Abstract

The switch has a body (1) with a plug (2) and measuring rod (3) which is interposed between a thermostatic head and a tap with return spring. The switch body contains a mechanical linkage (4,5,6,) which couples the thermostat rod (3) to the tap spindle. The operation of the mechanical linkage is governed by the position of a slider (7) which has a pin (8) able to move along a slot in a pivoted rocker arm (4) and to depress it's end in winter against a spring (10) which is stronger than the tap spring. In the summer position, the tap movement is equal but opposite to the thermostat movement but in summer the two are equal and in the same sense.

La présente invention concerne un dispositif mécanique de commutation Hiver/Eté pour robinets thermostatiques
Les robinets thermostatiques sont traditionnellement utilisés sur les radiateurs de chauffage pour réguler la température d'ambiance du local
Le dispositif selon l'invention apporte une solution pour commuter mécaniquement les robinets thermostatiques pour équiper les radiateurs utilisés en rafraichissement en plus du chauffage sur un circuit alimenté en eau, froide l'Eté et chaude l'Hiver.
The present invention relates to a mechanical winter / summer switching device for thermostatic valves.
Thermostatic valves are traditionally used on heating radiators to regulate the room temperature of the room
The device according to the invention provides a solution for mechanically switching the thermostatic valves to equip the radiators used for cooling in addition to heating on a circuit supplied with water, cold in summer and hot in winter.

Le dispositif possède les caractéristiques suivantes: - il s'insère entre le corps du robinet et à la tête thermostatique pour modifier la relation entre ces deux éléments, - I'action de la tête thermostatique sur le clapet du robinet qui s'effectuait directement, se fait maintenant par l'intermédiaire d'un système articulé, - le système articulé est positionné par un tiroir manuel de commutation HiverlEté qui permet par un changement approprié des bras de levier mis en jeu, de sélectionner le sens de l'action précédemment décrite (action inverse en commutation Eté, action directe en commutation Hiver), - en commutation Eté, le système articulé est maintenu au contact de l'actionneur de la tête thermostatique par un ressort de compression supérieure et s'opposant à celle du ressort de valve du robinet, - le dispositif peut être intrégré à la tête thermostatique du robinet pour une réalisation plus compacte des commandes du robinet.The device has the following characteristics: - it is inserted between the body of the valve and the thermostatic head to modify the relationship between these two elements, - the action of the thermostatic head on the valve valve which was carried out directly, is now done by means of an articulated system, - the articulated system is positioned by a manual Wintering switching drawer which allows, by an appropriate change of the lever arms involved, to select the direction of action previously described (reverse action in summer switching, direct action in winter switching), - in summer switching, the articulated system is kept in contact with the actuator of the thermostatic head by a higher compression spring and opposing that of the valve spring of the valve, - the device can be integrated into the thermostatic head of the valve for a more compact realization of the valve controls.

La figure (4) représente en coupe, le dispositif selon l'invention dans une variante de verrouillage du tiroir intégré à la tête thermostatique du robinet
En référence à ces dessins, le dispositif comporte: - un corps (1) avec bouchons (2) et piges (3), le tout inséré entre le corps du robinet et la tête thermostatique . Ces dernières pièces sont représentées en trait fin. Les bouchons et les piges respectent les formes et les positions d'origine des pièces - un culbuteur (4) associé à une tige (5) et une palette (6) formant un système articulé qui rétablit l'action de la tête thermostatique sur le clapet du robinet - le culbuteur est lié à un tiroir (7) de positionnement manuel de commutation
Hiver/Eté par un axe (8) libre dans une lumière du culbuteur. Par déplacement du tiroir, les deux longueurs de bras de levier du culbuteur sont modifiables, par exemple 1/2 et 1 modifiables en (-)1/6 et 1/3, - la palette est liée au corps par un axe (9) et présente deux longueurs fixes de bras de levier, par exemple 1/2 et 1, - I'ensemble culbuteur-tige-palette-tiroir permet ainsi de réaliser en commutation
Eté, des déplacements sensiblement égaux et de sens opposés pour l'actionneur de tête thermostatique et pour la tige du clapet du robinet. Les déplacements sont égaux et de même sens en commutation Hiver - en commutation Eté, le culbuteur est maintenu au contact de l'actionneur de la tête thermostatique par un ressort de compression (10) d'action supérieure et s'opposant à celle du ressort de clapet du robinet, soit compte tenu des longueurs des bras de levier données en exemple, une action du ressort de compression de l'ordre de huit fois supérieure à celle du ressort de clapet. L'action combinée des deux ressorts équivaut à celle du ressort de clapet. Le ressort de compression est inactif en commutation Hiver, - le tiroir est verrouillé sur le corps par la bague (11), - une variante pour une réalisation plus compacte de l'ensemble des commandes du robinet consiste à intégrer le dispositif à la tête thermostatique du robinet. Les bouchons, les cales et la bague ne sont plus nécessaires et le verrouillage du tiroir est assuré par le volant de consigne de la tête thermostatique au moyen d'un verrou/ressort (12) engagé dans le tiroir Une ou deux positions (13) de désengagement du volant autorisent le positionnement manuel du tiroir de commutation Hiver/Eté.
Figure (4) shows in section, the device according to the invention in a variant of locking the drawer integrated in the thermostatic head of the tap
With reference to these drawings, the device comprises: - a body (1) with plugs (2) and pins (3), the whole inserted between the valve body and the thermostatic head. These latter parts are shown in thin lines. The plugs and rods respect the original shapes and positions of the parts - a rocker arm (4) associated with a rod (5) and a pallet (6) forming an articulated system which restores the action of the thermostatic head on the tap valve - the rocker arm is linked to a manual switching position drawer (7)
Winter / Summer by a free axis (8) in a rocker light. By moving the drawer, the two lengths of lever arm of the rocker arm can be modified, for example 1/2 and 1 can be modified in (-) 1/6 and 1/3, - the pallet is linked to the body by an axis (9) and has two fixed lengths of lever arm, for example 1/2 and 1, - the rocker-rod-pallet-drawer assembly thus makes it possible to achieve switching
Summer, substantially equal displacements and opposite directions for the thermostatic head actuator and for the stem of the valve flap. The displacements are equal and in the same direction in Winter switching - in Summer switching, the rocker arm is kept in contact with the actuator of the thermostatic head by a compression spring (10) of higher action and opposing that of the spring valve valve, or taking into account the lengths of the lever arms given as an example, an action of the compression spring of the order of eight times greater than that of the valve spring. The combined action of the two springs is equivalent to that of the valve spring. The compression spring is inactive during Winter switching, - the drawer is locked on the body by the ring (11), - a variant for a more compact embodiment of all the valve controls consists of integrating the device into the thermostatic head tap. The plugs, the shims and the ring are no longer necessary and the locking of the drawer is ensured by the reference wheel of the thermostatic head by means of a lock / spring (12) engaged in the drawer One or two positions (13) disengaging the steering wheel allow manual positioning of the winter / summer switch drawer.

Le dispositif selon l'invention est particulièrement destiné à la climatisation simplifiée des locaux déjà équipés de radiateurs sur un circuit alimenté en eau, chaude l'Hiver et froide l'Eté ; I'eau étant produite soit par deux unités séparées, soit par une unité combinée comme une machine à gaz à absorption à mode chaud ou froid ou comme une machine électrique du type pompe à chaleur réversible. The device according to the invention is particularly intended for the simplified air conditioning of premises already equipped with radiators on a circuit supplied with water, hot in winter and cold in summer; The water being produced either by two separate units, or by a combined unit like an absorption gas machine in hot or cold mode or like an electric machine of the reversible heat pump type.
