Description

La présente invention concerne un régulateur de pression d'essence pour l'alimentation d'un moteur à combustion interne de véhicule automobile plus particulièrement pour moteur du type dit à injection monopoint.The present invention relates to a fuel pressure regulator for supplying an internal combustion engine of a motor vehicle, more particularly for an engine of the type known as single-point injection.

Il est connu de réguler cette pression d'essence en tenant compte de la variation de pression existant en plusieurs points de la tubulure du moteur, et notamment au niveau du papillon d'admission d'air en amont et en aval de celui-ci. Ces pressions sont appliquées à un régulateur de pression d'essence constitué par des membranes délimitant des chambres dans un boitier, et reliées entre elles mécaniquement. Il est connu de les relier rigidement ce qui pose des problèmes d'industrialisation par une difficulté de montage des différentes parties du boitier. Il est aussi connu d'effectuer la liaison par contact pontuel ce qui ne permet pas d'assurer un parallélisme satisfaisant des membranes entre elles et leur positionnement correct par rapport au boitier et consé- quenment peut entraîner une imprécision dans le fonctionnement du régulateur.It is known to regulate this fuel pressure by taking into account the pressure variation existing at several points of the engine manifold, and in particular at the level of the air intake throttle upstream and downstream thereof. These pressures are applied to a fuel pressure regulator constituted by membranes delimiting chambers in a housing, and connected together mechanically. It is known to connect them rigidly, which poses problems of industrialization by a difficulty in mounting the different parts of the case. It is also known to make the connection by pontic contact which does not ensure satisfactory parallelism of the membranes between them and their correct positioning with respect to the housing and consequently may cause inaccuracy in the operation of the regulator.

La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un régulateur de pression d'essence de l'alimentation d'un moteur à combustion interne de véhicule automobile du type commandé à partir des variations de pressions existantes en différents points de la tubulure du moteur, et constitué d'un boitier dans lequel sont réalisées plusieurs chambres séparées par des membranes souples rigidifiées en leur partie centrale par des coupelles reliées entre elles et dont une des membranes est solidaire d'un clapet dont elle commande le déplacement par rapport à l'ouverture d'une buse débouchant dans une des chambres, régulateur caractérisé en ce que les membranes sont maintenues parallèles entre elles au moyen d'entretoises disposées pendant le montage du régulateur lors du sertissage du boitier, dans deux des chambres consécutives, chaque entretoise prenant appui de part et d'autre de la chambre la contenant contre les coupelles de rigidification des membranes délimitant lesdites chambres.The present invention aims to remedy these drawbacks and for this purpose relates to a fuel pressure regulator for the supply of an internal combustion engine of a motor vehicle of the type controlled from the pressure variations existing at different points. of the engine manifold, and consisting of a box in which are produced several chambers separated by flexible membranes rigidified in their central part by cups connected to each other and one of the membranes of which is integral with a valve the displacement of which it controls relative to the opening of a nozzle opening into one of the chambers, regulator characterized in that the membranes are kept parallel to each other by means of spacers arranged during the mounting of the regulator during crimping of the housing, in two of the consecutive chambers , each spacer bearing on either side of the chamber containing it against the stiffening cups of the membranes delimiting said rooms.

La description qui va suivre en regard des figures annexées fera mieux comprendre comment l'invention peut être réalisée.

  • La figure 1 représente en coupe un régulateur de pression conforme à l'invention disposé dans un circuit schématisé de l'alimentation d'essence d'un moteur à combustion interne pour véhicule automobile.
  • La figure 2 représente en vue agrandie la partie A encerclée de. la figure 1 dans une des positions possibles de fonctionnement du régulateur de pression.
  • La figure 3 représente en vue agrandie la partie A dans une autre position de fonctionnement du régulateur.
The description which follows with reference to the appended figures will make it easier to understand how the invention can be implemented.
  • Figure 1 shows in section a pressure regulator according to the invention arranged in a schematic circuit of the fuel supply of an internal combustion engine for a motor vehicle.
  • Figure 2 shows in enlarged view the encircled part A of. Figure 1 in one of the possible operating positions of the pressure regulator.
  • Figure 3 shows in enlarged view part A in another operating position of the regulator.

Le dispositif représenté à la figure 1 concerne plus particulièrement un moteur à injection du type dit "monopoint" . Pour cela un injecteur 25 est positionné en amont du papillon 24 et est alimenté à partir d'un réservoir 21 à travers une pomper P. Un régulateur de pression d'essence 1 complète le circuit d'alimentation d'essence et régule la pression d'essence appliquée à l'injecteur 25, au moyen du déplacement d'un clapet 9 qui assure l'ouverture ou la fermeture d'une buse 10 de retour d'essence vers le réservoir 21.The device shown in Figure 1 relates more particularly to an injection engine of the type called "single point". For this, an injector 25 is positioned upstream of the throttle valve 24 and is supplied from a tank 21 through a pump P. A fuel pressure regulator 1 completes the fuel supply circuit and regulates the pressure d gasoline applied to the injector 25, by means of the displacement of a valve 9 which ensures the opening or closing of a nozzle 10 for returning gasoline to the tank 21.

Ce clapet 9 est commandé par le déplacement d'une membrane souple6 d'au moins une chambre soumise à la variation de pression en un point du moteur.This valve 9 is controlled by the displacement of a flexible membrane6 of at least one chamber subjected to the pressure variation at a point in the engine.

Dans un tel dispositif d'injection le débit de l'essence est fonction de la pression manifold Pm mais indépendant de la pression Ps régnant à la sortie de l'injecteur 25 dans la tubulure d'admission en amont du papillon 24.In such an injection device, the gasoline flow rate is a function of the manifold pressure Pm but independent of the pressure Ps prevailing at the outlet of the injector 25 in the intake manifold upstream of the butterfly valve 24.

Or la pression Ps, surtout dans le cas de fonctionnement d'un moteur turbo compressé varie très fortement notamment lors de la mise en fonctionnement ou de l'arrêt de la turbine, il est donc nécessaire de faire varier d'autant la pression d'essence Pe pour compenser les variations de pression Ps qui règnent en sortie de l'injecteur.However, the pressure Ps, especially in the case of the operation of a turbocharged engine varies very greatly, in particular when the turbine is put into operation or stopped, it is therefore necessary to vary the pressure of petrol Pe to compensate for the pressure variations Ps which prevail at the outlet of the injector.

Pour ce faire et conformément à l'invention le régulateur de pression d'essence 1 est constitué d'un boitier dans lequel sont réalisées une pluralité de chambres 2 à 5 délimitées par des membranes 6,7,8 déformables élastiquement et rigidifiées en leur partie centrale de façon connue par des coupelles métalliques 14 à 19.To do this and in accordance with the invention, the fuel pressure regulator 1 consists of a housing in which a plurality of chambers 2 to 5 are produced delimited by membranes 6,7,8 elastically deformable and rigidified in part central in known manner by metal cups 14 to 19.

La chambre 2 qui régule la pression d'essence "Pe" représentative de la pression de l'essence au niveau de l'injecteur 25 est remplie d'essence qui arrive par une buse d'admission 11 et est refoulée par une buse de retour 10 et contient le clapet 9 qui suit les déplacements de la membrane souple 6 afin d'assurer l'ouverture ou la fermeture de la buse de retour 10.The chamber 2 which regulates the petrol pressure "Pe" representative of the petrol pressure at the level of the injector 25 is filled with petrol which arrives by an intake nozzle 11 and is discharged by a return nozzle 10 and contains the valve 9 which follows the movements of the flexible membrane 6 in order to ensure the opening or closing of the return nozzle 10.

La chambre 3 qui jouxte la chambre 2 est soumise à la pression atmosphérique "Pa" par un orifice à l'air libre 12.The chamber 3 which adjoins the chamber 2 is subjected to atmospheric pressure "Pa" by an orifice in the open air 12.

La chambre 4 jouxte la chambre 3 et est soumise à la pression "Pm" dite "manifold" par une buse 29 reliée en 23 à la pipe d'admission du moteur en aval du papillon 24.The chamber 4 adjoins the chamber 3 and is subjected to the pressure "Pm" called "manifold" by a nozzle 29 connected at 23 to the intake pipe of the engine downstream of the butterfly valve 24.

La chambre 5 jouxte la chambre 4 et est soumise par une buse 13 à la pression "Ps" existante en un point 22 en amont du papillon et en sortie de l'injecteur 25.The chamber 5 adjoins the chamber 4 and is subjected by a nozzle 13 to the pressure "Ps" existing at a point 22 upstream of the butterfly valve and at the outlet of the injector 25.

La membrane souple 6 porteuse du clapet 9 est commune aux chambres 2 et 3 et est rigidifiée en sa-partie centrale par une coupelle14 située dans la chambre 2 et une coupelle 15 située dans la chambre 3.The flexible membrane 6 carrying the valve 9 is common to chambers 2 and 3 and is stiffened in its central part by a cup 14 located in chamber 2 and a cup 15 located in chamber 3.

Une membrane souple 7 de surface sensiblement double de celle de la membrane 6 sépare la chambre 3 de la chambre 4 et comporte elle aussi une coupelle 16 située dans la chambre 3 et une coupelle 17 dans la chambre 4 laquelle chambre 4 est séparée de la chambre 5 par une membrane souple 8 de même surface que celle de la membrane 6, et qui comporte une coupelle 18 dans la chambre 4 et une coupelle 19 dans la chambre 5.A flexible membrane 7 with a surface substantially double that of the membrane 6 separates the chamber 3 from the chamber 4 and also includes a cup 16 located in the chamber 3 and a cup 17 in the chamber 4 which chamber 4 is separated from the chamber. 5 by a flexible membrane 8 with the same surface as that of the membrane 6, and which comprises a cup 18 in the chamber 4 and a cup 19 in the chamber 5.

Un ressort 20 est disposé dans la chambre 5 et prend appui contre le boitier d'une part et contre la coupelle 19 d'autre part.A spring 20 is disposed in the chamber 5 and bears against the housing on the one hand and against the cup 19 on the other hand.

Afin d'éviter toute réponse erratique par une mauvaise position des membranes entre elles il est nécessaire de les maintenir parallèles entre elles pour cela des entretoises sont disposées au montage de lacapsule dans les chambres 3 et 4 en prenant appui de part et d'autre desdites chambres et peuvent avantageusement être, tel que représenté à la figure 1, les coupelles 15 et 18 elles-mêmes, ainsi sont-elles déjà solidaires des membranes 6 et 8 concernées lors des différents sertissages du boitier 1 entraînant une économie très nette. du temps d'assemblage et conséquemment du prix de revient.In order to avoid any erratic response by a bad position of the membranes between them, it is necessary to keep them parallel to each other. For this, spacers are arranged for mounting the capsule in the chambers 3 and 4, taking support on either side of the said membranes. chambers and can advantageously be, as shown in Figure 1, the cups 15 and 18 themselves, thus they are already integral with the membranes 6 and 8 concerned during the different crimps of the housing 1 resulting in a very clear economy. assembly time and therefore cost price.

Afin d'éviter tout glissement de l'extrémité libre des coupelles 15 et 18 il peut être prévu sur les coupelles leur faisant face 16 et 17 tout moyen de positionnement tels que des picots 30 obtenus de matière dans lesdites coupelles 16 et 17.In order to avoid any sliding of the free end of the cups 15 and 18, any positioning means such as pins 30 obtained from material in said cups 16 and 17 can be provided on the cups facing them 16 and 17.

Les trois membranes 6,7 et 8 sont ainsi maintenues en appui entre elles et commandent le déplacement du clapet 9 constitué par une soupage plane 26 maintenue dans une cage 28 solidaire de la membrane6 et repose sur un support élastique 27 apte à absorber les différences de parallélisme entre la soupape 26 et`1a buse de retour 10.The three membranes 6, 7 and 8 are thus held in contact with each other and control the movement of the valve 9 constituted by a plane valve 26 held in a cage 28 integral with the membrane 6 and rests on an elastic support 27 capable of absorbing the differences in parallelism between the valve 26 and return nozzle 1a `10.

Le support élastique 27 pouvant être une rondelle ondulée commercialisée sous le nom "Onduflex" tel que représenté sur les figures 2 et 3 ou tout autre élément élastique apte à assurer un contact intime entre la surface plane de la soupape 26 et l'ouverture de la buse 10 quelle que soit leur position respective.The elastic support 27 can be a corrugated washer sold under the name "Onduflex" as shown in FIGS. 2 and 3 or any other elastic element capable of ensuring intimate contact between the flat surface of the valve 26 and the opening of the nozzle 10 whatever their respective position.
