Problems solved by technology

A disadvantage of this device relates to the high tension keeping a significant squeeze on the tubes, which quickly damages them so that they no longer regain their original elasticity, (disadvantage also relates to) lack of stability in different positions and lack of smoothness due to tensioning of leaf springs causing significant tension

Embodiment Construction

[0041] The device according to the invention can be used for figure 1 In a beverage maker indicated by reference number 1, for example a coffee machine.

[0042] according to figure 1 The machine typically includes a water source, such as a tank 10 containing water at ambient temperature (room temperature). A water supply system 2 is provided, which leads from a water tank to a brewing module 3 (brewing module), in which ingredients such as coffee, tea, etc. are brewed. The brewing module may be designed to receive a capsule, sachet or any other suitable packaging containing the ingredients. The module may be designed to be pressurized by brewing fluid. The pressure in the module and / or package can be up to several bars, for example 50-20 bars. For this purpose, a pump 4 is provided to supply the module with pressurized water. A suitable pump may be a piston or diaphragm pump, or a peristaltic pump. The water supply system comprises two water supply system branches const...

Abstract

Drink preparing machine comprising a tank (10), a water supply system(2) comprising at least a section(5) for heated water and a section(6) for unheated water, a pump (4) for conveying water from thetank through the supply system(2) as far as a module (3) for preparing the drink, and a valve device (7) arranged so as to control the selective opening and closing off of the supply systemsections (5, 6). The valve device (7) is a peristaltic system comprising compression means compressing a tubeof each supply systemsectionand acting under the effect of elastic return means.

Description

technical field [0001] The present invention relates to a control device having a peristaltic valve which allows the selective opening and closing of a water supply pipe to be controlled. The invention may in particular be advantageously applied to beverage dispensing machines, in particular for controlling the selective opening and closing of a plurality of supply pipes, for example hot water supply pipes and cold water supply pipes. Background technique [0002] Lever controls with peristaltic valves exist for a variety of applications. [0003] Patent US 3,861,834 relates to a mixer comprising means for selectively clamping two tubes and using cams acting in association with compression levers. [0004] Patent US 4,328,834 relates to a pinch valve for an iron using a rocker to selectively squeeze two tubes against a convex surface to selectively allow water or steam to pass through. [0005] Patent US 4,061,142 relates to a device for controlling blood flow through two ...
