A group with the category of slow speed high torque motors which achieves its high torque by having each displacement unit perform several strokes (between four and eight or so) per revolution. These

Fire-resistant fluids based on water with 2 to 5% concentrate intended to give the water a minimum level of protection against corrosion and wear. Depending on the composition of the concentrate, emul

The understanding of some processes in fluid technology is improved if use is made of the analogies that exist between electrical and hydraulic laws. Given specific boundary conditions, it is possible

Many of the additives contained in mineral oil act like a vulcanising agent on elastomers. For this reason vulcanisation can occur at high temperatures; this action is termed ageing. The consequence o

Memory location number for the unambiguous identification of a memory location. The number of elements from a finite quantity of words for the identification of storage cells (memory locations) in con

Pressure for which devices or systems are calculated under defined conditions to obtain functionality (see also DIN 2401, Part 1). The calculated pressure can be definitive for the operating pressure

Measurement of signals at regular intervals, e.g. controlled variables.

Determination of the ongoing position change of a functional element on an axis (e.g. the piston of a cylinder or valve ) and feedback for processing in a closed circuit position control system . The

Continuously adjustable valve is the collective term for valves such as proportional valves , high response proportional valves and servo valves, which can be continuously adjusted .

Variable pump that pans from +max, though zero, to –max flow rate . Thus the suction line becomes the pressure line and vice versa without changing the rotating direction ( Figure R 27 ). Reversing pu
