Title:
液圧デバイスおよびそれを作動する方法
Document Type and Number:
Japanese Patent JP6772341
Kind Code:
B2
Abstract:
To provide a preferable fluid pressure device and a method for actuating the same.SOLUTION: The disclosure comprises a fluid pressure apparatus and a method for double actuation of a fluid pressure device. Some apparatus comprises a fluid pressure device having a first fluid pressure actuator and a second fluid pressure actuator, where the first and the second fluid pressure actuator has at least a first and a second fluid cavity and a piston respectively. Some apparatus also comprises a controller coupled to the fluid pressure device. In some embodiment, the controller is configured to receive fluid pressure fluid from a fluid source via at least 2 parallel fluid pressure line coupled to the controller, select a first fluid pressure line of at least 2 parallel fluid pressure line, apply pressure to the first piston and transfer fluid pressure fluid from selected first fluid pressure line to the first cavity of the first fluid pressure actuator to actuate the fluid pressure device.SELECTED DRAWING: Figure 1
