Abstract

The unit comprises a silent running air compressor (1), a reservoir for compressed air (8) and a small container with a reserve of lubrication oil (2). The compressor runs automatically and the oil level in the compressor is maintained by an electric control valve (4). The assembly is fitted into a cabinet (20) on castors for ease of maneuvering. The top of the cabinet is suitable for use as a work surface.

Description

La présente Invention concerne un dispositif de production d'air pour fauteuils dentaires Cet appareil comporte un compresseur hermétique muni d'un réservoir adapté pour assurer une pression constante de l'air produit. The present invention relates to an air production device for dental chairs. This device comprises a hermetic compressor provided with a reservoir adapted to ensure a constant pressure of the air produced.

Ses éléments sont logés dans un petit compartiment métallique de forme appropriée afin d'assurer un fonctionnement silencieux et de rehausser le design de l'ensemble. Its elements are housed in a small metal compartment of appropriate shape to ensure silent operation and enhance the design of the whole.

En effet, les compresseurs à air classiques en usage actuellement, se présentent sous forme d'un bloc mécanique bruyant et inesthétique et sont d'un usage malaisé. Indeed, conventional air compressors in current use are in the form of a noisy and unsightly mechanical block and are difficult to use.

Aussi, I'invention, objet du présent descriptif, appliqué au seul domaine des fauteuils dentaires, permet, d'une part, de remédier à ces inconvénients et, d'autre part, de proposer une nouvelle conception de procédé de production d'air. Also, the invention which is the subject of this description, applied only to the field of dental chairs, makes it possible, on the one hand, to remedy these drawbacks and, on the other hand, to propose a new design of air production process. .

L'invention peut connaître d'autres domaines d'application. The invention may have other fields of application.

Les avantages essentiels conférés et les améliorations apportées par rapport aux systèmes classiques sont les suivants
- suppression du bruit lors du fonctionnement du compresseur,
- accroissement considérable de la longévité et de la durée d'utilisation du compresseur par adjonction d'un procédé de lubrification original.The key benefits and improvements over traditional systems are as follows
- noise cancellation during compressor operation,
- considerable increase in longevity and service life of the compressor by adding an original lubrication process.

La conception robuste de ce compresseur permet une augmentation appréciable de la réserve d'air par rapport aux compresseurs conventionnels et, par voie de conséquence, de la pression d'air disponible limitée présentement à quatre et six bars (4.105 et 6.105 Pascals). The robust design of this compressor allows a significant increase in the air reserve compared to conventional compressors and, consequently, the available air pressure currently limited to four and six bars (4.105 and 6.105 Pascals).

Le compresseur (1) est relié à une réserve d'huile (2) par une tuyauterie (3) se terminant en forme de siphon et une électrovanne (4) est fixée à proximité du compresseur (1) libère le passage lors d'une baisse du niveau d'huile. The compressor (1) is connected to an oil reserve (2) by a pipe (3) ending in the form of a siphon and a solenoid valve (4) is fixed near the compressor (1) frees the passage during a drop in oil level.

Le compresseur est muni d'un voyant d'huile (5) sur le côté de ce dernier, I'aspiration d'air étant protégée par un filtre (7). L'envoi de l'air vers le réservoir (8) est lié par une tuyauterie (9) au compresseur (1); sur le côté de ce dernier un boîtier électrique (10) est alimenté au courant monophasé 220 volts. The compressor is fitted with an oil sight glass (5) on the side of the latter, the air intake being protected by a filter (7). The air sent to the tank (8) is linked by a pipe (9) to the compressor (1); on the side of the latter an electrical box (10) is supplied with single-phase current 220 volts.

Le compresseur est fixé par des cylinblocs (11) au siège du compartiment. Au dessus est posé le réservoir à air (8) maintenu par une structure métallique (12). Au dessous du réservoir d'air est situé un purgeur (13) muni d'une vanne manuelle (14) pour les condensats.  The compressor is fixed by cylinder blocks (11) to the compartment seat. Above is placed the air tank (8) held by a metal structure (12). Below the air tank is a drain valve (13) fitted with a manual valve (14) for the condensates.

Le dessus du réservoir d'air (8) comporte : une valve de sûreté (15), un manomètre (16) indiquant la pression et un manostat (17) réglable assurant l'alternance du compresseur et le maintien de la pression d'air. The top of the air tank (8) comprises: a safety valve (15), a pressure gauge (16) indicating the pressure and an adjustable pressure switch (17) ensuring the alternation of the compressor and the maintenance of the air pressure .

Sur le côté du réservoir est disposé un conduit de sortie d'air (18) muni d'une vanne d'arrêt (19) située sur la paroi inférieure du compartiment (20). On the side of the tank is arranged an air outlet duct (18) provided with a shut-off valve (19) located on the lower wall of the compartment (20).

Le compartiment est doté de quatre roulettes pivotantes (21) et, dispose d'une portière (22). Sa fermeture est assurée par des aimants (23). Il présente l'aspect d'une table mobile aux angles arrondis. The compartment has four swivel casters (21) and has a door (22). Its closure is ensured by magnets (23). It has the appearance of a mobile table with rounded corners.

La portière est munie d'un bouton électrique (24) et de trois voyants indiquant : - la mise sous-tension - la marche du compresseur - I'arrêt par un manostat (17), ainsi qu'un contacteur (25) à deux positions fixé sur le côté intérieur pour l'alimentation électrique du compresseur (1) ou de l'électrovanne (4). The door is fitted with an electric button (24) and three indicator lights indicating: - power on - compressor on - stop by a pressure switch (17), as well as a two-way contactor (25) positions fixed on the inner side for the power supply to the compressor (1) or the solenoid valve (4).

Le compartiment est doté d'une grille d'aération (26) pour l'aspiration d'air du compresseur. The compartment has a ventilation grille (26) for the air intake from the compressor.

Le compresseur à air est incorporé dans un compartiment. The air compressor is incorporated in a compartment.

On obtient une réduction considérable de son volume acoustique à peine audible durant l'activité. We obtain a considerable reduction in its barely audible acoustic volume during the activity.

II est doté d'un réservoir d'huile et d'une électrovanne. It has an oil tank and a solenoid valve.

Lors du fonctionnement, il émet une infime quantité d'huile qui accroît considérablement la longévité et la durée d'utilisation de l'ensemble  During operation, it emits a tiny amount of oil which considerably increases the longevity and duration of use of the assembly
