Patent number: 11797030Abstract: A cartridge flow rate adjusting assembly of a hydraulic valve may include a rod having a first end and a second end, a shutter integrally formed with the first end of the rod and to slidingly positioned against a passage opening of the valve for adjusting flow. The assembly may also include an elastic element to hold the rod with the shutter in a monostable position with the opening of the valve. A plunger element may be integrally formed with the rod and interposed between the shutter and second end. The assembly may further include a conduit formed in the rod. The opening of the valve may be in fluid communication with a portion of the chamber disposed between the plunger and second end so that a pressure in the portion of the chamber is equal to a pressure in the passage opening.Type: GrantFiled: February 13, 2020Date of Patent: October 24, 2023Inventors: Samuele Molina, Giuliano Ruga, Marco Rosa Brusin, Paolo Arrus

Publication number: 20220243929Abstract: A hydraulic separator for hydronic systems for heating and/or cooling, including a hollow body with a casing, internally defining a chamber; at least two first through openings for the delivery of a fluid, and at least two second through openings for the return of the fluid, said first openings and said second openings being made on said casing of the body and being suitable to put in fluid communication said chamber to external circuits by hydraulic connecting means, further includes at least a mobile element suitable for separating said chamber of the body in a first portion and a second portion, in such a way to reduce the opening section of passage and of fluid contact between said first portion and said second portion. The invention further includes a control method for the hydraulic separator and hydronic systems for heating and/or coding.Type: ApplicationFiled: May 22, 2020Publication date: August 4, 2022Applicant: Giacomini S.p.A.Inventors: Samuele Molina, Marco ROSA BRUSIN, Paolo Arrus

Publication number: 20220090691Abstract: A multiway valve may include a generally cylindrical shaped hollow valve body having at least one handling opening and a plurality of through openings made on the outer wall of the valve body and defining a first group of connecting openings and a second group of connecting openings. A handling element may be pivotally disposed in the valve body and include at least two first through radial openings made on the outer wall of the cartridge. A tubular shaped fluidynamic insert may be housed inside the cartridge, and may have a second radial opening to let a fluid flow. The fluidynamic insert may also include a cell formed inside the cavity of the insert to define a homogeneous fluid flow rate.Type: ApplicationFiled: January 23, 2020Publication date: March 24, 2022Applicant: Giacomini S.p.

Patent number: 10928077Abstract: A multiway valve, comprising integrally connected first and second valves. Each valve comprises a valve body comprising a user port, a source port and an intermediate chamber placed therebetween, and a shutter inside the intermediate chamber, having a passage orifice for fluid to pass therethrough. The multiway valve comprises movement means allowing the shutters to move between a closed position where each passage orifice faces the inner walls of the respective intermediate chamber to an open position allowing the passage of the fluid between the user and source ports through the passage orifice. The first valve comprises a bypass duct formed in the shutter opening in fluid communication with the passage orifice. The bypass duct allows fluid communication between the intermediate chamber, the passage orifice, the duct, and the user and source ports of the first valve when the shutter is in its closed position.Type: GrantFiled: April 8, 2016Date of Patent: February 23, 2021Inventors: Paolo Arrus, Samuele Molina, Andrea Zuffellato, Giacomo Alberganti, Marco Rosa Brusin

Patent number: 10253888Abstract: A flow control valve includes a valve body with inlet and outlet ports, and an intermediate chamber therebetween. The valve further includes a static flow rate regulator for the fluid, accessible from outside the valve body and adapted to vary the cross-section of a passage orifice between the inlet and the outlet of the valve. The valve further includes a dynamic flow rate balancer, regulating flow rate based on a change of the incoming flow rate. The flow rate balancer includes a perforated element interposed between the inlet port and the intermediate chamber, allowing fluid passage only through at least one opening of the perforated element and an elastic element at one face of the perforated element facing the inlet port of the fluid into the valve body. An increase in the inlet/outlet differential pressure corresponds to an enlargement of the elastic element, guaranteeing a constant flow rate.Type: GrantFiled: May 18, 2016Date of Patent: April 9, 2019Assignee: GIACOMINI S.P.A.Inventors: Marco Rosa Brusin, Giacomo Alberganti, Paolo Arrus, Cesare Zoppis, Roberto Torreggiani
