HYDRAULIC DEVICE AND PRIME MOVER DEVICE |
摘要 |
An object of the present invention is to prevent breakage of a unidirectional filter part for high-pressure oil. A hydraulic device 100 supplies oil to a high-pressure oil channel L1 and a low-pressure oil channel L2 from an oil tank 102 via a supply pump 104. The hydraulic device 100 includes an accumulator 106 capable of accumulating a hydraulic pressure of the oil supplied to the high-pressure oil channel from the supply pump; a filter part 120 disposed between the supply pump and a connection point N1 at which the high-pressure oil channel connects to the accumulator, along a direction in which the oil is supplied; and a check valve 110 capable of preventing a backflow of the oil to the filter part, and disposed between the filter part and the connection point. |
