Abstract: Control fluid power apparatus and related methods are disclosed. An example control fluid power apparatus includes a first housing having a first piston defining a first chamber and a second chamber, where the first chamber receives a control fluid and the second chamber receives a process fluid from a process system. The first chamber is oriented above the second chamber when the control fluid power apparatus is coupled to a control valve assembly. A second housing has a second piston defining a third chamber and a fourth chamber, where the third chamber receives the control fluid and the second chamber receives the process fluid. The third chamber is oriented above the fourth chamber when the control fluid power apparatus is coupled to the control valve assembly.

Abstract: The shuttle action evaluating unit determines that the vehicle is in a shuttle action when the direction relative to the position of the forward/reverse travel operating member differs from the travel direction of the vehicle. The target input shaft torque determination unit determines a target input shaft torque. The target output shaft torque determination unit determines a target output shaft torque so that a deceleration force for decelerating the vehicle is generated on the output shaft of the power transmission device in a state in which connection and disconnection states of the forward travel clutch and the reverse travel clutch are maintained at the state before the start of the shuttle action when the shuttle action is started. The torque-balance information is stored in a storage unit and defines a relationship between the target input shaft torque and the target output shaft torque so as to achieve a balance of the torques of a power transmission device. The command torque determination unit uses the torque-balance information to determine torque commands to the motor from the target input shaft torque and the target output shaft torque.

Abstract: Provided is a hydraulic circuit capable of solving a problem without having to solve by switching circuits that leads to operability deterioration, the problem being that a speed of a hydraulic cylinder lowers when an accumulator pressure rises, and realizing efficient reuse of energy. The hydraulic circuit has: main pumps (12, 13) driven by an engine (11); a boom cylinder (7cl) including a piston (7cp) operating by hydraulic oil supplied from the main pumps (12, 13), one chamber (7ch) and the other chamber (7cr) respectively partitioned and formed by the piston (7cp); an accumulator (61) accumulating pressure of the hydraulic oil extruded from one chamber (7ch) of the boom cylinder (7cl); and an assist pump motor (15) suctioning the hydraulic oil from the accumulator (61) when pressure continues to be accumulated in the accumulator (61) and the accumulator pressure rises.
