Abstract
"CONJUNTO DE PISTãO". Uma bomba hidráulica inclui um alojamento, pelo menos dois pistões montados no alojamento para girar em relação ao alojamento, e um braço de transição acoplado a cada um dos pistões para girar com eles. O braço de transição é ajustado a um ângulo predeterminado em relação a um eixo geométrico longitudinal da bomba. Um mecanismo de ajuste ajusta o braço de transição no ângulo predeterminado. Um cilindro está montado dentro do alojamento para girar em relação ao alojamento e define as cavidades de bomba para receber os pistões. Uma válvula de face define os canais de entrada e de saída em comunicação de fluido com as cavidades da bomba. Um aparelho para variar o volume de saída de um conjunto de pistão inclui pelo menos dois pistões, um braço de transição acoplado a cada um dos dois pistões, e um membro girável. O braço de transição inclui um pino de nariz, e o membro girável está acoplado ao pino de nariz do braço de transição. Uma posição radial do pino de nariz em relação ao eixo geométrico de rotação do membro girável é ajustável enquanto que o membro girável permanece axialmente estacionário.
