摘要： Two synchronous hydraulic polyphase motor-generators with axial cylinders are connected by rigid or flexible pipes. One functions as a generator, the other as a motor to transmit torque and power. Sinusoidal piston motion is developed without the use of cams. The pistons cause columns of fluid to alternate between motor and generator, producing synchronous rotation. Apparatus for synchronizing, coupling and decoupling the motive force are disclosed.

摘要： The invention relates to a method for adjusting a displacement pump that has a variable volume flow rate in an internal combustion engine. Said method comprises the following steps: the displacement pump is driven; the fluid is conveyed to the consumption points in the internal combustion engine; at least one characteristic value is determined from the exhaust gas flow of the internal combustion engine; said characteristic value is forwarded to a control device as an actual value signal; the actual value signal is compared to a given target value; a control signal is preprocessed from the deviation between the actual value signal and the target value; the control signal is fed to an actuator; the volume flow rate of the displacement pump is modified by means of the actuator in accordance with the control signal; the steps of the method are repeated until the actual value signal is identical to the target value.

摘要： An axial piston micropump is disclosed, having a cylinder drum, in which several cylinders are provided a swash plate, with respect to which the cylinder drum is rotatable. It is desirable for such a micropump to have a small displacement combined with a long service life and in which the displacement or delivery volume can be achieved with great accuracy. For that purpose, at least two cylinders are provided, of which at least one is in the form of a working cylinder which has an associated working piston, while at least one other cylinder is in the form of a balance cylinder and has an associated balance piston.

摘要： A system to generate and control a three-dimensional (3D) surface may include a surface supported by a plurality of actuating units, a control center, and a common media tank. The control center may include a movement control assembly that has a plurality of movement control unit, and each movement control unit is configured to control the movement of a corresponding actuating unit. In one embodiment, a predetermined amount of medium, such as air or liquid, is arranged in each actuating unit. The surface can be actually considered an array of small pieces divided from the surface, and supported and actuated by the actuating units. Since the control of the surface is through the control of every single piece thereof, the control of the surface would be more precise if the surface can be divided into more pieces.

摘要： A hydraulic fan drive for a cooling system of an internal combustion engine, in particular a diesel engine of a mobile working machine or a construction machine, is configured to be switched off for a short time or by way of a transition in dependence on a load of the internal combustion engine. A shut-off valve, which is arranged in a working line connecting a variable-displacement pump to a fan motor, is configured to switch off the fan drive. The fan drive is further configured to be switched off by rotational speed monitoring of the internal combustion engine.

摘要： A variable flow pump includes: a housing with inlet and outlet chambers interconnected by a main bore and a non-rotating cylinder block positioned in the main bore. The cylinder block includes: a central bore communicating with the inlet chamber; cylinder bores arrayed around the central bore; first feed passages interconnecting the inlet chamber and the cylinder bores, defining a bypass flowpath between the cylinder bores; and at least one discharge valve disposed at the second end which permits fluid flow from the cylinder bores to the discharge chamber but prevents opposite flow; Pistons are disposed in the bores. A shaft is coupled to the pistons so as to cause them to reciprocate through an axial pump stroke when the shaft is rotated. A mechanism is coupled to the cylinder block which modulates the axial position of the cylinder block within the housing, varying the size of the bypass flowpath.
