Abstract
"SISTEMA DE CONTROLE HIDRáULICO". é apresentado um sistema de controle hidráulico para amortecer as vibrações decorrentes da condução de uma máquina móvel, compreendendo um cilindro elevador suportando uma ferramenta de trabalho, as cãmaras de cujo cilindro podem ser conectadas com uma fonte de fluido ou um tanque através de um conjunto de válvula de controle. O sistema de controle hidráulico tem um conjunto de válvula de amortecimento incluindo uma válvula de controle no qual uma válvula de retenção é integrada através da qual uma câmara do lado inferior do cilindro elevador é conectável com um acumulador hidráulico. Na função de controle de pressão o acumulador pode ser conectado com um tanque para que a pressão do acumulador seja limitada a um máximo valor."HYDRAULIC CONTROL SYSTEM". A hydraulic control system for damping vibrations arising from driving a mobile machine is provided, comprising a lift cylinder supporting a work tool, the chambers whose cylinder may be connected to a fluid source or a tank through a set of control valve. The hydraulic control system has a cushion valve assembly including a control valve in which a check valve is integrated through which a lower cylinder chamber is connectable with a hydraulic accumulator. In the pressure control function the accumulator can be connected with a tank so that the accumulator pressure is limited to a maximum value.
