  • Such valves usually have a central valve body on which there are obtained the inflow port or ports and the outflow port or ports, each one of which is connected to the aforementioned branches of the hydraulic circuit.
  • the multi-way valves further comprise shutter devices which have the purpose of placing the inflow port or ports alternatingly in communication with the outflow port or ports.
  • shutter devices can be used in hydraulic devices different from a multi-way valve, such as for example in pumps, more precisely in membrane pumps.
  • the fact that the shutter device consists of several components assembled to each other could determine, disadvantageously, assembly defects that could in turn cause the presence of the aforementioned fissures or the occurrence of malfunctioning of the same shutter device.
  • the aim of the present invention is to overcome all the aforementioned drawbacks.
  • one of the objects of the invention is to provide a shutter device capable of avoiding the presence of fissures that could enable the leakage of the fluid that flows in the hydraulic circuit and the presence of impurities stagnation points and deposits of the same fluid.
  • Another object of the invention is to provide a shutter device that does not require the use of fixing means and avoids possible assembly errors.
  • an object of the invention is to provide a shutter device that provides for an implementation process that is less complex and thus more economic with respect to shutter devices of the prior art.
