摘要： A method and system for operating a machine having first and second movable elements, first and second hydromechanical movers for moving the first and second movable elements, respectively, and first and second hydraulic pumps linked to the first and second hydromechanical movers, respectively. Movement requests for moving the first and second movable elements are processed such that the movement command to the second hydromechanical mover is reduced by a variable amount based on the magnitude of the first movement request. For commanded first hydromechanical mover movements below a certain level, flow to the second hydromechanical mover may optionally not be reduced.

摘要： A hydraulic system includes an actuator, a pump, rod side and cap side fluid connections between the pump and the rod and cap side chambers, respectively, at least one selectively actuatable regeneration valve that selectively provides flow from the cap side fluid connection to the rod side fluid connection, and a controller. The controller controls the pump to selectively vary the flow rate of the pump in response to a commanded motion to control movement of the piston. The controller actuates the regeneration valve during a retraction of the piston into the cylinder when pump is acting as a motor.

摘要： A tilt and trim device for an outboard motor includes a tilt cylinder and a trim cylinder arranged to raise and lower the outboard motor, a reserve tank, an oil route arranged to allow the tilt cylinder to communicate with the reserve tank, and a branch oil route branched from the oil route and arranged to communicate with the trim cylinder. At least one hydraulic pressure adjustment mechanism is arranged to adjust the hydraulic pressure applied to the trim cylinder via the branch oil route to be equal to or lower than a pressure resistance of the trim cylinder when the outboard motor is forcibly lowered by an external force from a tilt range in which the outboard motor is raised or lowered only by the tilt cylinder. The tilt and trim device is operative to prevent deformation of and damage to a trim cylinder by suppressing the hydraulic pressure applied to the trim cylinder to be not greater than a specified pressure value even when the outboard motor is rapidly lowered from a tilt range, and a high hydraulic pressure from the tilt cylinder is returned in the direction of the trim cylinder.

摘要： The invention relates to a scavenging valve for a closed hydraulic circuit. A valve piston (40) is arranged in a longitudinally displaceable manner in a clearance (36) in a valve housing (35). Said scavenging valve (21) has at least three pressure spaces (41, 42, 43) which are constructed in an axially consecutive manner. Two of said pressure spaces (41, 42, 43) can be connected to one another other at a time in dependence upon a relative position of the valve piston (40) in relation to the valve housing (35). In order to interrupt the connection between the pressure spaces (41, 42, 43), a sealing element (44, 45), which effects sealing against a valve-seat face (50) constructed in the housing, is provided in each case.

摘要： The invention relates to a hydraulic drive, especially for two-cylinder thick matter pumps. Said hydraulic drive comprises at least one main pump (10) embodied as a hydraulic variable displacement pump, and two hydraulically actuatable drive cylinders (20, 22) that are each connected to a connection line (16, 18) of the main pump (10) by means of pump connections mounted on one end thereof, forming a closed hydraulic circuit, and communicate with each other at the ends thereof opposing the pump connections (24, 26) by means of a swinging oil line (28). The hydraulic drive also comprises a feed pump (42), by which means pressurized oil is fed from an oil tank to the current low-pressure side into the hydraulic circuit, and a flushing branch (52), by which means a flushing oil flow is branched off from the current low-pressure side under a limited pressure into the oil tank (44). In order to avoid low-pressure influxes during the reversal process of the main pump (10), the flushing oil flow is blocked and then released in a time-delayed manner during each reversal process of the main pump (10), independently of the differential pressure in the connection lines.
