Abstract: A dosage valve for a fluid product, for example a colorant, comprising an at least partly elastic or elastomer element, having at least a cut in the central part so as to define at least two closed/open cooperating lips, which comprises a sensor element associated with the at least partly elastic element in order to detect at least a closed or open condition of the lips.

Abstract: A device to prevent the exsiccation of fluid products in a delivery head of a dispensing machine for said fluid products. The device comprises a first element able to generate a flow of air mixed with steam or with at least a solvent, and a second element able to convey the flow towards a zone underneath the delivery nozzles of the delivery head and to create in said zone a determinate atmosphere, different from the atmosphere in the environment where the dispensing machine is to be found during use. The device also comprises detection elements arranged in proximity with the delivery head and able to detect one or more significant parameters of said determinate atmosphere, and a regulation circuit able to regulate one or more characteristics of said flow according to the values detected by the detection elements in order to maintain the significant parameters of the determinate atmosphere within a set of pre-determined values.

Abstract: A device and a method for preventing the drying of fluid products in a delivery head of a machine for dispensing fluid products, wherein the delivery head is provided with a plurality of delivery nozzles. The device comprises first elements to generate a conditioning flow, second elements to convey the conditioning flow towards a space underneath the delivery nozzles and create in said space an atmosphere different from that of the environment in which the dispensing machine is to be found during use. The delivery nozzles are divided into at least two groups and the space is divided into at least two distinct conditioning zones, disposed in correspondence with the groups of delivery nozzles. Different atmospheres are created in the conditioning zones, according to the type of fluid product delivered by the corresponding group of delivery nozzles.

Abstract: Device (10) and method for preventing the drying of fluid products in a delivery head (12) of a machine for dispensing fluid products, wherein the delivery head (12) is provided with a plurality of delivery nozzles (11). The device (10) comprises first elements (25) to generate a conditioning flow, second elements (15, 20, 21) to convey the conditioning flow towards a space (19) underneath the delivery nozzles (11) and create in said space (19) an atmosphere different from that of the environment in which the dispensing machine is to be found during use. The delivery nozzles are divided into at least two groups and the space (19) is divided into at least two distinct conditioning zones (19a, 19b, 19c, 19d), disposed in correspondence with the groups of delivery nozzles (11). Different atmospheres are created in the conditioning zones (19a, 19b, 19c, 19d), according to the type of fluid product delivered by the corresponding group of delivery nozzles (11).

Abstract: In a mixer for fluids, of the type including at least one clamping assembly (1) operable selectively for clamping, in use, a container of fluid products, a device is provided for controlling the clamping of the container which includes a sensor (8) mounted on the clamping assembly (1). The sensor (8) is disposed in a region of the clamping assembly (4) subjected, in use, to a force in a predetermined direction due to the compressive forces exerted on the container in the clamping state. The sensor (8) is further adapted to emit a continuous signal proportional to the force.
