Definitions
- the present invention relates to a pressure fluid dispenser, including a manipulator for public works machinery. These distributors are used in particular to control different hydraulic functions such as the setting in motion of different receiving organs installed aboard these machines of public works.
- pressurized fluid dispensers of the type described in the preceding documents comprise:
- a body which comprises at least one cavity, one end of which opens on at least one upper face of the body,
- At least one pressure reducer which is mounted in the body, and which comprises a pusher which is reciprocally accommodated in said at least one body cavity in an axial direction, and a plunger which is mounted oscillating substantially in the same axial direction to provide the function of pressure reducer, and a control spring interposed between the plunger and the pusher, the balance of the plunger depending on the compression of the spring imposed by the depression of the pusher and the pressure of output regulation to be delivered to a downstream receiver member,
- a handle that is pivotally mounted relative to the body, facing the upper face of said body to control the reciprocating movement of said at least one pusher
- At least a first and a second seals which respectively provide hydraulic sealing internally and externally to the guide.
- the commonly encountered guides have grooves which are machined at their outer surface and their inner surface, and in which are intended to be inserted into them. joints. These grooves must be able to not hurt the joints during assembly. This therefore requires good control of machining and ribs obtained, generating high cost.
- a fluid dispenser of the aforementioned type is essentially characterized in that the guide comprises at least an upper guide portion and a lower guide portion which are attached to one another by interlocking , in that said upper and lower guide portions mutually delimit a housing facing the pusher, and in that the first seal is trapped in the housing.
- the fluid distributor has a guide made in two parts so that the assembly of the guide parts and seals is achieved by successive stacking.
- the risks of damaging the joints during assembly are very small.
- the dispenser comprises immobilization means which are attached to the body, at the upper face of said body, to allow locking in position at least the upper guide portion.
- the immobilizing means comprise a holding flange which is fixed on the upper face of the body.
- the upper and lower guide portions further delimit a housing facing the body and wherein the second seal is trapped.
- the upper guide portion is integral with the holding flange.
- the body is formed of two superimposed sections along a joint plane, an upper section in which the pusher is movably mounted and a lower section in which the major part of the plunger is mounted oscillating, the upper guide portion having come from matter with the upper section of the body.
- the holding flange and the upper part of the body are made of material together.
- the second seal is interposed between the upper and lower sections of the body, at their joint plane.
- At least the bottom guide portion is made of one of the materials selected from the plastic material, an injected alloy, a sintered material and a machined material.
- Figure 1 is a longitudinal sectional view of a fluid distributor according to the state of the art.
- FIG. 2 is a longitudinal sectional view of a fluid dispenser according to a first embodiment of the present invention.
- FIG. 3 is a longitudinal sectional view of the guide equipping the dispenser of FIG. 2.
- FIG. 4 and 5 are respectively views similar to those of Figure 2, a second embodiment and a third embodiment of a dispenser according to the present invention.
- FIG. 6 is a longitudinal sectional view of the upper section of the distributor body shown in FIG. 5.
- the pressurized fluid dispenser 1 shown in FIG. 1 is a distributor belonging to the state of the art.
- the fluid delivered by this dispenser is intended to supply a downstream receiving member not shown, under a pressure that is adapted to the use of this member.
- the fluid distributor 1 comprises a body 2 in which are mounted at least one and preferably several pressure reducers 3. Even if only two reducers are shown in FIG. Distributors are usually equipped with four identical pressure reducers. These reducers are generally parallel to each other and are oriented along the longitudinal axis X-X of the distributor 1.
- Each pressure reducer-3 comprises a plunger 5 which is mounted oscillating substantially in an axial direction parallel to the axis XX, and which moves in a cavity 6 formed in the body 2 of the distributor 1.
- This cavity 6 has a through end 8 at an upper face 7 of the body 2.
- the setting of the pressure reducer 3 is controlled by an operator by means of a handle 10 (partially shown in Figure 1).
- This handle 10 is pivotally mounted on the body 2, facing the upper face 7 of the body.
- a hinge 11, for example of the cardan type, makes it possible to secure the handle 10 to the body 2.
- this hinge is for example a spherical hinge, or even a pivot connection.
- the pressure reducer 3 comprises, in a manner known per se, a pusher 15 and a control spring 16.
- the control spring is interposed between the plunger 5 and the pusher 15 so that the equilibrium of the plunger 5 depends on the compression of the spring 16 imposed by the depression of the pusher 16 and the output control pressure to be delivered to the receiving member (not shown).
- the depression of the pusher 15 is controlled by the handle 10 so that it has a reciprocating movement inside the upper end 8 of the cavity 9.
- the guide in translation of the pusher 15 is provided by means of a guide 20 which takes the form of an immobilized one-piece sleeve at the open end 8 of the cavity 6 by means of a closure plate 21.
- a guide 20 which takes the form of an immobilized one-piece sleeve at the open end 8 of the cavity 6 by means of a closure plate 21.
- Two peripheral grooves 22 and 23 have been machined in the guide 20, respectively at the outer surface and the inner surface of this guide.
- an O-ring 24 has been immobilized to seal between the guide 20 and the body 2 while a lip seal 25 is immobilized in the groove 23 to seal between the pusher 15 and the guide 20.
- Such a distributor has the disadvantage of requiring very good machining of the outer and inner circumferential grooves of the guide 20 so that the O-ring 24 and the lip seal 25-are not damaged during their mounting on the guide. This requires good control of the ribs and the quality of the surface obtained, generating a high cost. On the contrary, according to the present invention, the sealing of the pusher guide is obtained in a simplified manner and therefore less expensive.
- the dispenser according to the present invention shown in Figures 2 to 6 comprises the same component parts as those described above with respect to the pressure regulating function. Identical component parts bear the same numerical references. Only the constituent parts of the pressure distributor according to the present invention will be described below which allow the pusher 15 to be guided.
- the pusher 15 moves back and forth inside a guide 30 which is immobilized at the open end 8 of the cavity 6 of the body 2, and which is made in two separate parts from each other.
- the guide 30 thus comprises an upper guide portion 31 and a lower guide portion 32 which are inserted into one another by interlocking. More particularly, the two parts 31 and 32 are interlocked along the axis XX so that one of the parts penetrates into the other by delimiting mutually internally a first housing 33 which opens internally, in the direction of the pusher 15. Similarly, the interpenetration of the upper part 31 with the lower part 32 of the guide 30 delimits externally a second housing 34, which is turned away from the first housing 33, opening towards the body 2.
- the upper portion 31 has a head 40 and a body 41, the inner diameter of the head 40 being reduced relative to that of the body 41.
- the lower portion 32 of the guide 30 has a foot 42 and a core 43, the outer diameter of the foot 42 being greater than that of the core 43.
- the shape of the core 43 and the shape of the body 41 are complementary so that the core 43 can be sleeved to the core 43. inside the body 41, their respective length being adapted to delimit the inner housing 33 and outer 34.
- the lower portion 31 and the upper portion 32 of the guide 30 are generally cylindrical in shape, whose inner diameter is substantially equal to the diameter of the pusher 15.
- the fluid distributor 1 further comprises immobilization means 45 which are attached to the body 2, at the upper face 7 of the body to lock in position the lower guide portion 32 bearing against a flange 46 belonging to the upper guide part 31.
- the immobilizing means 45 take for example the form of a holding flange fixed by screwing on the upper face 7 of this body 2.
- the stacking of the lower part 32 of the guide 30, the second seal 37, and the upper part 31 of the guide 30 is simply carried out. previously positioned the first seal 36 within the shoulder of this upper part. The assembly is then immobilized by means of the flange 45 inside the cavity 6.
- the guide according to the present invention is thus obtained without risk of damaging the two seals, and minimizing the cost of machining.
- the upper portion 31 of the guide 30 is integral with the flange 45. This minimizes the number of constituent parts providing the guidance of the pusher 15 to the extent that when of the assembly, the upper portion of the guide is secured to the flange 45.
- the outer seal 37 is placed against the shoulder of the lower portion 32 of the guide 30 while the inner seal 36 is placed inside the shoulder carried by the holding flange 45, the lower part 32 then being fitted into the flange 45.
- the guide 30 consists of a single portion 50 of generally cylindrical shape.
- the holding flange 51 has a thickness much greater than that of the flange 45 of the previous embodiments, so that the lower portion 50 of the guide 30 is fully housed inside the holding flange 51.
- the guide portion 50 is housed inside a bore 52 which has a reduction in diameter to accommodate the inner seal 36 between the diameter reduction of the bore 52 and the end of the guide portion 50.
- this body 2 is formed of two superimposed sections 55 and 56 and which are in contact along a joint plane 60. Inside the upper section 56 is movably mounted the pusher 15 while inside the lower section 55 is mounted oscillating most of the plunger 5.
- the holding flange 51 is in this case integral with the upper portion 56 of the body 2.
