Embodiment Construction

[0042] For convenience only, the following description refers specifically to espresso machines, but the invention is not limited to such machines and may be applied to machines for dispensing other beverages. Therefore, for the purposes of this specification and the appended claims, the term "coffee" must be read in its broadest sense so as to also include barley and the like.

[0043] figure 1 A schematic cross-sectional view of a piston machine according to an embodiment of the present invention is shown, with the piston in a low position. figure 2 Again a cutaway view of the same piston machine is shown, but with the piston in the high position. In the following description (and claims) terms such as "upper", "high", "lower" and "low" will be used. They are to be understood as non-limiting, but used with reference to the figures.

[0044] The machine is generally indicated by reference numeral 100 and comprises a cylinder 1 , a piston 2 , a spring 3 , a rod 4 , an oper...

Abstract

A machine (100) for espresso coffee of the piston type is described. The machine comprises a cylinder (1), a piston (2) which is configured to perform a translation movement in said cylinder, a rod (4) having an end cooperating with said piston (2), an operating lever (5), a spring (3), a member (6) configured to cooperate with said rod (4) and to move said piston (2) from a first position to a second position in which said spring (3) is at least partially compressed, and an opening (71) for introducing water into said cylinder (1) configured so as to introduce water above the piston (2).

Description

technical field [0001] The present invention generally relates to the field of machines for preparing beverages. More particularly it relates to a machine capable of dispensing brewed beverages such as coffee, espresso, barley or other similar beverages. The machine is of the piston type (also known as "lever type"). Background technique [0002] Many machines for preparing beverages are known. In particular, many machines are known for preparing espresso coffee from ground coffee, pods, capsules and the like. [0003] In particular, coffee machines of the "lever" or "piston" type are known. These machines generally include a system aimed at bringing the water required for producing coffee under pressure by utilizing the energy stored in a spring, which is preloaded by manual action. [0004] Typically, a piston machine includes a cylinder and a piston with a rod. The spring is mounted inside the cylinder. The piston is raised against the thrust of a spring driven by a...
