oil supply in which the pressure in the manifold is only applied by variable pumps that are equipped with pressure controllers. The size necessary for the pumps is based on the sum of the individual requirements

control for an actuator with two type A hydraulic half bridges. For example, the control of a hydraulic cylinder with a dual effect with a continuously adjustable directional valve with 4 control edges, which [...] which all have a negative overlap ( Figure V 25 ). The valve control with four edges is particularly important when copying, where it enables maximum force amplification. However, it requires a high level

an AC generator supplies a with a supply voltage with a constant amplitude and frequency. Where the transducer is strained at the outlet of an amplitude-modulated AC signal with the frequency of the supply [...] supply voltage, which is demodulated and amplified in the amplifier. Measuring amplifiers with carrier frequency are required for inductive transducers and can also be used in resistive systems.

control valve is proportional to the product of Q v and the load pressure p L: With all other methods (that is also with continuously adjustable valves) Q v must be reduced via the pressure-limiting valve [...] Control of the flow rate of a hydraulic system by flow resistances in general with the objective of controlling the velocity of a cylinder or motor. For this purpose flow valves , manually controlled [...] proportional or high response proportional valves are used (Figure D 46) . In a hydraulic system with constant pumps the flow rate not required Q V (Q V = Q 1 – Q N) is fed back to the tank (Figure D

system several loads (drive elements) are supplied by one drive power pack. The fluid power system with main pipe can combine such loads, which do not interact, because e.g. they come in succession ( drive

Control system on which the setpoint remains unchanged over an extended period apart from occasional adjustments (according to DIN 19 226). The primary task of such a feedback control is to regulate o

Construction design

Central position for valves with three switching positions . With directional valves , it is generally arranged with the help of centring springs and then becomes the initial position . Around 14 variants [...] valves, with common ones being centre position blocked; all working openings are closed ( Figure M 26 a ), open-centre position ; all working openings are connected with each other and with the process

displacement chamber with a type A hydraulic half bridge (adjustable input and output resistance); use of both control edges of a continuously adjustable 3/2-way directional valve with negative pressure. [...] Together with a differential cylinder with an annular area pressurised at operating pressure (replacement circuit for hydraulic bridge D), the two edge control enables movement control. One example is [...] than the valve control with four edges , as only two control edges have to be adapted to one another. However, it does not achieve the force gain and accuracy of a valve control with four edges . 2. Hydraulic
