concepts. The control concepts used in fluid technology only constitute one part of all the possible variations. Due to the unfavourable framework conditions in fluid technology in terms of control technology

Hydraulic spring constant

Generic term in fluid technology for hydraulic fluids ( hydraulics ).

Fluid where the shear stress is proportional to the velocity gradient dv/ds: The proportionality factor η is referred to as the dynamic viscosity . Mineral oil is a Newtonian fluid, whereas lubricating

Collective term for fluid and gaseous media. Here fluids is above all a common term for hydraulic fluids and compressed air.

Fluids have the characteristic of dissolving certain amounts of gases. In mineral oil this ability increases linearly with pressure up to approx. 300 bar. Dalton's law states: V G = dissolved gas volume [...] volume at the reference pressure V öl = volume of fluid α = Bunsen coefficient for common mineral oils, for air 0.09 and for nitrogen 0.08 p = related absolute pressure p o = reference pressure (atmospheric

flame-resistant hydraulic fluids is comprised of water-bearing emulsions ( HFA and HFB fluids ) of aqueous solutions ( HFC pressure fluids ) and water-free, synthetic fluids in the HFD group . With the [...] is water-thin ( Table S 1 ). In most cases, the HFA pressure fluids (DIN 24 320) require a special structure, while HFC and HFD pressure fluids can be used to operate all construction elements in hydraulic

Responsibility for working on and drafting standards for fluid technology lies with the specialist fluid technology department at the Normenausschuss Maschinenbau (Standards Committee Mechanical Engineering [...] NAM). They work on all DIN, ISO and DIN ISO standards. In addition, recommendations with regard to fluid technology are also provided by CETOP and VDMA, and there are VDI guidelines too. A very comprehensive [...] uch 1993/1994" [O+P Design Manual 1993/1994] published by Vereinigte Fachverlage. The specialist fluid technology committee at the VDMA has also produced an overview.

uses the conversion, control, feedback control and transmission of energy by means of a fluid or gaseous hydraulic fluid to solve drive tasks.

Refers to the supply and discharge of the pressure fluid in pumps/motors through the inside of the displacement unit. For example, with valve plate controlled radial piston machines where the pistons are
