Title:
トラクタの外部油圧取出装置
Document Type and Number:
Japanese Patent JP3579225
Kind Code:
B2
Abstract:
A hydraulic pressure takeout apparatus for use on a tractor having a hydraulic device with right and left lift arms for raising and lowering a working implement. The hydraulic pressure takeout apparatus includes a valve assembly mounted on a hydraulic housing forming part of the hydraulic device, and between the right and left lift arms. With this construction, oil lines for transmitting pressure oil to the valve assembly are not exposed to the outside, which is particularly advantageous where the tractor frequently engages in an operation on wet, soft soil. The valve assembly may be maintained with facility, and oil leakage is unlikely. Where the valve assembly is mounted on the hydraulic housing through a spacer defining connecting oil lines therein, oil leakage is prevented with increased assurance. The valve assembly may include a plurality of valves stacked one upon another to enable multiple or multi-purpose hydraulic pressure takeout.
