Machine for the production of coffee
First Claim
1. A machine for the preparation of drinks comprising:
- a boiler with a resistance for heating a liquid;
a pump to put said liquid under pressure within said boiler;
a hydraulic group to feed said liquid from said boiler through a capsule containing a portion of a preparation for a drink;
a conveyer moving said drink from said capsule to a collection container;
wherein said hydraulic group includes a distribution valve blocking the distribution of said liquid from said boiler to said capsule until a second operating threshold value is exceeded by the hydraulic pressure applied by said liquid, said second operating threshold value being between 4 and 10 bar; and
a hydraulic activation piston exiting from a body of said hydraulic group and placed within a capsule insertion duct, the exit direction of said piston essentially orthogonal with respect to a mouth and feeding the liquid in said capsule, said piston coupling with an edge of said capsule, the exit of said piston causing a compression and retaining said capsule against a counter-piece in correspondence with a conveying bottom of said duct.

Abstract
A machine for the preparation of drinks in capsules, particularly coffee, more particularly “Americano type coffee” or filter coffee or filtered coffee, of the type includes a boiler with a resistance for heating a liquid for the preparation of drinks, a pump for putting under pressure the liquid for the preparation of drinks, a hydraulic group for the feed of the liquid from the boiler through the capsule containing a portion of preparation for drinks with formation of the drink, and conveying means of the drink from the capsule to a collection container in which the hydraulic group includes a distribution valve blocking the distribution of the liquid for the preparation of drinks until a second operating threshold value is exceeded by the hydraulic pressure applied by the liquid for the preparation of drinks, this second operating threshold value being between 4 and 10 bar, preferably 4 and 6 bar.

18. A machine for the production of coffee comprising:
-
a boiler with a resistance for heating a liquid; a pump to put said liquid under pressure within said boiler; a hydraulic group to feed the liquid from said boiler through a capsule containing a portion of a preparation for a drink; a conveyer moving the drink from said capsule to a collection container; wherein said hydraulic group includes a distribution valve blocking the distribution of the liquid from said boiler to said capsule until a hydraulic pressure applied by said liquid is within a second operating threshold value between 4 and less than 5 bar; and
a hydraulic activation piston exiting from a body of the hydraulic group and placed within a capsule insertion duct, the exit direction of said piston essentially orthogonal with respect to a mouth and feeding the liquid in said capsule, said piston coupling with an edge of said capsule, the exit of said piston causing a compression and retaining said capsule against a counter-piece in correspondence with a conveying bottom of said duct. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
