Valve that is in parallel with a hydraulic unit and that permits the pressure fluid to bypass this unit under certain circumstances. Example: Pre-loaded check valve that is in the secondary flow for a

that radial forces, the so-called preload , are produced that make it impossible for the hydraulic fluid to flow around the seal even in the unpressurised state. With increasing pressure increasingly large

loss is the most important source of loss in hydraulic systems. It arises due to the of the pressure fluid in the pipes and the devices, and also due to mechanical friction losses (e.g. in guides or at seals)

They rely on the following compounds: Phosphoric ester (HFD R), currently the most widely used HFD fluid; performs worst in terms of fire resistance, however. Chlorinated hydrocarbons (HFD S). Only used

the total pressure , i.e. the overall figure for the static and dynamic pressure associated with a fluid flowing at a subsonic rate. The pitot tube consists of a tube at a 90° angle, whose arm lies parallel

For fluid valves there are a number of actuation types: Manual actuation: Actuation using a hand or foot (including manual override). Mechanical actuation using levers, plungers and/or rollers and springs

individual devices with the aid of temperature and pressure measurements . It uses the hydraulic fluid to carry the information and is based on energy contents and balances. It does not depend on the

Fluid seal for rotating shafts that comprises two elements made of non-elastic materials that are pressed against each other by spring force. One element rotates with the shaft, while the other is mounted

the dynamic pressure principle (dynamic pressure probe) and the variable area principle are used in fluid technology . They work indirectly and can be very small. Procedures for measuring the duration with

Ability of a hydraulic fluid to cover the surface over which it is distributed to a greater or lesser degree. Hydraulic fluids with good wetting ability adhere better to the surface. As a consequence the
