Embodiment Construction

[0032] see figure 1 , which shows according to one embodiment of the present invention Diaphragm pump 10 , which is suitable for use in a beverage preparation module. Pump 10 is a diaphragm pump, also sometimes designated by the term membrane pump. A diaphragm pump is a positive displacement pump comprising a chamber with at least one flexible membrane inlet 40 . The membrane inlet 40 is deformable under the action of a piston 50 actuated by an eccentric 70 coupled to the motor 16 . The membrane inlet 40 is flexible and allows increasing or decreasing the volume of the chamber depending on its position, thus allowing control of the flow rate and pressure of the fluid delivered by the pump to the beverage module during beverage preparation. The pump 10 is also provided with an outlet check valve 60 to prevent reverse flow of liquid.

Abstract

The invention relates to a membrane pump (10) for a beverage preparation module delivering a fluid at a certain flow rate (F) and at a certain pressure (P) to the beverage preparation module: the pressure (P) and the flow rate (F) are chosen depending on the type of beverage to produce. The membrane pump (10) of the invention comprises an integrated by-pass valve (20) connecting a pump outlet (11) to a pump inlet (12) in order to reduce the flow rate (F) above a certain pressure (P1) value. The invention further relates to a beverage preparation module comprising a membrane pump (10) as the one described and configured to prepare a beverage from a beverage ingredient arranged in a container: the beverage preparation module comprises reading means configured to retrieve information from identification means in the container with the beverage preparation process parameters.

Description

technical field [0001] The present invention relates to a diaphragm pump for use in a beverage preparation module that delivers fluid at a specific pressure and flow rate to prepare a beverage, providing high in-cup quality and wide flexibility of use. The invention also relates to a beverage preparation module comprising such a pump. Background technique [0002] The field of the invention relates to beverage preparation machines, in particular machines using capsules with ingredients for the beverage to be prepared. Some beverage preparation machines use capsules containing ingredients to be extracted or dissolved and include filling means including a pump for a liquid, usually water, which is used to pump the liquid from a water source, either cold or Heated by a heating device such as a heating block or the like. [0003] Especially in the field of tea and coffee preparation, machines have been widely developed in which capsules containing beverage ingredients are inse...
