Abstract

<B>"SISTEMA DE TRANSFERêNCIA DE FLUIDO"<D>. A presente invenção se refere a um sistema de transferência de fluido, incluindo duas câmaras de transferência de fluido alongadas (10, 10'), disposições de entrada e saída de fluido em cada extremidade de cada câmara, válvulas de entrada e saída unidirecionais dirigidas opostamente na disposição de entrada e saída em uma primeira extremidade de cada câmara para controlar o fluxo de um fluido transmitido (22, 24, 22', 24') para dentro e para fora da câmara, válvulas comandadas de entrada e saída dirigidas opostamente na disposição de entrada e saída na segunda extremidade de cada câmara para controlar o fluxo de um fluido transmitido (18, 20, 18', 20') para dentro e para fora da câmara, uma disposição de compensação de pressão incluindo uma portinhola em cada uma das válvulas comandadas, um atuador (62, 62') em cada válvula comandada que é adaptado para abrir e fechar a válvula e a portinhola de compensação de pressão na válvula, e um sistema de controle (100, 102) que é conectado aos atuadores de cada uma das válvulas comandadas para proporcionalmente abrir e fechar as válvulas de entrada comandadas de cada câmara, na fase exatamente oposta entre si e para abrir e fechar as válvulas de saída de câmara comandadas, para assegurar um completo volume de fluxo de fluido de transmissão contínuo através do sistema, na dependência das posições relativas dos fluidos de transmissão e transmitidos em cada uma das câmaras de transferência.<B> "FLUID TRANSFER SYSTEM" <D>. The present invention relates to a fluid transfer system, including two elongated fluid transfer chambers (10, 10 '), fluid inlet and outlet arrangements at each end of each chamber, unidirectionally directed inlet and outlet valves in the inlet and outlet arrangement at a first end of each chamber to control the flow of a transmitted fluid (22, 24, 22 ', 24') into and out of the chamber, controlled inlet and outlet valves directed opposite the arrangement inlet and outlet at the second end of each chamber to control the flow of a transmitted fluid (18, 20, 18 ', 20') into and out of the chamber, a pressure compensation arrangement including a hatch in each of the controlled valves, an actuator (62, 62 ') on each controlled valve that is adapted to open and close the valve and the pressure compensation port on the valve, and a control system scroll (100, 102) that is connected to the actuators of each of the controlled valves to proportionally open and close the controlled inlet valves of each chamber, in the exact opposite phase and to open and close the controlled chamber outlet valves, to ensure a complete volume of continuous transmission fluid flow through the system, depending on the relative positions of the transmission fluids and transmitted in each of the transfer chambers.
