Abstract
Abstract A homogenizer device, in particular for the production of whipped cream, comprising in combination, the following components: an external sleeve and an internal sleeve between which is formed a convoluted labyrinth, the internal sleeve housing a valve element which forms with it a chamber communicating with said labyrinth and with the delivery tube for the base mixture, said valve element consisting of a stem bearing a valve at one of its ends and a valve at its opposite end, the former being a valve for controlling the dispensing of the whipped cream and the latter being a valve for controlling the conduction of the mixture through said labyrinth, said valve element being also translatable against a counteracting spring.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A homogenizer device, in particular for the production of whipped cream, comprising, in combination, a delivery tube, an external sleeve, an internal sleeve having teeth on the outside thereof to form a convoluted labyrinth with said external sleeve, a valve element housed by said internal sleeve which forms with it a chamber communicating with said labyrinth and with the delivery tube for the base mixture, said valve element consisting of a stem bearing a first valve head at one of its ends and a second valve head at its opposite end, said first valve head being a valve for controlling the dispensing of the whipped cream and the second valve head being a valve for controlling the conduction of the mixture through said labyrinth, and a spring, said valve element being also translatable against said spring.
