIGS. 2 and 5 the block and cheek assembly 45, 55 is fixed on the base-plate 70 with interposition of a plate 80, preferably in moulded plastics material permitting the obtaining of an excellent seal for the assembly. The plate comprises, on its support face against the block and cheek assembly 45, 55, holes such as 81, 82 and 83, respectively corresponding to the control orifices 61 of the cheeks 55, to the admission orifice 5 of the block 45 and to the orifices 85 of the block 45 opening into the working and exhaust orifices 6, 7, 8 and 9. The holes 81, 82 and 83 opening either on the other face of the plate 80, such as the holes 81, 82, or in the appropriate throats 88 of the other face of the plate 80 such as the holes 83 (FIG. 2). The throats 88 permit the connection of the holes, such as 83, to the corresponding holes 89 of the base-plate 70; the holes 89 are connected to the branch bores 90 by means of holes 91 perpendicular to the holes 89; the holes, such as 81 and 82, are axially coincident with the corresponding holes 89 of the baseplate 70. This base-plate 70 can be made in a particularly economic manner, all the holes being made perpendicular to its various faces; moveover, on the plate 80, there can easily be made throats 88 of the holes of the base-plate '70 connecting with the orifices of the block and cheek assembly 45, 55 in dispositions corresponding to the preferred couplings.
In an embodiment (not shown) which permits the connection of the corresponding orifices of the block and cheek assembly 45, 55 and of the base-plate 70 in accordance with any relative position, the plate (such as 80 of FIGS. 2 and 5) could comprise throats (such as 88) on its two faces authorizing, for example, the superposition of two different fluid conduits, or even one of the conduits could be constituted by means of a hole opening into two throats disposed respectively on one and the other of the two faces of the plate which, as the plate 80 above, could be made simply and economically by moulding of plastics material.
In the embodiment shown in FIG. 6, the slide 100, provided, as the slider 1 of FIGS. 1 to 4, with two end bearings 101 separated by a reduced diameter bearing 102, comprises two opposite grooves 104 and 105, made along the whole length of the bearing 102, and a bore 106 perpendicular to the grooves, in the middle of the slide 100. The cylinder 110 lies sensibly similar to the cylinder 2 of the preceding figures. The two face flanges 112 only differ from the face flanges 3 of FIGS. 1, 2, 3 and 4 in that they do not have any feet (32 of the face flanges 3) and in that they are provided on one of their ends with a flange 113. This embodiment comprises two supports 115 for the face flanges 112 constituted by a plate 116 comprising two longitudinal flanges 117 and a foot 118. The face flanges 112 are mounted between the fiang'es 117 of the supports 115 which are disposed in the grooves 104 and 105; the length of the face flanges 112, of the supports 115 and of the grooves 104 and 105 being similar, the face flanges 112 are longitudinally fixed and, also, transversely fixed by the flanges 117 of the supports 115. It is to be noted that the two face flanges 112 are mounted back to back, the flanges 113 being found respectively on one side and on the other of the slide 100. The assembly of the slide 100, face flanges 112 and supports 115 thus mounted is then introduced into the cylinder 110 and fixed against rotation by a screw 120; the functioning of the valve thus made will remain identical with that of the valve shown in FIGS. 1, 2, 3, and 4.
The flow of control fluid between the admission orifice 5 and the working orifice 6 or 7, is effected around the bearing 102 and by the clearances of the flanges 117 of the supports 115 and 126 of the flanges 113 of the face flanges 112.
The distributing device could be applied to any valve presenting any number of Ways, the different constituent parts of the valve could be made in any material and/ or combination of materials, presenting any aspect, subjected to any physical or chemical treatment etc. in view, for example, of their protection against wear or corrosion of the valve could be destined to any purpose and/or be controlled by any means, pneumatic, hydraulic, etc.
