Abstract: The invention relates to a control unit for the delivery of hot and cold water in mixer valves having two overlapping plates (11, 12) one of which is fixed and the other movable on the fixed one and in which the fixed plate has an outlet hole or opening (17) made from a semicircular side (17a) placed between two arched water inlet holes or openings (15, 16) with its center being in the center of the fixed plate and a side which extends and widens in a fan-shape in the other half of the fixed plate, symmetrically in respect to the axis of said plate passing through said two arched holes or openings.

Abstract: The invention relates to a pair of overlapping ceramic disks for the opening and closing of screw type valves, where there is a fixed disk (11) with lateral slots inside the valve body and another disk (12) which rests on top of the fixed one (11) and where the fixed disk (11;31) has at least one segment like slot (11a;31a) closed at the perimeter and the movable disk (12;32) has at least one lateral opening (12;32a) which is open both at the bottom towards the fixed disk and radially towards the lateral slots (13a) of the valve body, and closed at the top by a spoked surface so as to improve the water flow conditions.

Abstract: A screw type valve for the delivery of water in hydrosanitary installations with superimposed ceramic sealing disks, a fixed one (13) and a rotating one (15). The valve also comprises a sleeve (11) fitted into an externally threaded ring (10) and with a bottom ring (12) bearing the fixed ceramic disk (13), a driving spindle (14) with said movable ceramic disk (15) on its bottom rotating inside said sleeve, while on its top end a control handle is fitted, said sleeve, ring and spindle being made of a plastic material, while the threaded ring is made of metal to allow a safe installation of the valve.

Abstract: The invention relates to an antinoise baffle especially for screw type valves having a first ceramic disk (13) fixed in the body with at least one hole (13a) for the flow of water, a second ceramic disk (14) resting against and rotating on the first with at least one lateral slot (14a) positionable in correspondence to and away from the one of the first disk following a quarter or half rotation of the second disk. At least one net (21) is placed and blocked of the second disk (14) and has at least one wing which extends towards the first disk near to one or each lateral slot (14a) or said second disk, the wings extending between said slot and the opening (20) for the outlet of water.

Abstract: The invention relates to a water flow control unit in mixing valves for hot and cold water comprising two overlapping ceramic disks (11,12) one of which is fixed and the other movable. The fixed disk (11) has two inlet holes (15,16) which are substantially of uniform width and are symmetrically cut, with respect to a water dividing partition (b 19), into one half of the same disk. The fixed disk (11) also has an elliptic shaped outlet hole where one part is placed between the two inlet holes or openings (15,16) and the other part extends into the other half of the fixed disk. The movable disk (12) has a mixing chamber defined by a circular part (18a) off-center from the middle of the same disk and a communicating polygonal part (18b).

Abstract: The present invention relates to hot and cold mixer valves which have cartridge type bodies and valvular means made up of overlapping ceramic disks in which flows of cold and hot water is controlled by the valvular means with independent controls, that is to say with two separate control levers, one for hot water and one for cold water.

Abstract: Mixing tap for hot and cold water fitted with a mixing ball with inlet holes matched with the separate hot and cold water feed pipes and outlet holes delivering the mixed water to a spout. At least the part of the ball with holes is made of a ceramic material and interacting with seals also made of ceramic material and coordinated to the hot and cold water feed pipes. Each ceramic seal is supported by an elastomer bellow type element acting both as a spring pushing the seal against the ball and as a radial packing around the seal itself.

Abstract: Locking device to fit a mixing valve for hot and cold water into the body of a tap, in particular a locking nut bearing on the cover of the body of the mixing valve by interposing suitable elastic means to compensate eventual plays and distribute the locking load.

Abstract: The object of the invention is a pair of superimposed ceramic disks (11,12) to open and close screw type valves, one of said disks (11) being fixed and the other one (12) being movable on the fixed disk, where each of said disks presents a slot or opening (15,16) composed by a segment portion (15',16') and by a tapered curved portion (15,",16") extending from one end of said segment portion, the slot or opening (15) of one disk (11) being turned in a direction which is opposite to the direction of slot (16) in the other disk (12), so that when opening the valve the tapered curved portions (15",16") are the first to superimpose to gradually increase the flow of the delivered liquid.

Abstract: The invention relates to a mixing valve for hot and cold water comprising a cartridge type body, two overlapping disks, one fixed and the other one movable, which interact in opening and closing the water ducts, and a rotating and pivoted control lever to displace and position the movable disk on the fixed one to open or close the water flow. Said control lever is assisted by a slide gate to control the maximum water output by limiting the oscillation of the lever and by a ring designed to adjust the temperature of the mixed water by limiting the rotation of said control lever.

Abstract: The invention relates to a `breech-block` valve for the delivery of cold or hot water with ceramic sealing plates in which a ring which is capable of independent axial displacements is fitted on the base of the valve body in order to take up and compensate for machining play and to stabilize the compacting force on the sealing ceramic plates by means of annular elastic packings independently of the force with which the valve is tightened within the tap body.
