“Beginners All Purpose Symbolic Instruction Code”. An easy to learn programming language in which all variables are valid in the entire program, unlike Pascal. However, this aspect makes writing clear

A programming language for programmable logic controllers (PLC) in which the control functions are listed in the form of statements. The statement list is internationally standardised in IEC 1131-3.

Smallest cross-section in the port bore on a device.

Gap between two chambers with different pressures. To prevent leakage either the gap must be designed such that no pressure flow can be produced ( gap seal ) or special elements are used, the seals. I

Size (possibly limit value) of the axial and/or radial load of the shaft of hydraulic pumps or hydraulic motors .

Growth of a variable in identical individual stages Δ s .

Device for the oil mist lubrication of compressed air whereby lubricating oil is allocated directly to the load based on the quantity and impulse sequence and independently of the air flow. This favou

Signal range in which the signal input , signal linking and signal output use hydraulic components. Hydraulic signal technology is very expensive and only suitable for a few linking applications given

Actuation whereby switching movements are triggered by a flow of hydraulic oil and - depending on the design - the pressure alone or a combination of pressure and flow rate take care of actuation.

Short term for hydraulic oils with additives designed to provide protection against ageing, corrosion and wear. Used where increased wear is expected, as may be the case when high levels of pressure a
