Embodiment Construction

[0028] Referring to the above-mentioned drawings and symbols, the accompanying drawings show an improved preferred embodiment of an espresso machine proposed by the present invention, the espresso machine comprising ( figure 1 to 4) a pump that pushes hot water under pressure so that the hot water passes through a quantity of ground coffee deposited in a filter 1 housed in the housing 2, which in turn is fitted in a filter holder 3, said The filter holder 3 has one or more outlet ducts 4 (preferably two outlet ducts) for brewing coffee.

[0029] Figure 5 with 6 One of these improvements is clearly shown. This improvement consists in the fact that at the center of the base of the housing 2 is fixed a ball valve 5 which is fitted against a helical compression spring 7 so that the ball 6 and the spring 7 are pushed into the valve chamber 11 of the valve 5 Among them, the valve chamber 11 communicates with the interior of the housing 2 and the cavity of the filter holder 3 thr...

Abstract

The invention relates to a coffee outlet of Italian coffee machine, wherein said Italian coffee machine comprises a pump for pushing and pressurizing hot water to grind the coffee powder deposited inside the filter (1) of frame (2); the frame (2) is mounted inside the filter holder (3); the filter holder (3) has one or several outlet channels (4) for watering said coffee. And the invention is characterized in that: the middle of base of frame (2) is fixed with a ball valve (5); the ball valve (5) is contacted with the screw compress spring (7), to push the roller (5) and spring (7) into the valve room (11) of valve (5); the valve room (11) is through to the frame (2) via relative upper and lower holes (9, 10), and through to the chamber of filter holder (3); the roller (6) is mounted between the lower part of upper hole (9) and the upper end of spring (7); and the spring (7) is mounted between the roller (6) and the lower hole (10) in downward taper shape while it is molded.

Description

technical field [0001] The present invention relates to domestic espresso coffee machines comprising a pump for pushing pressurized hot water so that the hot water passes through a quantity of ground coffee or single packets of coffee beans deposited in a filter housed in a housing , the housing is then fitted in a filter holder having one or more outlet ducts for brewing the brewed coffee. [0002] In particular, the present invention relates to a device for making foamed coffee (café crème) and to such a device designed so that when a coffee machine supplies coffee to two cups simultaneously, the amount of coffee provided in each cup is identical. Background technique [0003] Foam coffee is made from an emulsion of brewed coffee and air, which is obtained by pushing the coffee through thin tubes set in the housing, thereby increasing the pressure; after passing through these thin tubes, a Expansion, or a decrease in pressure, causes the brewed coffee to break up into ne...
