Abstract
Perfeccionamientos en transmisiones infinitamente variable por polea y correa de transmisión, controlable por presión de fluido hidráulico, especialmente, en sistemas para accionar un aparato por medio de un motor impulsor y una trasmisión infinitamente variable con un miembro de transmisión sin fin que discurre sobre, por lo menos, dos poleas en forma de "V", en donde las distancias multas de las roldanas cónicas son hidráulicamente ajustables y en donde por medio de una bomba se proporciona fluido hidráulico para controlar para controlar la relación de transmisión, caracterizados porque la bomba es accionado por el motor impulsor y porque un embrague entre el motor impulsor y la transmisión variable es accionado hidráulicamente por medio de fluido proporcionado por la bomba y cuyo fluido es controlado mediante una válvula reductora y una válvula controlada en dependencia de la presión del fluido proporcionado por la bomba, de modo que el embrague solo es activado en caso que exista suficiente presión de fluido para que funcione la transmisión variable.
