Pressure in an auxiliary circuit fed by the main circuit of a system, in which the pressure is lower than the primary pressure . This is generally achieved using a pressure-reducing valve .

Individual pressure compensator

Directional valve with six ports: In addition to the four ports A, B, P and T, in the centre position, a continuous line is formed for the flow rate to downstream consumers ( parallel connection ( Fig

A system is able to handle oscillations –– i.e. oscillations may occur –– if a periodic exchange of energy takes place between two energy stores (spring-mass system, e.g. a hydrostatic transmission, i

Exchanges between different energy forms, which take place more or less without hindrance. In hydrostatics, these are the kinetic energy of moved masses and the potential energy of the pressured liqui

In the case of three-directional valves, in the centre position, all ports can be connected to one another –– and therefore with the workflow (requires negative overlap).

In several areas of hydraulic systems, the flammability of the mineral oil constitutes a high risk. The group of flame-resistant hydraulic fluids is comprised of water-bearing emulsions ( HFA and HFB

pipe screw fitting

Device for turning movements (swivelling) at a limited angle (approx. 60° up to a maximum of 360°). A distinction is made between ( Figure S 41 ): The most simple construction type, which requires the

Value which a variable should have at the time under consideration and under the specified conditions (DIN 19 226). In electro-hydraulic control technology, this value is always an electrical variable
