Abstract

MáQUINA DE FLUXO HIDRODINáMICA, E, PROCESSO PARA O ACIONAMENTO DE UMA DAS DUAS RODAS OU UM ACIONAMENTO RECìPROCO DAS DUAS RODAS DE UMA MAQUINA DE FLUXO HIDRODINáMICA. A invenção refere-se a uma máquina de fluxo hidrodinâmica, em particular retardador, com uma roda primária com palhetas (1) e com uma roda secundária com palhetas (2), que conjuntamente formam um espaço de trabalho (3) que pode ser cheio com um meio de trabalho. Pelo menos uma das duas rodas (1, 2) pode ser axialmente deslocada, pelo menos com sua região parcial com palhetas (1.1), com relação à outra em uma tal maneira que ela pode ser comutada entre uma primeira posição próxima, em que ela se opõe diretamente axialmente à outra roda, e uma segunda posição afastada, em que ela é disposta com uma maior distancia axial a partir da outra roda do que na primeira posição. A máquina de fluxo hidrodinâmica inventiva, em particular, retardador, é caracterizada pelo fato de que inclui as seguintes características: uma conexão de compensação de pressão de condução de fluxo (4) é prevista entre o espaço de trabalho (3), o qual é disposto no lado frontal axial da roda deslocável (1), e um espaço de compensação (5), o qual é disposto em um lado traseiro axialmente oposto ao lado frontal da roda deslocável (1); a conexão de compensação de pressão (4) é disposta de tal maneira desembocando no espaço de trabalho (3) e no espaço de compensação (5) que ela é completamente ou substancialmente completamente bloqueada pelo menos indiretamente por meio da roda deslocável (1), quando a roda deslocável (1) se encontra na primeira posição, ao passo que ela é liberada pelo menos indiretamente por meio da roda deslocável (1), quando a roda deslocável (1) se encontra na segunda posição afastada.HYDRODYNAMIC FLOW MACHINE, AND PROCESS FOR DRIVING ONE OF THE TWO WHEELS OR A RECYCLE DRIVE OF THE TWO WHEELS OF A HYDRODYNAMIC FLOW MACHINE. The invention relates to a particularly retarded hydrodynamic flow machine with a vane primary wheel (1) and a vane secondary wheel (2) which together form a workable space (3). with a working medium. At least one of the two wheels (1, 2) may be axially displaced, at least with its vane partial region (1.1), relative to the other in such a way that it may be switched between a first near position, wherein it directly opposes axially to the other wheel, and a second spaced apart position, where it is arranged with a greater axial distance from the other wheel than in the first position. The inventive, particularly retarding hydrodynamic flow machine is characterized by the fact that it includes the following characteristics: a flow conduction pressure compensation connection (4) is provided between the workspace (3) which is arranged on the axial front side of the sliding wheel (1), and a compensating space (5) which is arranged on a rear side axially opposite the front side of the sliding wheel (1); the pressure compensating connection (4) is arranged in such a way as to flow into the work space (3) and the compensation space (5) that it is completely or substantially completely blocked at least indirectly by means of the sliding wheel (1), when the displaceable wheel (1) is in the first position, while it is released at least indirectly by means of the displaceable wheel (1), when the displaceable wheel (1) is in the second displaced position.
