PNEUMATIC AND FLOW PRESSURE REGULATOR, APPLIED IN A SOLID, GRANULATED, POWDERED MATERIAL DOSING DEVICE, MIXTURES AND SEEDS PROVIDED IN SEWING AND FERTILIZER MACHINES
“Pneumatic and flow pressure regulator, applied in a dosing device of solid, granular, powder, mixtures and seeds foreseen in sowing and fertilizing machines.” a pressure regulator suitable for use in a metering device of the type comprising a tolbín (b) which is located in communication with the bottom of the material receiving hopper (v), and has a lower feed opening, below which is a set of metering gears (e) mounted on the same transverse rotor axis (e) which, with its rotating movement, produces the dosage of the material that is discharged into a respective internal transverse chamber (a) where the material is sucked and sucked until the exit, through a respective closed and individual longitudinal passage (p), through which the flow of compressed air circulates from a supply duct (1) that extends from an external turbine (t) producing the compressed air flow； where said supply duct (1) defines a diffuser nozzle (s) which is coupled on the front face (2) of the dosing device, where both closed and individual longitudinal passages (p) and conductive hoses (c) and diffuser nozzles are born (d) that the machine has. It is distinguished because in relation to the respective mouths of the closed and individual longitudinal passages (p) are included the obstruction means that limit the pressure of the air flow that advances into the modifying device. of a closed and individual longitudinal passage inlet (p).“regulador da pressão pneumática e caudal, aplicado em um dispositivo dosador de material sólido, granulado, em pó, misturas e sementes previsto em máquinas do tipo semeadoras e fertilizadoras.” um regulador de pressão adequado para ser utilizado em um dispositivo dosador do tipo que compreende um tolbín (b) que está localizado em comunicação com o fundo da tremonha receptora do material (v), e possui uma abertura inferior de alimentação, embaixo da qual está disposto um conjunto de engrenagens dosadoras (e) montado em um mesmo eixo rotor transversal (e) que, com
