Abstract

Un dispositivo para fluidos incluye una placa circular variable adaptada para movimiento entre una primera oposición y una segunda posición. Un pistón de control se adapta para selectivamente mover la placa circular variable entre las primera y segunda posiciones. Una válvula de control esta en comunicación de fluidos con el pistón de control. La válvula de control incluye un manguito definiendo una perforación de carrete, por lo menos un pasaje3 de entrada de fluidos en comunicación de fluidos con fuente de fluidos y por lo menos un pasaje de control en comunicación de fluidos con el pistón de control. El pasaje de fluidos de control incluye una abertura en la perforación de carrete. Un carrete es dispuesto en la perforación de carrete del manguito. El carrete incluye una superficie de medición que selectivamente comunica fluido entre el pasaje de entrada de fluidos y el pasaje de fluidos de control. La superficie de medición tiene un primer extremo y un segundo extremo. La superficie de medición teniendo una superficie ahusada dispuesta entre el primer y segundo extremos.
