Definitions
- the invention relates to a supply connection device for a fluid pressure system.
- the invention relates more particularly to a supply branching device for a fluid pressure system, of the type in which a connector has a head intended to be received axially in a body of a supply inlet, and of the type wherein the connector is capable of being locked in the front position 'engaged axially in the supply inlet body by locking means.
- Such a supply connection device for a fluid pressure system is, for example, known from document FR-A-2,736,136.
- This document describes more particularly, a device of the type in which a connector is capable of being maintained in a position engaged axially inside the supply inlet of a receiving member by holding means, and in which it there is provided, on the one hand, a purge orifice of the receiving member and, on the other hand, a seal arranged between the head of the connector and the supply inlet, the connector sealingly sealing the purge orifice in the engaged position, called the locking position, and able to occupy a position partially retracted axially towards the rear, known as the purge position, in which it is held by holding means and in which the supply inlet is placed in leaktight communication with the purge orifice.
- each branch of the pin comprises a first cylindrical section and a second cylindrical section of larger diameter, the first cylindrical section cooperating with a first rear groove or a second front groove, formed in the connector to ensure maintenance thereof, respectively in the locking and bleeding positions.
- the second section of larger diameter allows the passage from the locking position to the purge position. More specifically, the operation of the device will be explained below.
- the operator To put the device in operation, that is to say in the locked position, the operator must proceed successively as follows: the connector is introduced into the body to its most advanced front axial position , and
- the pin is then engaged transversely in the body until the first cylindrical section of the pin is positioned in a first annular rear groove of the connector.
- the device is not easy to connect in the locking position by the operator because it is necessary for the first rear groove to be in axial coincidence with the locking means.
- This second series of operations consists in particular for the operator in re-engaging the pin transversely in order to maintain the connector, that is to say in repositioning the first cylindrical section in the front groove corresponding to the bleed position.
- this operation is only possible if the connector, therefore the front groove, is correctly positioned with respect to the pin.
- this second series of operations on the device has the same drawbacks as previously, it above all generates an additional safety problem.
- a purge operation is necessary to expel any gas such as air which may have entered the device, more particularly in a hydraulic member such as a receiver, and thus guarantee proper subsequent operation of the device.
- the operator purges the system, that is to say that it circulates pressurized fluid inside the hydraulic member, for example by creating a vacuum.
- pressurized fluid inside the hydraulic member
- Document DE-A-199.60.431 describes locking means between a first part and a second part which is attached to the first. These means consist of a generally symmetrical "U" pin further comprising a gripping part formed in a connecting section of the two branches of the pin. The branches have locking sections and stop strands at the free end of each branch which cooperate with ramps that comprise the first part.
- the pin is mounted in a slot of an additional intermediate piece which is axially clipped onto the first piece.
- the force exerted on the connecting part of the two branches of the pin for unlocking is a tensile force which is not natural for an operator, and which is in particular difficult to maintain during the unlocking operation. .
- the object of the present invention is to provide a supply connection device of the type mentioned above, which in particular makes it possible to remedy the drawbacks which have just been mentioned.
- the invention provides a device according to claim 1.
- the locking section of the locking means is repositioned by elastic deformation in the locked position as soon as the operator ceases to exert a release force on the locking means, so that the device is safer.
- the release force is a low pushing force, such as a thumb pressure by the operator, which must be applied to a connecting section of the locking means to cause elastic deformation.
- the operator By exerting a pushing force, the operator is in ergonomic working conditions, without risk of accidental dismantling and it is no longer necessary to provide means similar to the safety catch according to document DE-A-196 03 506.
- This also results in a simplicity of mounting the pin similar to what was known from FR-A-2,736,136. in the field of hydraulic connection devices.
- the friction of the locking means on the body occurs on external surfaces of the body so that no deterioration of the functional surfaces of the body is to be feared over time following repeated operations of the locking means, this thus preserves for example, the internal bore which participates in the guiding and sealing functions.
- the invention also provides a device, of the type in which the feed inlet body has a drain orifice and of the type in which at least one seal is arranged between the head of the fitting and the inlet of supply, characterized in that in the engaged position, the connector sealingly seals the drain orifice, and in that the connector can occupy a position partially retracted axially towards the rear, in which the supply inlet is in leaktight communication with the purge orifice.

- FIG. 1 is an exploded perspective view of a supply connection device for a fluid pressure system according to the invention, more specifically of its three main components, ie of a device 10 of the type in which a rear connector 30 comprises a front head 35 intended to be received axially in a front body 11 of a supply inlet 12, and of the type in which the connector 30 is capable of being locked in the engaged front position axially in the body 11 by locking means 60, these components 11, 30, 60 being each described in more detail below.
- the feed inlet body 11 is here integral at its front end with a hydraulic receiver (not shown) and essentially comprises, axially from front to back, a drain 13, an active part intended to receive and to cooperate with the locking means 60 and at its rear free end a supply inlet 12.
- the purge 13 is here produced in the form of a purge hole which is drilled radially in the body 11 and which opens inside the body into the supply inlet 12, thus bringing the supply inlet into communication with the outside of the body 11.
- the entire body 11, with the exception of the drain 13, has a first symmetry along a median transverse plane PTM, visible in FIG. 2A, and a second symmetry along a median axial plane PAM, visible in FIG. 2B.
- the active part of the body 11 essentially comprises a transverse notch 16 delimited axially and symmetrically along the PTM plane by two rings 14.
- the internal profile of the body 11 thus has symmetry along the median axial plane PAM as illustrated in FIG. 2A.
- the internal profile of the body 11 is a stage of revolution profile, complementary to that of the connector 30, which successively comprises from back to front, a first cylindrical section 22, a frustoconical intermediate section 23 and a second cylindrical section 24.
- the first section 22 of large internal diameter DU extends on either side of the transverse notch 16 and the second section 24 of small internal diameter DI2 extends on either side of the drain 13, the first section 22 being connected to the second section 24 by the frustoconical section 23.
- the body 11 thus comprises, axially behind the drain 13, a transverse notch 16 which extends over the major part of the circumference of the body 11 while having a generally complementary profile of the locking means 60 which can be introduced therein in the transverse direction T1.
- the transverse notch 16 has symmetry along the horizontal plane PAM as illustrated in FIG. 2B. More specifically, the transverse notch 16 extends in the thickness of the body 11 in its radially upper and inner parts, so that the notch 16 opens towards the outside and opens out towards the inside of the body 11, that is to say in the feed inlet 12.
- the complementary part of the notch 16, that is to say the remaining complementary material of the body 11 forms first and second sections 27G and 25D, respectively on the lateral faces left and right of the body, as best seen in Figure 2B.
- the first straight lateral section 25D is delimited, on the one hand, radially inwards by the bore 22 of the supply inlet 12 and radially on the outside by a plane face of tangential orientation and on the other part, symmetrically along the PAM plane, by a pair of inclined ramps 15, called opening ramps, which are inclined to the right.
- the second left lateral section 27G comprises a pair of inclined ramps 17, called main control ramps.
- the two rings 14, symmetrical with respect to the median transverse plane PTM of the notch 16 are here of a diameter substantially greater than that of the body 11, so that the rings 14 are prominent, at least over part of their circumference.
- each ring 14 comprises a succession of cam tracks and notches intended to cooperate with the locking means 60.
- each ring 14 thus comprises, from right to left and as visible in particular in FIGS. 2B and 2C, a cam path comprising an attack ramp 18, a notch 19 then a generally flat surface 20, and a clearance zone 21.
- the distance relative to the axis X of the flat 20 of the ring 14 is here slightly less than that of the body 11, as is also that of the clearance zone 21 relative to the flat 20.
- the locking means 60 here consist of a spring wire, elastically folded deformable. More particularly, the means consist of a pin 60 of general "U" shape lying horizontally by considering the figures.
- the pin 60 comprises substantially in the transverse plane PTM and symmetrically with respect to the axial plane PAM, two transverse branches 62 generally parallel and rectilinear, orthogonal to the axis X and connected together by a section of connection 61 such as a 180 ° semi-annular portion which offers a central or middle portion of manipulation oriented generally in a direction perpendicular to the branches 62.
- Each branch 62 of the locking pin 60 has a particular profile intended to cooperate on the one hand with the body 11, and on the other hand, with the connector 30 to perform different functions.
- each branch 62 thus comprises, going from the middle of the branch towards its free left end by considering FIG. 2B, a first section 64, a first bend 63, a second section 66, a second bend 65 and finally a strand 67.
- the first section 64 is curved here radially inwards to form a locking section 64 and the first elbow 63 forms an inflection point in the profile which is extended by a second section 66, called the control section.
- the strand 67 extends in a plane generally perpendicular to the transverse plane PTM and here asymmetrically, that is to say that the strands 67 of each branch 62, upper and lower respectively, extend one forward and the other rearward.
- the connector 30 essentially comprises, at the front, a head
- the connector 30 is here substantially tubular and has an internal channel 36 which opens at the front axial end of the connector and through which the pressurized fluid can flow from the supply inlet 12 to the pipe, or vice versa.
- the head 35 of the connector 30 comprises a stage profile complementary to the internal profile of the body 11 of the supply inlet 12 (the description of which was made previously), and more precisely the head 35 comprises, successively from back to front, a first rear cylindrical section 32, a first frustoconical section forming a ramp 37, a second frustoconical section 33 and a second cylindrical section 34.
- the first and second cylindrical sections 32, 34 are cylindrical sections which participate in guiding the head 35 of the fitting 30 respectively in the first section 22 and in the second section 24 of the body 11, the first section 32 having an external diameter DE1 greater than the external diameter DE2 of the second section 34.
- the second frustoconical section 33 is of shape complementary to that of the frustoconical section 23 of the profile of the body 11 connecting the first section 22 to the second section 24.
- An internal radial groove 39 is formed in the second section 34, at the front end of the head 35, in which is housed a seal 38 which cooperates with the second section 24 of the body 11 of the supply inlet 12, as best seen in the axial section view of FIG. 2A .
- the connection between the two frustoconical sections 33, 37 delimits a rear radial shoulder 41 and a groove 40 at "V" profile.
- the connection zone between the first frustoconical section 37 and the rear cylindrical section 32 has an internal radial locking groove 50.
- the second frustoconical section 33 has a maximum outside diameter which is generally equal to that DEl of the rear cylindrical section 32 and the first frustoconical section 37 has an outside diameter DE3 sufficiently smaller than the diameter DE2 so as to allow the passage of the branch 62 of the pin 60 during the unlocking operation, in particular for operating the connector head 35 from the locking position to the purge position as will be explained in detail below.
- the value of the diameter DE3 is therefore a function of the locking means 60, in particular here the diameter of the wire forming the pin 60.
- FIG. 2A illustrates a view in axial section of the connector 30 outside the body 11, as in FIG. 1.
- the connector 30 is then in a position which corresponds either to a position prior to its engagement forwards in the direction A1 in the feed inlet body 11, either in a position resulting from its total withdrawal from the body 11 after unlocking. It may or may not, prior to the engagement of the head 35 of the connector 30 in the supply inlet of the body 11, mount the pin 60 on the body 11 in a first position, called the unlocking position, as is illustrated in Figures 2B and 2C.
- the pin 60 can advantageously be pre-assembled in the locked position, as illustrated in FIG. 3B, the connector 30 then being force-fitted into the body 11.
- the pin 60 To carry out the mounting of the pin 60 in this first unlocking position, the pin 60 must be engaged transversely on the body 11 in the direction T1. More particularly, the branches 62 must be engaged opposite the notch transverse 16. During this engagement, the pin being opposite the notch 16, the strands 67 situated at the ends of the branches 62 will then come into contact with the driving ramps 18 of the rings 14 and the branches 62 will themselves come into contact with the drive ramps 15, the assembly having the effect, by cooperation of shapes, of causing the spacing of the branches 62 which will elastically deform radially outwards.
- the strands 67 will follow the surface formed by the attack ramps 15, until they automatically position themselves in the first notches 19, due to the elastic return effect. exercised by the branches 62.
- the pin 60 is then in the unlocked position, that is to say held on the body 11 in a captive manner.
- the pin 60 is in fact immobilized, on the one hand, transversely by its strands 67 in the first notches 19 and, on the other hand, axially at the level of the first elbow 63 by each front and rear lateral face of the notch 16 formed by the rings 26, as illustrated in FIGS. 2B and 2C.
- the unlocked position of the pin 60 no portion of the branches 62 does not interfere with the bore 22 and the head 35 of the connector 30 can be moved freely forwards or backwards inside the supply inlet 12.
- the connector is then in position to be locked, as can be seen in FIGS. 3A to 3B.
- the locking means 60 of a device 10 comprises a single pin 60, in a variant two pins for each of the positions, respectively locked and of bleeding of the connector 30 in the body 11.
- the various stage sections of the internal profile of the body 11 and of the head 35, respectively, are opposite.
- the first rear section 32 of the connector 30 faces the first section 22 of the body 11
- the second frustoconical section 33 of the connector 30 faces the frustoconical section 23
- the second cylindrical section 34 of the connector 30 is opposite the second section 24 of the body 11.
- the different stage sections, of the connector 30 and of the body 11 are dimensioned axially so that, in the locking position of the connector 30 in the body 11, on the one hand the seal 38 of the head 35 is in contact with the cylindrical wall 24 in front of the drain 13 in order to establish a sealed communication between the supply pipe
- the operator can carry out a visual check of the correct positioning of the connector 30, that is to say of the positioning of the groove 50 in axial coincidence with the transverse notch 16, before engaging for locking the branches 62 of the pin 60 in the groove 50 of the fitting.
- the locking means 60 To lock the connector 30 in the body 11, the locking means 60 must be operated from the unlocking position (FIG. 2B) to their locking position (FIG. 3B), that is to say exerting a force of pushed in the transverse direction T1 to continue the transverse engagement of the branches 62 in the notch 16. During this maneuver, the strands 67 of the pin 60, come out under the action of the force, the notches 19 to then travel through the flat 20 forming a cam path until the strands 67 are positioned in the area of release 21. The pin 60 is then in the so-called locking position.
- the pin 60 is, after maneuvering, in the locked position, that is to say that the locking section 64 of the pin 60 radially inward, is engaged in the groove 50 of the head 35, so that the connector 30 is held, axially in both directions, in position in the body 11 in which the fluid under pressure circulates.
- the strands 67 are positioned recessed in the clearance zone 21 relative to the body 11, this which reduces the radial size of the device, the strands 67 then being housed in a space radially delimited by the clearance zone 21 and the outer face of the body 11. In addition, this avoids any risk of accidental catching of the strands 67.
- the device illustrated in FIGS. 1 to 4 is a device provided with a purge 13, that is to say that the body 11 has a purge orifice 13 and that the connector 30 is a connector of the type which can occupy a first position of locking (in operation) and a second position moved axially towards the rear, called the purge position.
- the purge system 13 makes it possible in particular to expel from the device 10 any gas which could have been introduced into it or be trapped therein such as air and which is liable to harm the proper functioning of the device.
- the force to be exerted here is advantageously a pushing force on the pin 60, which is easy for the operator to do with a simple pressure of the thumb on the section 61 which is therefore exerted in the same direction as that for the transverse engagement of the pin in the body, that is to say radially from the outside in the direction of the axis.
- the control section 66 bearing on the ramp 17 moves transversely, moving away under the combined action of this pushing force and the shape ramps 17 by which an elastic deformation occurs, that is to say an opening towards the outside of the branches 62 of the pin, so that the first locking section 64 is no longer in contact with the connector 30 and that the latter can then be moved axially freely in the body 11 of the feed inlet in the direction A1 or in the opposite direction.
- the locking of the fitting 30 in the body is ensured as previously by the pin 60, more precisely by the locking sections 64 which are positioned in the second groove 40 of the fitting and resting on the shoulder. rear radial 41 as soon as the operator releases its pushing force on the pin 60.
- the seal In this position as visible in FIG. 3A, the seal cooperates behind the drain 13 with the cylindrical section 24 to ensure a rear seal so that the fluid cannot be evacuated otherwise than through the drain 13 .
- the cylindrical section 24 of the body 11 extends on either side of the drain 13 and the head 35 of the connector 30 has a single seal 38 to ensure the seal in the locking and locking positions, respectively. purge.
- the connector 30 comprises at least a second seal to ensure in particular the rear seal in the purge position, as is known from the prior art.
- the strands 67 of the pin 60 extend here in the opposite direction, that is to say respectively towards the front and towards the rear of the body 11 which allows a better balance of the pin 60.
- the pin 60 is perfectly reversible and can be placed on the body 11 without the operator having to respect a particular direction.
- the connector When the operator has purged the device 10, the connector must be returned to the locked position which corresponds to its operating position.
- the first frustoconical section 37 forms a ramp by its inclined rear face which tends to cause the radial spacing of the branches 62 of the pin 60 so as to allow the passage of the connector 30 in the axially engaged position, that is to say in the locked position.
- the locking sections of the pin 60 will move from the groove 40 to the rear groove 50 into which they fall automatically by simple elastic return effect.
- the operator does not have to manipulate the pin 60, but he must simply exert an axial force towards the front on the connector 30.
- FIG. 5 illustrates an alternative embodiment of the invention.
- the device 10 is a simple device with a single locking position in which the body 11 does not have a purge system 13 and the head 35 of the connector 30 is simplified in that it has only one groove 50.
- the operation of such a device is identical to that described above, in particular for FIGS. 3A to 3C which illustrate a connector in the locked position.
- the locking means are identical for a device with or without purging, which allows standardization by which it is possible in particular to reduce the production cost of the locking means.
- FIGS. 6 to 9 illustrate a second embodiment according to the invention, in which the locking means 60 are similar to those of the first mode and consist of a pin of general "U" shape, comprising two branches 62 which are generally parallel and rectilinear, linked together by a connecting section 61.
- the locking means 60 can be produced in different ways, thus the means can consist of a pin 60 of toric section, square or rectangular, metallic or made of synthetic material and which can be produced by any means.
- the pin 60 here of rectangular section, is for example made by molding a synthetic material and is simplified compared to that of the first embodiment in that, on the one hand, it does not have first and second bends and, on the other hand, in that the strands 67 do not extend axially relative to the branches 62 but in the same median transverse plane PTM.
- This type of pin 60 advantageously makes it possible to simplify the body 11, in particular the rings 14, comprising a cam track and specific notches to cooperate with the strands 67 can be omitted, this cam track and this notch being produced in the notch 16 more particularly on the sections 27G and 25D to cooperate the strands 67 which are here in the median transverse plane of the notch 16.
- Figures 6 and 7 illustrate, similarly to Figures 2B and 2C, a pin 60 mounted on the body 11 in a position, called the unlocking position.
- the pin 60 is advantageously retained by its strands 67, oriented radially inwards, which cooperate with the notches 19 so that the pin 60 is captive.
- Figure 8 illustrates the pin 60 in a locked position similar to Figure 3B.
- the locking sections 64 of the pin 60 extend transversely in the groove 50 to lock the connector 30 in the position engaged axially forward.
- FIG. 9 is a figure similar to FIG. 4B which illustrates the pin 60 when a release force is applied to the connection section 61 in the direction T1, in particular to allow passage of the connector 30 from its operating position in intermediate purge position, the deformation of the branches being obtained by cooperation of the chamfered free ends 66 of the branches 62 with the ramps 17.
- the chamfered ends 66 also facilitate the mounting of the pin 60 on the body 11.
