Hakuteksti "pumpe".

Hydrostatic transmission involving a pump combined with a motor in a block design. In general, stationary forms of hydrostatic transmission are designed as an integral hydrostatic transmission whereby

System in which the pressure at the hydraulic pump remains constant regardless of the flow rate and how high the load pressure is. Strictly speaking, this is only really the case with: controls with throttles [...] maintained by allowing any oil flow not required to flow away via the pressure-limiting valve ; variable pump with pressure controller which adjusts its delivery flow in line with consumption so the pressure [...] although they offer the advantage that loads connected in parallel can also be operated with one pump at the same time (e.g. parallel circuit ). In the field of electro-hydraulic control technology, they

vehicle drive which generally operates in a closed circuit with primary control (pump control) or primary and secondary control (pump and motor control). If a suitable form of control is used (e.g. automatic

directional valves (proportional, high response proportional or servo valves ). If a pump control with variable pump is used, worse dynamic performance is obtained, however also lower losses.

springs. Example: mechanical feedback from servo valves ( barometric feedback) or in the event of pump adjustments.

Pump (motor) with several pistons (as rule 7 to 11) that are arranged parallel to the drive shaft. The pistons are actuated by a swash plate or a drive flange ( inclined axis ). These two designs differ [...] together with the cylinder drum remain free of torque. Along with these two designs the swash plate pump is also an axial piston machine. However, it is used comparatively infrequently. Axial piston machines [...] the control disc (automatically adjusting gap!) compared to the pintle valve on the radial piston pump. Today they therefore cover roughly 80 % of the demand for high-pressure piston pumps.

Pump piston with a spherical piston area which uses the piston rings provided for sealing purposes. The piston shaft — unlike the spherical piston — is conical in shape and is responsible for taking the

"Electronic Flow Sharing" describes the flow rate distribution of the pump flow to the individual consumers in a hydraulic system by means of electronic control. Flow sharing addresses the problem of [...] undersupply in hydraulic systems. Undersupply in this case means that a hydraulic pump cannot provide sufficient Output volume for all valves. By means of "flow sharing", the available delivery volume [...] This can be implemented as required with the help of electronic flow sharing. Example: A hydraulic pump can deliver 100 l/min. Two consumers (actuators) are to be supplied. A problem arises as soon as both
