Abstract
Equipment for the preparation of a hot beverage comprising a boiler capable of containing a liquid component of the beverage, for example water, a collection container and means defining a delivery path for the liquid component from the boiler to the collection container. The equipment also comprises valve means located along the delivery path for the liquid component comprising a plug which can move between a position in which the delivery path is closed and one in which it is open and means to immobilise the plug in the open position. These means are arranged in such a way that they can be activated and deactivated by a force exerted in the direction of movement of the plug.
Claims124
Equipment for the preparation of a hot beverage, comprising a boiler designed to contain a liquid component of the said beverage, a collection container and means for defining a delivery path for the said liquid component from the boiler to the collection container,
- the said equipment also comprising valve means located along the delivery path for the said liquid component comprising a plug which can move between a position in which the delivery path is closed and one in which it is open and means to immobilise the plug in the open position,
- in which the said means to immobilise the plug are arranged in such a way that they can be activated and deactivated by a force exerted along the direction of movement of the plug.
Equipment for the preparation of a hot beverage, comprising a boiler suitable to contain a liquid component of said beverage, a collection container and means defining a delivery path of said liquid component from the boiler to the collection container,
- said equipment further comprising valve means being arranged along the delivery path of said liquid component comprising a plug moving between a closed position and an open position of the delivery path and means for immobilising the plug in the open position,
- wherein said means for immobilising the plug comprise means for generating friction along at least one portion of the travel of the plug relative to a portion of the equipment being fixed relative to the movement of plug to immobilise the plug in the open position.
Method for preparing a hot beverage comprising at least a first liquid component using a coffee-maker comprising a boiler and a collection container, the said method comprising the stages of:
- providing the coffee-maker with a quantity of the said first liquid component in the boiler,
- heating the boiler up to a predetermined excess pressure with respect to the atmospheric pressure in which a plug located along a delivery path for the first liquid component from the boiler to the collection container opens the said delivery path,
- immobilising the said plug in the position in which the delivery path is open until all the first liquid component and the steam present in the boiler have been delivered,
- in which the said plug is immobilised in or released from the said position in which the delivery path is open through a force which is exerted in the direction of movement of the plug.
Method for preparing a hot beverage comprising at least one first liquid component using a coffee-maker comprising a boiler and a collection container, said method comprising the steps of:
- arranging the coffee-maker with an amount of said first liquid component in the boiler,
- heating the boiler up to a preset overpressure relative to the atmospheric pressure at which a plug being arranged along a delivery path of the first liquid component from the boiler to the collection container opens said delivery path,
- immobilising said plug in the open position of the delivery path until the first liquid component and the steam contained within the boiler have been completely delivered,
- wherein said plug is either immobilised to or released from said open position of the delivery path by means of friction being generated between the plug and a portion of the equipment being fixed relative to the movement of the plug, said friction being suitable to maintain the plug in the open position.
