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

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

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

In fluid technology electro-mechanical used to actuate valves are often referred to as solenoids. These are not permanent magnets, but are electromagnets. An electrical input signal (voltage or current) [...] today apply a compressive force. The return to the initial position is generally via spring force. In fluid technology DC solenoids (voltage or current) and AC solenoids (voltage or current) are available as

digital signal processing is increasingly dominant, because the majority of measuring procedures in fluid technology are analogue, it is necessary to use an A/D converter .

The cylinders have two line connections that are separate from each other. By feeding the hydraulic fluid through the two connections, the piston can transfer tensile and compressive forces in both stroke

feedback control technology as a test function to determine the transfer behaviour of a system (). In >fluid technology, ramps are primarily integrated in the activation of> proportional valves in order to adapt

Circular ring with an almost perfectly round cross section which is mainly used in fluids technology to seal machine parts when at rest ( Figure O 11 ). Its sealing action is achieved through axial or

Velocity of the transmission of pressure in a fluid (speed of sound). It is dependent on the bulk modulus K of the medium and its density ρ: In air in the normal state it is 333 m/s. In mineral oil it
