    Abstract: Provided is an engine that includes a first member (piston rod (112a)), a second member (crosshead pin (114a)), a first hydraulic pressure chamber (168a) formed between facing parts of the first and second members, and a hydraulic pressure adjustment mechanism (196). The hydraulic pressure adjustment mechanism has a plunger pump (182) having a pump cylinder (182a) and a plunger (182b) and configured to supply hydraulic oil in the pump cylinder to the first hydraulic pressure chamber by pushing the plunger into the pump cylinder. The plunger pump moves in a stroke direction along with a piston and a power transmission section, and the plunger is pushed into the pump cylinder by receiving a reaction force opposite to reciprocating forces of the piston and the power transmission section.

    Abstract: An electro-hydraulic circuit enabling two mechanical devices to shadow each other's movements without any direct mechanically-operative linkage between the devices. The two devices incorporate matching sets of hydraulic actuators for inducing movements of movable components of the devices. For each actuator in a given one of the devices, a system of electronic sensors and hydraulic valves, in conjunction with a central processing and control system, keeps track of the physical positions and configurations of the actuator and the corresponding actuator in the other device, and what the status of the actuators should be in relation to each other. If an actuator associated with one device is moved by an external force, a corresponding actuator in the other device moves in response to that external force, with proportionate direction, speed, and force.

    Abstract: A pressurised fluid supply system (1) for an agricultural vehicle (1a) includes a fixed displacement pump (2) and a tank (3) to receive fluid. A first valve assembly (20) is arranged to adjust the pressure differential of the supply system, whereby the system provides two pressure differential levels and at least one of those results in a fluid flow in the direction from the pump (2) to a consumer coupling (5a). An amplifying valve (41) is arranged to superpose a load sensing pressure signal of an external consumer (4) of the fluid supply system with the pump pressure. The amplifying valve (41) is provided with first and second tank connections respectively including first (43) and second (44) valves to limit the fluid flow in the tank connection.
